BeneFIX and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

BeneFIX falls into category C. No studies have been done in animals, and there are no well-done studies in pregnant women. BeneFIX should be given to a pregnant woman only if clearly needed.

BeneFIX Usage

Take BeneFIX exactly as prescribed.

BeneFIX is given directly into the vein. BeneFIX should be administered as ordered by your healthcare provider. 

You may have to have blood tests done after getting BeneFIX to be sure that your blood level of factor IX is high enough to clot your blood. Call your healthcare provider right away if your bleeding does not stop after taking BeneFIX.

If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of BeneFIX at the same time.
