Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For interferon beta-1a, the following should be considered:

Allergies - Tell your doctor if you have ever had any unusual or allergic reaction to interferons or human albumin. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy - Interferon beta-1a has not been studied in pregnant women. However, studies in animals have shown that interferon beta-1a may cause miscarriages. Be sure your doctor knows if you are pregnant or if you may become pregnant.

Breast-feeding - It is not known whether interferon beta-1a passes into breast milk. Because of the possibility of serious unwanted effects in the nursing infant, it is important that you discuss the use of this medicine with your doctor if you wish to breast-feed.

Children - Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of interferon beta-1a in children with use in other age groups.

Older adults - Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of interferon beta-1a in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults.

Other medicines - Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Other medical problems - The presence of other medical problems may affect the use of interferon beta-1a. Make sure you tell your doctor if you have any other medical problems, especially:

  • Heart disease - Some side effects of this medicine may be harmful to patients with serious heart problems
  • Mental depression or thoughts of suicide - This medicine may make the condition worse
  • Seizure disorder - The risk of seizures may be increased
