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 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 "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 Dental Abscess "Absolutely avoid! I'm a 29-year-old male, rarely if ever take medication, but unfortunately developed periodontitis due to a wisdom tooth. My dentist prescribed me Flagyl and warned me about possible stomach side effects. I took three pills, 400 mg, and woke up the next day a different person. I felt as if I had been poisoned, my head felt like a bowling ball, and I felt like I was going to fall over when I stood up. I slept all day and didn't eat a thing. I noticed later that day I could hardly breathe and that my nose was blocked. I had an awful headache, and my eyes kept squinting and were sensitive to light, urine was a dark color, and my appetite was diminished to zero. It took a solid four days before I ate anything and was bedridden 90% of that time. I am still feeling the effects from it (weakness, dizziness, weird vision issues). Peer-reviewed journal articles highlight many other young people, ages ranging from 22-25, with adverse side effects who NEVER recovered."

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 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 Bacterial Infection "The side effects for me haven't been good, but I'd rather finish the medication than have my infection come back and be resistant to the antibiotics. I have darkened urine, cramping in my lower abdomen, headache, hurting reddish eyes, tiredness, fluctuating levels of concentration, sadness. I have 3 days left of the pills, and it's 3 am now. I woke up from my sleep due to heavy pain in my legs and body, and overheating (though I don't feel feverish). 2 days ago, I went on a walk after not doing so for weeks, but I don't think that caused it. I've been sore from walking before, and this is a higher level of pain than that. I didn't even walk for that long, and the jobs I've had require standing and walking around all day. So it's weird. My legs hurt so bad. But it is clearing up my infection, so I'll finish the regimen so I can be fully well and back to normal."

For Bacterial Infection "So I have panic disorder and anxiety like many other people here. I delayed taking it because of side effects, like many people here. However, my approach was to take one pill on the first day to see how I responded, then two on the second. I am NOT a doctor, so don’t do this if you don’t want to. But for me, it helped the anxiety and also helped to discover how I would tolerate it. I take it as prescribed now and have had mild stomach upset, but nothing serious or debilitating. I notice dizziness occasionally, but that’s likely because you have to drink quite a bit of water with Flagyl, and I am not great at drinking water. I drink coffee and have no issues with anxiety or increased heart rate. I went for a 6-mile walk, no issues at all. I’ve also not had any headaches associated with it either. So, for those who are afraid to take it, take it as prescribed and trust that your doctor prescribed it because the benefits outweigh the costs."

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 Diverticulitis "In combination with Cipro, it helps make the pain go away. I'm stuck on a flare somehow. I've learned if you take these 90 minutes apart, you don't get nearly as bad stomach problems. Used to get moderate headaches from these 2."

For Bacterial Infection "I was prescribed this medicine to treat BV. I was told to take 5 400 mg pills in one dose. This sounded wrong to me, so I decided to have a look online and wished I never! I saw people sharing stories of really horrible side effects such as headache, dizzy spells, and vomiting. Being emetophobic, this really worried me, and I was debating if I'd even take the pills! Eventually, I decided to take them as instructed, on a full stomach, with a large glass of water at night. They did taste a bit horrible, but nothing as bad as I'd read. Once I'd taken them, the taste was gone. I didn't have any dizziness or nausea, nothing, absolutely fine. I think some people have exaggerated their side effects majorly!"
