A member asked:

How long for metronidazole and clarithromycin to get out of your system?

Dr. Michael Ein answered

Specializes in Infectious Disease

40 and 15-20 hours: The half life of Metronidazole is 8 hours. The half life of Clarithromycin is 3-4 hours. Half life is the time for the body to eliminate and excrete 1/2 of the drug. It is felt that a drug is completely eliminated after 5 half lives. So 40 hours for Metronidazole and 15-20 hours for clarithromycin.
