How should I use RiaSTAP?

RiaSTAP is given as an injection through a needle placed into a vein. Your doctor will perform blood tests to make sure you do not have conditions that would prevent you from safely using this medicine.

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

RiaSTAP is injected into a vein through an IV. You may be shown how to use an IV at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.

RiaSTAP is a powder medicine that must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.

Do not mix RiaSTAP with any other medicines, or give other medicines through the same IV line.

RiaSTAP contains no preservative. Once you have pierced the rubber top of a vial with a needle, you must use that vial right away or throw it away.

Do not shake the medication bottle or you may ruin the medicine. Prepare your dose only when you are ready to give an injection. The mixture should be clear or slightly colored. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.

Mixed medicine must be used within 24 hours if you keep it at room temperature.

Each single-use vial (bottle) of this medicine is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.

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.

Tell your doctor if you have any changes in weight. RiaSTAP doses are based on weight, and any changes may affect the dose.

You may need frequent medical tests to help your doctor determine how long to treat you with RiaSTAP.
