Reviews for Metronidazole

“I was diagnosed with Trich & BV. Had to take 500 mg of 4 pills at once. I was scared after reading reviews. But I knew I had to take them to feel better. Ate before I took them. I felt hot & a little headache & had gas a little about an hour-2 after I took them. It ceased. Got tired & went to bed. Woke up with the metallic taste in my mouth. But nothing that is too bad or I cant handle. But today I feel better already. Even got my energy back. This was a lesson learned to use protection or don't have sex. This was the consequence of my stupidity. I can't blame anybody but myself.”

Flagyl (metronidazole): “Was prescribed Flagyl for trich. I was skeptical and scared after reading the reviews because everyone made this medication seem terrible. This is my second time taking it and have not have one symptom either time. The first time I was prescribed a one day dose of the four 500 mg pills. This time the 7 day dose. I’m on day 3 and feel better. The smell has gone away and so has the itch. I feel like a new woman. I would suggest taking this antibiotic on a full stomach or drink it with a glass of milk. I promise, it’s no where as bad as everyone makes it seem. My anxiety was through the roof after reading these reviews, but I womaned up and took it. Yes the taste is absolutely terrible so please don’t roll it around on your tongue. I hope this helps ease someone else’s anxiety.”

Make it go away. · Taken for 1 to 6 months February 12, 2019

“Has anyone experienced having trich which is resistant to metronidazole to it. First round took four 500mg of the meds, didn't work. Then was placed on two tablets 500mg for 7 days. It cleared up but as soon as I stopped the treatment it came back, but not as bad. Then the last time I was placed on 2000mg for 7 days. Once again, took it away but as soon as I stopped it came back, once again not as bad. I'm fed up with this and I'd like to know why my body is not clearing up. Has anyone had this issue and then found some relief? Please share.”

“When I went into the ER, as I felt like ripping my insides out - down there. They diagnosed me with trichomoniasis. They gave me the one time dose fo 4 metronidazole 500g pills. I will tell tell you swallowing them was terrible. I made the mistake of taking two at once first. They got stuck in my throat, I choked, and they came up dissolved and some went into my nose from inside my mouth. I had the most awful taste in my mouth. BUT immediately got something to eat after and so far (7 hours later) I have experienced not one side effect. My symptoms are not fully gone, I’m still itchy a bit down there, but the discharge has already subsided and the itching IS getting better. The doctor says allow 7 days for medication to fully run its course. It’s an amazing medication that, in my experience, works far better and faster than any other antibiotic for any other diagnosis (not related to sti’s). Quickest relief by far, and luckily so, bc with this, relief is much needed. This girl, never ever wants to have sex again!”

“I was prescribed the 500mg 2 times a day for 7 days. The pill didn’t even taste that bad lol The only side effect I had was dark urine and diarrhea and that was on day 3 and 4. I’m approaching my 7th day with my last pill. So far it’s been good. I do want to warn you that might have discharge. It’s not always a yeast infection, it’s the medicine pushing the infection out.”

“Literally have taken every medication to clear Trichomoniasis and it’s not going away, reading the comments I’m glad I’m not the only person going through this. Been trying to consider natural remedies and boosting my immune system to help fight trich off. You aren’t alone ladies I know it’s hard but we will all get through this!”

“So I'm a female, I went in for an exam a month ago and my results came back positive for chlamydia. I was prescribed the 2 oral antibiotic tablets to take as one dosage. I didn't have symptoms of course beforehand and had some after taking the medicine, so I assume it was flushing out. So I went for my follow up a few weeks later and had another exam. I had trich and BV so I was prescribed the 4 pills of flagyl 500mg to take as one dosage, followed up by one dosage of diflucan 150 mg because I get yeast infections after taking antibiotics. I highly recommend taking the one dosage of four pills, instead of the seven or two days. I ate before taking the medicine, however later on in the day I felt nauseous. I had a metallic taste in my mouth even when trying to drink water, so I just slept it off. However, the next day I'm feeling great, no odor, no discharge, no nothing. And my results came back negative for any other STD's.”

Flagyl (metronidazole): “Omg reading all these comments scares me.. the doctor prescribed the 4 pills to take at once.. two days it was clearing up.. after my period came the trich came back. I went to get retested and I'm now waiting for results but I already know I still have this infection. This meds should work the first time . I guess it's not strong enough to kill the infection in one or even two doses.. I'm scared and I hope it goes away soon.”

“I had gotten diagnosed with trichomoniasis and they prescribed me this medication. The instructions were to take 4 pills at ONCE! (2000mg) I thought that was absurd. Naturally paranoid with taking medication in the first place I looked up the reviews and I did not see positive feedback, a lot of people said they had gotten sick or had heart palpitations so my anxiety kicked in and it took me four days to finally suck it up and take it. Well I took it before bed (it said dizziness may occur) and I went right to sleep. Woke up and felt nothing. Long story short, make sure you take it on a full stomach, take it before bed & you should be fine. Don’t let reviews scare you because chances are those people didn’t follow the instructions, you’ll be fine!”

“I had to take a one time dose of 4 500mg capsules. About two hours after taking the dose I had noticed I was feeling extremely tired. I was driving and decided to make my way home. So I wouldn't recommend driving. About 4 hours after, I felt a lot of nausea and general flu like symptoms. I felt like I needed to sleep but was unable to fall asleep. These symptoms were not unbearable. Its been 3 days since I've taken this medication and I still have minor side effects lingering. I have been having great sleeps, random nausea, vivid dreams and random bouts of fatigue. ALL of my symptoms from trichomoniasis have disappeared so I would recommend this medication.”

“Went for annual found out I had Trich had no idea or symptoms. I was prescribed the four 500mg in 1 single dose. After reading all of the reviews I was basically terrified to take the medicine so it took me a few days to get the courage to take it. I went out ate a big dinner took the med around 7:30 pm with a full bottle of water. I had minimum side effects slight head fog, mild rumbling tummy, and insomnia that night. Next day I was super tired but in all honesty the side effects I had were very easy to deal with. Praying it did it’s job when I go back to be retested if it’s cleared up will post an update.”

“Took the metronidazole 2g one time dose with full glass of water for trichomoniasis. Had some nausea about an hour later, but went away when I ate. Noticed a change in discharge and odor the next day. HOWEVER it's been a week and I've noticed odor again and I'm experiencing hip and lower back pain. I have not been sexually active not sure what's going on!”

“Was prescribed two doses of metronidazole to take orally. Experienced darker urine, nausea and a very bad taste in my mouth, but is it possible that this medicine can cause a yeast infection? I have been experiencing unusual discomfort in the vagina area.”

“It felt like metronidazole would kill me and not the bugs. Awful - four courses at different dosages and nothing. Tinidazole did the work in one treatment after suffering for months with Metronidazole. Fewer side effects with Tinidazole as well. A little more expensive, but it’s definitely worth it. Hope that helps someone who is struggling.”

“I was prescribed the 2000mg one time doseage. Yes the pills have a horrible taste but I'd rather taste that than have the symptoms of trich! I've taken the same meds for BV before and usually end up pretty tired after about 2 hours or so. I took this about 12 hours after a night of heavy drinking. Have felt a little nauseous and had loose stools and a little head ache. But it's been 3 hours since I've taken it and the odor is weaker and the discharge has dramatically decreased! Bye bye trich and bye bye cheating boyfriend that gave it to me!”

“Update: Flagyl is rough to take but it does the job for trich. Previously I would never take flagyl because of side effects but I had to tough it out because it's one of the few used to treat it and options were minimal. One dose option did not cure me on two separate occasions. The 2 -500 mg twice a day for 7 days did the trick. Lol Don't miss a dose and finish all pills WITH FOOD to help with side effects. It will work if taken correctly and don't read the bad reviews.”

“Didn't have symptoms of trich until about a month after having unprotected sex. I went to the health department and tested positive for trich. The nurse was very thorough with the exam process and suggested that I get multiple STD tests to make sure I was not positive for anything else. In short I took the 4 pills in 1 day. Actually as protocol the nurse had to observe me taking the medication. The pills worked and I noticed a huge difference by the next day. I plan to do a follow up to ensure I have been completely cured. ***PS- there are many complaints about the side effects of the antibiotics but I would rather the side effects to be cured rather than endure the horrible odor and other symptoms of trich.”

“So I went to the doctor and they told me I had trich and a yeast infection with cervical cancer. They prescribed me metronidazole 500mg then told to take 2x daily for 7 days but take 18 wouldn't that be 9 days. So anyways I'm all done no Yeast infection and no trich. Later I found out it wasn't cervical cancer it was just trich together with b.v and the yeast infection that made it look like cancer cell. But thank God till today I'm all clear no more unprotected sex......”

So done with good looks!! November 28, 2017

“So I was prescribed this medication for trich as some of you are familiar with from reading previously, well I got great results from the medication however I did get vaginal irritated itch with the discharge and it is a side affect, honestly, having unprotected sex isn't a smart thing to do, but thankfully Trich is curable and the itch is also. Keep in mind ladies no matter how clean good looking he might look, smell good he is probably not going to even know he is giving you more than a good five minutes of pleasure, it's 5 days of treatment that we carry now!!! Be smart !! good luck.”

“I was prescribed the Metronidazaole 2g mega dose after testing positive for trichomoniasis (had symptoms of pelvic pain, cloudy urine, and pain during the swab test). I opted for the single dose instead of a week because I hate antibiotics! Was really anxious to take the medicine due to many reviews saying it made them ill. I had basically zero adverse side effects! Took the pills about 30 minutes after eating a full mean (are pasta, and yogurt for dessert for the probiotics) and an hour before bed. Pills tasted bitter but nothing as bad as some reviews claim. Fell asleep with no problem. Had only a mild headache (if anything) the next day and no nausea. My symptoms (pelvic pain, pain during urination) seem to have stopped on day 2. Will get retested to be sure, but so far so good with this medicine! My advice: TAKE IT! Just eat 30 min before and stay hydrated! I also have been taking heavy duty probiotics since to help rebuild the good bacteria.”

“I was prescribed the one time dose of four (4) 500mg tablets. Within HOURS I noticed the horrible odor & discarge were totally gone!! I had been skeptical it would work well with just one dose but it's truly AMAZING!! I didn't have any of the (I personally think exaggerated) side effects some of these other reviews listed. I even took it on a completely empty stomach at the end of the day. No problems with the taste either as I take them differently than most people. I put water in my mouth, hold the water in my mouth without swallowing, tilt my head back (still not swallowing), drop the pills the back my throat & then swallow. I take many pills each day for various reasons & I've never tasted ANY pills that way.”

“Metronidazole is different for everyone. I’ve taken this antibiotic twice throughout my life and my body reacts poorly to it. I’ve been dealing with Trichomoniasis for almost 4 months now and I started off taking a dose of 4 pills in one night which didn’t clear any of my symptoms. That morning around 5am I started puking up blood and went to an urgent care in which they told me to never take that antibiotic again as it was tearing my stomach up. Please do not be scared of this post, my body has always reacted bad with metronidazole. I’ve tried countless antibiotics at this point to try and clear up the trich infection but nothings working. Maybe my strain of it is resistant? If anyone knows of anything please let me know I’m desperate for a cure.”
