Penicillin antibiotics are often used to treat a wide range of bacterial infections, including respiratory tract infections (such as pneumonia, bronchitis, and sinusitis), skin and soft tissue infections, urinary tract infections, and certain sexually transmitted diseases. They are particularly effective against infections caused by Gram-positive bacteria, but may also be used in combination with other antibiotics to treat more complex infections.
