"Started taking Flagyl for bacterial vaginitis on Friday. Didn't start feeling side effects until late Saturday, where I experienced flu-like symptoms. It is now Tuesday, and I can't wait until my last dose. I am taking 500 mg every 12 hours for 7 days. I also have interstitial cystitis, which I think the medicine is irritating my bladder. Fatigue is the worst symptom so far, doesn't help when I work midnights and am already tired. No diarrhea though, and no yeast infection yet. When they prescribed it to me, I was not happy! I just tell myself the benefits outweigh the risks. I just hope my interstitial cystitis symptoms subside when this is done."

"I took this in February of 2008, and in December 2008, I was diagnosed with the same bacterial infection again. The doctor said this is the best medicine available to kill the bacteria. The pills are horrible to take since they are not coated. I've experienced the metallic taste and stomach upset feelings. However, if they work, I am willing to withstand this temporary inconvenience."

"I was given this medication after the doctor discovered a very serious bacterial infection. The doctor said I must have had it for a very long time. Yeah. At least 3 years. I felt like I was dying from the inside out. I feel like the doctor AND this medication saved my life. The medication worked fabulously! I had no problems whatsoever. No side effects. I didn't even notice the taste! (I swallowed them quickly!) I highly recommend this medication."

"This medication is dangerous. As someone who does not typically have reactions to medications, I must tell anyone taking this medication to be completely aware of this medication's side effects and STOP using the medication if you start to experience any of them. I started this medication for BV (500 mg/bid). By day 4 of 7, I started having tingling down my arms, across my chest, and a general sense of not feeling well. On the fifth morning, the tingling was more intense, and I was feeling pressure across my chest. As a 55-year-old female, I was concerned about a heart attack and took the hit and went to the ED. Shame on me for not being fully aware of this medication's side effects. It wasn't until I was released from the ED, without addressing the tingling down my arms and chest, that I researched this as a medication side effect. When I called the Urgent Care who prescribed the medication, they totally wanted to dismiss the tingling as not a side effect - yet said to stop the medication anyway. Still recovering."

"I was prescribed the 7-day, 3 times a day dose for BV. As to symptoms clearing/persisting, I wouldn't know because I didn't notice anything amiss to begin with (no noticeable smell or discharge). The GYN recommended Flagyl after my annual appointment, possibly because I was developing BV. I don't know if it's the medicine, but I developed the worst sore throat I've had in years. Congestion interspersed with a runny nose, sinus pressure, throat pain, sneezing, coughing, raw nose, the works. It feels like a mix between strep throat and a sinus infection. I feel like my head is in a vice. The only other thing that's changed is darker urine than usual. I'm on my last pill, and I started getting sick on day 4 of antibiotics."

"Ok, so I didn't know what was going on. This medicine has totally changed. My side effects are nausea, lower back pain every time I stand, mouth taste blah, and tired. Oh, gas and diarrhea. I'm so glad tomorrow is my last day. The best advice I can give is to eat heavy."

"This medicine works so well! The smell and heavy discharge were gone within 2 days of this 10-day medication. A lot of other people report feeling sick and restless, but this was not my experience at all. The only side effect I experienced was lightheadedness due to the medicine's ability to dehydrate the body. The only thing that really sucks about this medication is not being able to drink alcohol-- and seriously, don't even attempt it. You will thank me later."

"Coming off a long bout with diarrhea (unknown causation). Very run down with constant diarrhea, but it was slowing. Developed a UTI, and the doctor prescribed Flagyl. Lots of warnings about alcohol and mouthwash. Took one tablet and became nauseous. Started vomiting. Today (second day), nausea and vomiting continued. Dehydrated and went to the ER for rehydration, anti-nausea IV, and a prescription for a new antibiotic. Still can’t take the new antibiotic because it must be taken with food, and I can’t keep any food or liquid down (11 pm, second day). Anti-nausea meds (Zofran) slow to kick in because, as the nurse explained, Flagyl (1 tablet) is still in my system. Flagyl may be fine, but be very careful. If you are prone to nausea or seasickness, or just don’t trust your tummy, do not take this. Ask for another antibiotic. Even the pharmacist, after hearing of my experience when my husband filled prescriptions today, commented that Flagyl is wretched on the stomach."

"I've taken Flagyl several times for severe sinus infections. It did help considering the side effects. Currently, I began Flagyl 5 days ago 3 times a day for C. diff. The C. diff symptoms were bad enough, but the side effects this time are horrible. Severe nausea, insomnia, itchy hot skin, and a general feeling of sickness. I still have 5 more days to go and want to discontinue the medicines."

"Was prescribed Flagyl for BV but was never entirely sure I even had it as no tests were conducted. Took the pills and am so happy tomorrow is my last day! Literally the worst side effects ever, day one wasn't so bad, just had a metallic taste in my mouth, but every other day I've experienced headaches, nausea, and extreme fatigue to where I'm sleeping all day. The medication is so much worse than the slight issues I even had."

"After intercourse with my boyfriend (no condom), I developed a strange odor and unusual discharge. I knew it wasn't the same as my usual discharge. I went to the doctor and was diagnosed with BV (I feel like I actually had trich, but apparently it's hard to test for that, so BV it was!) I took this medicine after trying to treat it with probiotic and vitamin C ovules to no avail. I did experience very mild nausea and softer stool, as expected with antibiotics. By the end of the week, wasn't sure it was 100% gone because after I finished the course of Flagyl, my period came, and I was scared that the BV would come back, as other ladies have experienced. Luckily, everything was still back to normal despite my period. So far, I've been BV-free for 3 weeks. It was clear that this infection was caused by sex and not by any internal imbalance, so hopefully it will stay away. I learned my lesson to always, always wear condoms because this problem is gross to have. I also now take daily probiotics, which is great support for our bodies. So glad it's gone. I pray that all you ladies will find a cure if this hasn't worked for you!"

"I really don't understand all the negative reviews for this medicine. I've been on it for three solid days now and have had absolutely no issues. I'm taking 500 mg, one pill twice a day. I've been taking it after lunch and dinner and haven't had any issues with diarrhea, nausea, or dizziness. As for people complaining about the taste of the pill, how are you even able to know what it tastes like? It should be in your mouth for less than a second, just swallow it down with a glass of water or some orange juice."

"Flagyl also ruined my life. I was healthy and now I have panic attacks and muscle weakness. Only took 2 days' worth, but three weeks later still feeling like someone else. Dizziness and nausea. Be careful with this."

"I was diagnosed with SIBO (small intestine bacterial overgrowth) in July of this year. Had my first round of antibiotics in August (21 days). I'm now on my 2nd round of antibiotics, this time I’m on 500 mg of Flagyl and 875 mg of Augmentin. I’m about 2 weeks in or 14 days in, and I feel horrible. Back pain, pain in both my feet and hands. Dizziness, very fatigued. All I want to do is sleep. I had changes in my urine and stools. Went to the ER because I thought I was literally going to die. I suffer from anxiety, so this medication just makes it worse. I have a racing heart rate, and all my labs and CT of my organs came back normal, thank God. Funny how meds can fix one thing but cause all sorts of other things."

"I was prescribed a 500 mg 3x a day dosage for 10 days. I always have issues with antibiotics, but this by far is the worst side effects I've ever had! The metallic taste, diarrhea, headaches, and overall feeling are horrible. I just completed day 5, and it was so bad that I wanted to stick my fingers down my throat and force myself to throw up! I also started to develop oral thrush! The medicine does seem to be working, but I'm not taking all 10 days. I feel like I can barely make it to 7!!"

"Oh my! I have experienced bloating, gas, and abdominal pain since taking this medicine. The infection does not seem to be clearing up, and I only have one day left of a 7-day course of 500 mg twice a day. I am tired, have insomnia, and will not take this again. My abdominal pain is extreme! I have been up since 3 a.m. and took it this morning; immediately took a bulking laxative after to put something in my stomach. Will see if this helps!"

"This is my third time with diverticulitis and have taken Flagyl and Cipro combo each time. I'm currently on day 7 of the course, and it has relieved the pain early on each time. So for that, it is highly effective. The downside is that you can't drink alcohol. It also leaves a terrible metallic taste, as well as dry mouth, which is hard to deal with and annoying to say the least. Slight nausea from time to time as well."

"I took Flagyl x 2 for 5 days for BV last month, having suffered bacterial vaginitis for over a year. I had tried natural remedies that just did not work, so as a last resort in utter frustration, I turned to Flagyl despite having read such awful reviews about it. I experienced no side effects at all from it until the very last day when I suffered a mild upset stomach. All signs of the BV were completely gone by the end of the week following when I completed the course of antibiotics, which was fantastic, however, since then I have reasonably frequent stomach upsets after eating. I'd rather have that rather than have BV, so a small price to pay. As antibiotics kill off all bacteria, both good and bad, I have now been loading up on probiotics in an attempt to put good bacteria back into my body. This medication did work for me for BV, and I'm so thankful that it's gone at last."

"This drug almost killed me. I took 400 mg twice a day for 5 days. The first day was okay. The second day, I experienced stomachache, agitation, insomnia, nausea, hallucination, and nightmares. The third day, I rushed to the hospital with blurred vision, which lasted for over 11 hours. Never again."

"I was in the hospital for extreme pain in my tummy, vomiting and diarrhea at the same time, which later turned into vomiting and pooping blood. Diagnosed with colitis. She also said it was a BI. I stayed a day because the pain was so bad, and I couldn't keep anything down, so I was given morphine by IV until I could keep fluids down. Also on Flagyl 500 3x a day and Cipro 500 2x a day for 14 days. On my 4th day, and this medicine has been a lifesaver!! I've lost 6 pounds in 4 days. I'm only eating a couple of crackers and soup juice. Nothing tastes right. Some foods have a metal taste. Also, it makes me ache like I have the flu. But nothing like the pain I was in before! I will take these few side effects before going through the pain I had before."

"I can't express enough how much this pill has helped! I'm taking it for BV. My symptoms were gone by day 3. I should add that I have severe allergies to many strands of antibiotics (I'm talking epi-pen type allergies). For me to be able to take this with almost zero side effects is amazing. I had a slight headache day 2, and I sort of feel like I'm always hungry, but I would take any side effect for 7 days over the smell of BV!"

"I was prescribed Flagyl for 7 days, 3 times a day. It is awful, this medicine has kept me with a headache, nauseated, and vomiting. Today is number 6, and I'm dreading the last day. I just want to be normal again!!"

"Before I started this medicine, I was so worried because of all the reviews about bad side effects. I can honestly say I did not have a bad experience at all. I was on 500 mg twice a day for 7 days. The 2nd day I was on it, I had very slight nausea in the evening, but I started watching T.V., and when the show was over, my nausea was gone. The 3rd day, I had some wine, and I was on my 2nd glass when I remembered I'm not supposed to drink while on Flagyl. I just finished my last dose and haven't experienced any more nausea or anything. I've been lethargic the last 2 days, but that may be due to getting my period. Not everyone has a bad reaction!"

"This cleared up my BV well, however, I was experiencing some strange side effects. I'm having symptoms similar to a sinus infection-pressure and pain in my temples, pain behind my eye, my eye was swollen, as well as a runny nose. I've stopped taking the medication, so I hope these symptoms pass. The same thing happened the last time I took this medication too."

"This medication worked wonders! I was a little skeptical about it from doing research, but with anything you Google search, if you dig around long enough, you will eventually find something scary. I have had no diarrhea while on this medication, as some of the complaints were mostly about diarrhea, nausea, headaches, and cramps. Let me tell you, drink PLENTY of water! Don't drink soda, tea, punch, etc. I mean straight-up water! I also picked up Kefir; it's a cultured low-fat milk smoothie. It will do wonders for your stomach! I also took Zantac 150 mg 30 minutes before taking the Metro pill. The only side effect I have had was a tender tongue under my chin. P.S. If your urine is dark (a common complaint by most), you need more water, people! Hope this helps you!"
