Frequently Asked Questions

What is Zithromax 250mg and what is it used for?

How does Zithromax 250mg work in the body?

Azithromycin works by stopping bacteria from growing and multiplying. Once the bacteria stop spreading, your body can fight the infection more easily.

Take it exactly as your doctor prescribes. It can usually be taken with or without food, but if it upsets your stomach, take it after a meal. Try to take it at the same time every day, and never skip doses. Even if you start feeling better, finish the full course — stopping early may let the infection return or cause resistance.
