A member asked:

After 10 days of taking, how long will it take flagyl to get out of my system ?

A doctor has provided 1 answer

Metronidazole: Excretion via urine of 60 to 80% of the dose with fecal excretion of 6% to 15% with unchanged Metronidazole accounting for approximately 20% of the total. Both the parent compound and the metabolites have a half-life of about 8 hours and it should all be gone in 4 to 5 half-lives. Don't drink alcohol until then.
