Flagyl (metronidazole) "Was prescribed Flagyl for Diverticulitis. All I can say is that I had to stop this medication after 6 days. My side effects included: numbness and tingling of my hands, dark urine, high anxiety, headaches, diarrhea, stomach pain, nausea, and difficulty sleeping. My dosage was 2x250mg tabs three times a day. I am in my 60's and without a doubt this is the medication that has given me the most side effects."

"I wonder why the companies that make this a pill don’t put it in a capsule or a coating on it. It tastes so bitter and it melts in an instant when I put it in my mouth. Several times I choked on it. All because they didn’t put a coating on this medicine. Do they intent to torture people or can’t they think about something as simple as this?"

Flagyl (metronidazole) "My doctor gave me this because I had bacterial vaginosis. Not even 12 hours in to my first dose, I got the metallic taste in my mouth, then severe stomach cramps and nausea. I'm on day 5 and have had bouts of nausea throughout the course of my medication. My appetite has gone way, way down and I'm SO tired! I literally will sleep 12 hours and then get up for 2 then go back to bed for another 4! Having trouble staying awake at work, but it is doing its job! "

"Omg, I loathe taking these pills it's all I can think about all day and I'm only on day 3, of a 7 day treatment for BV. I feel awful severe headache, fatigue that has kept me in the bed all 3 days, nausea, loss of my appetite, dizziness, bloated, gassy, muscle aches like I have the flu, is there nothing with less side effects to take for this??. I barely had any BV symptoms to start with I feel like a dysfunctional zombie. There's no way I'm gonna make it through 4 more days I can't function like this. Everyone's body is different my body doesn't react well to this"

Flagyl (metronidazole) "Was given instructions to take this Flagyl twice a day for 7 days , every 12 hours for BV ( bacterial Vaginitis ) . First day I had a slight headache, second day of taking it symptoms of BV were gone ! No smell , discharge but I had a backache which wasn’t too bad. Still taking it to finish up treatment. But I give it 9/10 because the medicine taste HORRIBLE! Take with food or thick liquids to avoid the taste."

"Was prescribed metronidazaole because of my diarrhea in the event it was caused my bacteria. Worst experience ever. Gave me oral thrush that has been impossible to get rid of. Made me dizzy, couldn’t sleep, anxious, depressed. I felt totally out of my mind to the point I had to meet with a psychiatrist. I never mentally felt like that in my life. Horrible medication. Took for maybe a week and a half until I couldn’t do it anymore."

Flagyl (metronidazole) "Everyone's body will react differently to meds, genetics. Just bc I had a bad experience, doesn't mean you will. Took w full stomach of bland food, 16 oz water, & took a daily probiotic. My experience w this med was horrible. I was unbearably anxious, rapid heartbeat, intense pelvic pressure, bad stomach cramping, nonstop nausea, vomiting, & explosive diarrhea. This was my 2nd time w this med,w the same bad reaction. I had to discontinue, both times. Took 3 days to start feeling better, 5-7 until normal. I'll never take this med again. I'm sure it's good for others, but nit me. I had cancer so I've taken a lot of meds. Never had to stop another med from side effects before, but I was scared to the point of going to the er. Never again."

Flagyl (metronidazole) "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."

Flagyl (metronidazole) "Just finished my 7th day of flagyl. This is my second time taking it And this time was definitely easier. I usually take the pill with a fizzy drink, seems like I swallow it easier that way. Also I noticed the main side effect I’m having this time is vaginal itch. I’m pretty sure that’s from the medicine because I didn’t feel itchy before I started flagyl. Doesn’t seem like a yeast infection though because I don’t see any discharge. My vagina definitely feels fresh though and this medicine definltely works towards BV. I hate that I suffer from BV but I’m happy there’s at least something that helps."

Flagyl (metronidazole) "I have taken flagyl multiple times for bv. I hate it each time. I tried Clindamycin but it wasn’t as effective. I took the pills with chocolate milk for the first few days, then orange juice then I finally saw where to wrap fruit roll up around the pill. I wish I would’ve known about that a long time ago. It helped a lot. My side effects were: dizzy, drowsy, stomach ache, heartburn, kinda blurry vision, headaches, back pain, frequent urination, dark urine, not much diarrhea, nausea, finally didn’t have a metallic taste but the after taste was awful. After taking the medication, it did give me a yeast infection which was expected. Really please try the fruit roll up method, it help a lot even with my last tablet."

Flagyl (metronidazole) "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."

Flagyl (metronidazole) "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."

"Given for 7 days, twice a day for bacterial vaginitis. I dipped the pill in honey and took after full meals with lots of liquids. Never tasted it at all. Side effect of dry mouth with slight nausea but ate a little more on top of dose. I'm now on sixth day and feel horrible. I don't know if I actually have the flu or if this is side effect of the medicines. I'm achy, chills, dizzy, sore throat, and headaches. Don't want to continue if these are serious side effects, but if I stop it may cause treatment to have been in vain! It has cleared up all symptoms of infection though."

"Within a couple days of taking Metronidazale the infection cleared up, in that aspect I feel 100% better! But the symptoms of the antibiotics are terrible.. my entire body aches, I feel exhausted, my toes and fingers are tingling, I have no appetite I have to force myself to eat something in order to take the medicine, bad diarrhea. I have a couple more days of this and I can't wait to be done!"

Flagyl (metronidazole) "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!"

Flagyl (metronidazole) "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."

Flagyl (metronidazole) "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."

Flagyl (metronidazole) "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."

"This has to be the worst medication I’ve ever taken. It doesn’t matter what time I take it or with food it makes me extremely nauseous. I have the worst taste in my mouth. I hate it and will never take it again."

Flagyl (metronidazole) "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!"

Flagyl (metronidazole) "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."

Flagyl (metronidazole) "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."

Flagyl (metronidazole) "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!"
