Patient’s Leaflet

What is it and how is it used?

Rebif belongs to a class of medicines known as interferons. These are natural substances that transmit messages between cells. Interferons are produced by the body and play an essential role in the immune system. Through mechanisms that are not totally understood, interferons help to limit the damage of the central nervous system associated with multiple sclerosis.

Rebif is a highly purified soluble protein that is similar to the natural interferon beta that is produced in the human body.

Rebifis used for the treatment of multiple sclerosis. It has been shown to reduce the number and the severity of relapses and to slow the progression of disability.

How to inject Rebif
- Choose an injection site. Your doctor will advise you on the possible injection sites (good sites include the upper thighs and the lower abdomen). Hold the syringe like a pencil or dart. It is recommended that you keep track of and rotate your injection sites, so that one area is not injected too frequently in order to minimise the risk of injection site necrosis.

- Wash your hands thoroughly with soap and water.
- Remove the Rebif syringe from the blister pack by peeling back the plastic covering. - Before the injection use an alcohol wipe to clean the skin at the injection site. Let the skin dry. If a bit of alcohol is left on the skin, you may get a stinging sensation.

Gently pinch the skin together around the site to lift it up a bit. Resting your wrist on the skin near the site, stick the needle at a right angle straight into the skin with a quick, firm motion. Inject the medicine by using a slow, steady push push the plunger all the way in until the syringe is empty. Hold a swab on the injection site. Remove the needle from the skin.

Gently massage the injection site with a dry cotton ball or gauze. Dispose of all used items once you have finished your injection, immediately discard the syringe in an appropriate disposal unit.
