As with any medicine, side effects are possible with interferon beta-1b. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
Common side effects of interferon beta-1b include, but are not limited to:
- Skin reaction at the injection site (such as redness, pain, or burning)
- Flu-like symptoms (such as fever, chills, or muscle aches).
