Flagyl (metronidazole) for Bacterial Infection "I really don't understand all the negative reviews for this medicine. I've been on it for three solid days now and have had absolutely no issues. I'm taking 500 mg, one pill twice a day. I've been taking it after lunch and dinner and haven't had any issues with diarrhea, nausea, or dizziness. As for people complaining about the taste of the pill, how are you even able to know what it tastes like? It should be in your mouth for less than a second, just swallow it down with a glass of water or some orange juice."

Flagyl (metronidazole) for Bacterial Infection "Went in for my Pap smear and found out I had BV. I was prescribed Flagyl (1 tablet 2x a day). The first day I only took one pill during my lunch break but forgot to take the second that night. The next day I took two pills as prescribed (morning and night). The following morning I noticed dark urine... allegedly that's a 'rare' side effect. I’ve also experienced dry mouth, a metallic aftertaste, headaches, and loss of appetite. Other than that, I do see an improvement already. I’m glad these pills work quickly, just hoping I won’t have to take it ever again after the 7th day."

For Dental Abscess "I've had a dental abscess on the lower left side for 1 1/2 weeks. Because of coronavirus, all dentists are closed, so a phone consultation was all I could have. I was prescribed a 5-day course of 500 mg amoxicillin, which started to clear it, but as soon as the meds were finished, the infection came back the following Sunday. On Monday (yesterday), I again spoke to the dentist, who prescribed another 5-day course of 500 mg amoxicillin. By the evening, the left side of my face was really swollen. I couldn't sleep, and this morning the swelling is huge and feels solid, like I have a tennis ball between my gum and cheek. I phoned the dentist again and spoke to a different dentist who has now prescribed metronidazole alongside amoxicillin. I've read the reviews, and most of them are describing how I feel now because of the infection, not because of the meds. I know everyone is different, but if you have a severe infection, the only thing you can do until dentists reopen is take the meds and pray the pain and swelling go away."

For Bacterial Infection "With all the negative reviews I felt compelled to share my positive experience. After suffering horrendously from a tooth abscess for an entire month with 2 rounds of Amoxicillin, my dentist prescribed me Metronidazole dose of 400mg, 3x's per day, for 5 days. The first day I felt very tired taking this medication. Morning were the worst as I felt like I had been hit by a truck- very blah/tired/groggy. I hesitated taking this medicine for the first couple of days because of this, but I powered through and still took my prescribed doses. I never had any stomach problems, headaches or any other side effects. Then, on the 3rd day, I woke up and my pain was almost completely gone and the swelling was significantly down. This medication is no joke. A week later and my abscess is completely gone now. It may make you feel strange/tired/hungover but it absolutely worked for me. I will gladly trade the feeling of being groggy over the pain of an abscess any day! I recommend giving it a try!"

Flagyl (metronidazole) for Diverticulitis "Taking the antibiotic combo metronidazole and Cipro for a flare-up of diverticulitis and now on day 4. My side effects are that I feel so dreadful, very weak, no appetite at all, dizzy, nauseated, night sweats, vaginal discharge, diarrhea, and I have lost 7 lbs already. Forcing small bits of food down as I have to eat something, drinking lots of water, feel nauseated. I am in the UK. This medicine is utterly brutal and toxic, but my pain is nearly gone. Longing for day 7 to end the drama."

For Bacterial Vaginosis "Had a 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."

Flagyl (metronidazole) for Diverticulitis "Was given this for diverticulitis and after day 3 of taking woke up in a cold sweat, hair soaking wet and feeling faint. Slurred speech and overall feeling of dying! Went back to ER and they said it was side effect of this medication. They told me to continue no matter what, told them I'd rather die and threw the medication away. I'm still alive and doing well without this nasty medicine!"

For Diverticulitis "I have had my first bout of diverticulitis. I was prescribed Flagyl and Cipro. The first day I took them together, I got a massive headache and felt awful. On the second day, I did this: Cipro at 6 a.m. on an empty stomach with 500 ml of water. I had coffee an hour later. At 8 a.m., I took Flagyl with a glass of milk (I can't take Cipro with milk because it has calcium, but you can take Flagyl with milk) or applesauce. I have no bad taste with milk. Then I repeated this at 6 p.m. with Cipro and 500 ml of water, and at 8 p.m. with Flagyl and milk, and that's it. I get no headache, no nausea, no vomiting, nothing, and I am slowly getting better. I think taking Cipro and Flagyl together causes a reaction and gut issues, so it is best to separate them out, let them work separately, and not mix the medications together. Also, Flagyl is an antiparasitic, so it might be causing a bit of Herxheimer reaction after a few days."

For Dental Abscess "After reading some of these comments, I really did not want to take this medication. However, after taking it, my abscess and swollen face has almost cleared, and I am out of pain. I took this alongside amoxicillin, and it has worked absolute wonders with absolutely no side effects whatsoever. Some people may react differently, however. But it was an absolute lifesaver for me; it’s the first time I’ve ever had an abscess, and the pain was horrendous. Kind regards, Maria."

For Diverticulitis "Diagnosed with diverticulitis and put on Cipro and Flagyl , today is Day #10 hallelujah!! Had diverticulitis flareups 4 & 5 years ago. I forgot how sick these drugs make me. I can’t keep food down, nauseous 24 hours a day except when I take Zofran, upper stomach pains, reflux, heartburn, dizziness, listless and spend most of my day sleeping. This came at the most inopportune time I just had major knee surgery two weeks before the attack which has hindered my healing process as I can’t get up to proceed with physical therapy, it’s too nauseating to move around. If I ever get another attack I will never take these drugs again. There has to be a better way! I want my life back "

For Trichomoniasis "I have trich and I was put on the 4 pills at once of 500mg. I took it Thursday at noon. I was fine. I have to say the taste is not the best. Put it way back on your tongue, drink water, and swallow. Don't start smacking your tongue around, that's what makes you taste it. So I took it, went to work, and around 9 I got nauseous. It came and went. At 11:30 at night, I was very nauseous, I just went to sleep. The next day I noticed a lot less itch and burn. Absolutely no more nausea. Today, Saturday is day two, I feel good. Again, I'm not 100% clear because occasionally I feel a little itch, but I like this pill. Also, on day one on the pill, I had a one-time heavy discharge. It was like the infection came out. For those who ask, if you get the one-time four pills of 500mg, you must take all four at once. Trust me, you'll be okay."

For Dental Abscess "I have used metronidazole many times now, most recently for a tooth abscess, and I have always been perfectly fine with no side effects whatsoever. After the first 24 hours of taking metronidazole, my pain was already considerably less, it really works, so please don’t be scared to take it if you haven’t before, as not everyone will experience bad side effects. Take this medication after a meal and a full glass of water. I also make sure I stay hydrated and eat well while on it."

Flagyl (metronidazole) for Bacterial Infection "Flagyl antibiotic sent me to the psych hospital! Within 24 hours of taking flagyl, I was having side effects of being super drowsy, couldn't eat, having panic attacks, hallucinations, and so depressed I couldn't even get out of bed. I was also really confused and just out of it. I went to the psych hospital where they made me finish the course and it took WEEKS before I felt okay mentally. In its defence it got rid of the BV. Flagyl is one of the most powerful and potent antibiotics out there and I would only recommend it if you really need it."

Flagyl (metronidazole) for Bacterial Infection "I’m on day 4 of a 7 day treatment for BV (bacterial vaginitis) with Flagyl. I feel amazing. I was warned by my my doctor and pharmacist of alcohol and side effects. On my 2nd pill I did get abdominal pain and minimal diarrhea but that was it. I expected it to continue but so far I feel better than ever. I feel like it helped me in so many other ways than just BV treatment. I feel healthy and awake. All meds have side effects some worse than others and some experience more than others. My experience so far has been great."

Flagyl (metronidazole) for Bacterial Infection "I almost think it’s better for people to read this IF they also had a bad reaction and don’t want to feel so alone, because I have heard of this working really well for some people, as with any drug. It seems to me that if you do have a bad experience with this, it isn’t mild, but extreme, as was the case for me. I don’t do well on many antibiotics, but this one was in a class of its own for me. It took me over three months to feel somewhat normal again. It went from bad hives, to feeling like my joints were trying to leave my body, to feeling incredibly dizzy and nauseous, to stomach pain. It sounds dramatic, but I have never felt worse on any antibiotic. What it was prescribed for was so much easier to handle than the side effects of this train wreck. Every inch of my body felt off on this medicine. Even mentally, it gave me anxiety. The only antibiotic that came close to this one as far as feeling horrible is Cipro."

For Trichomoniasis "I was prescribed the 2000mg one-time dosage. 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 headache. 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!"

For Diverticulitis "My Dr prescribed metronidazole and Cipro for diverticulitis. I have been taking them for 9 days and have been extremely tired and fatigued, bouts of diarrhea and I basically head to the bathroom within a few mins of eating anything. I am on a pro-biotic and eating Activa yogurt to help with the stomach issues. I also started having severe upper abdominal and back pain. A weird sensation. I did not know what was causing this, but read on this site where a few other folks had the same problems. UGH !! I'm still having some very low tenderness in my low colon area, but I think the constant bathroom trips are possibly causing this problem. I guess I should go back to the DR, but do not want to. I'm really concerned about the upper abdominal and back pain. It is fairly constant and feels tender to the touch. Good luck out there folks ! Diverticulitis is no fun."

For Trichomoniasis "I had to take a one-time dose of 4 500mg capsules. About two hours after taking the dose, I 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. It's been 3 days since I've taken this medication, and I still have minor side effects lingering. I have been having great sleep, random nausea, vivid dreams, and random bouts of fatigue. ALL of my symptoms from trichomoniasis have disappeared, so I would recommend this medication."

Flagyl (metronidazole) for Dental Abscess "This medication could have saved my life! I had a root canal gone awry. The emergency dentist prescribed Clindamycin and Flagyl stat. Could not take the Flagyl as I had swallowed Listerine (has alcohol in it). The next morning an Endodontist redid the root canal, and he said to take the Clindamycin only. Two days - and a LOT more pain and swelling later - I found myself at night with enormous swelling spreading to my upper mouth with more throbbing pain. With nothing to lose, I took one dose (500mg) of Flagyl. Within 2 hours I felt no pain - it was like someone took water out of a balloon. Thank goodness, I believe I had an odd bacterial infection. I'll take both antibiotics for the duration. No alcohol on Flagyl - bad side effects!"
