Shake well the bottle of Zithromax® oral liquid before each use. Measure your dose correctly with a marked measuring spoon, oral syringe, or medicine cup. The average household teaspoon may not hold the right amount of liquid.
Measure the Zmax® extended-release oral suspension with a marked measuring spoon, syringe, or cup. You or your child must take this medicine within 12 hours after it has been mixed with water. It is best to take the Zmax® extended-release oral suspension on an empty stomach or at least 1 hour before or 2 hours after a meal. If your child does not use all of the medicine in the bottle, throw it away after you give the dose.
If you or your child vomits within one hour of taking the Zmax® extended-release oral suspension, call your doctor right away to see if more medicine is needed.

If you are taking aluminum or magnesium-containing antacids, do not take them at the same time that you take Zithromax®. These medicines may keep azithromycin from working properly. However, you can take antacids with Zmax®.
