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 human 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.

How to use Hemofil M Vial

This medication is given by injection into a vein as directed by your doctor, usually over 5 to 10 minutes. 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 product information 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. If you have any questions, ask your health care professional.

If the medication and the solution used to mix it have been refrigerated, bring both to room temperature before combining. After adding the solution to the powder, some brands of this medication may require you to shake the vial for 10 to 15 seconds before gently swirling the vial to completely dissolve the powder. Other brands do not recommend shaking the vial. Ask your pharmacist about the proper way to mix your medication. Before using this product, check it visually for particles or discoloration. If either is present, do not use the liquid. Use right away (See also Storage).
