Enfuvirtide - injection
Enfuvirtide - injection
This drug is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life.
Enfuvirtide is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, do all of the following: (1) continue to take all HIV medications exactly as prescribed by your doctor, (2) always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity, and (3) do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.
This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
This product may also be used to lessen the risk of HIV infection after contact with the virus (for example, due to a needle stick). Ask your doctor for more details.
Read the Patient Information Leaflet if available from your pharmacist before you start using enfuvirtide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
