Interferon Beta-1b Injection

About your treatment

Your doctor has ordered interferon beta-1b to treat multiple sclerosis (MS). The drug will be injected under the skin (subcutaneously) every other day for up to 2 years. Your health care provider will show you what to do.

Interferon beta-1b, a synthetic version of substances naturally produced by the body, helps to reduce inflammation caused by MS.

Your health care provider (doctor, nurse, or pharmacist) may measure the effectiveness and side effects of your treatment using laboratory tests and physical examinations. It is important to keep all appointments with your doctor and the laboratory. The length of treatment depends on how you respond to the medication.


Before administering interferon beta-1b,

  • tell your doctor and pharmacist if you are allergic to interferon beta-1b or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially antibiotics and vitamins.
  • tell your doctor if you have or have ever had kidney disease or diabetes.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking interferon beta-1b, call your doctor.
  • plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Interferon beta-1b may make your skin sensitive to sunlight.

Administering your medication

Before you administer interferon beta-1b, look at the solution closely. It should be clear and free of floating material. Observe the solution container to make sure there are no leaks. Do not use the solution if it is discolored, if it contains particles, or if the container leaks. Use a new solution, but show the damaged one to your health care provider.

It is important that you use your medication exactly as directed. Do not change your dosing schedule without talking to your health care provider.

Side effects

Although side effects from interferon beta-1b are not common, they can occur. Interferon beta-1b sometimes causes a flu-like reaction with fever, chills, sweating, muscle aches, and general discomfort. These effects may last 10 days or longer. Tell your health care provider if any of these problems continues or worsens.

Tell your health care provider if any of these symptoms are severe or do not go away:

  • diarrhea
  • constipation
  • headache
  • fatigue
  • laryngitis
  • sinus pain
  • bladder irritation
  • weight gain

If you experience any of the following symptoms, call your health care provider immediately:

  • inflammation, pain, irritation, and skin problems at the injection site
  • vaginal bleeding or spotting between menstrual cycles
  • heart palpitations or rapid heart rate
  • shortness of breath
  • depression
  • anxiety
  • mood changes

Storing your medication

  • Your health care provider probably will give you a several-day supply of interferon beta-1b at a time and provide you with directions on how to prepare each dose. Store the vials in the refrigerator.
  • Take your next dose from the refrigerator 1 hour before using it; place it in a clean, dry area to allow it to warm to room temperature.
  • You must use a prepared dose within 3 hours. Avoid shaking the vial. Use a vial only once, and do not reenter a needle into the vial.
  • Do not allow interferon beta-1b to freeze.

Store your medication only as directed. Make sure you understand what you need to store your medication properly.

Keep your supplies in a clean, dry place when you are not using them, and keep all medications and supplies out of reach of children. Your health care provider will tell you how to throw away used needles, syringes, tubing, and containers to avoid accidental injury.

In case of emergency/overdose

In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.

Signs of infection

If you are receiving interferon beta-1b under your skin, you need to know the symptoms of a catheter-related infection (an infection where the needle enters your vein or skin). If you experience any of these effects near your intravenous catheter, tell your health care provider as soon as possible:

  • tenderness
  • warmth
  • irritation
  • drainage
  • redness
  • swelling
  • pain
