What is Fuzeon?Fuzeon is a medicine used to treat HIV (human immunodeficiency virus) infection (AIDS) in combination with other anti-HIV medications. Fuzeon is a type of HIV medicine called an HIV fusion inhibitor. It works by lowering the amount of HIV in your blood and increasing the number of certain immune cells to help fight infection. Fuzeon is administered subcutaneously (just below the skin).
What is the most important information I should know about Fuzeon?You have to take Fuzeon with other HIV medicines, as prescribed by your doctor.
Always stay on continuous HIV therapy to control your HIV infection and decrease HIV-related illnesses. Though Fuzeon can slow the progress of HIV, it is not a cure. You may continue to develop infections and other complications associated with HIV.
Fuzeon does not reduce your risk of passing HIV/AIDS to others through sexual contact, sharing needles, or being exposed to your blood. Always practice safe sex to reduce the risk of transmitting HIV to others. Use latex or polyurethane condoms to lower the chance of sexual contact with any body fluids (such as semen, vaginal secretions, or blood).
Fuzeon can cause pain, discomfort, hardened skin, redness, swelling, bumps, itching, or bruising at the injection site. Tell your doctor immediately if you notice signs of an infection at the injection site (such as oozing, increasing heat, swelling, redness, or pain).
Inject Fuzeon into your upper arm, abdomen, or thigh. Do not inject this medication near areas where large nerves are close to the skin (such as your elbow, knee, or groin) to prevent the occurrence of prolonged shooting nerve pain and tingling.
Fuzeon can cause lung infections. Your risk can increase with the severity of your HIV infection, if you are an intravenous drug abuser or a smoker, or if you have a history of lung disease. Tell your doctor immediately if you have a cough with fever, rapid breathing, or shortness of breath.
Fuzeon can cause serious allergic reactions. Tell your doctor immediately if you develop a rash, fever, nausea and vomiting, chills, rigors, low blood pressure, trouble breathing, blood in your urine, or swelling of your feet.
Who should not take Fuzeon?Do not use Fuzeon if you are allergic to it or any of its ingredients.
What should I tell my doctor before I take the first dose of Fuzeon?Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Fuzeon. Also, talk to your doctor about your complete medical history, especially if you have a blood clotting disorder, have a history of lung disease, are a drug abuser or smoker, are pregnant, plan to become pregnant, or are breastfeeding.
What is the usual dosage?The information below is based on the dosage guidelines your doctor uses. Depending on your condition and medical history, your doctor may prescribe a different regimen. Do not change the dosage or stop taking your medication without your doctor's approval.

When your Fuzeon supply starts to run low, get more from your doctor or pharmacy. It is important that you do not run out of Fuzeon. If you stop the medicine for even a short time, the amount of HIV in your body can increase or it can become resistant to the effects of Fuzeon.
