Selzentry

Generic name: Maraviroc
Drug class: Chemokine receptor antagonist

Usage of Selzentry

Selzentry is an antiviral medicine that prevents certain viral cells from multiplying in your body.

Selzentry prevents human immunodeficiency virus (HIV) from multiplying in your body.

Selzentry is used with other medications to treat CCR5-tropic HIV type 1, a virus that can cause acquired immunodeficiency syndrome (AIDS). Selzentry is not a cure for HIV or AIDS.

Selzentry is for use in adults and children who weigh at least 4.4 pounds (2 kilograms).

Selzentry side effects

Get emergency medical help if you have signs of an allergic reaction to Selzentry (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).

Stop taking Selzentry and seek medical treatment at once if you have a serious drug reaction that can affect many parts of your body (especially your liver). Symptoms may include: itching or rash, fever, swollen glands, muscle or joint aches, severe weakness, unusual bruising, upper stomach pain, vomiting, dark urine, or jaundice (yellowing of the skin or eyes).

Call your doctor at once if you have a side effect such as:

a light-headed feeling, like you might pass out; or

chest pressure, tight feeling in your neck or jaw, sweating, pain spreading to your arm or shoulder.

Selzentry affects your immune system, which may cause certain side effects (even weeks or months after you've taken this medicine). Tell your doctor if you have:

signs of a new infection - fever, night sweats, swollen glands, cold sores, cough, wheezing, diarrhea, weight loss;

trouble speaking or swallowing, problems with balance or eye movement, weakness or prickly feeling; or

swelling in your neck or throat (enlarged thyroid), menstrual changes, impotence.

Common Selzentry side effects may include:

fever, cold symptoms, cough;

indigestion, gas, bloating, nausea, vomiting, diarrhea, constipation;

rash;

dizziness; or

(in newborns) abnormal blood tests.

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.

Before taking Selzentry

If you have severe or end-stage kidney disease, you may not be able to take Selzentry if you use certain medications, including some antibiotics or antifungal medications, some heart or blood pressure medicines, St. John's wort, and certain drugs to treat hepatitis or tuberculosis. Tell your doctor about all other medications you use.

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

kidney disease (or if you are on dialysis);

liver disease, especially hepatitis B or C;

heart disease; or

low blood pressure.

Maraviroc affects your immune system and may possibly increase your risk of developing infections or cancer. Ask your doctor about this risk.

Tell your doctor if you are pregnant, and use your medications properly to control your infection. HIV can be passed to your baby if the virus is not controlled during pregnancy. Your name may be listed on a registry to track any effects of antiviral medicine on the baby.

Women with HIV or AIDS should not breastfeed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.

Selzentry is not approved for a premature baby, or a child who weighs less than 4.4 pounds (2 kilograms).
