azithromycin over the counter is an antibiotic used to treat a variety of bacterial infections. It is commonly prescribed for respiratory infections like bronchitis and pneumonia, as well as ear infections, skin infections, and sexually transmitted diseases such as chlamydia and gonorrhea. Azithromycin works by inhibiting bacterial protein synthesis, which helps to stop the growth and spread of bacteria. It is often favored for its long half-life, which allows for shorter treatment courses compared to other antibiotics. This makes it a convenient option for treating infections while minimizing the risk of antibiotic resistance.
