Some people may find injecting their medication to be a daunting task. However, you may find that it gets easier and easier over time, until it doesn't seem very threatening at all. You can use the information below to get more familiar with injections.
BETASERON is injected subcutaneously (just under the skin). Avonex® requires a longer, larger needle, which is injected intramuscularly (into the muscle).1,2

Irritation of the skin following an injection is one form of injection-site reaction. To help reduce the risk of irritation, place a cold cloth or cool pack on the injection site before and after each injection. It is important to rotate injection sites in order to avoid overusing any one area. BETASERON is the only interferon beta with a non-acidic formula. Clinical studies have shown that when compared with Rebif®, there was less pain following an injection of BETASERON.1,3,4,5
Talk to your healthcare professional about any additional steps you can take to help reduce or prevent common side effects.
