5	gum infection	Loose stools (worse than regular drinking will produce), slight headache (though this is on the same side as the gum infection - upper jaw). Took me 4 days to get a decent nights sleep, though this could be because i'm used to drinking every evening (which i'm no longer doing whilst taking them having read horror stories), been up regularly on these things for over 20 hours a day. Slight dizziness, though nothing worrying at all. I appear to have slight tunnel vision to, again nothing to get upset about (could be the lack of sleep i guess).	This pill tastes vile - very bitter/metalic indeed! Though i had no after taste a few minutes after swallowing it (wash it down with strong fruit juice). Being taken along with 500mg Amoxicillin 3x D & 400mg Ibuprofen 3x D. It appears to work very well indeed. The day after i started taking them i was no longer in severe pain, no massive headache or pressure in my jaw, all gradually decreasing. As each day has gone by things have improved dramatically. Taking the last pill inside of an hour, happy chappy tomorrow ;-)	M	43	5 days 400 3X D		5/31/2010
5	Diverticulitis	None		M	66	7 days 250 4X D		7/9/2010
5	Tooth infection	A bit of a upset stomach at the start of the course and a dry mouth now. No metallic taste or any other of the neuro-like symptons described by others.	The pills taste horrible but the infection seems to be going so I can't complain. Make sure you don't drink any alcohol with this drug - every web site stresses this.	M	40	7 days		11/7/2005
5	WISDOM TEETH EXTRACTION/ INFECTION	Headaches, depression, lack of energy, restlessness, shivering and sweats, aching all over, lack of motivation	I'm stopping a day short of the required dosage (3x200g for 5 days). I can't go on any longer - I just hope it's cleared the infection from the surgery up completely.	M	34	4 days		4/7/2006
5	Root (tooth) Infection	Mild visual disturbances on starting course, thirsty	Fantastic stuff - have taken metronidazole before and although it has mader me feel a little out of sorts in the past, it always clears things up really quickly which is important if you've got something painful like toothache!	M	29	1 weeks		11/23/2005
5	gum infection	Day one took two 400mg pills by accident, felt spaced out all day. Days 2-5, no major problems. Day six though, lithargic, tired, loss of appetite and severe stomach pains. Thank f**k only two more pills to take, and hope this sickness disappears as soon as.	Started to work that day and gum pains went away and got proper sleep for the first time in two weeks. This no drinking business is tough, how long after stopping can you have a beer?	M	28	7 days		11/22/2006 Email
5	Molar tooth abscess	No side effects at all - I was quite concened after reading other people experiences and delayed taking the drug as much as I could until the tooth pain was unbearable. Then I took it and there was no unpleasant taste, no side effects just great anti-biotic action. It started to work 12 hours after initial dose, just as it should and I am now finalising my first day.	I bet that the alcohol side effect is urban legend as well, just as some new research indicates. However, will not experiment ;-)	M	44	1 days		11/11/2006
5	abscess after root canal	Beginning the second day, some confusion, wooziness, metallic taste, loose bowel, depression	* The med worked well for the abscess but side effects were significant. I'm a retired physician who had neither prescribed nor used it before, but much more explicit caution needs to be given patients than 'merely' to avoid alcohol, as important as that is!	M	71	6 days		4/8/2007
5	Root canal treatment	I'm pretty tough but finished course 5 1/2 days out of 7. Sleeping problems, diarrhoea, stomach pain and continual nausea. Eye pain, tingling in face. General malaise. Very depressed didn't want to do anything. Especially first couple of hours in the morning. REALLY spaced out, like my head had pressure and was going to explode, I was panicking severely, went to emergency doctor for re-assurance, paranoia. Disorientation and unsteady on feet.	Never again, my problem has gone, but this has been hell. I've lost over a week's work, still don't feel completely right even after stopping the medication. Seriously scary stuff. I've never seen this board before. Doctors / Dentists should make it really clear how this stuff can F**k with your body and mind!!	M	44	5 days		6/4/2006
5	Gum imfection	The only side effect was delight which led me to surf the web to find out more about this drug.	I had 5 days of amoxicillin which did absolutely nothing for my painful problem, I had to suck food; then I was prescribed metronidazole and within 24 hours was feeling much better and within 48 was able to eat an apple.	M	58	2 days		10/6/2007 Email
5	Bacterial infection (spider bite)	Constant sickening metallic taste in mouth. Unbelievably bitter tasting pill. Constant headache that feels like a bad sinus headache. Lethargic. Loose, dark stool. Bouts of woozieness, sometimes bordering on severe disorientation; scary. Some insomnia.	Knocked that infection out of me quite effectively. Was taking it in conjunction with Cipro. Found out toward the end of the treatment that the bitter taste is undetectible if you take it in a spoonfull of chocolate syrup. One day to go...can't wait for it to be done. Am taking 500mg 3x/day.	M	54	14 days		7/15/2005
5	infection in wisdom teeth	mild taste in mouth	none really glad it helped	M	36	7 days		5/26/2003 Email
5	Tooth Infection	Hideous taste in my mouth all day,sleepless nights,lathargy, nausea, severe stomach cramps,dizziness,irratibility,confusion and the wierdest feeling of my skin itching. The infection seems to have cleared up but is was a battle to complete the course. The worst part was the taste constantly in my mouth.	As with any antibiotics you have to complete the course so get ready for a really uncomfortable week.	M	32	5 days		4/15/2005 Email
5	infection in tooth	bad taste in mouth. Urine dark orange. Appetite great etc. even the weather was better. Saved my tooth from root canal.		M	58	7 days		5/3/2007
5	Shigella	No real side effects. Only gas. Did NOT drink alcohol or even dealcoholized drinks, which doctor said leads to a lot of nasty side effects.		M	48	7 days		9/24/2007
5	Gum infection	No bad side effects - infection cleared up by day 6 of 7. The tablets have a typical (slightly unpleasant) metallic antibiotic taste.	I am sorry that others have had bad side-effects, and I wonder about the true statistics.	M	55	7 days		5/2/2007
5	Parasitic Infection	700mg,3X per day for 10 days. I thought it was just me and I was being a wimp. Extremely light headed, lethargic, wild dreams, loss of appetite and weight, metalic taste. Not an easy treatment.	I find it hard to believe this drug is on the FAA's approved list. I would not pilot an aircraft while taking this medication.	M	56	5 days		3/3/2008
5	post op rectal infection	metallic taste, headaches, loss of appetite, stomach cramps,dark smelly urine. inability to sleep for more than a few hours at a time. felt generally low and anxious	horrible side effects but it sure cleared up the infection very fast. would take again if necessary but would also dread the side effects	M	47	5 days		5/25/2008
5	Giardia lamblia	None, except for discolouration of my urine. The text books describe it as yellow-green colour, but mine looked like Coke.	I had had the Gargia lamblia for 17 days before I started taking the metronidazone - don't ask! The dose was 1,000 mg twice a day, for three days. After reading some of the problems some of the rest of you had reported on this site I was a bit worried about side effects. I don't drink alcohol, so maybe that helped. I do need to be re-tested in two weeks time, but how I feel at the moment I expect the re-test is alright.	M	48	3 days		6/7/2009
5	uti and prostatitis	Exhaustion leading to sleeping 14 hour a day. Low back pain around waist. Some metallic taste. Reduced appetite but wish it had been more. Lack of focus and weird feelings.	Because I know about drugs, I figured out not do alcohol at all but did not get sufficient warning on this. But the drug really did cure my problem and I am very grateful.	M	73	7 days		9/27/2009
5	Root Canal	nausea, slight dizzyness, dry furry mouth.	The first time I took these tablets I was advised to eat plenty of pro-biotic yogurt which I did, so I had no problems. I forgot about the advice this time and experienced increasing side effects, the worst of which was the nausea. The tablets are very effective at clearing the infection though so I would say stick with them but take plenty of pro-biotics.	M	63	7 days		1/2/2010
5	Diverticulitis	Taking Metronizadole (3x/day, 500 mg tabs) with Ciprofloxacin (2x/day, 750 mg tabs). I am experiencing many of the affects of these drugs as described by others - dizziness, occasionally very dark stools and diarrhea, extremely bad taste in mouth, tiredness, headaches and depression. I generally sleep well. Learning that depression was a side-effect enabled me to put it in perspective. Try to avoid touching your tongue for any length of time. These medicines have terrible effects. I can't understate them. But they are said to be medically essential for my condition, and I will take them to the end which is two weeks. I have taken them on one other occasion. I am now at the half-way point of this course of treatment. Can't wait to finish!	I can't understate how happy I am that I found this page and that so many have contributed. Hearing what others have to say is invaluable.	M	65	14 days		1/9/2010 Email
4	Dental infection (abcessed tooth)	headache, bad mood	I am lucky , so far, because I have not had any of the stomach-related side effects and I have not yet experienced that dreaded "metallic taste" in my mouth. I am at the end of day #3, so I have 7 more days to go. The one thing that I do feel is a moody-anxiety-sorta angry feeling. I thought I was just being a big baby but I was glad to read that others had experienced this same feeling. Also, I seem to have this headache which is on-again / off-again and may be contributing to my crabby mood. The drug seems to be helping my gum infection , so that is good. I look forward to the end of this medication for several reasons ........ one of which is that I really look forward to being able to enjoy a glass of beer again ........ patience, they say.	M	47	10 days		11/12/2009
4	Throat Infection and Tosillitis	Lethargy....could sleep all day and night. Very hyper and lively guy, now flat, no energy. Smooth tongue, not eating much, horrible diahoria and vey smelly. Dark urine. mild nausea, loss of apetite, mild weight loss.. Pale. occasional 5 mins sweats. On a 10 day course combined with Penecillin following a hospital admission for Severe Throat infec. which may have been Tonsillitis, Absys, Quinsy, Glandular Fever....inconclusive.	If they sort out my problem, the sife effects may be worth it, is the dissapate quickly....but it really is not nice.	M	40	10 days		11/24/2009 Email
4	Dog bite	Dizziness and fatigue	I gave this a "4" but I also was given two intravenous anti-biotics in a hospital emergency room and if those did 100% of the work then I'd give this a "2".	M	58	10 days		11/29/2009
4	Appendicitis	Loss of appetite, always tired, irritable. Metallic taste in mouth. change in tastes of food. Anxiety	On day 12 of 14. This stuff really works, but at what cost? Taste is nearly unbearable; lingers for a long time after taking the pills. Pill dissolves so quickly I hardly have time to chug it down, and when I do, it always goes down the wrong way; tried breaking it in two and swallow in parts. Did I mention the taste? Developed a filmy coating on tongue that has been around since day 2 of treatment. Side affects have been a lot to deal with, but inflammation and pain have totally subsided. Hopefully the Docs will say the infection is gone so I don't have to repeat this experience. Does' anyone know of good alternative AB to metronidazole?	M	20	14 days		9/11/2009
4	Gut infection	Itchy skin feels like something is crawling under your skin. loss of appetite. Constant metallic taste. Wild dreams ( dreamt among others about Arsene Wenger getting shot outside the emirates honest).	If you can tough it out, it works. Rang boots pharmacy about side effects, they suggested I take anti hestamine for the itchy skin	M	30	7 days		10/16/2009
4	Diverticulosis	Loose, very dark stool; more frequent movements. Making me very anxious, depressed, and had several uncharacteristic bouts of near rage in the last couple of days. Very glad to have found this site to help understand what is happening to me!	I hope it is worth this. 1 more day of treatment.	M	47	7 days		10/28/2009 Email
4	Throat infection, Swollen uvula	Cracking headaches, generally feeling low and flu like	Make sure you drink lots of water. This is a strong antibiotic that will make you feel dreadful but if its making you feel bad, its doing the business.	M	37	7 days		6/20/2009 Email
4	Gum Infection	I have not met with any side effects. I am on day 3 of a 5 day course and the swelling in my gum is going down nicely		M	54	3 days		6/24/2009
4	Vaginitis with discharge.	I feel tired,confused with numdness and tiglind in the bottoms of my feet. (NO, I did not feel this way before treatment HAHAHA) Metalic taste in my mouth. (This is the worst)	I have been treated with this medications several times. I suffer from bouts of diveritculitis and this medicine with cipro works great for that. This is the first time I had this vaginitisis. The symptoms lessened and then went away in 3 days.	M	43	5 days		5/3/2009 Email
4	Giardia	Tingling in arms and legs first day..as well as a bit of dizziness. A bit more tired than usual.	It really feels like its working. After months of feeling horrible from Giardia...on just the 3rd day on the drug...I'm feeling so much better.	M	37	3 days		7/16/2009
4	wisdom teeth removal	upset stomach, felt really low in mood with negative thoughts, tiredness, insomnia, reduced appetite.	cleared up the infection but felt awful	M	26	5 days		6/13/2008
4	Gum infection	I can identify with many of the side effects listed by other consumers but nothing too bad. I expect to have some side effects with most medicines and sometimes wonder if it's worth it but when I consider what's ailing me and what the consequences of not beating this monster, I become more tolerant. I'm not suggesting that It's good for everyone but Don't throw in the towel right away. No pain, no gain, be well.		M	65	10 days		8/7/2008
4	tooth infection after extraction	made me really really pissed off and short tempered. and i slept in the middle of the day. thats all i can say really, and also swollow the tablet quick because it taste's of metal.	i was first given amoxicillin, this did not clear the infection, then went onto metronidazole antibiotic 200mg	M	28	5 days		9/13/2008
4	Tooth Infection	Haven't any side effects from taking this, actually had my first night of real sleep last night and I suspect this drug is finally starting to fight the infection as Penecillin didn't help	I like it, don't notice any of the side effects mentioned by other people here, I was warned of them but I feel fine, other than a sore tooth which does seem to be better today. Would definitly take them again	M	34	2 days		6/15/2008
4	Anaerobic G.U.M Infection	Mild groggy tiredness and weakness which worried me until I realised it must be a side-effect of this medecine rather than the infection. Know that I will feel A1 when the course ends in 5 days and takes the infection with it.	Can't make an omelette without breaking some eggs. Think how lucky you are to live in an age when infections can be treated so easily. Can't believe some of these whining saps. If you have a furry tongue use a tongue scaper and some dilute hydrogen peroxide mouthwash and some Hexylresorcinol pastilles (blackcurrant from Tesco). If you get digestive upset start eating muesli with bio-active yoghurt and if you don't like the taste for god's sake learn to swallow without chewing like a normal grown-up. Jeez what a pathetic infantilised society. Thank God I'm not a doctor I couldn't stand dealing with the terminally pathetic and their trivial whinging.	M	45	7 days		11/6/2008
4	Colon Infection (IBS)	500mg 3x per day. Horrible metallic taste in mouth. Better when drinking hot coffee or tea - worse with anything cold or water. Heart Palpitations and a general feeling of nervousness or anxiety from Day-1	About Day-10, I felt the medication was kicking-in as the chronic diarrhea stopped and stools were formed although they were soft. Major-League sore throat starting around Day 8 and continuing till the end (Day 14) and definitely a nasty looking white-coated tongue which psychologically added to the metallic taste. Glad it's over. Heavy Duty stuff - but I think it works.	M	56	14 days		3/16/2007
4	Dental Infection	Itchy rash, dark urine	Taking 500mg 4 times a day, finally saw relief from horrible dental pain on day 2. On day 6 of a 7 day course I woke up with red whelps in various places. The rash itches off and on but they are far easier to live with than the pain I was in.	M	38	7 days		6/3/2007
4	vaginal infection after surgery	Along with the furry tongue and disgusting metallic taste I am having the most awful panic attacks. Extremely anxious and my thinking is completely irrational. I feel like my whole world is coming to an end - even though I have a great life. Keep crying all the time. Cannot think straight.	They do not list depression and anxiety as a side effect - why not. Thought I was going mad until I found this page. Very funny because I was on this drug 3 years ago for an ear infection and at the time I got it into my head that I was going to die from the infection. I could not understand why I felt that way - but now I know. The problem is this drug works!!!	M	35	7 days		10/18/2007
4	diverticulitis	Metallic taste, some anxiety. Also, I have had some difficulty concentrating and have felt very drained. Interesting that others have had the same effects, makes me feel better.		M	56	8 days		11/6/2007
4	C. Diff due to Clindamiocin	Well it's day two, I feel like i'm in another world. I get the feeling that i'm having a panic attack, my vision is blurry, and i feel like i'm on narcotics. I was on Percoset with the clindamiocin, it kinda feels like that. I have EXTREME insomnia. I'm also very nervous i'm going to have the syptoms other people are talking about. I'm a smoker so the taste of metal isn't really there, the only thing i'm worrie about is the performance i'm going ot have at work. I can't afford to miss work. I have nausia and some loss ap. I'm a vegetarian which i hear helps with the consitpation, so at least i won't be bad in that department. I also have loss of labido. BUT! I haven't felt this good in about a month, hopefully the side affects are worth it.	I'm taking 500 mg 3 times a day, for 10 days.	M	20	10 days		11/28/2007 Email
4	Periodontal Infection	Continual revolting taste in mouth. Feel woozy and irritable. Loss of energy. Sore spots like ulcers in mouth and swollen/sore throat. Basically makes you feel ill.	Got rid of the infection very effectively, but finishing the course is a great relief. Appears to be the standard treatment for this kind of thing. Why can't they make it in capsule form so at least you don't suffer the vile taste?	M	49	7 days		3/29/2005 Email
4		Change tastes of food, water, even saliva. Gives a disgusting metallic taste to everything. You also have to be very careful to follow the warnings (intake with food, zero alcool, etc.)	Did the job of curing the infection yet i'm pretty happy to be over with it.	M	23	24 days		8/23/2002
4	Gingivitis	Felt like constant mild hangover	Fill mouth with water first, then pop pill in and swallow quickly or you will have bitter taste in your mouth all day.	M	35	7 days		9/25/2004
4	Toothache	Candida flare up, Face came up in hives and was very itchy, itchy it moist areas ie groin and between toes. Felt generally itchy. Funny taste in th emouth and throat, although not specifically metallic.		M	43	7 days		4/2/2004 Email
4	diverticulitis	Absolutely awful. And I am only on day 5 of 10. Bad metallic taste in mouth, dry mouth, almost think I am getting thrush, making my gastrinal problems worse, insomnia, headaches, dry cough. Will be so glad when I am done, if I can get there!		M	42	10 days		7/26/2005
4	Gum Infection	Was on a low dosage, felt a bit woozy but that was probably the painkillers i was taking. Main problem was the horrible metallic taste in the mouth, didn't start til just after i STOPPED taking the medicene, but it's not going away quickly unfortunately.	Worked wonders on the infection and this metallic taste is a walk in the park compared to the thumping pain of the infection.	M	23	7 days		8/2/2005
4	Infected Diverticula	The metallic taste was one thing but BY FAR the worst was the depression. I took this pill for 10 days and by day 5 I had a mental breakdown and was severly depressed for the remaining of the course (500mg x 3 per day). Also towards the end I had some stomach pain that prevented me from eating much (I had to force myself just so I would feel better). Good luck!!	I will say what helped was to drink A LOT of water when on this med and find someone to talk to about your depression, it will help you get through it!! Thanks God for this message board. Seriously if I had to do it again I probably would NOT take this simply because of the depressed feeling. If you know you get easily depressed ask for something else. I finished the course yesterday and still feel the ups and downs of depression.	M	27	10 days		6/2/2006
4	Tooth abscess	Dizziness and unsteadiness when getting up from laying or sitting, fatigue, dark urine, metallic taste, overnight extreme sweats (caused by infection or medicine?).	Pain went away in a day or so, but the side effects were difficult to deal with, especially with no alcohol for nine days. 4x500MG for 7 days.	M	65	7 days		12/3/2006
4	stomach infection / sinus	Good grief, but this medication is severe! I think I've had every side effect mentioned here that i've read so far. they include fever, depression, severe pain behind my eyes, bloating, feeling exhausted all the time, back pain, shooting pains in my hands and feet.	while the doctor initially prescribed it for what he thought was a bacterial stomach infection, it seemed to be addressing this chronic sinus infection that bactrim hadn't completely cured. so while i was glad of the healing that it was doing for my sinuses, i couldn't take the side effects after 4 days (i was supposed to use if for 7 days) and went to the doc who prescribed a 7day regimen of Levaquin instead. hopefully this will be easier on my body - but only time will tell. thanks to everyone who posted on here - i thought i was going insane for a while there.	M	46	4 days		12/11/2006
4	amoebiasis	metallic taste, always dizzy, urine is dark, constipation	Bad breath is gone	M	39	5 days		8/16/2005
4	Periodontal disease	Numbness in arms and lower back, headache in the morning, itchy skin. None of the other symptoms described by other users.		M	54	7 days		5/29/2006
4	dr said vaginal "ph" was off	Like you guys said - thank God I found this page! Bad taste in mouth, still lingers 5 days off med. Also general weird and out of it feeling. One night I took it before bed. I had eaten dinner but didn't take it "with food". I was up for 3 or 4 hours writhing in pain. Now I have pain in my stomach or small intestine area whenever I am hungry like an ulcer or gastritis.	Stopped taking after 5 days, lost 6 pounds and couldn't take the stomach problems. It appears to have worked even though I didn't finish the course. For those of you who had bv and it worked but you couldn't take the side effects, my ob said this med comes in a gel form you put "in there". Not convenient but less side effects.	M	36	5 days		12/21/2006
4	Gum infection	400mg Metronidazole with 500mg Amoxillin three times a day with or after food over seven days. Extreme tiredness, nausea, dark urine, sadness, depressed, 'vulnerable', shaky legs, light-headedness and all in all, generally washed out. It has not affected my appetite.		M	62	7 days		7/8/2007
4	SuspectedGiardia	Loss of appetite; lethargy; intermitant stomach and abdominal pains that moved around to different areas of abdomen;	Took 500mg 4 times per day fo 5 days. I would recommend talking to your Doc about taking Tindamax instead for Giardia treatment as it's a one day treatment and basically as effective as Flagyl for Giardia. My appetite was WAY DOWN on this med while taking it. Very strange--as I could tell my body was hungry (rumbling) but had to force food down. Have lost 15lbs!! Am 4th day after finishing Flagyl and still have the bad taste of med in my mouth after eating/drinking and appetite is still down. Back to my job, but completely tired when I get home, albeit I think i'm slowly improving. Taking powerful probiotic supplement to ward off reinfection(s) og Giardia or candida (yeast).Good luck to all.	M	48	5 days		8/22/2007
4	diverticulitus	Horrible horrible taste. The taste stays in my throat regardless of what I tried to wash it down. Causes mental confusion, occasional episodes of extreme diving type of depression, which would clear up after a few minutes - but constantly repeats.	I've been prescribed metronidazole before. Never could finish the full course. First time I was quite scared of the diverticultis, and managed to get to like 6 days before I had to quit. This time, I only made it to 3 days. I have to stop, now. I'd almost rather die than continue taking this poison. Its listed as a carcinogen. The Cipro I can do the full course though.	M	46	3 days		1/19/2007
4	Infected Diverticula	This is in response to the above post from me earlier. It took 5 WEEKS from the day I stopped taking the drug until all the depression side effects were under control. I still feel some of the effects every so often but that 5 weeks was pretty awful. You have good days which feel almost normal and bad days where you feel like you can't get the depression out of your head.	I suggest drinking plenty of water AND getting outside in the sun for a few minutes each day. That seemed to help. Also I tried taking some St. John's Wort and it seemed to worsen my symptoms plus it says it takes 2-8 weeks until the effects are felt so it could have been I hadn't been taking it long enough. The metronidazole did clear my infection but with a heavy price. ALSO I had thrush (tongue fungus) as a result from this and you should always take acidopholus to help the good bacteria regain a foothold in your body. It will also help clear up the thrush.	M	27	10 days		7/20/2006
4	Diverticulitus	This is as close to insanity as you will get! Dont worry - its not you. The good old you is still in there, this drug makes you believe your nuts. And you will act nuts too, youll start to do something then youll do something else.. everything tastes like sh*t and it totally sucks, BUT if you have life threatening circumstances, then take it because this drug might kill it. I know it sure felt like it was killing me.	Reminds me of Hole's first album: "Live through This"	M	48	3 days		11/24/2006
4	Trench Mouth/Kidney infection	Salty, metalic taste in mouth. I drink lots of fluids just to get rid of it. It also changes the way food tastes. I've only been on it for 1 day...I found this website while looking to see if this horrible taste is from the meds..I will stick it out as I was feeling terrible yesterday and I want to get better. I feel somewhat better already so I hope it works...		M	51	1 days		6/30/2006
4	Root canal treatment	Other than dark urine and feeling a little vague; no problems.	The advice to avoid alcohol includes 48 hours after finishing the course of treatment.	M	58	5 days		3/11/2007
4	Intestinal Infection	A little wishy-washy feeling, bad taste in my mouth, food (mostly liquids) taste weird, maybe vision a little blurry.	Taking with Cipro to address some kind of NASTY colitis-type thing. 500mg 3x/day. Seems to be working. I'm feeling better. Worst part is the taste of the pills. I just can't slug the pill down fast enough. The taste is actually so horrible it brings tears to my eyes. Will try the "coat it in maple syrup" thing next dose. But overall, given that 3 days ago I thought I was dying, I'm happy with this med.	M	46	3 days		2/25/2007
4	Tooth abcess infection	Almost constant stomach upset and sometimes pain, general feeling of malaise, irritable, anxiety and depression, some diarrhea. But the stomach upset was the worst--I had to force myself to take this drug through the cycle. It was a real battle.	As much as I hated taking the drug, I found that it works well to decrease swelling that results from infection. I've taken it twice now, and the only way I will again is if there are no other options.	M	28	7 days		12/14/2005
4	stomach infection	Light-headed, dizzy at times, constant feeling of nausea,loose and very dark stool, loss of appetite; Taken with Cipro because blood work didn't indicate anything else and Doc was convinced it was bacterial	Due to diagnosis (or lack of), difficult to determine if side effects resulted from possible infection or meds. Just Finished!	M	37	7 days		10/7/2005 Email
4	dental infection	like a lot of posters here i just felt really, really, really wierd whilst on this medication. If the pain from the dental infection (I am a man and not able to stand tooth pain at all) was not so severe I would have stopped the medication. My only reason for carrying on was if it made me feel that shitty it must be working. I pretty much got the full monty of side effects including such a pronounced swelling of the lower face and lips that I had a bigger overbite than homer simpson. Still my daughter thought I looked funny with a head like a football. Urine very orange and not forthcoming. Kidneys turned to concrete and I swera I could feel this shit altering my DNA. As someone else posted - as close as you can get to insanity - any I didn't have any depression or similar episodes. Well worth avoiding - Where's my whiskey?	see above - had to slow medication down to 2 meds a day (from 3) half way through just to get through the course.	M	42	5 days		12/7/2006 Email
4	Perianal Abscess	Nothing that noticeable.	worst tasting pill I ever took. Tic Tac after the pill removes the chalky taste. First good night of sleep in over a week. Woke up with little pain and no blood.	M	39	5 days		5/17/2006
4	GINGINVITIS	Metallic taste in mouth but by far the worse was the feelings of confusion and depression. Felt my head was going to explode and on the verge of breakdown in tears for no reason all the time but did clear up the gingivitis.	I will be asking my dentist for an alternative if required to take further medication.	M	38	7 days		11/8/2005 Email
4	Wisdom tooth pains	nasty side effects - constipation, upset stomach, cramps, severe bloating, depression, aggressive behaviour, dizziness, spaced out, lethargy.	It might ruin your week and is hard to take the full packet	M	23	7 days		3/3/2006
4	Perianal Abscess	Nothing that noticeable.	worst tasting pill I ever took. Tic Tac after the pill removes the chalky taste. First good night of sleep in over a week. Woke up with little pain and no blood.	M	39	5 days		5/17/2006
4	Parasitic Infection	I'm so glad I found this site. I was so concerned about the acute physcosis I experienced on this drug. I was prescribed and at first noticed a detached feeling a few hours after the first pill. By day 3, I was seriously thinking I was going crazy. I had severe anxiety, disturbing dreams and a general nervousness that these symptoms were not going to go away.	I was just told by the doc that I may need to stay on this drug for an additional length of time. This web site has really calmed me down knowing that this is a much more common side affect than expected. Thank you all for being so honest about your side affects.	M	37	7 days		9/17/2007 Email
4	Ear infection	Sweating, fever, shivers, nausea, fatigue, odd sleeping patterns i.e. asleep by 9pm, awake at 5am - very unusual for me. Do not like it. Prescribed this drug for a toothache at Christmas but chose not to take it due to worry over effects. Desperation has caused me to use it for inflamed inner ear and severe pain. Taking with paracetamol and ibuprofen.	Scary but effective	M	40	7 days		8/4/2006
4	fistula	Drowsniness, strange dreams and a little melancholia.	Metronidazole is a doddle. The side-effects in my case were greatly outweighed by the benefits. I don't think I knew how ill I had been for so long until I took this drug. Pain that I'd got used to living with was no longer there.	M	45	7 days 400 3X D		7/11/2010
4		Taking it for gum infection. Severe headache.	Got the headaches an hour after taking a pill. Will complete the dose to get rid of the gum/toothache but will ask the doctor to prescribe something else if I ever get a similar problem.	M	57	5 days 3X D		6/6/2010
4	diverticulitis	Not many side affects just a metalic taste in my mouth about 5 days into it.I am taking 500mg of metronidazole 3 times a day and 500mg of ciprofloxacin hcl twice a day for 10 days. Both have worked pretty good for me being most people have said these are the two worst anitibiotics known to man. Take your meds people doctors know what there talking about chances are if you are reading these comments you have never been to med. school.	Take your meds. live life and be happy if there bothering you call your doctor and get different kind.	M	29	10 days		1/29/2010
4	BV	Metallic taste in mouth, loose stools, foul smelling & dark urine, milky white discharge in vagina,unmotivated, appetite is up and down	I'm on day 4. i think it's working, but i can't really tell since i have this discharge and smelly pee now. the taste in my mouth SUCKS. it's nasty, but not unbearable	M	21	7 days 500 mg 2X D		4/6/2010
4	stomach infection	Took two pills daily and by the 2nd day was experiencing extreme lethargy. Wasn't motivated, lack of energy, could lay in bed and stare at my ceiling for hours. Sunny days seemed like rainy days. Felt like the world was ending. By the 4th night i couldn't sleep and my heart was racing so i stopped for 2 days then started again.	It's a foul tasting pill, but i took it with orange juice so the odor was nonexistant.	M	22	4 days 500mg 2X D		4/10/2010
3	Bacterial Infection	change in stool color, metallic taste, white tongue, sore throat (one side of my throat)	I fist used this 200mg 3x 10 days. After I stopped the medicine my throat was fine and white patches disappeared. Then I had to start again, 500 mg 3x 10 days. All side effects appeared again, 3 days to go. I also feel very moody, hungry and not hungry at the same time, have the metallic taste for 3-4 days but gone now.	M	30	10 days 500 mg 3X D		3/8/2010
3	bacterial infection	severe nausea, metallic taste in the mouth, lethargy, sleepiness, light-headed, irritability, headaches, depression	The side effects of this drug are pretty terrible. I don't know if it's worked yet as I am in the middle of taking my prescribed dose, but I have had a really miserable experience. I have experienced extreme nausea throughout and a pretty bad metallic taste in my mouth. Depression, lethargy are constant and I have no appetite. I am now on my fifth day and the nausea is abating a bit. Better than what it was before but still pretty bad.	M	48	7 days 500 mg 4X D		6/2/2010
3	dysentry			M	38	800mg 1X D		5/16/2010 Email History
3		cramping and bloating, jumping heart, feel bad, stomach growling, acid in stomach, dark urine, head ache, diarrhea, feeling of distress	I am taking this with Amoxicillin. This is certainly unpleasant but not as bad as the pain from my sinus infection caused by wisdom tooth removal. I am staying close to the bathroom. I am half way through the 10 days and I am counting every pill – waiting for the end. I will be glad when this is over.	M	64	10 days 500 3X D		7/16/2010
3	Gum Infection	Feeling low, fatiuge, dry mouth, thumping headache	Took 5 days to start working on gum infection. Feeling realy low seems to have been the worst side effect	M	44	7 days 400mg 4X D		6/27/2010
3	Intestine infection, Diverticulitis	Dreadful, furry tongue, brown urine, hang over feeling, shaking of hands and arms. cloudy head all day, tiredness, weakness in legs,dizziness, lack of concentration, Endured just, but would never use again. They were taken with Klaricid tablets, just as awful. Positive is that intestine infection cleared up.		M	63	5 days 400 3X D		7/22/2010
3	Tooth Infection	Depressed, tired, irratable, finding fault with everything, not sleeping well, cant concentrate, distort, cant balance, slight tingle in legs.	Infection without knowing about it, discovered by my dentist when going for checkup, had slight sensitivity to hot and cold drinks now nothing. Seems to be working but very down and depressed, not like me.	M	21	4 days 400mg 3X D		8/5/2010
3	Intestinal infection	Numbness (while sleeping), slight nausea, occasional tingling, slight headache and loss of appetite.	My condition improved but the side effects were troubling. The tingling and numbness in the extremities mainly at night and began shortly after I started the drug. The effects started in the two smaller fingers then up my arms to the elbow. The effects continued to my lower left foot with tingling and numbness days later. The numbness would subside after I awoke, but a slight tingling or burning sensation would continue after. The other symptoms were mild enough I found to be brought on if I did not eat and subsided after having food.	M	36	7 days		11/23/2005 Email
3	Diarrhea (Giardia suspected)	Severe headache and dizziness for the first 2 days. It has now been a full 7 days after taking the medicine, and I still have furry tongue and severe stomach pain with nausea. Still waiting to feel better. My loose bowel movements have gone away, however.	Don't know if the side effects were worth taking the medicine for 7 days. My furry tongue is nasty. Nothing tastes the same- especially diet sodas. My doctor tells me it should go away. Still waiting for that to happen. Getting worried. If anyone else has my lingering symptoms, please email me! Put my mind at ease...	M	42	7 days		12/2/2005 Email
3	Possible giardia infection	Depression, irritability, nausea, exhausted and tired, terrible loss of appetite, white furry tongue, brown urine, anxiety, a feeling of detachment and estrangement from others, as if there were an invisible wall between myself and the world	I was relieved to read these other posts. Now I only hope that these side effects wear off soon after I finish the medication. It is the worst drug I have yet taken, but the terrible gas from giardia has gone and the diahrrea is fading away as well. Possibly the worst two side effects are the loss of appetite, which makes the mere thought of food nauseating, and depression. Like most others I was unaware of what I was getting into when I began taking this medication.	M	23	14 days 500 mg 3X D		8/28/2010 Email
3	Giardia	Lightheaded, dizzy, tired, foggy, headaches. It was difficult to sleep all the way through the night.	I just finished a five-day course of Flagyl and I'm praying it cleared me of the Giardia. I still feel as if I'm on the Flagyl and still feel foggy, but not quite as tired.	M	41	5 days 250mg 3X D		9/1/2010 Email
3	?grumbling appendix	see previous posting ?grumbling appendix -not sure this Dx is correct The rationale was that this Ab would kill bacteria in the appx before it kicks off to appedicitis.	in addition by day 4 Loss of appetite Some nausea I'd dearly love to stop this but this is typical of some Ab's -the side effects are so bad you stop them .The bacteria arent all destroyed so some survive and are stronger and more resistant.Don't think this Ab will be around long as patients cant tolerate it.	M	43	7 days		10/22/2006
3	diahrrea (suspected giardia)	nausea, dizzy, lack of energy, bad taste in mouth, extreme bloating. Do not drink alcohol while taking this medication. 500mg 3x per day.		M	25	7 days		5/14/2006
3	C. Difficile Colitis	This is my second course of metronidazole for C. Diff. The first course was 250mg po x3 for 10 days. It didn't resolve my colitis, but did lessen the symptoms somewhat. This course is 500mg po x3 for 14 days. Today is Day 8. The most noteable side effect duirng the first course was the metallic taste in my mouth, which I also have this time. The side effects during this course are truly scaring me though: Extreme fatigue, lack of appetite, dizziness, lack of coordination, nausea, pressure and bloating in my stomache, and general weakness. I'm also having some emotional swings, which I'm not sure are a direct effect or secondary to my generally ill state. Luckily I have these few weeks away from work. Otherwise, I'm not sure how I would function. Reading the other posts, I realize I'm not alone, which leaves me unsure whether to contact my internist. Truthfully though, I'm not sure I can last another 6 1/2 days on this drug.		M	38	14 days		8/30/2006
3	Giardiasis	From day one (400mg 3 times a day) aching joints, tightness in the abdomen area, pressure and pain when move the eyes, hot sweats at night, interminable puzzle dreams. Occasional reduction in hearing capability, headaches like I've had a hangover.	Worked a treat on the problem - characterised with diarhoea, lots of awful gas and stomach cramp. But head pains very unpleasant. Will see it through but would have much preferred something else. This is the first time I have had problems with antibioitics.	M	37	7 days		4/22/2007
3	Dental Abscess	Nausea, loose stools, morbid depression, exhaustion	Actually felt suicidal a couple of times. It killed the infection where amoxicyllyn couldn't but I have never felt so low or useless. If at all possible investigate an alternative.	M	47	7 days		3/18/2007 Email
3	Yes	After about 3 days of taking the pills, I would feel really dizzy, hard to concentrate. This side effect made it hard for me to sleep. Also, one night I had a weird experience that I guess you could call a panic attack. I've never had one before, so not sure what to compare it to.	Other than the pycho side effects, it served its purpose of taking away my bacterial infection.	M	30	7 days		10/11/2007
3	Gum Infection / Bleeding	On metronidazole for a week. No side effects for first two days then extreme tiredness - thank god I was off work for the week.	Tablets taste disgusting! Have a strong flavoured drink to wash them down - not jsut water!	M	25	7 days		12/1/2006
3	c-diff	nausea, vertigo, extreme anxiety, extreme depression, fatigue, gas, loss of appetite	The symptoms of c-diff went away after a few days which was great. Than a few days later the side effects kicked in. My depression got so bad that I had trouble getting out of bed, and I didn't want to go anywhere under any circumstances. I'm normally a very sociable person, so this had me extremely worried. I also felt like sleeping anytime anyplace. I have been off the medicine for 8 days and the side effects persist. I was so dizzy and nauseus yesterday that I had to leave work. I spent the rest of the night in bed. Today I am so depressed (I don't know why because my life is going well aside from this demon drug) that I don't even want to go to a concert tonight that I paid a fortune for the tickets. I will force myself to go, but I fear that the anxiety will ruin it for me. I've been taking xanax for anxiety for a few years, which always helps. Not anymore. I think I could take five in a day and still have a panic attack. I hope this goes away soon as I would really l	M	28	16 days		10/31/2006 Email
3	1) gum infection 2) wisdom tooth	irritability, aggressive feelings, almost depressed. Amazingly sharp onset within 30 mins of taking them but seems to go after about 3 hrs.	3 x 200mg per day on two occasions. I suppose it did work the first time against a painful infection but 2nd time was just-in-case after tooth extraction	M	43	7 days		11/2/2004
3	colitis	Strong lower back ache, dizzyness, lack of energy, stomack bloating and mild cramps. There seems to be a two day delay in the side effects of this drug ie they start after two days and last two days after you start. Would not reccommend this drug for minor problems.. took 500mg 3x day; complained to the doctor after the 4th day..reduced to 250mg for last three days.	It is stupid for this site to reguire a RATING of this drug. I am NOT a medical doctor and it's effectiveness in achieving the cure is not the topic here. I really don,t know; therefore I am giving it an average rating since you do not allow a place to decline such an answer	M	75	7 days		10/28/2007
3	Guirdia	Somewhat akin the hangover from hell without any of the pleasures of obtaining it. Feeling thouroughly washed out and generally woozy. I was warned!		M	45	10 days		8/31/2007
3	Tooth Infection	Anxiety, depressive state, unmotivated, clouded thought, darkened urine, diarrhoea & loss of interest in hobbies.	I was perscribed 400mg three times a day. The drug does work as it did get rid of my tooth infection and also some patches of dermitits on my body have reduced. But. First day I noticed my urine darken and had a diarrhoea. After the third day I woke up feeling anxious about everything. I may not carry on taking the drug due to the mental state it gives after a while.	M	28	3 days		11/5/2008
3	Bone infection after root canal	Absolutely terrible feeling of depresssion - have never been depressed in my life. Convinced that the infection was spreading and going to kill me. Very very tired. Spaced out. Felt like someone else. Took with strong Amoxycillin. Only 10 to go. Hope the infection goes		M	36	7 days		9/15/2007
