- An extra patient leaflet is available with enfuvirtide. Talk to your pharmacist if you have questions about this information.
- Food does not affect enfuvirtide. You may use enfuvirtide whether you have eaten or not. You must keep taking your other medicines the way you did before you started taking enfuvirtide.
- Enfuvirtide is usually given as an injection at your doctor's office, hospital, or clinic. If you will be using enfuvirtide at home, a health care provider will teach you how to use it. Be sure you understand how to use enfuvirtide. Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.
- Do not use enfuvirtide if it contains particles, is cloudy or discolored, or if the vial is cracked or damaged. If the solution is foamy or jelled, allow more time for it to dissolve.
- Enfuvirtide is injected under the skin into the upper arm, thigh, or stomach. Rotate injection sites with each shot. Do not inject near the elbow, knee, groin area, or the lower or inner buttocks. Do not inject in or near injection site reactions from past injections or directly over a blood vessel. Also, do not inject into abnormal skin, such as moles, scars, bruises, tattoos, burn sites, or your belly button.
- When drawing a dose into a syringe, be sure to follow the procedure demonstrated to you to prevent contamination of the vial, syringe, or medicine. Never touch the rubber stopper of the vial or the needle of the syringe with your fingers.
- Do not mix your other medicines in the same syringe with enfuvirtide.
- Use enfuvirtide within 24 hours after mixing it. Throw away any unused medicine left in the vial after your dose. If you do not use enfuvirtide within 24 hours after mixing it, throw it away.
- Keep this product, as well as syringes and needles, out of the reach of children and away from pets. Do not reuse needles, syringes, or other materials. Ask your health care provider how to dispose of these materials after use. Follow all local rules for disposal.
- You may use enfuvirtide with a needle-free injection device (eg, Biojector 2000). Avoid injecting into areas close to joints or large nerves. Certain nerve problems (eg, pain, numbness or tingling) may occur if the medicine is injected near these areas. Bruising or bleeding under the skin may also occur with the use of this device. The risk may be greater if you take anticoagulants (eg, warfarin) or have bleeding problems (eg, hemophilia). Check with your health care provider if you have questions about using this type of injection device.
- If you miss a dose of enfuvirtide, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once. It is important not to miss doses of enfuvirtide.

Important safety information:
- Enfuvirtide may cause dizziness. These effects may be worse if you take it with alcohol or certain medications. Use enfuvirtide with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Enfuvirtide is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.
- Enfuvirtide 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 enfuvirtide.
- When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking enfuvirtide, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.
- Do not change your dose or stop taking this or any other HIV medicine without checking with your doctor. Contact your doctor immediately if you stop taking this or any other HIV medicine.
- Enfuvirtide does not stop the spread of HIV to others through blood or sexual contact. Do not have any kind of sex without protection (eg, latex or polyurethane condoms) if you have HIV infection. Do not share needles, injection supplies, or items like toothbrushes or razors. Talk with your health care provider about ways to prevent the spread of HIV to others.
- Lab tests, including blood counts, CD4 counts, liver function tests, and physical exams, may be performed while you use enfuvirtide. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Enfuvirtide should be used with extreme caution in CHILDREN younger than 6 years old; safety and effectiveness in these children have not been confirmed.
- The dose of enfuvirtide in CHILDREN is determined based on body weight; they will need to have regular weight checks while they take enfuvirtide.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using enfuvirtide while you are pregnant.
