Zithromax

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.

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.

Do NOT use Zithromax if:

• you are allergic to any ingredient in Zithromax, to other macrolide antibiotics (eg, erythromycin), or to ketolide antibiotics (eg, telithromycin)
• you are taking pimozide

Contact your doctor or health care provider right away if any of these apply to you.

Before using Zithromax:

Some medical conditions may interact with Zithromax. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

• if you are pregnant, planning to become pregnant, or are breast-feeding
• if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
• if you have allergies to medicines, foods, or other substances
• if you have liver or kidney problems or abnormal heart rhythms

Some MEDICINES MAY INTERACT with Zithromax. Tell your health care provider if you are taking any other medicines, especially any of the following:

• Rifampin because it may decrease Zithromax's effectiveness
• Anticoagulants (eg, warfarin), digoxin, disopyramide, pimozide, or rifampin because the risk of their side effects may be increased by Zithromax
• Theophylline because blood levels may temporarily decrease after stopping Zithromax

This may not be a complete list of all interactions that may occur. Ask your health care provider if Zithromax may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
