Cefazolin (INN), also known as cefazoline or cephazolin, is a first-generation cephalosporin antibiotic.

The drug is usually administrated by either intramuscular injection (injection into a large muscle) or intravenous infusion (intravenous fluid into a vein).

Cefazolin is mainly used to treat bacterial infections of the skin. It can also be used to treat moderately severe bacterial infections involving the lung, bone, joint, stomach, blood, heart valve, and urinary tract. It is clinically effective against infections caused by staphylococci and streptococci of Gram-positive bacteria. These organisms are common on normal human skin. Resistance to cefazolin is seen in several species of bacteria.
