Cefixime is used to treat infections of the respiratory tract (such as bronchitis and pneumonia), urinary tract infections, ear infections (otitis media), and gonorrhea. It is particularly effective against certain gram-negative bacteria and is often chosen when other antibiotics are not suitable.
As a cephalosporin antibiotic, cefixime works by binding to specific penicillin-binding proteins and inhibiting the synthesis of bacterial cell walls. This weakens the bacterial cell wall, causing the bacteria to rupture and die.
Patients with penicillin allergies may have cross-reactivity and should use caution. Common side effects include diarrhea, nausea, and abdominal discomfort. It is important to complete the full course of treatment even if symptoms improve. Anticoagulant monitoring may be needed in some patients.
