What Experts Say

Cefixime belongs to the third generation of oral cephalosporin antibiotics. It works by stopping bacteria from building their protective cell walls, which weakens and eventually kills the bacteria. Doctors often favor it because a single tablet keeps working in the body for several hours, unlike some older antibiotics that need more frequent dosing.

Pakistan faces a rising problem of antibiotic resistance, largely linked to self-medication and incomplete antibiotic courses. Health experts stress that Cefixime should only be taken after a doctor confirms a bacterial infection, since it has no effect on viral illnesses like flu or the common cold. Unnecessary use speeds up resistance for the whole community.

Doctors also caution that stopping the tablet early, even once symptoms improve, allows surviving bacteria to multiply again. A full prescribed course, usually five to ten days, gives the best chance of complete recovery. Anyone with kidney disease or a past penicillin allergy should discuss the cross-reaction risk with a doctor before starting treatment.

Drug Interactions
