FLAGYL  (METRONIDAZOLE):  Metronidazole is an antibiotic that is used to treat a wide variety of infections. It works by stopping the growth of certain bacteria and parasites. This antibiotic treats only certain bacterial and parasitic infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections. Metronidazole may also be used with other medications to treat certain stomach/intestinal ulcers caused by a bacteria (H. pylori).    (Sources: U.S. Centers for Medicare Services, FDA)

 1  BV frequent bowel movements that turned into diarrhea (not watery), constant full feeling with a "bloated" stomach (even after bowel movements (which are up to at least 4x a day, usually only have them once a day), great fatigue, loss of appetite(feel like after i take my last pill i wont want to eat for a few days), terrible metallic taste (especially laying down), unusual digestive activity and slight cramps in the abdomen I hate feeling nauseated so I eat a small snack with flagyl, which keeps me from becoming nauseated but is a catalyst to my constant full feeling and large stomach (i think someone said they lost weight in this forum, i wish!). My stomach hangs over terribly and i dread taking the pill, there has to be an easier way, with such a high dosage im taking and how frequently i take it..i dont even eat 4x a day! I eat once! or maybe 2x! so this is too much.i'm always lethargic, and slow-to-draw getting out of bed, i thought it was my new job and new hrs so i went running and exercising (esp to lose this gut) only to find out the gut is not leaving so long as I take this med and I am just 2x as tired after exercising where normally I feel refreshed.the stomach activity is annoying, i feel like i have gas but nothing comes out. The most annoying parts are the persistent full feeling along with the atrocious metallic taste (which initially, i thought my water plumbing was bad suddenly and wanted to call maintenance on my apt). Water is disgusting, i feel like a pig eating, i'm tired all the time, my stomach cramps and hurts and is excessively large, and the metallic taste is thoroughly unbearable. This product should be off the market, and i dont think any medication in such large dosage amts should be taken for 10days! Reading this website, i only saw 2 others who took flagyl for 10 days and only one other person was on the same dosage i am. Never again. NOT RECOMMENDED F 23 10 days

 1  Diverticulitis (recurrent) Each time I have been prescribed the combination of Cipro and Flagyl, I have experienced progressively more severe side effects, The first few days are not so bad; however, the longer on the combo the worse the symptoms, which are, extreme cramping (on a par with labor pains), inflammation of the whole lower abdominal region, feeling as though my colon received a caustic burn, itching in my ears, fatigue, and mental confusion. I have told my doctor EVERY TIME she wants to prescribe it, but my pleas have fallen on deaf ears. Apparently it's the preferred treatment. I am not one to exaggerate and maybe her other patients do. This drug combination made me feel as though my colon was going to rupture and I would die. I could hardly walk, I felt as though I was carrying 9'lb bowling ball in my pelvis. My uterus felt like it was being expelled through my vagina due to the pelvic pressure. My bladder felt battered and I had to urinate every 20 mins to an hour because I couldn't stand This drug should not be dispensed without a thorough patient understanding of the potential side effects. My mother also had severe side effects. F 49 10 days

 3  IPAA, j-pouch surgery Extreme fatigue, tiredness, nausea, irritability, muscle aches, metallic taste, brown urine, dizziness, lethargy etc. I hope Flagyl is the cause of these side effects, otherwise I am in real trouble. I had my colon removed in February and IPAA in mid March. Longer, harder recovery than I had anticipated. Taking cipro/flagyl combo off and on since November. I hope this exhaustion goes away when I stop flagyl this Thursday. M 35 1.5 months

 5  Acute diverticulitis Insomnia; but I realized I was taking the medication too close to bedtime and simply adjusted the routine. Yup; I've been on it many times in the past 10 years, along (usually) with Cipro 500 mg. twice a day also. The combination works well for me when I need it, and I need these medications much less often now that I've had a left hemicolectemy. DO NOT take both meds at the same time; separate them by at least 1/2 an hour and you may have fewer problems (if you do have any). My pharmacy clearly labels the Flagyl with a warning not to take with other medication unless directed by your doctor. The only problem I have with these two meds is some insomnia and I altered the dose time and resolved that issue, making sure my second dose in the day was not so late at night as I had been taking it. I'm going to post this same verbiage on the rating page for Cipro. Do be sure to drink a full glass of water with each pill. F 69 10 years

 1  BV The first side effect I experienced was loose stools. After that passed, my guts felt bloated and active. I felt like I was in a cloud, totally out of it. On my daily walk, my legs felt heavy and I felt very lethargic. My speech didn't feel 100% and I mixed up a few consonants here and there, at which point I googled for info and found this site. After my routine GYN appointment, my dr called to say I had an overgrowth of bacteria and suggested I take this medicine. I didn't have any symptoms whatsoever. I joked that it would be hard to take because of my daily wine consumption. At first I thought the symptoms were related to alcohol withdrawal and dismissed it. But my research on alcohol withdrawal didn't describe anything like I started feeling on Day 2. While the symptoms are tolerable, what concerns me is what is coming... the anxiety, depression, insomnia, nightmares, dark urine, nerve tingling, etc. It doesn't seem right that a drug should affect the whole body like that. For me, who had no apparent BV symptoms, it was hard to justify continuing it. Also, reading that the BV has a high probability of returning once meds are done also didn't sound right to me. I googled homeopathic remedies for this situation since it seemed to me that I'm suffering a mild bacterial imbalance that is probably diet related. Which means it'd likely come back once this drug is done. There is a lot of very good information and tips out there about how to manage this without drugs -- it just seems to make a whole lot more sense. I am stopping this drug immediately (wish I could throw up the one I took a few hours ago). Will be trying it out. F 38 1.5 days

 4  BV Almost constant headache that seemed to surround my eyes and go to the back of my neck. On day 5 I started feeling some stiffness in my back. Some stomache discomfort but not too bad. I'm usually an ibuprofin fan but tylenol seems to help my headache from this better. I started getting concerned of my headache lasting so long but I'm very relieved to know that it is fairly common.

 1  BV Severe and persistent headache, eye pain, sore throat, constant drowsiness, irritability While discussing my side effects (deemed severe and with urgent action required by the pharmacy) with my physician's staff over the weekend, they were unaware and skeptical of the side effects discussed on the FDA site, which included serious affects such as asceptic meningitis. I am presently 10 weeks pregnant and also learned that this drug should never be prescribed in the first trimester. I have stopped taking this medication immediately and due to the combination of the side effects, public information from the FDA, and my physician's staff's response, I will likely change doctors as well. I urge anyone who has severe side effects to read the precautions listed on the FDA site to better understand the risks of this medication. F 30 4 days

 1  diverticulitis began taking on a Saturday afternoon, that night my nose felt swollen & stuffy, Sunday my tounge felt as if it had a hair on it, Monday my face and tounge began to tingle, Tuesday thursh developed and tounge began to feel swollen, Wednesday morning my mouth & tounge was numb. It is hard to swallow & no taste on the front & middle part of the tounge. lower lip was bitten badly and I can not chew food. My mouth feels numb as if I have been to the dentist and had a filling. my whole face & part of the side of my head got numb. I spent 12 days in the hospital due to these symptoms and had several tests, MRIs, blood work, spinal tap, and a biopsy of my colon and every test that has been done so far has came back normal, I kept telling every doctor I have seen I was perfectly fine until I started taking the flagyl and they said it has never done anyone like this. I just got back from a follow-up appointment & was told all tests were normal & it could have been the medicine that has left me like this. The doctor has ordered more tests and blood work. It has been almost two months and my mouth is still numb. I just hope and pray that the numbness goes away so I can eat normally again and not have to have my food blended or liquids thickened. I feel for the girl who had to have a feeding tube, they were considering that for me at one point in the hospital. THIS IS MISERABLE! F 74 4 days

 1  H. Pylori STRONG metallic or aspirin like taste in my mouth, nausea, dizziness, light headed, thick coating on my tongue, weepy. I was prescribed this drug along with clarithromyacin for H. Pylori. After my first dose, I woke with the worst taste in my mouth. It tasted like I had chewed a handful of aspirin and didn't swallow it. I couldn't believe it. The next day, my mouth felt so gross...the same feeling after eating way too many sunflower seeds...raw and sore. Chewing gum has helped, but I could only do that so much before my jaw started to hurt. The first couple days of treatment, the antibiotic seemed to be fighting with the bacteria and it was VERY PAINFUL...and I was very nauseous from this medication. After a couple of days, the symptoms of the peptic ulcer started to subside, but since then, I've had to deal with the side effects of the medication instead...and I'm not sure which one was worse!! I am on day 12 of a 14 day treatment and was told by the doctor (after I called to complain about the side effects) that I could stop the treatment after 10 days. But I decided that having to start over with the meds (if it didn't kill the bacteria) was much worse than going two more days...so I'll suffer through it. I've come this far....why not???!?!??

 5  Parasites Debilitating nausea, dizziness, headfog, dark brown urine, complete loss of appetite, couldn't get comfortable, headaches, vomiting, chills, night sweats. I was diagnosed with parasites 6 months ago, and a low dose of Flagyl killed giardia but not the a.hartmanni. No side effects with the low dose. However, GI recommended Flagyl 9 pills/day for 10 days. I was immobile and non-functional for the entire 10 days. It was the worst experience i wish on no one. I could not leave my bed due to the unbearable nausea, headaches, and dizziness. My friend brought some homeopathic "ipecacuanha" and i took that every 2 hours, and by the 2nd day of taking it my nausea was bearable. Highly recommend it, but it takes a few days to get into blood stream. Since i was having diarrhea for 6 months, i had to give this a try despite feeling like hell. It's been a week now since i've stopped the meds (still some side effects), but I'm so happy that my diarrhea has stopped! I just could not believe it, it actually worked. Now i'm repairing my system with probiotics and milk thistle (for liver toxicity). I never want to take this high dose ever again, but i'm glad i did it and glad it's OVER!! M 46 10 days

 5  diverticulitis I am praying that I don't experience any side effects - so far, so good. I have upped my dosage of xanax prophylacticly to avoid anxiety attacks. My DV pain is already better after 2 doses. I wonder if a lot of these side effects aren't from Cipro, which has been a very difficult drug for me to take in the past, and caused me many of the side effects mentioned here. I typically have the worst possible reactions imaginable to medications. You can imagine how concerned I am. Praying to be able to take this drug, because nothing else is helping the DV. F 51 1 days

 1  Peri-rectal abcess Horrible taste in mouth, nausa, sharp kidney pains, cotton mouth, loss of appetite, brain fog, lathargic, sleepless, can't get comfortable.... ever!, dizzy on occasion, yeast infection. I was diagnoses with colitis and hemmoroids initally and then found out I had a large abcess around the rectal area, which was the problem all along. I took cipro and flagyl together for the colitis and when my rectal pain came back (the doctor originally thought it was hemmoroids.... wrong!) I had a ct scan and the horrible abcess was located. Now I'm back on Flagyl, but this time combined with levaquin. I have to get the abcess drained this week, but in the mean time i'm on the antibiotics. don't get me wrong the abcess pain goes away with this horrible antibiotic, but Flagyl is pure poison. I wouldn't wish this drug on my worse enemy. I have taken levequin by itself with no problems. It's so bad that i think if i get sick again i might lie to the doctor and say i'm allergic to this drug. F 28 7 days

 2  post root canal problems Dark brown urine, blurry vision at times, pins and needles in fingers, dry mouth, metallic taste in my mouth, foul smelling diareahh and nausea. I am on day 7 of taking flagyl and have experienced these symptoms since day 1. I don't believe I even had an infection after my root canal (was prescribed amoxycillin 200mg 7 days also), I just think I should have went to an endodontist in the first instance instead of regular dentist. I still have pain in my mouth with all these other symptoms to boot now. I wouldn't say not to take this drug, but be aware that it is a hardcore drug, but that may be what your system needs. I have managed to function normally at work (full time) and drive. I experienced blurred vision while driving but not enough so that I couldn't see, it was just uncomfortable. My only complaint at work was cotton mouth and the occasional trip to the toilet. I will be glad when this treatment is over though. F 35 7 days

 1  clostridium difficele Nausea, severe heatburn, severe fatigue, abdominal distention, backache, appetite changes, intermittent anxiety, poor sleep due to side effects making me feel so ill in addition to unusual anxiety, liver function tests (ALT, AST, alkaline phosphatase) elevated out of normal range. My alkaline phosphatase was so elevated (249 with normal range of 40-150) that my MD ordered an abdominal ultrasound as he suspected liver or gallbaldder disease. My ultrasound was normal and it was determined that elevated levels were due to the metronidazole (flagyl). That is how hard the drug was on my system. I made it thorugh day 8 of 10 day course and returned to the doctor because of how bad the combined side effects were making me feel. He took me off of the metronidazole. The c. diff diarrhea returned and I was placed on oral vancomycin. Day 8 of the vanco. I feel much better as the vanco has not given me any side effects to speak of. After stopping the metronidazole I was searching the web for side effects of the drug and came across this website. I was stunned to see how many people had the same or a very similar group of side effects, particularly several that mentioned the anxiety. I think the doctor did not believe me that I felt the drug was causing the anxiety spells. I honestly felt as if I were poisoning myself the more doses I forced myself to take. This drug may work but for at least a very significant portion of patients it has very, very harsh side effects. F 54 8 days
