Fuzeon contains the active substance enfuvirtide and belongs to a group of medicines called ‘antiretrovirals’.
Fuzeon is used for the treatment of Human Immune deficiency Virus (HIV) - in combination with other antiretroviral medicines in patients infected with HIV.
HIV attacks cells in your blood called CD4 or T-cells. The virus needs to make contact with, and get inside these cells in order for the virus to multiply. Fuzeon helps by preventing this.
If you are not sure, talk to your doctor, pharmacist or nurse before using Fuzeon.
Talk to your doctor, pharmacist or nurse before using Fuzeon if:
In some patients with advanced HIV infection (AIDS) and a history of opportunistic infections, signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is believed that these symptoms are due to a recovery of the body’s immune system. This improvement enables the body to fight infections that may have been present with no obvious symptoms. If you notice any symptoms of infection, please inform your doctor immediately.
In addition to the opportunistic infections, autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also occur after you start taking medicines for the treatment of your HIV infection. Autoimmune disorders may occur many months after the start of treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness beginning in the hands and feet and moving up towards the trunk of the body, palpitations, tremor or hyperactivity, please inform your doctor immediately to seek necessary treatment.
Patients with chronic hepatitis B or C and treated with anti-HIV therapy are at an increased risk for serious liver problems. Speak with your doctor if you have a history of liver disease.
Some patients taking combination anti-HIV medicines may develop a bone disease called osteonecrosis. This is where the bone tissue dies because the blood supply has been lost (death of bone tissue caused by loss of blood supply to the bone).
Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription and herbal medicines. Fuzeon has been shown not to interact with your other anti-HIV medicines or rifampicin (an antibiotic).
You can use Fuzeon with or without food. However, you still need to follow the instructions given in the package leaflets for the other medicines you are taking.
Fuzeon has not been tested for its effect on your ability to drive a car or use tools or machines. If you feel dizzy while using Fuzeon do not drive or use any tools or machines.
Fuzeon contains less than 1 mmol sodium (23 mg) per dose, that is to say it is essentially ‘sodium-free’.
Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
Fuzeon must be given as an injection just below the skin – called a ‘subcutaneous’ injection. Section 7 tells you how to prepare Fuzeon and how to give yourself an injection.
See further instructions on how to use Fuzeon at the end of this leaflet (see Section 7). There you will find instructions on how to prepare Fuzeon and how to give yourself an injection.
If you use more Fuzeon than you should, talk to a doctor or go to a hospital straight away. Take the medicine pack with you.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
This side effect is rare (affects less than 1 in 1,000 people). These signs do not definitely mean you are allergic to this medicine.
The most common side effects (affect more than 1 in 10 people), are problems at the place on your body where you have the injection. You will probably have one or more of the following mild to moderate reactions:
These reactions can appear in the first week of treatment and usually only last for up to 7 days. They generally do not get worse after this time. If you have any of these reactions do not stop using Fuzeon, but talk to your doctor about any concerns you have.
Reactions may be worse when injections are repeated in the same place on the body. They may also be worse when the injection is given deeper than intended (for example, into a muscle). Rarely, you may get an infection at a place where an individual injection was given. To reduce the risk of infection, it is important that you follow the instructions provided in Section 7.
Fuzeon can cause a build-up of a type of protein, called amyloid, under the skin at the injection site. This may feel like lumps under the skin. Please contact your doctor if this occurs.

It may be difficult at first to inject in some places, such as the upper arms. If you need help, ask your partner, a friend, or a family member. You may like to ask someone to come with you to an injection training session with your doctor or nurse.
The syringes supplied with this medicine have a coloured needle protector. This is attached to the needle and covers it after use to lower the risk of the needle accidently pricking another person. Although these syringes have this safety feature, it is still important that you dispose of used syringes properly. Follow the instructions given to you by your doctor, pharmacist or nurse.
The following is a basic, step-by-step guide to injecting your medicine.
1. Get the following things together:
2. Open syringe packs and take off vial caps.
3. Wash hands thoroughly.
4. Clean the tops of the vials.
Draw Up Water for Injections

4. Draw back 1.1 ml of air.
5. Push the syringe needle into the rubber top of the vial of Water for Injections and press the plunger. This injects the air.
6. Gently turn the vial upside down. Make sure the tip of the needle is always below the surface of the Water for Injections to help keep any air bubbles from entering the syringe.
7. Slowly pull back the plunger until the water reaches the 1.1 ml mark. Please be aware that the vial contains more liquid than you need (2 ml); you only have to pull out 1.1 ml to prepare your injection properly.
8. Tap the syringe gently to make any air bubbles rise to the top.
9. Take out the needle from the vial. Make sure you never touch the needle with your fingers or anything else.
