Definition & Meaning of "penicillin"

What is "penicillin"?

Penicillin is an antibiotic medication used to treat bacterial infections. It belongs to a type of antibiotics called beta-lactams, which work by stopping the bacteria's ability to build their cell walls, leading to their destruction. Penicillin is effective against a wide range of bacterial infections, including strep throat, skin infections, ear infections, and certain sexually transmitted diseases. It was the first antibiotic discovered and has since saved countless lives by fighting bacterial infections effectively. However, some individuals may be allergic to penicillin, so it is important to inform healthcare providers before taking it.
