Belonging to the macrolide class of antibiotics, erythromycin works by inhibiting bacterial protein synthesis, effectively stopping the growth of bacteria. It is commonly prescribed for respiratory tract infections, skin infections, ear infections, and certain sexually transmitted diseases. Available in various strengths, erythromycin tablets are taken orally, typically on an empty stomach, as directed by a healthcare provider.
