For Bacterial Infection "I get recurring bacterial vaginitis. This medication is the only one that works. I've used tea tree oil suppositories and 500 mg boric acid suppositories. You can possibly get a yeast infection if you are sensitive. Boric acid suppositories are the only thing that works for clearing up a yeast infection. Bacteria that cause bacterial vaginitis can be held in the urethra of a man, so I would be aware of recurring infections with the same partner. Maybe get him treated also. Keep your sugar intake low. Strengthen your immune system. The gel is more expensive but seems to be soothing. The pills will get you well, but do NOT ingest alcohol at all, or you will get violently ill. I forgot at a work function once, never again!"

For Bacterial Infection "I was given Flagyl for my bacterial vaginosis (BV). The pill has a horrible taste to it, and to make matters worse, it can leave you feeling groggy and give you a head fog with nausea. It does work like a charm for trich and BV. This is maybe the 6th time in my life taking it, so I think my body has gotten used to it, but I'd rather deal with these side effects than the ones of nasty, smelly BV."

For Bacterial Infection "I've been taking Flagyl 500 mg twice a day for 6 days now for bacterial vaginitis. I almost decided to give up on sex, but I told my new boyfriend that we have to be extra careful next time. Wash our hands like a surgeon. I'm not even sure I want to have oral sex anymore. I just don't think it is worth it. Is it possible not to get an infection with oral? I am at the home stretch. I have that metallic taste in my mouth and nausea. I'm also fatigued, but I am a mother of two girls and it could be anything. My doctor actually prescribed this medication for 10 days, but I'm only doing it for 7. My symptoms are gone, and I just wanted to comment because I like reading other people's stories. It really helps me not feel so alone."

For Bacterial Infection "I'm using it for a five-day period for a bacterial infection, twice a day. I think it's working. It's my fourth day, and it was the only day I felt slight irritation. I'm not sure if that means it has stopped working or what, but I hope that after my last day, I finally get full ease. My only side effects are headache, dizziness, and nausea, which aren't so bad. As for the taste, I don't keep it on my tongue long enough to get a good taste, so I can't testify for that."

For Surgical Prophylaxis "9 tablets down in 3 days due to hemorrhoidectomy surgery, and I feel so sick: severe heartburn, severe nausea, top center abdomen pain, anxiety has gone up, and a general feeling of being unwell. I can’t continue the dose anymore, I can’t remember when I felt this bad ever."

For Intraabdominal Infection "Flagyl was prescribed to me after an appendectomy with a leaking appendix. I took 3 doses at home, and the side effects started immediately and became more severe with every subsequent dose. I was dizzy to the point of having to hold on to the wall to walk. I had the worst metallic bad taste in my mouth that actually made everything taste horrible (water, juices, food, etc.). I was extremely nauseous to the point that I started heaving even with liquids. I had severe diarrhea as well, which I am not sure was related to Flagyl or not, but subsided once I was off that medicine. I was changed to Cypro and have been feeling much, much better with that antibiotic. In my case, I will NEVER take Flagyl again, based on the severe reaction I've experienced."

For Bacterial Infection "I’m taking Flagyl for 7 days due to BV, and boy, I tell ya, this sucker is war. I started feeling the effects mainly on the 3rd or 4th day. Horrible nausea/morning sickness, heartburn, dizziness, and headache. I constantly feel on the urge of vomiting, but it won’t come. I’m so tired and also feel super bloated. I hope when I’m done, these side effects subside. It’s helped the bacterial vaginosis, but lord have mercy, I’m seeing stars. So happy my last day is tomorrow! Plus, the taste is absolutely horrid. It’s 2021, I’m sure they can mask the pill somehow."

For Bacterial Infection "I have taken a number of medications in my life, but this stuff has to be the worst experience of my life. I felt so sick: nausea, vomiting, stomach aches, dark urine, and felt very depressed and very tired. I definitely will never, ever take this stuff again. I'm certain it made my life a nightmare!"

For Helicobacter Pylori Infection "One of the worst meds I've ever had the misfortune to use. In addition to making me feel continuously nauseous, it affects the saliva in your mouth. Your saliva is as if you have chewed on the most possible bitter thing you can think of. Saliva is bitter 24/7, which in turn causes what little food you can tolerate to taste wretched. Dosage was three times a day for 14 days. After day 7, I reduced it to twice a day, which has helped the symptoms of nausea and bitter saliva a little, which is better than nothing. Otherwise, I would have stopped taking it altogether. I'm depending on the clarithromycin to pick up the slack."

For Bacterial Infection "Was put on this for 7 days, 2x a day, 500 mg. For BV. I'm on day 6, and I'm miserable. Considering not doing day 7, but we will see. Will try my best. It wasn't until day 2/3 that I started having noticeable side effects. I thought I was just being emotional. They got worse as the days went on. Super tired. Major brain fog. Symptoms of depression (and considering I've been both depressed and suicidal in the past, this is not ideal). Very unmotivated. Nauseous. Warm, tingly feeling. Diarrhea, but no stomach pain. Overall sick feeling. Just don't feel like myself. I also am thinking this is ironically affecting my vaginal discharge more than ever."

For Bacterial Infection "Prescribed this drug to take twice a day for 7 days for BV. Noticed after day two the symptoms were subsiding. For the first 6 days, I took it straight after lunch and dinner with a bottle of water. Had barely any side effects apart from on day 3 I woke up feeling nauseous and with a headache, but nothing major at all. And on day 7 I forgot to take the drug after my dinner, so I ended up taking it 4 hours later and noticed a slight tummy ache. Overall, I would definitely recommend this drug for BV."

For Bacterial Infection "The first time I had BV, I was given cream for 5 days that worked fine. The second time with BV, I had pills, they were better than cream. 3rd time with BV, pill again for 7 days. After day 2, the worst side effects I ever had with any meds, only on day 4, and don't want to take anymore pills. Metal taste in mouth, constant nausea, headaches. I hate this pill, but it seems it's taking long to clear up. Still having discharge, I'd rather have the cream."

For Diverticulitis "Waves of nausea and constipation. Seemed to settle the diverticular symptoms at least. Makes you feel generally crap, and I can't wait to have the last dose behind me. Worth asking if there are alternatives."

For Bacterial Infection "I was prescribed Flagyl 500 mg 2/day for 7 days to treat an infection. The infection cleared in 3 days, however, the potency of this drug is extreme. I felt completely drained, no energy, and extremely nauseated to the point of not knowing if I was going to be sick or not. Cold sweats, chills, and dizziness, as well as feeling irritable. DO NOT DRINK ALCOHOL. I am no stranger to a few beers a day, a glass of red wine, etc. I didn’t think that a beer would make me so sick. This drug prevents the body from breaking down alcohol properly, and you WILL pay for it. It is a fast-hitting sickness you will never forget. Take the meds, it will pay off in the end to cure your infection 100%. The side effects are real, and they are rough… Strongest advice is to steer clear of even a drop of alcohol as this makes these effects worse."

For Helicobacter Pylori Infection "Started taking this for the H. pylori infection and I dread it. My doctors have me on it three times a day for two weeks, I am currently on day 8 and the side effects of the drug have not lessened or gotten better. Nausea, vomiting, gas, diarrhea, terrible headaches, and feeling like I’m a ghost overshadowing my body have all been side effects. It hits me the worst in the morning and at night because that is when my stomach is empty. I have found that food helps during the day, but not full and complete meals. I definitely do not recommend this drug to anyone and I am sorry if you, the reader, are taking it with hopes that it won’t make you sick because chances are, it probably will. But please do not let this deter you, it hurts but it will make you feel better in the end. Important note: the drug can make you have EXTREMELY dark and brassy colored pee."

For Trichomoniasis "I was prescribed two x 400 mg tablets a day for 7 days. No side effects, and symptoms went away almost immediately. But then they returned 3 weeks later, and a follow-up test showed I was still positive. The infection had caused fluid buildup in my uterus, and I am booked for surgery to release it tomorrow. So my doctor put me on 2 x 400 mg tablets twice a day (so 1600 mg a day total) until the surgery. The first four days were fine. But the last two days have been awful. As soon as I took them after breakfast yesterday morning, I started feeling nauseated. I have been taking 8 mg of Zofran every 8 hours to try to reduce the nausea. I took my last dose of Flagyl this morning, and I only felt I could eat something small now at 11 pm, which is an hour before I start fasting for surgery prep. I really hope the nausea is gone tomorrow before I go under anesthesia. Symptoms have cleared again, but I hope it’s for good this time. I’ll be asking for a different antibiotic if there’s a next time."

For Bacterial Infection "On Flagyl, my urine turned a very dark color no matter how much water I’d drink. The first day, I had stomach cramps, but nothing too crazy. I had little to no appetite, but I HIGHLY recommend getting in two meals to take with each pill (I’d like to think this fights back against nausea and headache). Did the 2 pills for 7 days package. All in all, the BV cleared up, but I wouldn’t want to take this again."

For Bacterial Infection "Had an abscessed tooth, decided to take Flagyl. Didn't even know I was experiencing the symptoms everyone is complaining about till I read these comments. My urine is definitely very dark compared to normal, the taste I thought was infection draining in my mouth, it was the only thing that would make sense as to why I have a pretty rotten taste in my mouth, anxious and I feel a little distant. My stomach is feeling a bit nauseous, and I kind of feel generally out of it. With that said, the excruciating pain diminished over the 3 days, and that one thing was worth 50-fold of the side effects. If you sit around self-analyzing how you feel, you're probably going to notice every bell and whistle, but if you just go about your day like any other, you might find you didn't even know you were experiencing side effects until you read horror stories online. The abscessed tooth was a horror story, Flagyl was the happy ending."

For Bacterial Infection "I had to take the drug every 8 hours for 7 days. All the other reviews claiming this drug gives horrible side effects are false. For the first 3 days, I had slight nausea, nothing unbearable. The last day, I made the mistake of splitting the pill to make it easier to swallow, which was a bad idea. I got extreme nausea and couldn't sleep for hours. Only cons of this pill are the taste, the pill starts dissolving as soon as it hits your tongue. It is a pretty big pill, which is why I cut it in half. Just stick with the size though. On the third day of taking this medication, the discharge and smell of BV were completely gone. I would take this drug again, the minor side effects sure beat having BV."
