I think I got every side effect you could get with this nasty stuff. It manifested itself slowly so I wasn't sure if I was losing my mind or what! I've had metal mouth, nausea, bruising, furry tongue, and most of all just didn't feel right in the head. Couldn't communicate, panic attacks, crying for no real good reason. This stuff is awful!

I just finished a 10 day (4xday) prescription of Flagyl (250 mg) prescribed by my Gastro doctor for treatment of (SIBO) Severe Intestinal Bacterial Overgrowth. Two days after finishing Flagyl I broke out in hives all over my body and my upper eyelids were very swollen. Now my dermatologist has me on Zyrtec and Prednisone. Has anyone broken out with hives and had swollen eyes from taking Flagyl?

I was in hospital for 16 days - no food no water - had flagyl and levaquin in IV form - i had pancreatitis - my gall bladder is fine - they did every test imaginable to me and gave no reason for the sudden flare-up of pancreatitis - i do not drink at all - my hubby is 27 years into his recovery = the meds made me feel really weird - like my tongue was dissolving like alka seltzer - my tongue was coated totally green- i kept vomiting and feeling so exhausted but i could not sleep - how can they fda approve drugs like this?

I was prescribed this drug for C-Diff.
This is my 2nd time taking this drug for the C-Diff.
It absolutely makes me so miserable,
physically and mentally.
I feel bad all over.
It's hard to describe, you feel like
you're going to die or something.
I have an extremely bad headache.
My shoulders and hands hurt.
I ache and feel weak.

I took the metronidazole for about four days.
I went to bed one night and woke up with the worst shoulder pain possible, it feels like I just had surgery on it. it's been this way for about 3 days, so I am stopping the medication.

After 1 day of taking this medication, my body instantly didn't agree with it. I experienced dizziness, nausea, dry mouth, no appetite and the worst diarrhea that i ever experienced. I also kept vomiting and recieved a yeast infection in the process. Finally after 3 days I stopped it under my own discretion. My doctor couldn't believe it was doing of this in 3 days. Every medication isn't for everyone

Flagyl has been used with Septra to treat a bacterial infection that resulted from an infected cyst in my rectal area. Below I've listed some of the horrific side effects I think are from this medication. I'm going to ask the surgeon tomorrow.

This is not a new side effect, but I wanted to let other people who are taking Flagyl to hear this and hope it will help them while they are taking this awful medication. The pill form is the worst medication I have ever had to swallow. I found that if I coat the pill in butter, I can swallow the pill without gagging and I have no aftertaste. I also eat a couple of crackers before I take it, to stop the stomach upset.

I had the usual side effects: nausea, diarrhea, bad taste, etc. I wasn't able to finish the 10 day course (only 7 1/2). My biggest complaint is the bad taste and the furry yellow tongue. My doctor gave me an anti-fungal but it hasn't gone away. It has been 2 weeks since my last dose and my tongue is still yellow and furry! I am disgusted and embarrassed.

This stuff is aweful. I took 6 pills total over 3 days, and wow, headaches, burning left foot (comes and goes, mostly after up walking aroung then sitting down) Pressure in the back of my head is aweful. I haven't taken this drug for 4 days, but still have these stupid side effects. Anyone have any reassuring comments for me? Has anyone had this problem and did it go away after a while?

nausea, nausea, and more nausea. hasn't gone away yet and it's been over a year. I have asked numerous pharmacists and they say that it should not have lasted this long but ......? The nausea started the 7th and last day that I took it and I was somewhat fine before. Had cdiff.

My Dad's doctor put him on this. Before he was put on it he was up walking around and saying a few words, laughing with us. Now he is in a wheelchair and not eating. My dad has Alztimers (?) so he don't talk much anyways but we have notice that he don't like to eat anymore not even ice cream that he use to love daily. His urine is brownish with a little red in it. My dad can't speak for himself to tell us what hurts or what's wrong with him but my Mom and I can that something is wrong.
This medication is awful I wouldn't say anything nice about it.

I thought this stuff was going to kill me! Sure I could live with the bad taste and the feeling like I was going to hurl, I could even handle the thrush. But then it started to effect my mind. It made me feel so ill. I had confusion, I would get disoriented. Then it got to the point my arms head and neck would have uncontrollable jerky movements. Then it messed with my speech. It was hard to get the words out. While trying to talk I would just start to cry, all the while my arms are flaring. Some thought I must have had a stroke. I looked like I had Parkinson Disease. I took this for about a total of 5 days. The first 2 days were okay, just felt pressure in my head behind my eyes and in my ears. By day three I felt like someone slipped me something bad. That was when the jerks and speech problems started. Once the medication was stopped, it was 72 hours later that the jerking movements stopped and I could speak normally. I was prescribed this for c-diff. The c-diff was a walk in the park compared to what this drug did to me. The doctor says those side effects can happen but it was VERY rare. I guess I was the rare one. So I say it is a VERY bad drug. But it is hard to say if I may have an underline condition that is not known and this drug just brought it to the surface. Either way I would avoid this like drug, that is just my opinion. I now know what hell must be like.

I won't take metronidazole again. I have such pain in my both shoulders and aches and pains all over. Have been so tired, just want to sleep. The doctor said it isn't from the medicine, but Arthritis. I really think it is the medicine.

I was perscribed several doses of flagyl for Cdif, and after about 4 months I developed complete numbness of my toes. I immediately stopped medication and feeling returned to my toes in about 5 to 6 months. Now it is 2 years later and I am having painful numbness in my arms and toes when I sleep. Though I am no longer taking the drug I believe the two are connected.

Have had serious side effects: pain in tingling in all extremities, severe muscle and tendon pain, join popping and pain, nausea, headaches, mental confusion, difficulty talking, walking or lifting, dizziness and lightheadedness, and everything I eat and drink tastes terrible like I'm eating metal. My doctor says he has never had a patient react with every possible severe reaction. Well, now he has...
