Zithromax is used for treating mild to moderate infections caused by certain bacteria. It may also be used alone or with other medicines to treat or prevent certain infections in persons with advanced HIV infection. It may also be used for other conditions as determined by your doctor.
How to use
Use Zithromax as directed by your doctor. Check the label on the medicine for exact dosing instructions.
Take Zithromax by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
Do not take an antacid that has aluminum or magnesium in it within 1 hour before or 2 hours after you take Zithromax.
Zithromax works best if it is taken at the same time each day.
To clear up your infection completely, use Zithromax for the full course of treatment. Keep using it even if you feel better in a few days.
Drug Class and Mechanism
Zithromax is a macrolide antibiotic. It slows the growth of, or sometimes kills, sensitive bacteria by reducing the production of important proteins needed by the bacteria to survive.
Missed Dose
If you miss a dose of Zithromax, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Storage
Zithromax tablets should be stored between 15 to 30 degrees C (59 to 86 degrees F). Store constituted suspension between 5 to 30 degrees C (41 to 86 degrees F) and discard when full dosing is completed or within 10 days. Shake well before each use. Oversized bottle provides shake space. Keep tightly closed.
