Tips that may help with injection site discomfort
Rebif may cause redness, pain or swelling at the place where an injection was given. Some patients have developed skin infections or areas of severe skin damage (necrosis) requiring treatment by a doctor. If one of your injection sites becomes swollen and painful or the area looks infected and it doesn't heal within a few days, you should call your doctor. Here are a few tips that may help you with injection-site discomfort.
- Bring the syringe to room temperature. Removing the syringe from your refrigerator 1 to 4 hours before injecting may help to reduce irritation. Keep in mind that Rebif syringes should never be warmed in the microwave or placed in boiling water.
- Clean your injection site beforehand with alcohol swabs. Allow the area to dry before injecting to reduce irritation.
- Rotate your injection sites! Be sure to rotate your sites each time, and don't reuse the same injection spot for at least 7 days. Your treatment journal can help you to keep track of your injections.
- Apply an ice pack to the site for no more than 2 minutes before and after injecting. This can help to minimize discomfort. If ice doesn't help, try a warm compress instead.*
- Massage the area in a circular motion for at least 2 minutes after injection.*
- Monitor your injection site over several days for redness, swelling or tenderness. If the site worsens over time, contact your doctor.
Talk to your doctor about whether you should take an over-the-counter medication for pain or fever reduction before or after taking your dose of Rebif.
- Taking one just before an injection may help to reduce flu-like symptoms.
- These medications are available without a prescription, but they can still have side effects; read dosing instructions carefully.
Find a time of day that works for you.
- Some people inject Rebif before bed, so they can sleep through some of their flu-like symptoms.
- Others find that injecting earlier in the day works best for them.
- Maintain a consistent injection schedule (3 times per week, at least 48 hours apart) as prescribed by your doctor.
