Azithromycin is an antibiotic used to treat mild to moderate infections caused by certain bacteria, including respiratory infections, skin infections, and some sexually transmitted infections. It works by stopping bacteria from growing and multiplying, helping your body to fight off the infection. The medication can be taken as a tablet or liquid, with a common starting dose of 500 mg on the first day, followed by 250 mg daily for the next four days, and it should not exceed 1500 mg total. It's important to know that azithromycin should not be used if you have had a severe allergic reaction to it or similar antibiotics in the past. Additionally, be cautious if you are taking medications that affect heart rhythm, as azithromycin can increase the risk of serious heart problems in those cases.
