How should I use BeneFIX?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.

The mixture should appear clear, yellow, or colorless. Do not use the mixed medicine if it has changed colors or has particles in it. Prepare a new kit or call your pharmacist for a new supply of BeneFIX.
Gently swirl but do not shake the medicine bottle when mixing or you may ruin the medicine. Use the injection within 3 hours after mixing your dose.
BeneFIX comes with patient instructions for proper mixing and storage. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
Use a disposable needle only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
