Erythromycin is a macrolide antibiotic used to treat a range of bacterial infections.
It is commonly used for:
• Respiratory tract infections: Treats bacterial bronchitis, pneumonia, and whooping cough.
• Skin infections: Clears bacterial skin infections, including acne when applied topically.
• Ear, nose, and throat infections: Treats bacterial infections of the throat and sinuses.
• Sexually transmitted infections: Used to treat certain bacterial STIs.
• Gastrointestinal motility disorders: Sometimes used to help stimulate stomach and bowel movement, under medical supervision.

Erythromycin works by stopping bacteria from producing the proteins they need to grow and multiply.
It binds to a part of the bacterial ribosome, the structure responsible for building proteins, and blocks this process.
Without the ability to produce new proteins, bacteria cannot grow or repair themselves, allowing the immune system to clear the infection. Applied to the skin, this same antibacterial action helps reduce acne-causing bacteria.
