Metronidazole (Flagyl) Side Effects

Allergies are so weird, everyone is different. I agree it's scary taking any new medication. I had no side effects from Metronidazole after a 200mg dose for three days for a tooth infection.

It is Trimethoprim that gave me a severe allergic response. Hands red and swollen, extreme nausea and exhaustion for 2 days. Slight soreness corner of mouth and slight thrush appeared two days later. Prescribed 6 but only took 2 x 200mg tablets.

I read an article today about research into DNA and allergies to drugs.
I think it is a great idea, unfortunately too late for me, with my multiple allergies. One RA drug caused a heart attack.

How awful Marydoll I hope you are OK now.

That's why I hate taking new medication. But this one according to the pharmasist I have taken once before. Probably years ago as I don't recall the name.

It’s strange isn’t it? So many people have terrible side effects with this drug, and others like myself, no side effects at all. I suppose it just goes to show how we’re all different.

I had a tooth abcess and was put on this and had severe vomiting,stomach pains and the most awful sulphuric smell. I only took 3 days worth and then my dentist changed me to another antibiotic which was fine..

Have no side effects whatsoever when taking this medicine previously. I took it for months continuously once to clear up a severe C Diff infection.

Avoiding alcohol while taking it (and for a few days afterwards) means avoiding any alcohol whatsoever - so beware of things like mouthwash too, or any foods which may contain even a small amount of alcohol.

My dentist did say to take it at mealtimes to avoid nausea - I hate to think what it would have been like otherwise....

Thank you .... I don't smoke and I haven't had any alcohol since before lockdown.
I have back pain (different to my usual) headache, brain fog & metallic taste.
I did also have lightheadedness and heartburn, but the heartburn may have been because I stopped my Omeprazole to take the antibiotics.

Nausea & stomach pain

I had to stop taking it almost immediately, so debilitating was the nausea it caused. My GP helpfully provided an alternative prescription.

Yes, it’s a definite no-no to alcohol while taking this. Not that you would of course….

My reaction was so severe, I spent an extra two days post op in hospital.
Its now on my allergy list.

It can cause stomach upsets.

I had a course of this recently because of a dental infection. I had nausea and an unpleasant taste which lasted a couple of days longer. It is important not to drink alcohol according to the instructions. I took some probiotics afterwards.
