Uses

This medication is used to control and prevent bleeding episodes in people with low levels of factor VIII (hemophilia A). It is also used in these patients before surgery to prevent bleeding. People with low factor VIII levels are at risk for bleeding longer after an injury/surgery and for bleeding inside the body (especially into the joints and muscles). This product contains a man-made form of factor VIII, also called antihemophilic factor. This product is used to temporarily replace the missing factor VIII, a protein (clotting factor) that is normally in the blood, so that the blood can clot and the bleeding can stop.

This medication should not be used to treat von Willebrand disease.

How To Use

This medication is given by injection into a vein as directed by your doctor. The medication may need to be given more slowly over a longer time depending on your dose and how you respond to it.

After first receiving this medication in a hemophilia treatment center or hospital, some patients may be able to give this medication to themselves at home. If your doctor directs you to give this medication at home, read the Patient Information Leaflet available from your pharmacist before you start using this medication and each time you get a refill. Learn all preparation and usage instructions in the product package. Learn how to store and discard needles and medical supplies safely. If you have any questions, ask your health care professional.

If the medication and the solution used to mix it were refrigerated, bring both to room temperature before combining.

Tell your doctor if your condition does not improve or if it worsens.
