 5  Infection after wisdom tooth extrac Slight headache and heartburn After reading everyone's comments, I really didn't want to take these, but the intense pain I had from the wisdom tooth extraction infection got me to take it. I didn't experience anything except for a slight headache and heartburn, which didn't really bother me. Take these tablets they really work and are not as bad as everyone says, everyone is different so experience different things, but these really work and the pain went after 3 days F 32 5 days

 5  BV I experienced, fatigue, the feeling of having to puke and I actually puked on day #3 I had numbess/tingling in arms/legs/hands/feet. The next pain scared be, because I thought I had done something wrong with my neck until reading these reviews. Intense Constipation and diarrhea along with dehydration.

 5  Dental Abscess Furry Teeth!! Constantly after day 5! I was tired, breathless & sick but I was lost in a haze of pain and SO I can't say what this particular drug caused. I was on double dosage for first day and on extra dosage via I.V. also on the third day. Was on Amoxicillin trihydrate 500mg for the same time (3/day, double first day, plus IV third day). This seems to have cleared up my abscess... they are still monitoring it. My abscess was so bad and so sudden that the whole left side of my face swelled from my jaw to my eye within 48 hours and thats while I was on the antobiotics. F 36 8 days

I did get quite bloated and have an unusual amount of wind, but nothing serious!

 5  Giardiasis Bacterial Infection Loading dose I was expected to take x 5 400mg tablets in one go..side effects: Fuzzy head, lethargy, vomiting and retching all day, aches in knees, headaches, dry skin/eyes, dark urine with weird smell, very strange dreams of regression which I have not had for 15 years, not sleeping, nausea on waking, no food or drink for days, no appetite, stomach pains (although these were combined with my infections). Regular dose x 3 400mg over 3 days...no nausea, headaches minimal, sickness minimal (although anti emetics helping), no stomach pains but feel groggy and fuzzy in my head and still weird dreams. I have been taking these with more food and fluid so make sure youre stomach is lined if possible. Initially I was prescribed a 2 gram dose (x5 tablets a night for 3 nights), but my partner (who is a Dr was horrified at that dose for taking whilst at home) told me to take a loading dose of that then split it over the day with anti emetics (I was given Domperidone 10mg x1/2 a day 3 times a day). The loading dose was horrendous and far far too large for me to take (x5 tablets of 400mgs each, thats over 2 whole grams in one go on an empty stomach as I couldnt tolerate food or fluid) and the GP should really have discussed it with me prior to prescribing. I actually had to go back to the GP twice and demand anti emetics and goodness knows why these muppets didnt prescribe prophylactic Abx for me until this was diagnosed. Fortunately for me I didnt vomit this loading dose out and waste the medication. The anti emetic seriously helped alongside this once the severe nausea settled. I was house bound for ten days on this alongside my infection anyway. Im just fortunate my partner is a Dr and he is mailing my GP to discuss this with him. Im now on x 5 tablets of 400mg split over a day with anti emetics and now Im tolerating food/fluid, Metronidazole actually isnt that bad if taken with food, its doable, but as a nurse, Ive never said to anyone take this Med on and empty stomach as its highly irritant to the gut lining unless its enteric coated. This Med is actually ok, I dont know why ppl keep putting it down, its effective, strong and works. The only reason its coming accross a F 42 5 days

I had only the 2 minor side effects listed and coated the pill with peanut butter to disguise the taste of it. Worked pretty well, but did wake up in mornings with a little bad taste in mouth.

 5   More tired than usual (although this could be put down to other factors), headache that lasted all night on night 3, bit of dry mouth and by about day 4/5 started to notice an unpleasant taste which I managed to mask with coffee and food!! Overall I had no unpleasant side effects. I made sure I took the tablet (one twice a day) after food and with a full glass of milk to get rid of the taste. I also took at the same time each day. I must say I was rather wary of this drug after reading everything on line but I took my last tablet yesterday and have been fine. I also have not touched a drop of alcohol, even though I had some exam results and a bank holiday during the course!! Not sure if BV has cleared as no obvious symptoms.but I will def be looking for any minor changes now!!! All I can say is if u have really unpleasant side effects, see your GP. As I say, I was ok so perhaps its different in different people. F 28 7 days

 5  pelvic infection dizzy, nauseous, insomnia, emotional, heart palpitations, constipation, drained/exhausted. i was so dizzy i could barely walk but i thought it was just because i was on two types of antibiotics and both said may cause dizziness, people had to take my kids to school for me because all i could do was lie in bed. i was a total mess for nearly the whole 5 days i took them, on the last day i went out for dinner because i felt a bit better, had a nice meal with a brandy sauce. i didnt even think, threw up for an hour and a half. its been two weeks since i have stopped taking it and thought the infection is gone i am still having problems if i have a drink with heart palpitations, stomach problems and sleeping and just generally not feeling right. i thought it might be my other medication but have been it it for a long time and no probs, so very pleased i found this site. hope the effects wear off soon.

 5  pericoronitis,abcess, throat infec Tiredness, irritable, unable to focus/fuzzy headed, aching legs, dark urine. This is the 2nd time I've taken Met. The side-effects this time have been less extreme than in 2009. The pain I experience when my wisdom tooth plays up is horrendous - to the point I can't open my mouth and swallowing made my head pound and feel sick - so the side effects were/are nothing in comparison.

 5  Gum infection None. This seemed to work wonders. I had an infection around my wisdom tooth and could hardly open my mouth to fit a spoon between my teeth to eat cereal. My face was swollen and I couldn't talk properly. After a few days it got better and by the end of the course I was back to normal. Then the tooth was extracted.

 5  BV Was more tired than usual but apart from that none at all After I read most of the comments on this site, I was soooo nervous about taking this anti-biotic but I was absolutely fine. Was more tired than usual but slept really well. I drank loads of water when I took the tablet and continued to drink water throughout the day. Plus it says a lot about no alcahol too so I never used mouthwash after I brushed my teeth as that contains alcahol as does other products like body lotion so I stayed clear of usuing them for the 7 days. So the best advice would be to drink loads of water and hopefully you'l be fine :)) F 40 7 days

 5  Vaginitis Constant headaches, white tongue, metallic taste, loss of appetite, diarrhea - overall not feeling well It has been difficult taking this medicine twice a day for 14 days. The metallic taste is the worst part of it along with the white tongue. I find myself constantly brushing my teeth and chewing gum. Doing these things is only a temporary solution.It is taking care of the problem I had; however, the side effects are difficult to deal with for a long period of time. I will inquire about alternative treatment in the future. F 46 13 days

So full marks for that. But my sense of smell seems greatly enhanced. Suddenly realised all my sweaters needed washing; cheddar cheese smelt of truffles, magazines smelt of hot electrical equipment.

 5  Bowel infection Metallic taste, headache, some bloating, nausea, lethargy. Hard to know if bloating and nausea & lethargy are from meds or from recovery from the infection that caused such a gruesome night of pain! Drinking LOTS of water (12 oz. 5-6 times/day in addition to other fluids) and eating small amounts of bland food through the day helps. PLEASE read the drug information you were given. Many are ignoring side effects that the insert says require an immediate call to your doctor! Not all drugs work for all people and they do come with side effects but I am very thankful; the 2 antibiotics I was given are clearly beating the infection. I know because I can stand up, walk and LIVE without excruciating pain! Glad I didn't read this page early on - would have scared me. F 54 7 days

 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

 5  Diverticulitis nausea; loss of appetite; tiredness; headache; weakness Someone below said that this drug kills good bacteria and probiotics should be taken. This is simply untrue; the drug is only taken up by anaerobes (bacteria that do not need oxygen) and this does not include "good" bacteria or those bacteria you find in probiotics. I find the drugs side-effects unpleasant and debilitating but compared to the pain and potential lethal complications of the illness it is treating it is something I am happy to put up with.

 5  Tooth abscess None I have been taking this drug for 3 days and, other than feeling a little sleepier than usual in the afternoons, I have had no side effects all. Having read a couple of articles challenging the theory that this drug creates a violent reaction when taken with alcohol, last night I decided to risk it and had a couple of glasses of wine. I sat back and waited for something to happen - sickness, headeache etc - but.. nothing. I felt absolutely fine, had a good night's sleep and am at work today feeling very well. In 3 days, the infection seems to have cleared and I've gone from having excruciating pain to having none.

 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

 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

 5  Gum Infection This is the first time I have taken this anti biotic which was prescribed by my dentist. No side effects were mentioned when he gave me the prescription and nothing mentioned at pharmacy. I am taking 3 x 400mg per day for 5 days. Day 1 - Chalky taste in mouth Day 2 - Metallic taste in mouth which doesnt go away. Almost like sucking on a 2p piece. Very dark urine Day 3 Dark urine, metallic taste in mouth, depressed, teary. Day 4 - Metallic taste in mouth, dark urine, tearful, confused/foggy and diziness, nausea Day 5 Furry mouth, dark urine, nausea, dizziness/confused, loose stools I have two tablets left to take thank god! My advice would be to take with food - drink plenty of fluids and remember the side effects wont last forever. Rather short term pain for long term gain. F 39 5 days
