| 2 | periodontal abscess | tiredness, dizziness, nausea, difficulty concentrating. | i've been taking it for 3 days and eaten before taking each pill and haven't drank any alcohol. the side effects are pretty bad especially the nausea but seems to be working well on my abscess. | M | 26 | 5 days 400 3X D | 4/25/2010 | 1 | bv | Also, I do not drink alcohol and I read the directions. This site is to help other people to know the effects of this drug not to complain. So, whomever made that statement just had no side effects and doesn't realize that everyone is different and our body's will react differently than others to the same drugs. | M | 19 | 500 1X D | 5/13/2010 History | 1 | H Pylori | This drug should be banned. While taking this i have become a different person. Racing heart, constant soft stools, extreme anxiety. I have one more day to go, this drug is scarey, i thought i would die from this pill, and im not joking, it was bad. | M | 55 | 13 days 500mg 2X D | 4/9/2010 | 1 | Dental infection | Prescribed this drug (200mg every eight hours after meals) plus Penicillin (500mg every six hours, at least an hour before meals)…an interesting schedule to maintain on a good day.. ! This was to treat and infection that appeared two weeks after surgery to remove an unerupted (lower) wisdom tooth and excise an attendant vast cist which has significantly damaged the jawbone. Side effects started to appear on second day, and by the fourth day had reached chronic levels - Headache above eyes, general muscular aches throughout body, arthritic-type pains in joints of legs and arms, sharp pain in lower back, stiffness in neck, metallic taste in mouth, dryness in mouth, excessive burping and some acid reflux, nausea accompanying alternating sensations of hunger and appetite loss, dark urine, strong-smelling stools, constant need to (and difficulty to) expel urine, feelings of general disorientation and occasional dizziness, constant tiredness, extreme depression, difficulty in con | I found the site on the beginning of the fifth day, and have decided to not proceed any further with this medication (while I am still continuing with the balance of the course of Penicillin) and will be attending a previously scheduled review session with my surgeon in two days’ time. While I haven’t been to Med School (see post 1/29/2010 below), I think it would be a GOOD IDEA for all Med Students to read these comments in conjunction with everything else they are taught. It is (and has been known for a while!) that one-size-does-not-necessarily-fit-all when it comes to drugs prescribed for the general populace - had I been aware of the effects of this medication at the onset, I probably would have gone looking for something else. I can only hope that my comments may help others come to terms in some way with their situations - just as I have finally been able to do also. Thank you to all who post here! What it HAS taught me, once-and-for-all, is that I will be doing a lot more research about what it prescribed for me BEFORE it ever gets in my mouth. | M | 61 | 4 days 200mg 3X D | 2/6/2010 | 1 | Tooth Abcess | headache, fever type symptoms (hot and cold shivers), aching limbs (especially in hands), no loss of appetite yet blinding headaches after eating, dark urine, stomache pain, dizzyness, balance issues, slurred speach as if I'd had a stroke, moments of temporary paralysis where body completely frozen and only able to move fingers on right hand, complete vacancy as if asleep whilst being wide awake with no memory of events during the episode - went to doctor who on consulting his medical almanac put paralysis/vacancy down to rare recorded cases of epileptic absence. Not epileptic so must be the drug. | Was also prescribed Amoxicillin 500 MG 3 times a day for a week. After starting course of both antibiotics infection quickly improved and pain subsided. On advice from doctor and dentist stopped taking Metronidazole 4 days into course. Am still on Amoxicillin with no appreciable difference except side effects are gradually fading. Can only assume Metronidazole the cause of side effects, but cannot see any treatment benefit from taking it at all. | M | 31 | 7 days 400 MG 3X D | 2/23/2010 | 1 | infection after tooth extractiom | nausia, dizziness, yellow furry tongue, numbness to face, tiredness | tiredness, numbness to face and yellow furry tongue started on 2nd day then nausia and dizziness on 4th..now 24hrs after finishing course all side effects still present and infection hasn't been cleared! back to dentist tomorrow but will not be taking these EVER again! | M | 32 | 5 days 200 3X D | 5/31/2010 | 1 | BV | On day 2 now and having trouble sleeping, metallic tasting film in my mouth and feeling nauseated. Am discontinueing, was already leery of this drug when the warning label said it caused CANCER in lab rats. It is likened to poison. Will try homeopathic solutions. | M | 39 | 500 MG 3X D | 8/19/2010 | 1 | Skin infection | Bloodshot stinging eyes | I stopped taking these after being taken into hospital I get home after stopping meds and my eyes start stinging wether this has anything to do with the lack of sleep I dunno. This is poison for the brain get well soon everyone | M | 30 | 3 days 400 mg 3X D | 7/24/2010 | 1 | wisdom tooth infection | depression / insomnia / really bad mood swings | when coming off this stuff, tooth ache re-appeared. have to wait another 2 days for wisdom tooth to be taken out. feel like strangling the dentist. never ever again will I take this stuff !!! | M | 63 | 5 days 500 3X D | 7/19/2010 | 1 | tooth abcess | given for extreme tooth pain with abcess, day 1 was fine by day 2,OMG dizzy ,faint, nausea constant, could not eat vomiting,unable to even sit up. these are severe symptoms called Dr told to keep going..and I will proberly have to have the tooth out anyway. should have been told about how bad these side effects are.......... have another 5 days God help us. | M | 52 | 2 days 200mg 3X D | 1/11/2011 | 1 | Gingivitis (gum swelling | To the person taking 4 x 500mg/day and feeling awful - STOP and check with your GP - this sounds like overdosing to me - I am a big guy and only on 3 x 200mg/day - it has given me an upset stomach, and I do not like the drug - if it doesn't improve my gums in 2 more days, I will stop taking it | M | 56 | 7 days 200 3X D | 12/24/2010 | 1 | Possible Giardiasis | SEVERE anxiety, nausea, cramping, trouble breathing, mental instability, emotional distress, crying for no reason, depression, tingling in pads of feet and hands, moody, paranoia, fearfull, loss of appetite, some soar throat, lethargic, increased smell, profuse sweating, headache, feeling of impending doom, terrible nightmares, spacey, furry tongue, racing heart, and on and on | I Quit!!!! I have only taken 1 pill a day for the last 3 days and I still experienced every side affect imaginable. I have called my gp every day since I have seen him and all he wants to tell me is to try and come all 3 perscribed pills in a 24 hour period. I have fought with my girlfriend who i live with every day since I started taking this med. Mostly she thinks I am standing in my own way of getting healthy, I still refuse to take this anymore. Yes giardia or whatever I have is no fin but combined with flagyl it is unbearable. Reminds me of zoloft. :( I am getting lab tests done tomorrow to hopefully disprove my diagnosis. I wouldn't even mind taking a less effective med with a shorter list of side effects. Furthermore this seems to be the only medication I have an allergic type reaction too. No rash but shortness of breath and tightness. I absolutely despise this medication!!!!! Hopefully blood test and other nasty lab doings can disprove this diagnosis but either way I done!!!! | M | 22 | 10 days 250 3X D | 12/27/2010 | 1 | Possible Giardiasis | SEVERE anxiety, nausea, cramping, trouble breathing, mental instability, emotional distress, crying for no reason, depression, tingling in pads of feet and hands, moody, paranoia, fearfull, loss of appetite, some soar throat, lethargic, increased smell, profuse sweating, headache, feeling of impending doom, terrible nightmares, spacey, furry tongue, racing heart, and on and on | I Quit!!!!

I had to take 10 x 400mg tablets in one go. Iwas a little nervous about this. I asked about safety and was told it is tolerated at this dose by women with 'ertain conditions' and the main thing is I MUST NOT drink alcohol for at least 24 hours. I had headaches for a day or so and felt a bit woozy. 24 hours later my urine turned REALLY dark. No improvement in my condition. About 2 weeks later noticed weakness in both legs below knees. Random stabbing pains over tops of shins. This leg pain has now persisted for a month. The doc has said the drug would not cause any leg problems even at this dose and has put me on 2 weeks of other antibiotics as NSU still not clearing up. Ive searched all over interenet and not found anyone prescribed 4g in a single dos | M | 41 | 1 days 10 x 400mg 1X D | 2/16/2011 | 1 | can't sleep, depression, can't concentrate | what a horrible drug to have to take, let's hope it works. | M | 31 | 14 days 400 mg 2X D | 11/15/2010 | 1 | Appendicular mass following hospita | EVIL EVIL EVIL! Was given these after spending a week in hospital with an appendicular mass and a week of IV antibiotics - these fuckers are evil. Terrible insomnia, I was begging to sleep but couldnt - stomach cramps and pain, feeling utterly shit, blurred vision. Rang up hospital and told them I could not take anymore. They are the devil incarnate of drugs!!! | M | 40 | 3 days 400mg 3X D | 8/12/2010 | 1 | Precaution after dental work | Headaches, dry mouth, metallic taste, fatigue, dizziness, depressive thoughts, sense of confusion | Following dental work this was prescribed as a precaution against possible infection. I would have MUCH preferred the infection. My thought processes have confused, I have felt depressed and emotionally at a standstill. The headaches have been terrible, at times like my brain was either pounding the inside of my skull or that it was actually sitting outside of my head. Overall an unpleasant sense of otherworldliness. AVOID!! | M | 45 | 4 days 3X D | 11/3/2011 | 1 | Wisdom Tooth Infection | I feel like my gum is pushing my teeth out, no sleep and can't stay still. | Don't take this thing, it's a nightmare. | M | 27 | 2 days 200 3X D | 5/31/2012 | 1 | Tooth treatment | Flu like symptoms, Depression, Extream fatigue, irritated muscles, so tired, but had to move at same time, panic. Felt very ill | Took 3 times over month, last time only took 2 before I realised. I thought I had a bad infection and it was helping me. How wrong. I will not be taking again. 10 days later still having problems. Would like to know if other had lasting side affects? | M | 56 | 7 days 250 3X D | 12/29/2011 | 1 | surgery infected cyst removal | METRONIDAZOLE surgery infected cyst removal allergic reaction to medicine jaundice and rash on top centre forehead brown streak down centre of tongue extreme tiredness on Iv drip pre and post operation, when put on oral version within about 48 hrs of taking pills then pancreatitis and sudden fatigue had to lie down on kitchen floor when tried to rise 15 minutes later could only sit down and walk around on knees so some leg paralysis; after 30 minutes of this situation and managing to eat some food and drink by walking round kitchen on knees then fire alarm went off which gave me shot of adrenaline could then stand up….. stopped taking it would never take it again….. | my brother said also caused him paralysis when given to him abroad , no hesitation ban this monster drug it also causes serrotonin effects not given on leaflst warnings so they are hiding some side effects that are longer term damage | M | 59 | 4 days 500 3X D | 1/3/2012 | 1 | tooth abscess | Within an hour of taking the first tablet I started to feel achey in my leg and arm muscles, a couple of hours after I started to get a migraine, felt dizzy, nauseous and started sweating a lot. After sleeping for 16 hours, still had a slight headache. Took the next tablet later that day and had no noticeable side-effects, only slight sweating. Finished the course, though it didn't do anything to clear up the abscess and felt fine. A few days later started to get anxious thoughts about dying. a week after finishing the course these thoughts still keep coming. I get thoughts that my heart is failing and that i'll die when I go to sleep. They seem completely rational thoughts, and even though I know in reality they are false, they seem so real. I'm hoping these feelings will subside very soon. | I will refuse to take these again if prescribed. They did nothing for what I was taking them for, and the side effects have been too horrible to go through again. | M | 33 | 6 days 400mg 3X D | 1/19/2012 | 1 | Tooth Abscess | Feels like my tummy is actually eating itself. Extremely tired slept for 14 hours never done this in my life before and i am still washed out. Feel not on this planet. | Ive only got to take 9 in total ive taken 2 and wonder if i can carry on. Cant feel the tooth abscess anymore but the other side effects are probably masking that. | M | 28 | 1 days 400 3X D | 2/14/2012 | 1 | swelling in gum | I experienced sore head and tightness of neck initially. After a few days started to feel depressed and anxious which is unlike me. Glad I have read this site. Stopped the meds 2 days ago still have the emotionsl/psychological effects. Can anyone please tell me how long these take to clear? Either professional or personal experience opinion would b appreciated. Horrible drug! | M | 31 | 4 days 200 | 1/21/2012 | 1 | C. Diff | This drug is absolute hell. I had almost every side effect you could imagine...Insomnia, trembling, zero appetite, felt like I was going crazy, severe depression., sudden movements and tremors, nausea, watery BM's. | I dont know what to say about this drug honestly its so bad. I was sick for about 2 months and had every test under the sun done to me. Finally after a 3rd ER visit, C.diff was found in my stool. My doctor thought this was the drug to "try" to rid the infection. I can honestly say this medicine did not cure my c.diff and did not slow down any of my symptoms. I was never having 20 bowel movements a day to begin with. Just maybe 1 or 2 but very loose and light colored. After 11 of 14 days I finally called it quits with this poison. I wasnt significantly getting better and was dealing with way too many side effects. My doctor put me on Vanco which I am on my first day of it right now, and I have to say I already mentally feel like im getting better. DO NOT go on this drug, just get Vancocin its worth every penny if you want to get better. Zero side effects to Vanco thus far. | M | 27 | 12 days 500 3X D | 6/25/2011 | 1 | swollen gums from wisdom tooth | PANIC ATTACKS, hard to breathe, constant worry and stomach upset. | Im coming off this medicine as the panic attacks are too much. | M | 30 | 4 days 400mg 3X D | 6/11/2011 | 1 | E. Hystolitica | This med is terrible... complete desturction to the body. Very unusual effects like disoriented, shortness of breath, not able to stand for more than 2 minutes. This is garbage and not medication! | DO Not try it at all. | M | 47 | 5 days 500 2X D | 8/15/2011 | 1 | C-DIFF | Dry and horrible taste in mouth, loss of appetite, loss of sexual desire, depression, insomnia, palpitations, can't sleep... | Seems to have cleared the infection at least... | M | 25 | 10 days 500mg 3X D | 2/18/2012 | 1 | Diverticulitis | This is a horrible drug. Iwas in the hospital for 4 days and received this thru my IV. I also took it for 2 days after that at home. I developed a severe rash and hives by the third day. During the first two days I was itching everywhere. I have had anxiety problems in the past, but this drug made me feel incredibly weird. I became angry and sad at times and felt like I was going to have a panic attack while in the hospital. I paced the room at night, had cramping, constipation, and bloating. By the the third day my vein collapsed in the IV. They movedte IV 2 more times until I finally told them no more! I told the surgeon many times but he refused to believe that the drug was causing any problems. My family doctor finally was te one who said stop the drug 5 days later. I had to have steroids and take benadryl for 7 days because of the rash and hives. I kept calling my wife while I was in the hospital to come and get me as my anxiety became so bad. Don't take this drug! | i will not take this drug again! | M | 50 | 5 days 500mg 3X D | 6/29/2012 | 1 | gum infection | I had very sore gums , when i took these tabs it just got extremely worse. I had to take 4 paracetamol 500mgs to get rid of it. | M | 58 | 5 days 200 3X D | 9/12/2012 | 1 | amoebic infection E.Hystollitica | nausea, irritable, aggressive, loss of appetite, unable to focus, some weakness in the legs, bitter taste n mouth | The Doctor warned me that this pill will probably make you feel unwell. If the Doc knows this then why does it then have a 'middle' rating. This was my 2nd attempt at eradicating the amoeba. The first attempt was just 500Mg x 3 per day and it didn't work | M | 55 | 10 days 750Mg 3X D | 8/19/2012 | 1 | wisdom tooth extraction | Utterly horrible! Started 24 hours after first dose with numbness in my feet, which then spread to my hands. Bloated 'windy' stomach. Dark and frequent urine.Then on day 3 came the nausia and a tight chested feeling (felt like I was on the verge of a panic attack - very anxious), unable to concentrate. Then came neck pain. After 3 days of this I called my dentist who advised to stop taking the pills. Side effects subsided over the next few days. But 4 days after I stopped taking it, I developed a blistering sore rash on the tops of my hands and lower arms, eyelids and feet. Now taking antihistamines to control the rash. Now 8 days since I stopped taking metronidazole and rash is still present but not quite as aggressive. Hands and feet still tingle but feeling is slowly returning. | Unless you have taken this drug before with no adverse reactions, I'd strongly advise not to take it. Ask your doctor/dentist/pharmacist for an alternative. I'm a healthy, active 29 year old male with no history of allergy or reaction, but this drug has made me feel worse than I have ever felt in my life. If you're suffering from similar side effects you have my sympathy. Don't delay speaking to your doctor if any of these side effects are present. | M | 29 | 5 days 500 3X D | 8/22/2012 | 1 | gum infection,absese | Metal taste cant sleep eat confused,not nice atall will never take again as it burnt my mouth and lip ended up in more pain than when started should be BANNED | M | 38 | 7 days 400 | 1/22/2013 | 1 | tooth ache | stomace ace, head ace, very dark urine | This drug should be scrapped. | M | 60 | 5 days 200 3X D | 5/9/2012 | 1 | Gum infection | Feel like my head is going to explode, metallic taste, drinking 5 litres of water aday to help. Dizziness. loose stools. stomach aches. racing heart. insomnia. | Id rather have the gum infection any day. Taking the drug is more painful. This drug is a joke. There must be somthing else that does the job without these side effects. Giving up on day 2 of 5 day course. | M | 2 days | 8/17/2006 | 1 | intestinal bacteria | fatigue, irritability, restless/sleeplessness, depressed, difficulty concentrating, agitated/jumpy, general malaise, slight headache, cotton mouth, lingering bad taste | I have never been affected by a drug like this. I'd rather drink ipecac - at least I know the effects will eventually go away. The side effects last all the time - they don't get better while taking this stuff. I'm scared to drive, I'm easily distracted, I'm exhausted, but at the same time I've got this awful nervous energy that won't subside so I can't sleep. And this taste... You can't describe it. It's awful. The initial taste is bad enough, but this lingering taste - I can't stand it. And to top it off, it makes you depressed! What bliss! I'm a positive person and I've never just broken into tears, but it takes a lot of effort not to break down and cry. I've been on this prescription for 7 days with three more to go. I assume I'm getting better, but compared to these side effects, I'd rather be sick again. There has to be a less severe alternative. | M | 37 | 7 days | 1/9/2006 | 1 | Anxiety, depression, irritability, irrational behaviour. This drug is the pits! I feel like an unwilling participant in one of Dr Mengler's experiments in Nazi Germany. | If this drug doesn't cure the infection (suspected Giadia) I'm going to shoot my doctor! | M | 34 | 6 days | 1/23/2006 | 1 | blastocystis hominis | Second round of possible parasitic infection. I've had a colonoscopy and will have the upper GI work done this week. Tested positive for Blasto. | I have never felt worse. Taking it with cypro and I feel sick to my stomach, jittery, and very depressed. The horrible taste in my mouth is almost more than I can stand. I am not even sure that it is working. | M | 47 | 4 days | 4/8/2007 | 1 | colitis | After one day started having weird dreams, when I could finally fall asleep. Mild headache 1st day, 2nd day after two doses, headaches were worse. | Would not ever take this medicine again especially after reading others experiences. | M | 36 | 2 days | 10/26/2008 | 1 | Gingivitis | Extreme pressure in head. Felt like my head was about to explode! Mild disorientation. Feverish. Could not think properly. Abstract thoughts. Confused. Irritable. Aggressive feelings. Spaced out. Generally feeling yukky!! Most unpleasant and distressing. | M | 52 | 2 days | 6/10/2004 | 1 | Wisdom tooth extraction | This is scary medicine as on day 1 i experienced shivering and fever,day 2 a massive headache,really bad headache..day 3 was worse i was feeling so so high and like i was not myself,it was scary and i felt my arms and legs going numb and felt like i was getting a STROKE.....i stopped now was meant to take 400mgx3times for 5 days | M | 24 | 3 days | 6/18/2006 | 1 | H Pylori | Confusion, nausea, severe stomach pain, overwhelming fatigue, high blood pressure, loss of motor skills, body shaking, extreme paranoia, appetite loss, tongue coating, feelings of cold and wet, but not really happening. | I believe the Nazis invented this. It's been 4 days off the meds and I'm getting rid of the side effects a little more every day. I thought I would be brave and take them anyway, despite the side effects, and I was foolish to do so. I made it 6 days out of 14 and I'm glad I quit. Very dangerous drug. | M | 34 | 6 days | 1/25/2007 | 1 | infection | WORST MEDICATION EVER | PLEASE REPORT IT TO YOUR NEAREST CHEMIST/PHARMACIST there is no where on the leaflet telling us of our side affects.. PLEASE REPORT IT... | M | 35 | 14 days | 5/20/2007 | 1 | Stomach Ulcer | Complete inability to get on with life. Literally passed out after minutes of taking it. Confusion, disorientation, depression and anxiety attacks. Urine turning dark orange. No problem with sleeping because I wasn't conscious! | I asked my GP to prescribe me with new antibiotics after 3 days. I still feel the effects when I am tired, even though it's been well over two months. Effects remaining are confusion, disorientation and depression. | M | 23 | 7 days | 9/25/2007 | 1 | rash,aches and pains somewhat similar to flu like symptons, everything real cloudy. | could not say if it work or not. But do your own rsearch and ask the Doc if another product could be used!!! | M | 46 | 7 days | 6/18/2007 | 1 | divertivulitis | The usual nausea and metallic taste in mouth, loss of appetite, abdominal cramps etc. Metallic taste, irregular appetite and sensitivity to alcohol lingered a week after drug was discontinued. | When it's used for diverticulitis, a disease causing abdominal cramps, one must realize that the disease may be getting cured, but the symptoms persist, caused by side effects of metronidazole. Without this knowledge, one naturally suspects the diverticulitus is getting worse. The last thing a patient wants is a drug that increases the symptoms of the disease for which they're being treated. | M | 63 | 7 days | 4/14/2005 | 1 | blastocystis hominis | loss of appetite; nasuea; light-headed and dizzy; irritable; terrible stomach pains; brown colored urine | My son was prescribed 750 mg. 3x a day for 10 days. By Day 5 he was out of his mind. He would have a complete breakdown because he felt so sick and he normally is a very happy-go-lucky kid. Not a big complainer. Its definitely not right that the treatment makes you feel more sick than the illness itself! I too am very glad I found this website because it helped us to make the decision to terminate the course immediately especially when I discovered that it is listed as a carcinogen on a website of NJ Health & Senior Services Hazardous Substance Fact Sheets. Day 1 after stopping the medicine he felt normal again. I don't know if it killed the parasites but at this point we don't care. He feels a whole lot better than the side affects from this evil medicine! Will try to find an alternate solution if original symptons return. | M | 12 | 5 days | 2/28/2007 | 1 | Root canal re-treatment | Continuous unpleasent metallic taste after 4th dose; Extreme irritability; Fidgity feeling for several hours after taking it; Very uncomfortable spacey feeling like anxiety without increased heart rate; General feeling of having a toxin in my body | There were no side effects after the first couple of doses but they developed around day 2 and got progressively worse. The side effects became so bad I stopped taking it after 9 doses (2 1/2 days). I will elect to have this tooth extracted rather than stay on this drug if there aren't any other options. I will NEVER take this drug again. | M | 37 | 2.5 days | 3/31/2005 | 1 | PERIODONTAL | DRY MOUTH, DIZZINESS, FELT LIKE A HIPPY ON A TRIP, RASH, ITCHING, IRRITABILITY | THEY ALSO PRESCRIBE THIS TO DOGS AND CATS. SOME SIDE EFFECTS CAN CAUSE DAMAGE...PERMANENT TINGLING TO FINGERS AND FEET. | M | 51 | 1 days | 6/10/2003 | 1 | Tooth Infection | Constant nausia, tiredness, confusion, forgetfullness, dizzyness did I say nausia? In short hangover from hell, it just wont go away! All of these are in equal amounts as well not just waited slightly to dizzyness etc. They are all 100%. Also strange light sensetivity with light being very bright to me. See how forgetfull I am ! I have tried two times to remember to type that I have a rash apeared on my elbow as well and kept forgeting. | This stuff sucks. I just hope it works, I tried penecilin and it didnt :( | M | 31 | 3 days | 2/7/2008 | 1 | ear infection | swelling redness of finger joints, itching, trouble having poo | basically medicine sucks | M | 44 | 2 days | 1/30/2008 | 1 | dental infection | Metalic taste in mouth severe stomach pains on day two, tingling in right hand and depression | this is day 7 and it has not touched the infection. The tooth and gum are just as painful as before I started the course of tablets | M | 50 | 7 days | 12/27/2007 | 1 | abcess wisdom tooth | as others have mentioned plus blurred vision tiredness very short temper confusion and irritable. | this drug made me think i was dying seriously thought about going to see my gp until i looked up this site and found all of us suffering from this toxic waste ive still got 4 days to go | M | 28 | 7 days | 12/19/2008 | 1 | Dental infection after extraction | 1 Shivering as bad as the early stages of a very bad cold. 2 Stomach discomfort. 3 Slightly loose bowels. 4 Vile taste in mouth. 5 Slightly raised pulse rate, 70 instead of 60. This began 4 hours after taking the first 200 mg tablet out of a course of 15. | Clearly some take it with no side-effects but it didn't work for me. One of the most unpleasant medicines I've ever taken. Please, never again. After viewing this site, I queried the prescription with the dentist and with a doctor on Christmas eve. They wouldn't listen. I reported side-effects on Christmas day and on Boxing day an out-of-hours doctor prescribed erythromycin. I've had this once before for an infected tooth and from memory it's OK. | M | 55 | 1 days | 12/26/2008 | 1 | Possible intestine parasite | Near death - Brain fog, head/brain tremor, shortness breath,heart felt like it would come out of chest, felt like spine was being ripped from my head.and much more..... | I thought this was a drug reaction however with further research- this was called a Herx reaction due to a blood bacterial infection....very common for Lyme disease. mine happened on day 4 of taking 500mg 3x/day. | M | 40 | 5 days | 1/4/2009 | 1 | Diverticulosis | Worst thing I've ever taken. Just finished my 10 day perscription along with Cypro. Initially, mild headache/nausea. Later, depression, listlessness, wobbly, head-in-the-clouds, diahrea, bloating and mood swings. Now, the following day after completing my perscription, I can add white tongue to the list. | I'll follow up with the outcome of the diverticulosis. How long should it take for the side effects to wear off? | M | 48 | 10 days | 11/12/2008 | 1 | Prevent Infection in Uterus | Blurred Vision-Sensitivity to light-headache-felt like throat was full and numb when going to sleep. COULD NOT SLEEP. NIGHTMARES. took for 7 days and i still feel the sideeffects. I HATE IT. someone please tell me how long this lasts after done taking it??? | HORRIBLE. HOW LONG WILL SIDE EFFECTS LAST AFTER MEDS ? | M | 17 | 7 days | 1/7/2009 | 1 | infection after tooth extraction | spots on my stomach, acute abdominal pain, sickness. anxiety attacks, spells of disorientation, paranoid and psychotic thoughts. depression and dark thoughts. | worse than a week at Butlin.. well perhaps not that bad!! A truly horrid drug that although producing fast results should never have been prescribed to a recovering depressive. During my appointment he said he couldn't comment on my infection because he wasn't a dentist.. then prescribed 400mg metronidazole ??! Not much of a fucking doctor either; not bothering to read my notes, or give any warning of possible side effects. | M | 33 | 3 days | 7/27/2008 | 1 | Absess and broken wisdom tooth | Pretty much everything that has been mentioned above, including not being able to eat over the last week without vomiting, unable to sleep, stomach cramps, very short temper, server lower back pain. | This should be banned straight away in my opinion, since taking metronidazole I have had numerous visits to the doctors who advised me to stop taking it straight away and today I have had to go for blood tests to see if it has caused possible kidney damage as I have turned a slight shade of yellow. I have also lost roughly 2 stone whilst taking these as they have made me so poorly. | M | 28 | 4 days | 5/28/2008 | 1 | tooth infection | severe stomach cramps, pain on my right side, crippling headaches, metallic taste in my mouth, neck pains and a general feeling of having been poisoned. | This drug should be investigated, i have never felt so bad through taking a medicine, i really wondered what the f**k was happening to me, i was given a 7 day course of 3×400mg tablets, unfortunately i have taken 3 days worth before i found this site. Beware! | M | 3 days | 5/31/2008 |
