How to use Selzentry:

Important safety information:

• Selzentry may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Selzentry with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.


• Selzentry may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. Your risk may be greater if you have severe kidney problems. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.


• Do NOT take more than the recommended dose or use more often than prescribed without checking with your doctor.


• Certain other medicines for HIV (eg, HIV protease inhibitors, delavirdine, efavirenz) may increase the side effects of Selzentry or decrease its effectiveness. Talk with your doctor about all of your HIV medicines. Do not start, stop, or change the dose of any HIV medicine unless your doctor tells you to.


• Selzentry may improve immune system function. This may reveal hidden infections in some patients. Tell your doctor right away if you notice symptoms of infection (eg, fever, sore throat, weakness, cough, shortness of breath) after you start Selzentry.


• Selzentry may increase the risk of developing an infection. Avoid contact with people who have colds or infections. Tell your doctor if you notice signs of infection like fever, sore throat, rash, or chills. Discuss any questions or concerns with your doctor.


• It is possible that Selzentry may increase the risk of developing cancer. No increase in cancer cases has been seen in patients who take Selzentry. Discuss any questions or concerns with your doctor.


• Selzentry is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.


• When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking Selzentry, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.


• Selzentry does not stop the spread of HIV to others through blood or sexual contact. Use barrier methods of birth control (eg, condoms) if you have HIV infection. Do not share needles, injection supplies, or items like toothbrushes or razors.


• Lab tests, including liver function, may be performed while you use Selzentry. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.


• Use Selzentry with caution in the ELDERLY; they may be more sensitive to its effects.


• Selzentry should not be used in CHILDREN younger than 16 years old; safety and effectiveness in these children have not been confirmed.


• PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Selzentry while you are pregnant. It is not known if Selzentry is found in breast milk. Mothers infected with HIV should not breast-feed. There is a risk of passing the HIV infection or Selzentry to the baby.
