For Dental Abscess "I am taking this med for a left molar abscess, I was informed by the dentist that I have two. It is working on the abscess and me. I feel sickly, and I have been nauseated and vomited once. I have been taking this for 3 days now, with 2 more remaining. I will finish this medicine, but after this, I refuse to take this abt again. I am also taking amoxicillin along with this med, I have taken amoxicillin many times, no issue with it."

For Bacterial Infection "I have been prescribed Flagyl (metronidazole) 500 mg twice a day for 14 days for a colon infection and have to say that it's terrible! I've been on it for only two days and the migraine is unbearable, the nasty metallic taste gross, and the nausea and vomiting are bad, but it is way better than the ciprofloxacin that gave me bad depression and the feeling I was dying. 13 days more to go and I can't wait to be off this medicine."

For Bacterial Infection "DO NOT TAKE FLAGYL EVER. TAKE ALTERNATIVE DRUG. I am 19 years old and extremely healthy and active with no health issues or problems. A doctor had me taking metronidazole for 2 weeks. I was taking this medicine based off of a diagnosis that was false, but that’s besides the point. By the end of week 1, I was on my way out, and I don’t mean figuratively, I mean literally. I was experiencing tingling in my fingers and toes, a cold sensation, and my fingertips and toes turned blue. I threw up every 15 minutes for 3 days. My pee was a dark opaque brown color. My liver and kidney functions started to decrease, as well as my blood pressure. I was EXTREMELY lethargic, confused, dizzy, and my eyes were very sensitive to light. I lost 10 pounds that I couldn’t afford (100 pounds even now). I visited the EMERGENCY room three times due to the adverse side effects before they decided to take me off the medication that I didn’t need anyways. Read up on other reviews, people aren’t lying, this is a nasty drug."

For Bacterial Infection "I'm even struggling to write this because of how unwell I am after taking this two days ago now. Since taking these tablets with food, BV has gone, but I feel like I'm gonna throw up 24 hours a day, sleeping all the time. I have taken these tablets before, but never have the side effects been this bad. I would rather have the BV back rather than go through this, sighhh."

Metronidazole for Diverticulitis "I was prescribed this for a diverticulitis flare-up. After the second day, all hell broke loose. Felt faint and sick with diarrhea and vomiting. Couldn't eat anything and ended up in the ER. Was told to stop taking it and see my gastroenterologist. It takes 48 hours to get out of your system, and I can barely move off the couch without passing out. Run far away if prescribed this. And research the permanent damage it can cause. Scary."

For Bacterial Vaginosis "My infection cleared up by the second day I was using it, but I was given a prescription for 500 mg twice a day for seven days. The side effects have been bad. I have a headache, I vomit everything I swallow, and can barely get out of bed."

For Diverticulitis "I was diagnosed with diverticulitis. Currently on my 5th day. The positive side is I am actually feeling better, far better, but side effects are hitting hard: diarrhea, heartburn, upset stomach, zero appetite, and the urge to vomit. There are still a few days to go. I will keep going since it's for my good."

For Bacterial Vaginosis "I had no symptoms of BV but was diagnosed after a pap and was given the pill for 2 pills a day for 7 days. The side effects have been absolutely awful. I went home from work on day two thinking I had the stomach flu (nausea, vomiting, diarrhea, fever, sweating). I finally realized it was the pills. I've also experienced trembling hands, night sweats, dry mouth, fatigue, loss of appetite (which is weird because I'm PMSing and usually starving at this time!), mood swings, and increased anxiety. I don't find the taste of the actual pill to be as unbearable as everyone says, but it does leave that metallic taste in my mouth. I'm on day 4 and don't even know if I want to take the pill before work this morning!"

For Helicobacter Pylori Infection "I was given 500 mg four times a day for H. pylori. The taste was horrible, and by day 5, I started to vomit. I called my doctor, who refused to return my call. By day 6, I started having stools like water. I stopped the drug on my own. I'll be careful what I take next time."

For Trichomoniasis "Found out I had Trich and BV on Thursday and was prescribed 500 mg pills. Have to take one pill twice daily. I absolutely hate this medication. I have terrible stomach pain, nausea, and vomiting. On the second day of taking it, my legs felt numb and tingling. I could barely stand...I had horrible anxiety and just wanted to jump out of my body. I’m in a committed relationship with my partner, he had this before I met him, but I just want to break up with him because of how horrible I feel. This is going to be the longest week of my life."

For Bacterial Infection "I was given metronidazole for my tooth infection for 4 days, took 3 x a day. Over the 1st 24 hours, I have reacted badly: vomiting, headache, and up all night. Waiting on the dentist to open, cannot stand the headache and the pounding heart rate. Worse than the actual tooth infection. Be warned when taking this. Prepare for a reaction."

Metronidazole for Bacterial Infection "For the last few years, I have had recurrences, sometimes as often as once a week of vomiting and diarrhea. It seemed to be traced to exhaustion and fatty foods. In the meantime, my wife contacted C. difficile in the hospital. Along the way, I may have contracted C. difficile too. In any event, my doctor prescribed Flagyl, which I took four times a day for 10 days. This cleared everything up, but the problem kept occurring. For the last 45 days, I have been taking 2, 250 mg capsules once a day. Recently, I have cut down to one. Although I have had occasional diarrhea, there has been no vomiting or nausea."

For Amebiasis "Worst medication I have ever had. I started off vomiting once a day, then twice a day. My hands were tingly, and my feet. My scalp went tingly too. I felt so dizzy and thought I was going to pass out. This was just awful. At first, I thought this might have been symptoms of amoeba, but it was from the antibiotic - metronidazole is a powerful drug. Unfortunately, I had all these symptoms on an island and had to return to the mainland. The more competent doctor on the mainland stopped the flagyl and prescribed dioxanide furoate. Metronidazole is used to treat the parasite, however there are also eggs associated with the parasite, and they will hatch as well. Metronidazole treats the parasite, diox treats the eggs. These will show in stool separately."

For Bacterial Vaginosis "No side effects. Here’s how I did it: I ate about an hour before, then at the time of taking the pill, I took it with a big gulp of ginger ale (even though I don’t normally drink soda). I did this because I read that the pill tastes horrible. I am on my last day of pills, and I haven’t tasted a thing since I started. Although I was prescribed this medicine without ever having symptoms of BV, I truly don’t think this medication is all that bad. Please take comfort knowing that you will be fine. Just make sure you eat a bit before, have a cracker after, and just continue on your way. You can also add a probiotic into your routine, which I did in between taking the 2 pills a day. Just don’t freak yourself out about the nausea and vomiting like I did! Oh, and I also didn’t feel “out of it” or dizzy like some other reviews. Ultimately, everyone is different, so try it for a day and see how you feel. I just want to give you guys some hope :)"

For Diverticulitis "In haste, I took my Flagyl/Cipro at bedtime, thinking it hadn’t been that long since I ate. I also took a pain pill. Well, within an hour, I was vomiting and wishing I was dying. It was awful! I have had diverticulitis several times and am usually hospitalized. So, trying to treat at home. I was sick up until about 3 p.m. today, vomiting and dry heaving. Zofran didn’t stay down, finally, Phenergan did. What a wasted day with debilitating nausea. Maybe I need to try the Zofran that dissolves in your mouth and works immediately."

For Bacterial Infection "Hated this drug! Vomiting, diarrhea, can't eat, dizzy all the time, even a year later, severe anxiety, panic, depression, muscle weakness, heart palpitations. This drug ruined my life along with Cipro! But a year ago, I took only the Flagyl with Bactrim, no Cipro, and it has done me in. I feel I'll never be the same. DON'T TAKE THIS DRUG!!!! My whole life I was active, strong, happy, very social, now I don't want to leave my house unless I have to. Never had anxiety or depression, never, until Flagyl, it did something to my brain. Now I have to use a brain stimulator to help with the depression and anxiety because I WON'T take drugs!!!!"

For Bacterial Infection "I took 500 mg metronidazole, 3 times a day for 10 days, a total of 30 pills to treat IBS-D (diarrhea), SIBO (small intestinal bacterial overgrowth), and a possible parasite. Almost every day I had mild nausea, bloating, dizziness, fatigue, frequent urgent stools, dry mouth, and headaches (it could have also been from my anxiety about taking it). I had violent vomiting after the 4th pill and diarrhea after the 15th pill. My doctor then told me to reduce the dose to twice a day instead of three times a day, and I felt a lot better and was able to finish the dose. You must take it after a full meal to avoid nausea. I coated the pill in molasses and drank it with milk to mask the taste. I was so nervous to take it after the horrible reviews I read, but it was manageable, it just felt like I had a cold/flu for 2 weeks. However, I would not take it again, it didn’t work for me in the long run."

For Bacterial Infection "I found that this medication made a HUGE difference within even the first day of taking it, however, the nasty bitter taste was really hard to get by, and I even threw up once when I was trying to take it. BUT I discovered taking the pill with milk masks the nasty taste. I now put the pill on the back of my tongue and swallow it down with water. Try it, I guarantee it will help."

Metronidazole for Bacterial Infection "I have experience with a lot of other antibiotics, but this one has been by far the worst. The taste is so bad I threw up one of my doses, and the taste doesn’t wash away with water, it lingers. It helped with the infection, but it also wiped out all the good bacteria in my gut. This isn’t unheard of from antibiotics, so I’d supplement with probiotics as well. Food doesn’t sit in my body for longer than 10 minutes, and the lack of food is giving me bad headaches, and my body is so tired."

For Bacterial Infection "I'm 20. I had to take Flagyl 500 mg for 10 days, twice a day, every 12 hours. (Total of 10 pills) For BV and cervix inflammation. I started taking the pills on October 2nd and ended on October 12th. I didn't notice any side effects until after I stopped taking it. I had very bad nausea on October 15th. I was vomiting up water, and I tried to drink a strawberry lemonade from Wendy's and threw it up. The nausea lasted a day, then the next day, I had diarrhea that also lasted a day. I'll admit it really does clear your infection within the first three days, but I had itching and developed a yeast infection, which I was told about before buying the prescription. The pill tastes nasty. Take it with milk or anything other than water because the pill will get powdery, like chewing an aspirin."

For Trichomoniasis "Took 1 tablet by mouth twice a day, and it was prescribed for 7 days. Experienced multiple side effects such as vomiting constantly, headache, nausea, and dizziness. I couldn't handle it anymore, so I stopped on the second day. Didn't work for me."

For Bacterial Vaginosis "I was prescribed the 500 mg three times a day for seven days, and the side effects are horrible! My infection did clear up by the second day, which is great. But the side effects make me not want to take it. By the second day, I was very nauseous, had really bad headaches, felt weak, my heart races, and so I can't sleep at night, hot flashes. On the third day, I vomited all morning, and I got so dizzy. The taste is gross, but it's fine with a glass of milk. I'm taking Advil for the headaches."

Metronidazole for Bacterial Infection "I am taking this alongside Amoxicillin prescribed by the dentist for gum infection. Never had problems with Amoxicillin. I’m into the third day, and I am feeling sick. Woke up in the middle of the night, vomiting, and my limbs were in pain. Never have I experienced side effects of a drug this severe. It has helped, though, as the swelling and pain in my gums have gone."

For Helicobacter Pylori Infection "Metronidazole should be removed completely from the list of antibiotics. I was diagnosed with H. pylori, and I hate how this particular antibiotic makes me feel. The doctor said to take it with food, but how when this disgusting pill makes you lose your appetite? And when you do take it with food, you get nauseated. I threw up and felt weak... REMOVE METRONIDAZOLE, IT'S NO GOOD."

For Bacterial Infection "Had to take this for an infection where my wisdom is coming through. It got rid of the swelling, but I couldn't finish the course. I was throwing up a lot, couldn't even keep water down. Got terrible diarrhea with it as well and was constantly tired. The stomach ache that kept going from a stabbing to an aching pain and constantly lingered just made me irritable, although irritability is also another symptom. All around terrible to take."
