Let's take a minute to talk about your medication. This is Betaseron. It helps treat multiple sclerosis by reducing the number of relapses. Betaseron is given as an injection under the skin. Before injecting it at home, you should demonstrate an injection to your doctor or nurse. You should know how to store the medicine, and how to dispose of needles. Also, be sure to read the Instructions for Use. If you have questions, your doctor or pharmacist can help. You may have flu-like symptoms after each dose. These include feeling tired, or having muscle aches, fever, chills or sweating. These often decrease after a few months of treatment. Until then, your doctor can advise what pain reliever is best for you. If these or other side effects become reasons you want to stop taking Betaseron, please talk to your doctor or pharmacist. As with any medicine, more serious side effects can occur. With Betaseron, these can include injection site reactions. Call your doctor if the injection site has mild tenderness, redness, or other changes that get worse or do not go away in a few days. It could cause liver problems. Call your doctor right away if you have nausea, easy bruising, yellowing skin or eyes, or other unusual changes. To help keep this medicine safe for you, your doctor will order blood tests. You should read the Medication Guide for more information. If you ever have any unexplained changes to your feelings or mood, like depression, anxiety or thoughts of suicide, it could be a side effect of this type of medicine. You should call your doctor right away. Women should talk to their doctors before becoming pregnant or breastfeeding. For best results, take Betaseron exactly as directed by your doctor, and ask about patient support resources.
