Rebif How to Take

Interferon beta-1a belongs to the group of medications known as immunomodulators. It is a form of a protein that is naturally made by our body's cells to fight infections and tumours. Interferon beta-1a is used to treat relapsing forms of Multiple Sclerosis (MS). It is also used to treat people who have had a single event of MS symptoms, which are likely a first sign of multiple sclerosis. Rebif (Interferon-beta-1a) can also be used to treat people with another type of MS known as secondary progressive MS (SPMS) who are still having relapses. For people who have SPMS, the medication can decrease the frequency of relapses and reduce brain lesions seen on MRI scans.

Multiple sclerosis (MS) is a chronic and disabling disease caused by the body's own defense system attacking and destroying the protective covering (myelin) surrounding nerve fibres. Interferon beta-1a works by slowing down the attack of the body's defense cells on the nerves.

Interferon beta-1a will not cure MS but may decrease the number and severity of flare-ups of the disease, slow the progression of disability, reduce the use of corticosteroid medications (which are often used by people with MS), reduce the number of hospitalizations, and decrease the number and volume of active brain lesions (damaged areas of the brain) seen on MRI scans.

Rebif (Interferon-beta-1a) may be available under multiple brand names and/or in several different forms. Any specific brand name of Rebif (Interferon-beta-1a) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Rebif (Interferon-beta-1a) may not be used for all of the conditions discussed here.

Your doctor may have suggested Rebif (Interferon-beta-1a) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are being given Rebif (Interferon-beta-1a), speak to your doctor. Do not stop using Rebif (Interferon-beta-1a) without consulting your doctor.

Do not give Rebif (Interferon-beta-1a) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use Rebif (Interferon-beta-1a) if their doctor has not prescribed it.

Rebif Dosage

The recommended dose of interferon beta-1a for relapsing-remitting forms of multiple sclerosis (MS) is 44 µg injected under the skin 3 times per week. Your doctor may reduce this dose to 22 µg injected under the skin 3 times per week if you are experiencing unacceptable side effects.

The recommended dose of interferon beta-1a for a single clinical event of multiple sclerosis (MS) is 44 µg injected under the skin 3 times per week.

In order to reduce side effects when first starting treatment, it is recommended the dose be gradually increased as follows:

  • 20% of the recommended dose during the first 2 weeks of treatment,
  • 50% of the recommended dose during the third and fourth weeks of treatment, and
  • the full dose from the fifth week onwards.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way you are using the medication without consulting your doctor.

Interferon beta-1a is used with the guidance and supervision of a doctor. Your doctor or nurse may ask you to inject the medication at home once they have instructed you and are certain that you won't have any problems with doing it at home. Do not attempt to prepare or inject Rebif (Interferon-beta-1a) on your own until you completely understand how to mix and inject a dose.

It is important that Rebif (Interferon-beta-1a) be used exactly as prescribed by your doctor. If you forget to take a dose, skip the missed dose and continue with your regular dosing schedule. Do not inject a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Interferon beta-1a should be stored in the refrigerator. If storing in the refrigerator, allow the medication to reach room temperature before injecting it. Alternatively, it may be stored for a limited period of time (up to 30 days) at room temperature.

Use a different injection site for each dose. You should avoid injecting Rebif (Interferon-beta-1a) into an area of skin that is sore, red, infected, or otherwise damaged. If you are having difficulty giving yourself injections, talk to your health care provider.

Please refer to the package insert (the written instructions that come in the medication package) for complete instructions on using Rebif (Interferon-beta-1a). Always wash your hands before preparing the medication and after you have used it.

Protect Rebif (Interferon-beta-1a) from light, moisture, freezing, and high temperatures. Keep Rebif (Interferon-beta-1a) out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
