FUZEON® :: Preparation and Injection Tips








Preparation Tips

  • Keep things clean. Before working with the vials, wash and dry your hands. Make sure to wipe down all vial tops after removing the vial caps with a fresh alcohol pad and to re-clean these if you accidentally touch the tops. Please do not use the alcohol prep pads that were previously packaged with these medicines. An alternative alcohol prep product or a steriled gauze pad in conjunction with isopropyl alcohol should be used for disinfection.
  • The right stuff. Use the bigger syringe for preparation, and the smaller syringe for FUZEON injection.
  • Slow drip. Slowly inject the sterile water into the FUZEON vial. Let the water drip down the side of the vial.
  • Tap and roll. Lightly tapping and rolling the vial gently between your hands can help FUZEON start to dissolve. Never shake the vial.
  • Dissolve completely. Never inject FUZEON until it is completely dissolved. FUZEON should be clear and without foam.
  • Chill. A mixed vial of FUZEON can be stored in the refrigerator for up to 24 hours—so you can mix 2 at once and set 1 aside for your next dose of FUZEON. Be sure your dose is at room temperature before injecting.
  • Take a turn. Be sure the capped needle is tight by pushing it down slightly while twisting it clockwise.

Injection Tips

  • Bubble trouble. Check the syringe before you inject to make sure there are no bubbles in the liquid.
  • Change it up. Be sure to rotate your injection sites—so that no one spot becomes too tender.
  • Prepare the site. Before you inject, clean the site with a fresh alcohol pad in a circular motion (start in the center and work your way outward).
  • A pinch of skin. FUZEON should be injected into the skin and never into a vein or muscle.
  • Watch out for scar tissue. Avoid injecting FUZEON into hard lumps or scar tissue under the skin.
  • Take it slow. When you inject FUZEON, slowly push the plunger.
  • Take out the trash. When you're done with both syringes, make sure to put them in a Sharps container.

FUZEON Indication

What is FUZEON?

FUZEON is a medicine called an HIV (human immunodeficiency virus) fusion inhibitor. FUZEON is always used with other anti-HIV medicines to treat adults and children ages 6 - 16 years with HIV infection.

FUZEON blocks HIV's ability to infect healthy CD4 cells. When used with other anti-HIV medicines, FUZEON can reduce the amount of HIV in the blood and increase the number of CD4 cells. This may keep your immune system healthy, so it can help fight infection.

FUZEON Contraindication

FUZEON is contraindicated in patients with known hypersensitivity to FUZEON or any of its components

Important Safety Information

What are the possible side effects of FUZEON?

Injection Site Reactions (ISRs)

FUZEON causes injection site reactions.
Almost all people get injection site reactions with FUZEON. Reactions are usually mild to moderate but occasionally may be severe. Reactions on the skin where FUZEON is injected include:

  • itching
  • swelling
  • redness
  • pain or tenderness
  • hardened skin
  • bumps

These reactions generally happen within the first week of FUZEON treatment and usually happen again as you keep using FUZEON. A reaction at one skin injection site usually lasts for less than 7 days. Injection site reactions may be worse when injections are given again in the same place on the body or when the injection is given deeper than it should be (for example, into the muscle).

If you are worried about the reaction you are having, call your healthcare provider to help you decide if you need medical care. If the injection site reaction you are having is severe, call your healthcare provider right away. If you have an injection site reaction, you can discuss with your healthcare provider ways to help the symptoms.

An injection site can get infected. It is important to follow the FUZEON Injection Instructions that come with your medicine to lower your chances of getting an injection site infection.

Call your healthcare provider right away if there are signs of infection at the injection site such as oozing, increasing heat, swelling, redness or pain.

Injection using Biojector® 2000

Shooting nerve pain and tingling lasting up to 6 months from injecting close to large nerves or near joints, and bruising and/or collections of blood under the skin have been reported with use of the Biojector 2000 needle-free device to inject FUZEON. If you are taking any blood thinners, or have hemophilia or any other bleeding disorder, you may be at higher risk of bruising or bleeding after using the Biojector.


Patients with HIV get bacterial pneumonia more often than patients without HIV. Patients with HIV are more likely to get bacterial pneumonia if they have any of the following: a low number of CD4 cells, increased amount of HIV in the blood, intravenous (injected into the vein) drug use, smoking or had experienced lung disease in the past. Patients taking FUZEON with other HIV medicines may get bacterial pneumonia more often than patients not receiving FUZEON. Three patients in the clinical trials who took FUZEON died of pneumonia.

It is unclear if the increased incidence of pneumonia is related to the use of FUZEON. You should contact your healthcare provider right away if you have a cough, fever or trouble breathing.

Allergic Reactions

FUZEON can cause serious allergic reactions. Symptoms of a serious allergic reaction with FUZEON can include:

  • trouble breathing
  • fever with vomiting and a skin rash
  • blood in your urine
  • swelling of your feet

Call your healthcare provider right away if you get any of these symptoms. Discuss with your healthcare provider if you have previously taken FUZEON and experienced any of these reactions.

Other Side Effects

The following side effects were seen more often in patients using FUZEON with their other anti-HIV medicines than in patients not using FUZEON with their other anti-HIV medicines:

  • diarrhea
  • nausea
  • fatigue
  • pain and numbness in feet or legs
  • loss of sleep
  • depression
  • decreased appetite
  • sinus problems
  • enlarged lymph nodes
  • weight decrease
  • weakness or loss of strength
  • muscle pain
  • constipation
  • pancreas problems

These are not all the side effects of FUZEON. For more information, ask your healthcare provider or pharmacist. If you have questions about side effects, ask your healthcare provider.

As with other anti-HIV medicines, FUZEON may strengthen the body's immune response which could uncover hidden infections. Report any new or continuing symptoms to your healthcare provider. Your healthcare provider will tell you what to do and may be able to help you with these side effects.
