Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
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.
How To Use
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.
Inject this medication under the skin (subcutaneously) usually twice daily into the upper arm, thigh, or abdomen. Do not inject into the buttock or near the elbow, knee or groin. Rotate injection sites with each shot. Do not inject in or near bumps from past injections. Also, do not inject into moles, scars, bruises, tattoos, burn areas, or your belly button.

Pain, redness, itching, bruising, hardened skin, or bumps at the injection site may occur. These types of reactions are common and may last up to 7 days. Runny nose may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including:
- unexplained weight loss
- severe tiredness
- muscle aches/weakness that doesn't go away
- headaches that are severe or don't go away
- joint pain
- numbness/tingling of the hands/feet/arms/legs
- vision changes
- signs of infection (such as fever, chills, swollen lymph nodes, trouble breathing, cough, non-healing skin sores)
- signs of an overactive thyroid (such as irritability, nervousness, heat intolerance, fast/pounding/irregular heartbeat, bulging eyes, unusual growth in the neck/thyroid known as a goiter)
- signs of a certain nerve problem known as Guillain-Barre syndrome (such as trouble breathing/swallowing/moving your eyes, drooping face, paralysis, trouble speaking)
- signs of liver disease (such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine)
Tell your doctor right away if you have any serious side effects, including:
- numbness/tingling/shooting nerve pain near injection site
- signs of injection site infection (such as oozing, warmth, persistent pain and redness)
- abdominal pain
