Brand Names: Raptiva
What is Raptiva?
Raptiva is a man-made form of a protein similar to human antibodies. Efalizumab is made to target and destroy only certain cells in the body. This may help to protect healthy cells from damage.
Raptiva is used to treat plaque psoriasis (raised, silvery flaking of the skin) in adults.
Raptiva may also be used for other purposes not listed in this medication guide.
Raptiva increases the risk of serious infections, including a viral infection of the brain that can lead to disability or death. This risk is higher if you have a weak immune system or are receiving certain medicines. Call your doctor right away if you have symptoms such as change in your mental state, problems with speech or walking, or decreased vision. These symptoms may start gradually and get worse quickly.
During your Raptiva treatment, it is extremely important that your doctor check you every 3 to 6 months to make sure you are not developing any signs of serious infection. Do not miss any scheduled visits to your doctor. You should also call your doctor right away if you develop signs of infection such as fever, chills, sore throat, flu symptoms, easy bruising or bleeding (nosebleeds, bleeding gums), loss of appetite, nausea and vomiting, mouth sores, or unusual weakness.
Before using Raptiva, tell your doctor about all other medications you are using, especially other psoriasis medications or phototherapy, or drugs that weaken your immune system such as cancer medicine, steroids, and medicines to prevent rejection of a transplanted organ.

How should I use Raptiva?
Use Raptiva exactly as prescribed by your doctor. Do not use it in larger amounts or for longer than recommended. Follow the directions on your prescription label.
This medication comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
Raptiva is given as an injection under the skin. Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to inject your medicine at home. Do not self-inject Raptiva if you do not fully understand how to give the injection and properly dispose of used needles and syringes.
Raptiva is usually given once per week. Try to use the medicine on the same day each week.
Use a different place on your stomach, thigh, buttocks, or upper arm each time you give yourself an injection. Your care provider will show you the places on your body where you can safely inject the medication. Do not inject into the same place two times in a row.
Raptiva is a powder medicine that must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medication.
Do not shake the mixed medicine. Vigorous shaking can cause the mixture to foam. Do not draw your Raptiva dose into a syringe until you are ready to give yourself an injection. Do not use the medication if it has changed colors or has any particles in it. Call your doctor for a new prescription.
Each single-use vial (bottle) of this medicine is for one use only. Throw away the vial after one use, even if there is still some medicine left in it after injecting your dose.
Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.
A day or two after using your first dose of Raptiva, you may have nausea, vomiting, muscle pain, and/or a headache. Call your doctor if these effects become severe.

Call your doctor if your symptoms do not improve, or if they get worse while using Raptiva. Your psoriasis may get worse after you stop using Raptiva for any reason. Your doctor may want to keep checking to make sure your psoriasis does not get worse. Do not miss any follow-up visits.
Store Raptiva in its original carton in the refrigerator, protected from light. Do not freeze. If you have mixed your medicine and cannot use it right away, keep the mixture at room temperature and use it within 8 hours. Check to make sure the mixture is still clear or pale yellow and does not contain any particles.
