What Is Principen?
Principen (ampicillin) is a prescription medication used to manage bacterial infections caused by susceptible organisms. It works by inhibiting bacterial cell wall synthesis, which prevents bacteria from growing and leads to their destruction. With the right dose and ongoing monitoring, most patients experience significant improvement within the prescribed course of treatment.

Is Online Principen Treatment Right for You?
Principen (ampicillin) may be appropriate for adults who have a confirmed or clinically suspected bacterial infection caused by ampicillin-susceptible organisms, including infections of the urinary tract, respiratory tract, skin, or gastrointestinal tract. A physician will review your symptoms and medical history to determine whether Principen is the right antibiotic for your infection.
Because ampicillin is a penicillin-class antibiotic, your prescribing physician will ask about any history of penicillin or beta-lactam allergy, prior antibiotic use, and any kidney or liver conditions that could affect how your body processes the medication.
