What Experts Say
Cefazolin belongs to the first generation cephalosporin group of antibiotics. It works by stopping bacteria from building a proper cell wall, which causes the bacteria to weaken and die. It is especially effective against gram positive bacteria such as staphylococcus and streptococcus, along with some gram negative organisms.
Because cefazolin only comes as an injection, it is given into a vein or muscle by a trained healthcare worker rather than taken at home. This route lets the drug reach a high blood concentration quickly, which is useful for serious infections and for preventing infection during surgery. Hospitals often give a single dose shortly before an operation begins.
Antibiotic misuse and resistance are a growing concern across Pakistan, so cefazolin should only be used with a valid prescription and under medical supervision. Patients should complete the full course their doctor recommends, even if symptoms improve after the first few doses. Anyone with a known allergy to penicillin or cephalosporins should tell their doctor first.
