Ampicillin is a highly effective antibiotic, and is one of the top prescribed medications by doctors!
Ampicillin may also be marketed as: Principen, Totacillin, Omnipen-N, Polycillin, Principen.
Ampicillin is an antibiotic in the penicillin group of drugs. It fights bacteria in your body. Ampicillin is used to treat many different types of infections caused by bacteria such as ear infections, bladder infections, pneumonia, gonorrhea, and E. coli or salmonella infections.
Use Ampicillin as directed by your doctor.
Take Ampicillin by mouth at least 30 minutes before or 2 hours after eating, with a full glass of water (8 oz/240ml). Take Ampicillin on a regular schedule to get the most benefit from it, and take it for as long as your doctor instructed you. Do NOT take less or more of your instructed dosage. Taking Ampicillin at the same time each day will help you remember to take it.
To clear up your infection completely, use Ampicillin for the full course of treatment. Keep using it even if you feel better in a few days.
