Important info

You should not use Zithromax if you have ever had jaundice or liver problems caused by taking azithromycin. You should not use Zithromax if you are allergic to it or to similar drugs such as erythromycin (E.E.S., EryPed, Ery-Tab, Erythrocin, Pediazole), clarithromycin (Biaxin), telithromycin (Ketek), or troleandomycin (Tao).

There are many other medicines that can interact with Zithromax. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor. Keep a list of all your medicines and show it to any healthcare provider who treats you.

Take this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Zithromax will not treat a viral infection such as the common cold or flu. Avoid taking an antacid within 2 hours before or after you take Zithromax. Some antacids can make it harder for your body to absorb Zithromax.
