Uses

PENICILLIN V (Pen-Vee K, V-Cillin K) is a penicillin antibiotic. Penicillin V kills certain bacteria that cause infection, or stops their growth. It treats many kinds of infections including those of the skin, brain, heart, respiratory tract, sinuses, and ears. Generic penicillin V tablets are available.

How to take
