Phenoxymethylpenicillin, also known as penicillin V, is an antibiotic useful for the treatment of a number of bacterial infections.

Specific indications for phenoxymethylpenicillin include:
Penicillin V is sometimes used in the treatment of infections.
It is less active than benzylpenicillin (penicillin G) against Gram-negative bacteria. Phenoxymethylpenicillin has a range of antimicrobial activity against Gram-positive bacteria that is similar to that of benzylpenicillin and a similar mode of action, but it is substantially less active than benzylpenicillin against Gram-negative bacteria.
