For Skin or Soft Tissue Infection "Absolutely awful reaction to this drug, Flagyl. I have never been so sick on any medication. Was prescribed for a puncture wound to avoid infection but honestly cannot say if it worked or not, although the infection was prevented. However, I was completely dysfunctional with side effects from the Flagyl, including shocking headache, sore throat, hallucinations, dizziness, sore back, upset stomach, sinus reaction, and extreme fatigue."

For Bacterial Infection "I take this medicine with amoxicillin because I had a severe tooth infection and the pain was horrible. After 3 to 4 days, slowly I felt better. I feel dizzy, have a stomachache, and am sleepy sometimes, but it is okay. I will continue this meds until 10 days. I hope and pray everything will be okay after that."

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 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 "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 "So far, I have had some stomach cramping, but at least the doctor in the hospital told me what to expect. I'm getting better."
