Reviews for Flagyl

“Was prescribed flagyl for possible diverticulitis, took it for two days and could not take it anymore. It caused me to have severe diarrhea, fever, severe flu like symptoms, made me very weak, had to stop taking it. Will never take it again.”

“Having nausea everyday about 3 hours after taking Flagyl, also started feeling cramps in both calves on day 3. Only have 1 1/2 days left! Will be taking probiotics and eating yogurt as was suggested by someone in this comment stream!”

“Please DO NOT take Flagyl. This is a lethal drug that will mess your body up for months. I was given this for diverticulitis. I was asked to take Flagyl for 7 days. By day 2 I was already in pain with side effects with bad muscle cramps especially my legs. I kept going not realizing the damage it was doing. On day 6 I gave up. The side effects were unbearable. I was taking regular pro-biotics during this period and after. Flagyl wiped my gut clean to the extreme that I kept getting urine Infections / Cystitis (inflammation of the bladder) for weeks after. The constant urine infections / Cystitis continued for the next 5 months. Eventually when I saw my naturopath, he gave me a special blend of flora (pro-biotics) to help restore my gut back to normal. I don't know why doctors are allowed to prescribe this drug as it should be banned.Please avoid taking this drug.”

“Flagyl side effects are dreadful. The worst was a sudden rise in my blood pressure (BP) to over 200. Dangerous for me, loads of treatment to get it down, no more flagyl for me. Bowel was no better.”

“Flagyl cured my diverticulitis however, my blood pressure went to 200 over 119. I had to be rushed to the emergency room. Afterwards, I checked and saw that this can happen if you are in your 60's or older. Don't exactly know why older people can get this symptom, but I will never use it again. The drug worked, that is why I rated it high, but the side effects are brutal.”

“Taking the anitbiotic 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, have lost 7 lbs already. Forcing small bits of food down as have to eat something, drinking lots of water, feel nauseated+++. I am in UK. This medicine is utterly brutal and toxic, but my pain is nearly gone. Longing for day 7 to end drama.”

“First diverticulitis (DVT) attack, was in such pain & had been in a very stressful situation. I had CT and diagnosed with DVT and prescribed flagyl & cipro. Became very ill, nauseated, headache, confused, lost my way back to husband's hospital room. Very frightening & debilitating. Called former GI dr & he took me off 1 of the drugs & I slogged it out & finally got well again but at what cost? I'm 1 that get frequent flare ups. Now take 250 mg amoxicillin 3X day for 10 days which is very inexpensive & have no side effects. Nothing to compare to the horrible , torturous side effects of those other 2 drugs. I sought advice from 3 GI drs, and consulted 3 colorectal surgeons. It is hard to imagine that they still do not really know what causes these DVT flare ups. It's all best guess & try this or try that. With so many people suffering from DVT I can't find a major study being conducted to ID any specific bacteria that seems to get out of hand causing these repeated infections.”

“I have Lupus and Diverticulitis/IBS along with other health issues and then my cat bit my arm on top of Diverticulitis flare up so my doctors treated both with Flagyl and Cipro. I would comment more but this site will not let me please be careful with these medications”

“Used Flagyl in combo with Cipro after 4 days of IV antibiotics for a bad diverticulitis flare up. No major side effects provided that I used probiotics and yogurt religiously during the week long course. I would take a probiotics about 1-2 hours before dosage, then eat a yogurt, then another probiotic 1-2 hours after each dose. I was on a soft diet anyhow. Very little nausea but quite manageable with ginger and peppermint tea and some rest. Also drinking lots of water helped as well keep things moving and somewhat normal.”

“This is the 4th time I have had diverticulitis and one of the things I dread is having to take 500 mg of cipro (2x a day) and 500 mg of Flagyl (3x/day) for 10 days. The nausea and stomach ache are horrible. I am now on the 7th day and this morning I began thinking about why the problems remain so many hours after I take the drugs. I thought perhaps the drugs were not dissolving properly, so I cut the pills in half and took them in 2 pieces. I have not had nausea or stomach pain today. It did not help the fatigue and weakness however.”

“I have had Diverticulosis for years. The first attack was awful. Went to ER. So very very sick. Did the Flagyl/Cipro routine. felt worse. Over the years I have discovered many things. First of all you DO NOT WANT TO TAKE CIPRO. Google up Cipro. It is poison and even have groups of people with horror stories about Cipro. FLAGYL: All you have to do is ask your doctor to write brand medically necessary and the pills come coated with a smooth blue coating that slides down easily and do not dissolve in your mouth so no bad taste when taking taking Flagyl. If you have diverticulosis and get flares of diverticulitis do not wait. IMMEDIATELY start on flagyl A lot of the symptoms you all describe are not from the pills they are from the disease. No Cipro and start Flagyl immediately. I keep a supply always in the house.”

“I'm all to familiar with the Flagyl/Cipro combination......I've dealt with diverticulitis many times/years. I have tried several ways to get through the unpleasant task of ingesting these medications. I found that alternating one pill every 6 hours instead of taking two pills every 12 hours really helped. Also, taking milk with the Flagyl and making sure you eat 2 hours before and after to taking Cipro really makes a difference. Keep hydrated also. I do get the metallic taste and find that drinking water just makes it worse. I'm a huge water lover but not when taking these meds. I drink water that is cut with juice. I hope this helps.”

“I went to my doctor for lower abdominal pain and was told I had diverticulitis. I was prescribed Flagyl and Cipro. It started out with nausea so I called my doctor because I had terrible nausea and I was prescribed Zofran. I still have two and a half days left and its absolute torture!. I have never had side effects like this. Debilitating nausea, headaches, chills and sweats, lethargy, metallic taste, diarrhea and I am having trouble sleeping because of the nausea and my upset stomach. I kind of feel like I have the flu without a fever. I am up right now at 4 a.m. sipping ginger ale trying to get through the night. The pain in my abdomen has subsided. This medication is very harsh on the body”

“I went to the ER with abdominal pain, bloating, diarrhea and feeling sick. I was diagnosed with diverticulitis and was prescribed Flagyl, Bactrim, and Tramadol, none of which I have taken before. Gag! That's all I've been doing since taking the antibiotics, that and the hot & cold sweats, and feeling terrible. The worst is the Tramadol which after the third dose I will not take another. I felt terrible anxiety and googled that drug and found that is a side effect in some people. I'm sipping chamomile tea to try to help the gagging with little relief but I am taking in fluids. I have no appetite, food makes me gag when I look at it. It was good to read others comments that this is expected with the antibiotics. This is day 2, I have 5 more to go.”

“I went to ER with acute diverticulitis and was prescribed Metronidazole along with Cipro and pain pills. I was administered a couple pain shots and thought I could go home and take these meds and get better. Three days later I was back in the ER and let them admit me this time. The terrible headaches, horrific taste in my mouth, nausea and vomiting was about more than I could bare. I have had sleeve surgery and so my stomach is small, but this gave me such bad heartburn and indigestion, I could not imaging a medicine making a person this sick. I, also, had diarrhea with every bathroom trip and very dark urine. I couldn't even stand the taste of water or the food I ate tasted horrible along with a lack of appetite, lethargy, and light headedness. I finished my prescription of ten days, but I hope I never have to take this horrible drug again. One good thing about it is my diverticulitis pain is gone, and I pray it will never return.”

“I am a Flagyl survivor. Today I finish my 48 hours of it getting out of my system following 7 harrowing days of physical assault. Day 3 brought debilitating stomach pain, incapacitating nausea, dizziness/brain fog. The hospital had to confirm for me that the diverticulitis was not worse it was the medication’s side effects. What??? Is this 2018? I am a healthcare provider and this has given me insight into people’s distrust of the medical profession. The medicine first patented in in generic form...and never an attempt to refine the med to reduce side effects? Or produce alternatives? I have an intense full time job, got lucky I was sick over the long weekend (????) and just made it through day 6 and 7 at work with the use of partially effective Zofran (anti-nausea). Find any alternative drug or treatment. I just lost 10 days of my life first to illness then to the treatment. I believe quality of life matters. Good luck diverticulitis suffers! I’m with you in spirit.”

“I am taking flagyl and cipro together. I don't know what is worse - what I'm taking it for or the misery it is causing me.”

Anonymous July 29, 2018

“Took Cipro and Flagyl for a Diverticulitis flare up. I paid extra for the name brand of Cipro. Generic brand gave me all the nasty side effects people are sharing. I also found I ate something before taking either meds made a huge difference. I have had minimal side effects from either eating first plus I drink a bottle of water with every pill. This was the worst flare up I've experienced. Hopefully with some lifestyle changes it will be my last.”

“I took this for a diverticulitis abscess for ten days. I do not handle antibiotics well. I found with this one you definitely need to eat something with it. If I didn't my stomach would hurt. Mild diarrhea, tolerable. Some nausea. Otherwise no problems.”

“This stuff works if you can get through it. Have taken it along with Cipro many times for bouts of diverticulitis and once when hospitalized with C Diff. Now that I'm in my 70s is really hard to deal with the side effects. Calling doctor now to see if there's anything else I can take besides this. This was a milder case of the sickness. So harsh on the body.”

“WOW, cipro and flagyl drain your entire body. I have fought with diverticulitis off and on since age 37 and I am now age 45. I have gone 2 years since my last bout with diverticulitis. At first I hated the drugs and quit after 2-3 days - only for the pain to come back within a month. So I quickly learned to stay the course of the drugs, then I learned to monitor my diet better because my eating habits was the culprit. When I was 43, I had a flare up from diverticulitis, since I was used to the symptoms I drank a lot of water and tried to get by the pain, not a good idea man that diverticulitis spread through my urine tract, then to my liver...all because I didn’t want to take the medication...probably the worse episode”

“I'm on Flagl and cephalexin for diverticulitis. Today is day 4 and I feel lethargic. I sas in ER 2 days in a row for pain. Today feeling nauseous and getting diarrhea. I do not know if I can make it for ten days. (I am allergic to ciprofloxacin, penicillin,sulfa.) Soon as this is over going to immunologist to test if after 35 yrs. I can now tolerate some of the antibiotics I am allergic to because I have lung, urinary and now this is second bout of diverticulitis.”

“I have had to take this medicine numerous times, the ABSOLUTE best way to take it and not taste it is fill your mouth with Keifer and drop the pill in your mouth and then swallow. You will not taste the metallic taste!”

“I have had three episodes of Diverticulitus in the last five years. Because I had pretty rough experiences with Flagyl / Cipro combination in my previous episodes, I asked for the pharmacist to advise me, with my prior history in mind. I really wanted this time to be different. He said the most important advice is DO NOT USE ALCOHOL, which sounds like common sense; but that includes mouthwash. (you might swallow a bit) It's a slow recovery; absolutely. I live in So Cal and this was during a heat wave, but I slept day and night the first few days with a heating pad on my lower adbomen. The pharmacy confirmed Tylenol is okay pain, also. It's not a walk in the park, but I did better this time, even with other minor side effects.”
