Why is this medication prescribed?
Fuzeon (enfuvirtide) is prescribed for the treatment of HIV-1 infection. It is typically used in combination with other antiretroviral medications for patients who have developed resistance to other HIV drugs or who have advanced HIV infection.
Fuzeon belongs to a class of drugs called fusion inhibitors, which work by blocking HIV from entering human immune cells. By preventing HIV from entering cells, Fuzeon helps to slow down the progression of HIV infection and reduce viral replication.
Fuzeon is often recommended for individuals who have limited treatment options due to resistance to other HIV medications. It is used as part of a comprehensive HIV treatment regimen to suppress viral replication, reduce viral load, and improve immune function.
Overall, Fuzeon plays a crucial role in the management of HIV infection, particularly for individuals who have limited treatment options or who require alternative medications due to drug resistance.
How should this medicine be used?
Fuzeon (enfuvirtide) is typically used in the treatment of HIV-1 infection. Here are the general guidelines for using Fuzeon:
- Administration: Fuzeon is administered via subcutaneous injection, which means it is injected under the skin. It should not be injected intravenously or intramuscularly.
- Injection sites: The injections are typically given into the fatty tissue of the upper arm, thigh, or abdomen. Rotate injection sites to prevent injection site reactions and to ensure proper absorption of the medication.
- Dosage: The recommended dosage of Fuzeon is usually 90 mg (1 mL) administered twice daily. Your healthcare provider will determine the appropriate dosage for you based on factors such as your viral load, CD4 count, and previous HIV treatment history.
- Injection technique: Before administering Fuzeon injections, ensure that you have been properly trained by a healthcare professional on the correct injection technique. Use a new needle and syringe for each injection to prevent contamination and infection.
- Storage: Fuzeon should be stored in the refrigerator at a temperature between 2°C to 8°C (36°F to 46°F). Do not freeze the medication. If refrigeration is not available, Fuzeon can be kept at room temperature (up to 25°C or 77°F) for up to 24 hours. Do not expose the medication to excessive heat or direct sunlight.
- Preparation: Before administering the injection, allow Fuzeon to come to room temperature if it has been refrigerated. Gently swirl the vial to ensure that the medication is thoroughly mixed and appears clear and colorless. Do not shake the vial vigorously.
- Injection process: Clean the injection site with an alcohol swab and allow it to dry. Pinch the skin and insert the needle at a 45 to 90-degree angle, depending on the thickness of the skin and the length of the needle. Inject the medication slowly and steadily. After injecting, remove the needle and apply gentle pressure to the injection site with a sterile cotton ball or gauze.
- Disposal: Dispose of needles, syringes, and unused medication properly in a puncture-resistant container as instructed by your healthcare provider or local guidelines.
Always follow your healthcare provider’s instructions and consult them if you have any questions or concerns about using Fuzeon or any other medication.

- Immune reconstitution syndrome: In some patients with advanced HIV infection and severe immune deficiency, signs and symptoms of inflammation from previous infections may occur soon after starting antiretroviral therapy, including Fuzeon. Notify your healthcare provider if you experience new or worsening symptoms after starting treatment with Fuzeon.
- Liver and kidney function: Regular monitoring of liver and kidney function may be necessary while taking Fuzeon, especially in patients with pre-existing liver or kidney conditions.
