 4  BV horrible sick to my stomach feeling, bad headaches, extremely tired and hard time waking up. with my sleep i had frightening and bizarre dreams. one of the last nights on it i couldnt fall asleep and had a severe mood swing. barely had an appetite with nasty metallic taste in my mouth. now that im done, i think i am having heart and back pains in my spine because of it. i think my eye sight might have got worse as well, or just made my eyes irritated. i also have a yeast infection. this medicine definetely took the smell away which i am happy about, but it was scary to take. i was too afraid to drink alcohol and i wouldnt advise doing so. its a very intense medication.

 3  C - difficile bacterial infection Headache from dehydration, diarrhea (it's supposed to fix that D:), severe nausea, severe fatigue (lathargic), tiredness, extreme dizziness, and I am constantly feeling as if I am going to vomit or pass out. Like I worry I am going to black out. 4 days on this stuff so far and it helps one day, and the next it's as if nothings changed. I am taking it as directed on a regular enough schedule for it to be consistant. I'm also taking other medication and because of the bacteria I feel I'm not absorbing it correctly because it's less effective. F 25

 1  Infection in my gums I'm having constant headaches with ear ache and neck pain, I feel depressed and want to cry all the time. Symptoms of a cold with red runny eyes. Hot sweats, tired all the time. Also feel like I'm in a daze, dreamy, drunk feeling and clumsy. I've broken so many glasses in just a few days as my judgement was out when aiming for the kitchen side and I've missed. Not a nice medicine, I was feeling well in myself before taking this medicine. I suffer with migrain headaches sometimes and this medicine has really made me feel bad contantly and raised my blood pressure. I have 5 tablets left and have been counting down the days and telling myself I can get through it, I have been taken of penacilin for the same reason and was told this was better. F 35 5 days

 3  Wisdom tooth infection Metallic taste in mouth, EXTREME TIREDNESS, unable to get up in morning, bouts of hunger and nausea (but no actual throwing up; nausea at bearable level), slightly racing heart, constantly thirsty, weakness, inability to concentrate, slurred speech, mild insomnia. Excellent at killing a huge infection which had spread overnight down my throat and into my gland under the neck. I was in extreme pain and this handled it within 48 hours, so I'm not complaining. Lucky I work from home and had no work, as there's no way I would have been able to function on it. The seventh day (last day of treatment) was not too bad, but the day AFTER that horrendous - feel like I'd been drugged heavily, never been so tired in my life. I took the tablets exactly as indicated. Found dairy (esp. ice cream) and chocolate helpful during bouts of nausea. Hope side effects go away quickly. Was pleased to see that it didn't interfere to any marked extent with my gut flora (which broad-spectrum antibiotics had done a good job of totally wiping out some years previously), so that was a major plus, but hope I never have to take antibiotics of any description ever again! Still, considering the extent of the infection and how quickly it had spread, it was the lesser of the two evils... F 33 7 days

Today is my 5th and final day on this medication thank God! I have been so down the past few days for new reason and had a hunch it could be this medication, I looked up side effects and realized I wasn't alone. I've been feeling very lethargic with no motivation to do anything, but then last night (4th nights on meds) I was wide awake until 430am. This medication is poison! F 27 5 days

 4  BV Loose stools, nausea, vomitting, stomach pain, lethargy, funny taste in my mouth, dark urine, irritability, severe headache This is not my first time taking this medication, I always get the same side effects and I eat a meal before I take it and drink lots of fluids while I am on it and I dont drink alchohol at all to begin with. I suppose some of the lethargy and irratability are from the GI side effects so I try to stay hydrated as well. It beats the alternative of keeping the infection it was prescribed for. When you take this medication avoid any food or beverage that will metabolize into the same chemical as alchohol, you may have to do some research but it helps with some of the common side effects. (That was told to me by a pharmacist years ago.) F 29 7 days

 1  infection after wisdom tooth Very bad indigestion after day 1. After day 2 bad stomach pain and nausea. Horrible metallic taste all the time and blood-like taste now and it's day 4. Tooth infection no better and cheek and gum still feels fuzzy and a bit numb. Have had 2 courses of Amoxicillin already so was hoping this would cure it but no!! Reading all the other comments makes me feel better because I now realise I've been feeling quite down and hungry. Disappointing - hasn't cured my wisdom tooth infection. Guess its a 4th trip to the dentist!!! Tastes horrible.

 1  tooth infection felt dizzy,tingling front of legs, back of hands, panic attacks, night sweats, tiredness, headache, and brain fog. took 9 tablets in June 2008 and discovered later that I had previously been prescribed courses of this medication 9 times over 10 years for diviticulitus as a result this last treatment affected me very much, my GP was very helpful and after medical tests I am now left with reactive hypoglycemia, so no sugar and eat regularly and the tingling sensations are still there. I am not diabetic. Anyone else who has long term problems because of this drug please contact me so we can band together to get a full investigation about what is causing such serious side effects. I understand it is a valuable antibiotic but perhaps it should not be prescribed too many times to patients. F 73 3 days

 1  BV headache,nausea,body temperature fluctuations(chills), irritability,depression,ANXIETY,nightmares, Mood swings with crying,intestinal cramping,loss of appetite, depersonalization,dizzy,numbness, lowered sex drive I've been taking this medication for 3 days and began experiencing side effects the first day. I've barely done anything the last 3 days, haven't been into work because side effects so rotten. My relationship with my live-in boyfriend is being severely affected to the point that he is staying at a friends tonight to give us some space because of the yelling and crying and picking fights.I've woken up afraid every morning since taking this drug, the nightmares are unlike anything i've ever experienced,I'm tired and wired at the same time.Self deprecating thoughts,sensitivity to rejection or perceived rejection. I'm so upset that my doctor didn't suggest another method of treatment when I asked if this was the only med available. He didn't offer the Gel, which I've read in other comments. I WOULD ALSO LIKE TO MAKE CLEAR THAT I HAVE NOT CONSUMED ALCOHOL since starting this medication, in fact up to 2 days before I had not had any alcoholic beverage. I WANT MY LIFE BACK, my boyfriend doesn't deserve to be adversely affected because of what im on, i've never reacted so strongly to a medication before. This is such bullshit! F 24 3 days

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.

 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

I've been emotional about nothing and way overreacting and crying for no reason. This drug is giving me severe brain fog and weird dark feelings like I'm not myself. My depression is overwhelming and I feel hopeless. It has zapped all my energy. I feel faint and dizzy and hot all the time now but I have the chills inside. So weird. Since I have started it I have had diahrrea too. How can this medication be good? It feels like poison. Surely there is a better way out there to get well. I am miserable and I still have a week to go on it. Are we all just stupid? I'm looking on the internet for a natural cure for H. Pylori bacteria in my stomach. F 53 14 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.

 1  Diverticulitis Metallic taste in mouth, nausea, no vomiting but I felt close many times. Chills, cramps, diarrhea, low energy and short temper. Dark urine and fatigue(slept 10-12 hrs/day, although not always in sequence; I took naps because of sapped energy). Was very curt with those around me. I am generally easy going. Aversion to alcohol and food in general tasted different due to constant bad/metallic taste in my mouth. Horrible tasting drug! I was so glad to read some of the other comments. I am taking this medication for a painful abdominal condition and I continued to have cramping and bloating while taking the medication. It was confusing because I wasn't sure if I was getting any better or not until I researched the medication and realized what I was feeling was a side effect of the medicine. So I get prescribed a medicine that gives me similar effects to the disorder I am trying to treat, GREAT. I took almost all of my Rx, I just through the last one away after reading about it on several sites online. I can't imagine missing one pill is going to make that big of a difference. I have looked forward to getting off of this med since I started it. I have barely been able to eat much of anything while on it. I have primarily been on a liquid diet. I ate a lot of soup and juices to try and keep myself hydrated and make sure I got proper nutrition. This was NOT an easy regimen to follow. I drank as much water as I could without feeling nauseous and nothing would get rid of the bad mouth or make me feel generally hydrated. F 38 10 days

I hate being on this drug. Never had any infection or had to take any prescribed drugs that made me feel this way!

The day after I finished the course I felt fantastic and full of energy, it was strange because I hadn't realised it was those antibiotics I thought I was getting the flu. They did work although my mouth is still abit sore but thinking about it now, they caused drowsiness, tiredness, dark urine and I felt VERY run down.

 4  Wisdom tooth/ Gum infection first two days i had no side effects at all, then i noticed my urine becoming very dark like cola, i felt down and emotional, i was nauseous and had no apetite, my concentration was very poor to the point where i was getting frustrated with myself, i felt slightly dizzy, i itched all over but only had a small rash on my leg (3 white lumps most likely hives), i felt tired, 3 days after taking i have developed a sweet taste in my mouth i dont know if its related to this drug. even though it sounds like i had alot of symptoms, it didnt feel too bad at the time, the worst was nausea but it only lasted a day or so (i think it was just the antibiotic kicking in) and my bad gum which had given me the worst pain in my life (rendering me unable to eat and barely drink) started to decrease in swelling and pain within 2 days, well worth persevering with this medication.

 1  Suspected Giardia - wrong diagnosis Symptoms: chills, naseau, hives, migraine, depersonalization (brain fog) dizzyness, anxiety, panic attacks, weakness, possibly made my hypoglycemia worse, sweating, lethargy, hearing loss at times, jitteryness, itchy skin and puffy face, coated tongue, bad breath, mouth sores, redness of the skin, possible enhanced bruising. Probably because I was given this drug and didn't really have Giardia (tests confirmed this later) I think it killed all the good (and bad) bacteria in my digestive system - I should have been told to be on a probiotic when on this drug, but I wasn't. Note: I was given this drug on March 18, 2009 and I am still experiencing side-affects over 13 months later. Make sure you definitely need this drug before taking it! F 27 2 days

 4  Ulcerative Colitis metallic taste, irritability, depression, dark urine and stools at times. Had diarrhea when started the flagyl but subsided after the first week so I think the parasite has been destroyed.I've taken flagyl before and suffered extreme nausea however , this time I had no nausea at all because I added extra carbohydrate to my meal before taking each pill. On previous occasions when nausea was present I ate too lightly. Also, the pharmacist advised me to take a probiotic 2 hours before taking my first pill of the day in order to replace the good bacteria.

 1  Diverticulitis Brown urine, tired, irritable, lack of energy, Not sure if it is from the meds however since I started my finger/joint has swelled and is so sore. It's hard to even drink water because everything taste like a rusty nickel. Medal taste in my mouth. I only have eleven more pills to take. I have an appointment tomorrow with the doctor to get a different antibiotic prescribed. This sucks, don't get me wrong, it's better than the pain of an intestine infection...

 4   Only MINOR side effects. The most annoying was feeling really tired and sleepy all the time. Metallic taste. Nausea only if I didn't eat sufficiently BEFORE taking a tablet. I made sure to avoid alcohol completely and after one bout of bad nausea, made sure to eat a decent amount before taking each pill (tea and toast is NOT enough). Found the side effects ok and worth putting up with in order to clear up the infection this med was prescribed for. Unless the side effects were extreme, I would not stop taking any medication without my doc's advice. Better to ask if you can take a lower dose more times per day. Sorry, but some people here seem to be complaining about next to nothing. Try dealing with chemo side effects and then see what you'll put up with to get better! F 41 7 days

 3  BV I'm only on day 3 (4 more days to go...ugh!). Really lethargic and have had non-stop headaches. Got really nauseus last night and thought I was going to vomit but it went away thankfully. To the people who say to the others below, you obviously didn't read the instructions...I have read the instructions thoroughly (they probably did too), some of us are just not as lucky as you to avoid the adverse reactions to this drug. I've been taking them with plenty of food and water and still don't feel great. But thank you to everyone who comments here because (even though I'm sorry you're all feeling bad too) it's nice to hear that others are experiencing the same things and it's not just me! :0) Didn't realize there was a gel option, would definitely try that instead next time!

I read two comments that mentioned bloating but I feel like I'm retaining a lot of water.

 4  BV I felt like I was on the verge of getting sick, lethargic, fatigued, moody, sensitive, lack of real appetite and on the verge of crying most of the time. It didn't matter if I slept a long hours or shorter hours, I still felt as tired, emotional and unmotivated to do anything. I was pretty sure it was the antibiotics and not hormonal mood swings as I just past the pms and period time. I was given this at Planned Parenthood. I have had this drug before [i didn't feel this crappy] but I'm not sure if I was given a lower dosage or what but I felt really horrible the first few hours of taking this drug, like I was getting the flu. All I wanted to do was sleep and found myself extremely cranky. I had the option to take the gel but I thought taking a pill would be less awkward. I forgot about the side effects. I didn't take this on an empty stomach and I didn't drink at all. Today is the 2nd to last day and I can't wait to get off of it. Despite all of these things, if this is what it takes to get rid of the funky smell and itch down there, then I'll take it. However, I might opt for the gel medication and not lose a week of my life to the extreme fatigue inducer known as Metronidazole. F 30 7 days

 5  BV None. Slight nausea on the occasion I took the pill before eating. My doctor gave me a sheet about Metronidazole. I READ IT. Obviously anyone having problems with this drug either failed to read about the drug they were taking, or failed to obey the instructions they were given.

 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. So, feeling good, off to a birthday party tonight and, yes, I will certainly be having a couple of drinks. F 43 3 days

I thought I was going mad due to the side effects,and the tablets affected my potassium level which resulted in more problems.I have to say I did need them for the infection but did not take the full course as they made me feel weird very early on.
