Before taking Zithromax
You should not use Zithromax if you are allergic to azithromycin or to similar drugs such as clarithromycin, erythromycin, or telithromycin.
To make sure Zithromax is safe for you, tell your doctor if you have:
- liver disease;
- kidney disease;
- myasthenia gravis;
- a heart rhythm disorder; or
- a history of Long QT syndrome.
How to take Zithromax?
- Take Zithromax 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 with Zithromax may not be the same for every type of infection.
- Shake the oral suspension (liquid) well just before you measure a dose. Measure the liquid with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
- Use Zithromax 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.
- Store at room temperature away from moisture and heat. Throw away any unused liquid medicine after 10 days.
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.
What should I avoid while taking Zithromax?
Do not take antacids that contain aluminum or magnesium within 2 hours before or after you take Zithromax. This includes Gaviscon, Maalox, Milk of Magnesia and others. These antacids can make azithromycin less effective when taken at the same time.
Antibiotic medicines can cause diarrhoea, which may be a sign of a new infection. If you have diarrhoea that is watery or bloody, stop taking Zithromax and call your doctor. Do not use anti-diarrhoea medicine unless your doctor tells you to.
Avoid exposure to sunlight or tanning beds. Zithromax can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
