Benzathine benzylpenicillin (rINN) is a form of penicillin also known as benzathine penicillin.

Pain and inflammation at the injection site is also common for parenterally administered benzathine benzylpenicillin, benzylpenicillin, and, to a lesser extent, procaine benzylpenicillin.

The treatment of choice is a single dose of benzathine benzylpenicillin given by intramuscular injection, or a five-day to one-week course of either oral penicillin or intramuscular procaine benzylpenicillin.
