"Tried taking Metronidazole (500 mg twice a day) for a BV infection. I am 20.5 weeks pregnant. After two doses I got numbness and tingling in my face. I immediately stopped the drug. Went to hosp and they feel it maybe an allergic reaction but don't know when the numbness will stop. Praying it goes away. Been 24 hrs."

"I just finished a 10 day treatment of 500mg every 12 hours. I am so glad it is over. I experienced stomach aches, metallic taste in mouth which I am still experiencing, as well as tingling/numbness in my tongue. I am also experiencing itchy & a burning sensation in the vaginal area it is uncomfortable. I hope it goes away soon. The only good thing about all this is that I don't have that fishy smell anymore."

"I took a week's worth of pills of this for a second BV flareup (tried Tindamax the first time and the BV came back) and I am confident enough now to write a positive review. All side effects (discharge, foul odor, stabbing pain) subsided by either the third or fourth day. So far so yeast infection, but I am being very proactive and taking probiotics daily and eating lots of yogurt. Side effects were very minimal and manageable, just a bit of fatigue and dizziness and light sensitivity. Nothing horrible. PRO TIP: Wrap the pills in bread before you swallow them. No metallic aftertaste at all if you do this!"

"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."

"I'm only on day 3 of meds, dose is 2 x a day for the week. Must say I see an improvement already! I've had BV for months and no prescription helped. I've tried things for my flora, ph, baths, alkaline water, vitamin c, you name it. 3 days in, and I'm already happier. No odor, no discharge, finally !!! Relief from this awful embarrassment. Yes, the pill can taste bad, however I take a sip of milk BEFORE and after taking the dose. Hadn't the 1st time and it tastes awful yes, but the milk coats your throat nicely and haven't tasted it since doing that. As for side effects I definitely have a suppressed appetite but I'm not complaining. The benefits of taking the Flagyl much outweigh any negative I can see."

"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 500mg 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 too 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."

"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 500mg 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 & haven't experienced anymore 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!"

"Coming off long bout with diarrhea (unknown causation). Very run down with constant diarrhea but it was slowing. Developed UTI and Dr. 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 ER for rehydration, anti-nausea IV and prescription for new antibiotic. Still can’t take 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) 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 other antibiotic. Even the pharmacist, after hearing of my experience when husband filled prescriptions today commented Flagyl is wretched on the stomach."

"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."

"After intercourse with my boyfriend (no condom), I developed a strange odour 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 causes by sex and not by any internal imbalance so hopefully it will stay away. I learnt my lesson to always always wear condoms because this problem is gross to have. I also now take daily probitotics which is great support for our bodies. So glad its gone I pray that all you ladies will find a cure if this hasn't worked for you!"

"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 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."

"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 x 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. "

"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 500mg twice a day. I am tired, have insomnia; and will not take this again. My abdominal pain is extreme! I have been up since 3am 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 down side 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."

"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 (500mg/bid). By day 4 of 7, 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 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 did I research 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 a 500mg 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 is 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 developed 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!!"

"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 500mg of Flagyl and 875mg 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 ER cause I thought I was literally going to die. I suffer from anxiety so this a medication just makes it worse. I have 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."

"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 metallic taste in 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."

"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 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."

"I had BV and was given flagyl to take twice daily for 7 days, and it cleared up the infection, but in true antibiotic fashion, it killed EVERYTHING! I ended up up with a raging yeast infection, and had to take fluconazole + probiotics after my regimen to replenish my good bacteria and kill the yeast infection that succeeded the BV. I think the probiotics are what have really maintained my health thus far..."

"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 this for my bacterial vaginitis infection about 2 weeks ago. I had the one dosage (4 tablets) treatment. The pills taste horrible. I experienced nausea good thing I took them before bedtime. My infection cleared up but now I think I have a yeast infection or it's just vaginal itching and discharge, nothing smelly, so I know it's not an infection. I'm guessing it's a side effect of the pills besides that they're really good!"
