Zithromax

Zithromax is an antibiotic that fights bacteria.

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

To reduce the development of drug-resistant bacteria Zithromax should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria.

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 may not be the same for every type of infection.

Zithromax can be taken with or without food.

Shake the oral suspension (liquid) well before measuring 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. Zithromax will not treat a viral infection such as the flu or a common cold.

Store at room temperature away from moisture and heat. Throw away any unused liquid medicine after 10 days.

You should not use Zithromax if you have ever had jaundice or liver problems caused by taking azithromycin.

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

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

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

• liver disease;
• kidney disease;
• myasthenia gravis;
• heart problems, including heart failure, a slow heartbeat, or a heart rhythm disorder;
• low levels of potassium in your blood; or
• long QT syndrome (in you or a family member). Zithromax is not recommended for use in people who cannot tolerate oral medicines because they are very ill or have certain other risk factors, including cystic fibrosis, hospital-acquired infections, or a bacterial infection in the blood.

It is not known if Zithromax will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

Zithromax can pass into breast milk. Tell your doctor if you are breastfeeding a baby. Contact your doctor immediately if your nursing baby vomits, has diarrhea, develops a rash, or becomes irritable.

Get emergency medical help if you have signs of an allergic reaction to Zithromax: (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).

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 Zithromax.

Call your doctor at once if you have:

• severe stomach pain, diarrhea that is watery or bloody;
• fast or pounding heartbeats, fluttering in your chest, chest discomfort, shortness of breath, sudden dizziness (like you might pass out), or heart stopping (cardiac arrest); or
• liver problems - nausea, upper stomach pain, itching, tired feeling, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).

Call your doctor right away if a baby taking Zithromax becomes irritable or vomits while eating or nursing.

Older adults may be more likely to have side effects on heart rhythm, including a life-threatening fast heart rate.

Common Zithromax side effects may include:

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

This is not a complete list of side effects, and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

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.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Do not take antacids that contain aluminum or magnesium within 2 hours before or after you take Zithromax. This includes Acid Gone, Aldroxicon, Alternagel, Di-Gel, Gaviscon, Gelusil, Genaton, Maalox, Maldroxal, Milk of Magnesia, Mintox, Mylagen, Mylanta, Pepcid Complete, Rolaids, Rulox, and others. These antacids can make Zithromax less effective when taken at the same time.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. Tell your doctor right away if you have watery diarrhea, diarrhea that does not go away, or bloody stools. You may also experience stomach cramps and a fever. This could happen as late as 2 or more months after you have finished taking Zithromax. Do not use anti-diarrhea 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.

Tell your doctor about all your current medicines and any you start or stop using, especially:

• nelfinavir;
• a blood thinner - warfarin, Coumadin, Jantoven.
• digoxin;
• colchicine.
• phenytoin.
