Reviews for Metronidazole

Dranoel · Taken for less than 1 month April 6, 2021

“I've taken 3 rounds of metronidazole over my life, and never once experienced the side effects mentioned here. The odour disappears in a day or so, and my vagina feels/smells new and squeaky clean by the end of treatment! Everyone will react differently but I had to throw my 2 cents in as there are so many negative reviews for a drug that's been great for me.”

“Ladies this antibiotic metronidazole WORKS for metronidazole BV!! I experienced no side effects & I’m on day 5 of the treatment. I never usually take antibiotics for anything but I had reoccurring BV along with thrush - my immune system has collapsed as a result from stress... day 2 into this antibiotic and all BV had cleared!!!! I am so so impressed with it. I experienced no side effects which was surprising as I’m really sensitive! Don’t let the reviews scare you - everyone’s bodies are so different. Sending all you ladies strength - BV is such an awful experience to go through! X”

“I am on day 4 out of 7 taking this metronidazole antibiotic. I was prescribed 2 per day. I have awful fatigue and brain fogginess. I feel like I am in a dream, my stomach is so sick, I have super painful stomach cramping that had me in tears today. Diarrhea as well. I’m very nauseas even if I take this with food. This medication is very hard to take. I want to give up on it. I’ve never experienced side effects like this.”

“I'm always prescribed this for when I have bacterial vaginosis - 500mg 2x/day for 7 days. I always make sure to take it on a full stomach to avoid nausea. The only real side effect I experience is dark yellow/orange urine after taking it for a few days and goes away when I stop taking it, and slight nausea and loss of appetite. Like I said, having a full meal before taking it helps a lot. It works as intended. My only complaint is the horrible bitter taste when taking it, so to avoid that, I have to take it with extremely sweet drinks like some soda and try to swallow it fast so I don't taste it.”

“I also had the problem with the Bacterial Vaginosis (BV). I was so ashamed because of the horrible smell and discharge. I also had problems with the smell escaping my clothing and was so embarrassed to be around anyone. I am now taking metronidazole and it has worked wonders. No smell, no discharge or itching. I had no side effects. So thankful this medication is available! Saved my life!”

“I got a prescription for metronidazole for BV, and after reading reviews, I was terrified to start taking it - I was afraid of the side effects because the comments were so scary. I did eventually take it (2x400mg for 5 days), and literally had NO side effects (not even diarrhoea/nausea that I usually get from antibiotics). It cleared up my BV. I decided to write a review because I feel like other people might also get a wrong impression reading these reviews. Although some people will unfortunately have side effects, it's good to remember that most will not (and the ones that had a positive experience with the drug probably won't feel the need to even write reviews), so if you got a prescription for metronidazole, I recommend just taking it and not reading reviews in advance.”

“I have taken this pill metronidazole for one week; i.e. twice per day and the odour and vaginal discharge are all gone. I am praying they both don't come back. My vagina is now odourless. Thank God!!!”

Stevie April 30, 2020

“My experience is likely a rare case, but I do want to get this out there. I have taken Flagyl for BV in the past with no problems. I took it a few months ago and noticed an intense pain in my mid-back. It went away after a couple days so I ignored it. A week ago I was on it again and woke up on day 4 with the same back pain. 4 hours later it migrated to my upper abdomen. It was so intense I couldn't stand. I went to Urgent Care to find out that this dumpster fire of a drug gave me acute pancreatitis. I have never felt pain like this before and unfortunately my entire life, at only 28, has to change because of it. If you have BV please ask for the gel. It's expensive but this pill is so hard on your body, any pharmD will tell you that. Even if you aren't an extreme case, you could end up with bad side effects that aren't worth it. If you have to take this pill, make sure to listen to your body. If you aren't tolerating it, stop and call your dr before you do more harm than good”

“Had terrible smell and had discharge constantly. After the second day on antibiotics it went away! But once during the 10 day period I had sex, so please follow directions NO SEX because you will ruin the treatment and will have to start over.”

“Taking this medication really wasn’t all that bad. I’m seeing a lot of negative reviews on this, but I know everyone is different and feels different. But for me the only things I noticed while taking metronidazole, was dark brownish urine, used the #2 more frequently, which probably is okay because it could just be my body cleaning it’s self out. And I wasn’t exactly dizzy I just couldn’t concentrate too much on what I was looking at, but not to seriously. In the morning is when I’d taste a bit of that metallic taste. But those aren’t that bad of symptoms to me, because it took the odd smell away and my discharge isn’t a constant amount anymore. I used to always have to change panty liners daily and I can now just wear my underwear with out a pantyliner, and it’s not uncomfortable. So I actually appreciate my doctor for giving me this medication.”

“I’ve been on metronidazole for 3 days and I have been on it before. The reviews of this are so surprising to me because I don’t have ANY of those awful side effect symptoms. I just take it as planned and go on with my day, it worked for me”

“I'm 35 ,female, in average health and I didn't really have any bad side effects to this . It took care of the BV within a couple days !! I feel sooo much better it is WORTH IT!! mine was so bad I was in PAIN! NO More pain or smell. Amazing The only side effects I notice at all were : Headache on day two. Really bad but I am also a waitress and did a double shift that day, so it could have been that. Slight general weakness and slight mental fog Slight loss of appetite Dark urine, very dark! And that's with me drinking adequate water , I thought, so my advice is, Drink plenty of water. Eat a full meal before you take it. Cover it in peanut butter or take it FAST with orange juice because they are some nasty pills!!!”

“The bad reviews & side effects scared me. I don't need more toilet/cry time. So I did this to have 0 loose stools & barely lowered mood: -Set up your phone alarm so you don't miss a dose. -Dose at equal times apart. Your body will benefits from consistent levels of antibiotics (AB). If you dose early, you get more side effects. If you dose late, bacteria can grow back. Example: For 2 doses per day, dose 24÷(2)=12 hours apart. -Take probiotics (PB) between your AB. AB kill both good & bad bacteria. Without good bacteria, your mood worsens (look up "mood gut"). PB restores a healthy gut. I took AB twice a day; this was my alarm clock schedule: 10am-AB 4pm-PB 10pm-AB 4am-PB (I'd wake up, eat a bit, dose, then back to sleep.) -Take all your AB. Follow these tips to get less side effects. Take all your AB to save humanity from AB-resistant bacteria! -Eat some food before you take either AB or PB, to avoid upset stomach from AB & to get more benefits from the PB.”

“When I first got Metronidazole I googled it before hand (which is a common flaw of mine!) and was instantly put off by the reviews. I postponed my treatment because I was so nervous of having to work full-time and being so ill. I decided one day to just go for it and I didn’t experience any major side effects at all! I was sleepier than usual but nothing too serious. I didn’t experience any metallic taste, nausea or dizziness... I was shocked because after reading the reviews I was definitely not optimistic about taking them. On day 5 I did get a sore tongue though? Which is strange considering I didn’t have the tablet in my mouth that long on any occasion? Looking at these reviews now it seems oral thrush is a common side effect which possibly could have been what I was experiencing but it has gone away on its own and wasn’t painful or that bad at all. I know everyone is different but my treatment was a success! Good luck to you all I am sure you’ll be just fine!”

“Took metronidazole for BV and like many of you, I was horrified when I came across these reviews before taking them. I was super hesitant but I ended up taking them anyway. To my surprise, I did not experience any side effects, literally zero!!!! I am SUPER super relived and happy. I am also only 4/7 days in and no more smell/discharge! Tip: For people who cannot stand the metallic taste of the pill, put the pill as far back in your mouth as possible—and I mean really far back—and gulp down water as soon as you do. Never had an issue with the taste by doing so!”

“I bought this drug metronidazole to tackle BV, I definitely feel side effects but they are not as common, I have developed an achy throat and what feels like slightly swollen glands up to my ears and a runny nose, I’m also feeling a bit faint, however on the whole it’s nothing serious. It’s definitely a harsh drug but let it be known that it is extremely effective, at least it has been for me. My symptoms that I haven’t been able to get rid of for a long time have disappeared overnight, no more odor. Make sure to finish the course of drugs if you can because it is worth it.”

“I've had bacterial vaginitis on & off for many years and just got sick of treating it until a few days ago when I was struck with bad pelvic pain and pressure, ended up in ER and diagnosed with pelvic inflammatory disease which has caused an abscess on my left ovary. Turns out the Pelvic Inflammatory Disease has been caused by the untreated bacterial vaginitis over time. So please get treated every time you get symptoms. I'm on day 2 & have an ease of symptoms from the BV but get very nauseous and sick feeling after taking it. I'm also on a few others for the PID but it's definitely no fun. Don't ignore Bacterial Vaginitis.”

“I got prescribed 500 mg metronidazole twice a day for 7 days for BV. By day 4 had extreme nausea, dizziness, irritability, trouble falling asleep. On day 5 I woke up with awful stomach cramps got out of bed to throw up and ended up fainting. I felt mentally out of it the whole time I was on them. It cleared the infection though. Don't really want to experience this again. Also the taste is god awful.”

“Was so anxious and scared to take this medication as I read all these reviews, but I was at a loss as nothing worked to get rid of it so this was a last resort! Absolutely NO side effects just took the medication as it says to do so. Worked and done the job. Feel so relieved it has now gone. Please do as it says and you will not suffer with no side effects.”

“Took 500 mg twice a day for 2 weeks for bv, it cleared the infection but I have had major back pain and anxiety weeks after I finished the medications. It's so horrible I can't drive some days because I get dizzy. It's been a year & still get random back pain and random anxiety attacks, stay away from this medication”

“I cover my pill with peanut butter completely & then take it. That nasty taste doesn't get in your mouth. If I don't do that then I feel like I'm going to spit it right back up. Just thought I would share that.”

“I sympathize with those who had to prolong their treatment in the course of 5 days, I on the other hand and thankfully at that was prescribed only a single dose of 5 tablets of Metronidazole. Quick and easy. Make sure you eat before you take it though and I find if you hydrate yourself you less likely to feel nauseous. I've had recurrent bacterial vaginitis so I know what I'm talking about.”

“I was suffering symptoms of BV for more than 6 months. It was making me so self conscious, I started avoiding sex and constantly has to wear panty liners because of the discharge. I finally went to the GP about it two days ago and he prescribed me Metronidazole. So far the discharge seems to have stopped and it's the first day in what feel like forever I have been able to not wear a pantyliner, odour seems to have gone already as well. It's not until this has started to clear up that I have realised how much its was dragging me down!”

“Okay so before I took this I read all the reviews on here. I was frightened. So I began a 7 day process, 2 pills a day. The odor went away the 2nd day. I guess it started smelling normal. I was very pleased it didn't have that fishy smell anymore. However I still discharged and on the last day I discharged so much! The doctor and nurse said it's just cleaning everything out. Overall I was pleased. The effects I did have were diziness, headaches, abdominal pain, and somewhat nauseous. What was weird was that one day my mouth tasted what it smelled like. It smelled and tasted in my mouth like a little bit of bleach. Oh and the pills aren't that bad tasting when you get used to it.”

“I was prescribed the 500mg x 4, taking all pills at once treatment. Became incredibly nauseous after a few hours, dizzy, dry eyes, a bad headache. Started feeling dissociative suddenly. Eventually started to become very anxious, evolved into a severe panic attack where I could not land for hours. Reached a point where I really thought I was losing it and contemplated calling for health professionals, until someone came to me and could help calm me down. But I still felt a complete loss of reality and rationality, and I have never experienced this much lack of control before. It did better the symptoms for the bacterial vaginitis but in the future I would rather do any other treatment than this.”
