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

[edit] Indications
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.
[edit] Adverse effects
Adverse drug reactions from cefazolin are not common. Possible side effects include diarrhea, stomach pain or upset stomach, vomiting, and rash.
Like that of several other cephalosporins, the chemical structure of cefazolin contains an N-methylthiotetrazole (NMTT or 1-MTT) side-chain. As the antibiotic is broken down in the body, it releases free NMTT, which can cause hypoprothrombinemia (likely due to inhibition of the enzyme vitamin K epoxide reductase) and a reaction with ethanol similar to that produced by disulfiram (Antabuse), due to inhibition of aldehyde dehydrogenase.[1]
[edit] Brands
Cefazolin is marketed under the following brand names: Cefacidal, Cefamezin, Cefrina, Elzogram, Faxilen, Gramaxin, Kefazol, Kefol, Kefzolan, Kezolin, Novaporin, Reflin, Zinol and Zolicef.
