Extavia How to Take

Interferon beta-1b 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-1b is used to treat relapsing forms of Multiple Sclerosis (MS).

Multiple sclerosis (MS) is a chronic and disabling disease caused by the body's own defense system attacking and destroying the protective covering known as myelin that surrounds nerve fibres. Interferon beta-1b works by slowing down the attack of the body's defense cells on the nerves. Interferon beta-1b is used to reduce the frequency of exacerbations (worsening of symptoms) in people suffering with relapsing-remitting multiple sclerosis.

Extavia (Interferon-beta-1b) is also used to delay the onset of MS in people who have experienced a single flare-up of symptoms and have changes that suggest MS in their magnetic resonance imaging (MRI) scans.

Extavia (Interferon-beta-1b) can also be used to treat people with another type of MS known as SPMS (secondary progressive MS) who are still having relapses. In people with SPMS, the medication can decrease the frequency of relapses and reduce brain lesions seen on MRI scans.

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

Your doctor may have suggested Extavia (Interferon-beta-1b) 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 Extavia (Interferon-beta-1b), speak to your doctor. Do not stop using Extavia (Interferon-beta-1b) without consulting your doctor.

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

Your privacy is important. That's why we send your medication inside a plain delivery box so no one will know what's inside.

Extavia Dosage

The recommended adult dose of interferon beta-1b is 0.25 mg (8 MIU) injected subcutaneously (under the skin) every other day. In some cases, the doctor may prescribe a lower dose to start, and gradually increase the dose until the recommended adult dose has been reached.

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 that you are using the medication without consulting your doctor.

Interferon beta-1b 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 Extavia (Interferon-beta-1b) on your own until you completely understand how to mix and inject a dose.

Use a different injection site for each dose. You should avoid injecting Extavia (Interferon-beta-1b) 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.

It is important that Extavia (Interferon-beta-1b) be taken exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible. Your next injection should be given about 48 hours after the first dose. Do not take 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.

See the package insert for instructions on choosing the injection site, preparing the injection, and injecting the medication. Before mixing, interferon beta-1b should be kept at temperatures between 2°C and 25°C. Excursions between 25°C and 30°C are permitted as long as they do not exceed a maximum of 30 days. Do not freeze. After mixing, the vial or syringe containing the medication should be kept in a refrigerator and used within 3 hours.

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