Precautions

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.

This medicine may cause some people to be anxious, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you or your caregiver notice any of these side effects, tell your doctor right away.

Check with your doctor right away if you have dark urine, persistent loss of appetite, flu-like symptoms, headache, continuing vomiting, general feeling of tiredness or weakness, light-colored stools, right upper stomach pain or tenderness, or yellow eyes or skin. These could be symptoms of a serious liver problem.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

This medicine may lower the number of white blood cells in the blood. This will increase your chance of getting an infection. It can also lower the number of platelets in the blood. Platelets are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

This medicine may cause redness, pain, or swelling at the injection site. Some patients have developed serious skin infection or damage (necrosis), including a permanent depression under the skin at the injection site. Contact your doctor right away if you notice depressed or indented skin, blue-green to black skin discoloration, or pain, redness, or sloughing (peeling) of the skin.

This medicine commonly causes a flu-like reaction, with aching muscles, chills, fever, headaches, joint pain, and nausea. Using your shot at bedtime may allow you to sleep through the symptoms. Your doctor may want you to take a medicine to help control the pain or fever (eg, acetaminophen or ibuprofen). Carefully follow your doctor's instructions about how to prevent or treat these symptoms.

Thrombotic microangiopathy, including thrombotic thrombocytopenic purpura and hemolytic uremic syndrome may occur while you are using this medicine. Tell your doctor right away if you have black, tarry stools, blood in the urine, difficulty with speaking, fever, pinpoint red spots on the skin, seizures, stomach pain, unusual bleeding or bruising, or yellow eyes or skin.

This medicine may cause pulmonary arterial hypertension (high blood pressure in the lungs). Check with your doctor right away if you have trouble breathing or unusual tiredness or weakness.

This medicine contains albumin, which comes from human blood. Some human blood products have transmitted certain viruses to people who have received them, although the risk is low. Human donors and donated blood are both tested for viruses to keep the transmission risk low. Talk with your doctor about this risk if you are concerned. The Avonex® prefilled autoinjector pen and prefilled syringe do not contain albumin which comes from donated human blood.

The tip cap of the Avonex® prefilled syringe contains dry natural rubber (a derivative of latex), which may cause allergic reactions in people who are sensitive to latex. Tell your doctor if you have a latex allergy before you start using this medicine.
