- Prescription medication
Omnicef is a prescription medication used to stop harmful strains of bacteria from penetrating healthy cells. Its active ingredient is cefdinir. Cefdinir is a type of antibiotic that targets bacterial infections. It’s typically used to treat pneumonia, bronchitis, and other bacterial infections (in the skin, ear, sinuses, tonsils, and throat). Omnicef is taken as an oral capsule or in liquid form.
Cefdinir works through cell wall synthesis — a process antibiotics perform in the body to prevent harmful bacteria from growing. It interferes with how bacteria build their cell walls, making it tough for them to keep their shape and survive, ultimately causing them to die off.
