What is azithromycin?

Azithromycin is an antibiotic that fights bacteria.

Azithromycin is used to treat many different types of infections caused by bacteria, such as respiratory infections, skin infections, ear infections, eye infections, and sexually transmitted diseases.

Azithromycin may also be used for purposes not listed in this medication guide.

Warnings

You should not use azithromycin if you have ever had jaundice or liver problems when you have previously taken this medicine.

Before taking this medicine

You should not use azithromycin if you are allergic to it, or if:

  • you have ever had jaundice or liver problems caused by taking azithromycin; or
  • you are allergic to similar drugs such as clarithromycin, erythromycin, or telithromycin.

To make sure azithromycin is safe for you, tell your doctor if you have ever had:

  • liver disease;
  • kidney disease;
  • myasthenia gravis;
  • a heart rhythm disorder;
  • low levels of potassium in your blood; or
  • long QT syndrome (in you or a family member).

This medicine is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether azithromycin passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How should I take azithromycin?

Take azithromycin exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. The dose and length of treatment may not be the same for every type of infection.

You may take most forms of azithromycin with or without food.

Take Zmax extended release liquid (oral suspension) on an empty stomach, at least 1 hour before or 2 hours after a meal.

To use the oral suspension single dose packet: Open the packet and pour the medicine into 2 ounces of water. Stir this mixture and drink all of it right away. Do not save for later use. To make sure you get the entire dose, add 2 more ounces of water to the same glass, swirl gently and drink right away.

Throw away any mixed Zmax oral suspension (extended release formulation) that has not been used within 12 hours. Throw away any immediate-release suspension that has not been used within 10 days.

Shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Use 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. Azithromycin will not treat a viral infection such as the flu or a common cold.

Store at room temperature away from moisture and heat.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

These antacids can make azithromycin less effective when taken at the same time.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.

Avoid exposure to sunlight or tanning beds. Azithromycin can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.

Seek medical treatment if you have a serious drug reaction that can affect many parts of your body. Symptoms may include: skin rash, fever, swollen glands, flu-like symptoms, muscle aches, severe weakness, unusual bruising, or yellowing of your skin or eyes. This reaction may occur several weeks after you began using azithromycin.

Call your doctor at once if you have:

  • diarrhea;
  • nausea, vomiting, stomach pain; or
