What Experts Say

Doctors across Pakistan prescribe the 250mg strength of cefazolin for infections that do not need the higher dose. It suits children, older adults and patients with mild to moderate infections. This flexibility makes it a common choice in general wards. It is often used alongside other treatments for moderate infections.

Like other first-generation cephalosporins, cefazolin stops bacteria from building a working cell wall. The bacteria weaken and die, which clears the infection over a few days of treatment. It is given only by injection since the stomach breaks it down if swallowed.

Doctors adjust the dose carefully in patients with reduced kidney function, since the drug leaves the body through the kidneys. A penicillin allergy history is always checked first, because cross-reactions with cephalosporins can occur. The full course is finished even once symptoms settle. This prevents the infection from returning.
