General Information on Dosing With Zithromax

Additional information to keep in mind when taking Zithromax include the following:
  • Zithromax should be taken at the same time each day to maintain an even level in your system.
  • Both tablets and immediate-release liquid suspensions can be taken with or without food. If the medication upsets your stomach, try taking it with food.
  • The extended-release suspension should be taken without food, either one hour before eating or two hours after.
  • Drink a full glass of water with each dose of Zithromax.
  • For Zithromax to work properly, you have to take it as prescribed.
  • Make sure that you complete your entire prescription, even if you start feeling better. This will ensure that the infection is completely treated.
  • Never take outdated Zithromax. Taking any outdated medication may cause serious problems because the intended effects often change after expiration.
  • If you are unsure about anything related to your Zithromax dosage, please talk with your doctor or pharmacist. Do not stop taking the drug without first discussing it with your healthcare provider.
