What is BETASERON?
BETASERON is a prescription medicine used to reduce the number of relapses in people with relapsing forms of multiple sclerosis (MS). This includes people who have had their first symptoms of multiple sclerosis and have an MRI consistent with multiple sclerosis. BETASERON is similar to certain interferon proteins that are produced in the body. It will not cure your MS but may decrease the number of flare-ups of the disease.
It is not known if BETASERON is safe and effective in children.
Who should not take BETASERON?
Do not take BETASERON if you are allergic to interferon beta-1b, to another interferon beta, to human albumin, or mannitol. See the end of this leaflet for a complete list of ingredients in BETASERON

Instructions for Use
interferon beta-1b (in-ter-feer-on beta-one-be)
Read the Instructions for Use that come with your BETASERON before you start using it and each time you get a refill. There may be new information. This leaflet does not take the place of talking to your healthcare provider about your medical condition or treatment. Before you use BETASERON for the first time, make sure your healthcare provider shows you the right way to use it.
Supplies needed for your BETASERON Injection (See Figure A).
- 1 single-use carton containing:
- A vial of BETASERON
- A pre-filled diluent syringe
- A vial adapter with a 30-gauge needle attached (in the blister pack)
- 2 alcohol prep pads
Step 1: Preparing for Your BETASERON Injection
- Place the supplies you will need on a clean, flat surface in a well-lit area.
- Check the expiration date on the single-use carton to make sure that it has not expired. Do not use it if the medication has expired.
- Wash your hands thoroughly with soap and water.
- Open the single-use carton and take out all the contents. Make sure the blister pack containing the vial adapter is sealed. Check to make sure the plastic cap on the pre-filled diluent syringe is firmly attached.
- Remove the tray from the single-use carton and place it on a flat surface.
- Place the BETASERON vial in the well (vial holder) and place the pre-filled diluent syringe in the U-shaped trough (See Figure B).
Step 2: Mixing BETASERON
- Remove the BETASERON vial from the well (vial holder) and take the cap off the vial.
- Place the vial back into the well (vial holder).
- Use an alcohol prep pad to clean the top of the vial. Move the alcohol prep pad in 1 direction. Leave the alcohol prep pad on top of the vial.
- Peel the label off the blister pack with the vial adapter in it. The vial adapter is sterile. Do not remove or touch the vial adapter.
- Remove the alcohol prep pad from the top of the BETASERON vial. Pick up the vial adapter in the blister pack. Turn over the blister pack keeping the vial adapter inside. Put the adapter on top of the BETASERON vial. Push down on the adapter until it pierces the rubber top of the BETASERON vial and snaps in place (See Figure C). Remove the blister packaging from the vial adapter.
- Twist the plastic cap from the pre-filled diluent syringe. Throw away the plastic cap (See Figure D).
- Keep the vial adapter attached to the vial and remove the vial from the well (vial holder). Be careful not to pull the vial adapter off the top of the vial.
- Connect the pre-filled diluent syringe to the vial adapter by turning clockwise until resistance is felt and the attachment is secure. This forms the syringe assembly (See Figure E).
- Slowly push the plunger of the pre-filled diluent syringe all the way in. This will transfer all of the liquid from the syringe into the BETASERON vial (See Figure F). The plunger may return to its original position after you release it.
- Gently swirl the vial to completely dissolve the white powder of BETASERON. Do not shake. Shaking and even gentle mixing can cause foaming of the medicine. If there is foam, let the vial sit until the foam settles before using it.
- After the powder dissolves, look closely at the solution in the vial. Do not use the solution if it is cloudy or contains particles. It should be clear and colorless.
- Do not use cracked or damaged BETASERON vials. If your vial is cracked or damaged, get a new single-use carton containing a BETASERON vial, pre-filled diluent syringe, vial adapter and 2 alcohol prep pads. Repeat the steps to prepare your BETASERON dose.
- Contact BETAPLUS, the BETASERON patient support program, at 1-800-788-1467 to obtain a replacement product.
Step 3: Preparing the Injection
You have completed the steps to prepare your BETASERON and are ready for the injection. The injection should be given immediately after mixing and allowing any foam in the solution to settle. If you must wait to give yourself the injection, you may refrigerate the solution and use within 3 hours of mixing your BETASERON. Do not freeze.
- Push the plunger in and hold it there; then turn the syringe assembly so that the syringe is horizontal and the vial is on top.
- Slowly pull the plunger back to withdraw all the liquid from the BETASERON vial into the syringe (See Figure G).
- NOTE: The syringe barrel is marked with numbers from 0.25 mL to 1 mL (See Figure H). If the solution in the vial cannot be drawn up to the 1 mL mark, discard the vial and syringe and start over with a new single-use carton containing a BETASERON vial, pre-filled diluent syringe, vial adapter and alcohol prep pads.
- Turn the syringe assembly so that the needle end is pointing up. Remove any air bubbles by tapping the outside of the syringe with your fingers. Slowly push the plunger to the 1 mL mark on the syringe or to the mark that matches the amount of BETASERON prescribed by your healthcare provider (See Figure H). If too much solution is pushed into the vial, repeat Step 3.
- Turn the syringe assembly so that the vial is at the bottom. Remove the vial adapter and the vial from the syringe by twisting the vial adapter. This will remove the vial adapter and the vial from the syringe, but will leave the needle on the syringe (See Figure I).
Step 4: Choosing an Injection Site
- BETASERON (interferon beta-1b) is injected under the skin and into the fat layer between the skin and the muscles (subcutaneous tissue). The best areas for injection are where the skin is loose and soft and away from the joints, nerves, and bones. Do not use the area near your navel or waistline. If you are very thin, use only the thigh or outer surface of the arm for injection.
- Choose a different site each time you give yourself an injection. Figure J shows different areas for giving injections. Do not inject in the same area for 2 injections in a row. Keep a record of your injections to help make sure you change (rotate) your injection sites. You should decide where you will inject BETASERON before you prepare your medicine for injection. If there are any sites that are difficult for you to reach, you can ask someone who has been trained to give the injection to help you.
- Do not inject BETASERON in a site where the skin is red, bruised, infected, or scabbed, has broken open, or has lumps, bumps, or pain. Tell your healthcare provider if you find skin conditions like the ones mentioned here or any other unusual looking areas where you have been given injections.
Step 5: Injecting BETASERON
- Using a circular motion, clean the injection site with an alcohol prep pad, starting at the injection site and moving outward. Let the skin area air dry.
- Remove the cap from the needle. Hold the syringe like a pencil or dart in 1 hand.
- Gently pinch the skin around the site with the thumb and forefinger of the other hand (See Figure K). Insert the needle straight up and down into your skin at a 90° angle with a quick, dart-like motion.
- Slowly push the plunger all the way in until the syringe is empty (See Figure L).
- Remove the needle from the skin. Place a dry cotton ball or gauze pad over the injection site. Gently massage the injection site for a few moments with the dry cotton ball or gauze pad. Throw away the syringe in your puncture-proof disposal container.
- Optional Use of BETACONNECT Autoinjector:
You may also give BETASERON by using the BETACONNECT autoinjector. You should get help with training on the use of the BETACONNECT autoinjector from a healthcare provider before using it for the first time. The BETACONNECT autoinjector should only be used with the syringes that come in the BETASERON packaging. See the Instructions for Use that come with the BETACONNECT autoinjector. For more information, call BETAPLUS, the BETASERON patient support program, at 1-800-788-1467.
Step 6: Disposing of used syringes, needles, and vials
- To prevent needle-stick injury and spread of infection, do not try to re-cap the needle.
- Place used needles, syringes, and vials in a closeable, puncture-resistant container. You may use a sharps container (such as a red biohazard container), hard plastic container (such as a detergent bottle), or metal container (such as an empty coffee can). Do not use glass or clear plastic containers. Ask your healthcare provider for instructions on the right way to throw away (dispose of) the container. There may be state and local laws about how you should throw away used needles and syringes.
- Do not throw used needles, syringes, or vials in your household trash or recycle.
- Throw away any unused medicine. Do not save any unused BETASERON for a future dose.
- Keep the disposal container, needles, syringes, and vials of BETASERON out of the reach of children.
