Avonex (Interferon beta-1a) is used to treat relapsing multiple sclerosis (MS). This medication will not cure MS, it will only decrease the frequency of relapse symptoms. It is made from human proteins. Common side effects include pain, swelling, or redness at the injection site. Flu-like symptoms such as headache, fatigue, fever, chills, and muscle aches may occur when you first start this medication. These symptoms usually last about a day after the shot and improve or go away after a few months of continued use. Some patients using interferon medications have become depressed or had suicidal thoughts. Tell your doctor immediately if this occurs.
The recommended dosage of Avonex is 30 mcg injected intramuscularly once a week. This medication is intended for use under the guidance and supervision of a physician. Patients may self-inject only if their physician determines it is appropriate and after proper training in intramuscular injection technique. Avonex may interact with acetaminophen, cancer medications, tuberculosis medications, birth control pills or hormone replacement therapy, methotrexate, arthritis medications, antibiotics, HIV/AIDS medications, cholesterol medications, ACE inhibitors, NSAIDs (non-steroidal anti-inflammatory drugs), or seizure medications drug interactions. Tell your doctor all medications you are taking. Avonex is not recommended for use during pregnancy. It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.
