Can the amoxicillin effect the Depo Provera shot?
No, amoxicillin will not decrease the effectiveness of the Depo-Provera to prevent an unintended pregnancy. Since the Depo-Provera shot bypasses the absorption phase in the gastrointestinal tract required by oral contraceptives, antibiotics such as amoxicillin will not interfere with the effectiveness of the Depo shot.
