Taking Rebif® (interferon beta-1a)

You will be ready to begin taking Rebif to treat your relapsing multiple sclerosis (MS) once your first shipment of Rebif arrives in the mail and you've received injection training from your health care professional and/or an MS LifeLines Field Nurse.

Here are some tips you may find helpful. Although you may not always feel like you need to be on treatment, once disability progresses, it can't be reversed. Rebif is proven to delay the progression of disability, which is the permanent worsening of your neurologic examination over time. That's why it's important to take Rebif as prescribed.

Tips for taking Rebif

Tip 1

Apply a warm cloth or compress to the injection site after injecting.

Tip 2

Bedtime injections are advised, as they may help you to sleep through many of the potential flu-like symptoms.

Tip 3

Remember to store your Rebif somewhere safe and out of the way like a kitchen cabinet so that exposure to light and heat is limited. Room temperature should be less than 77°F. Rebif syringes should never be warmed in the microwave or placed in boiling water.

Tip 4

If you forget an injection and it has been 48 hours since your last injection, take it as soon as you remember. Then, skip a day and take the next one. If it has been more than three days or you have taken the wrong dose, contact your doctor.

Tip 5

Rotate your injection sites, moving between different areas of the arms, legs, abdomen and buttocks. Do not inject in the same place twice in a row, and be sure to wait at least seven days before using a particular spot again. When rotating sites, remember that you can use the entire area of a site (not only a central or focal point). For injection sites, refer to the diagram in the Medication Guide (PDF).

Tip 6

If you are very thin, use only the thigh or the outer surface of the arm for injection. Refer to the diagram in the Medication Guide (PDF).

Tip 7

Some over-the-counter products may help soothe redness, swelling or itching. Aloe vera, topical corticosteroid, anesthetic creams and oatmeal products may all help reduce itching and redness. Check with your health care professional to see what might be right for you.
