What is Natrecor?

Natrecor (nesiritide) relaxes and dilates blood vessels, lowering blood pressure.

Natrecor is used to improve breathing in people with sudden severe heart failure.

Natrecor is given by intravenous (IV) injection and infusion.

Important Information

You should not use Natrecor if you have very low blood pressure, or if your heart cannot pump blood properly.

Before you receive Natrecor, tell your doctor if you have kidney disease.

Tell your doctor about any heart problems you currently have or have had in the past. There are certain heart conditions that could make it dangerous for you to receive Natrecor.

Before taking this medicine

You should not be treated with Natrecor if you are allergic to nesiritide, or if:

  • your heart cannot pump blood properly; or

  • you have very low blood pressure.

Tell your doctor if you have ever had kidney disease.

Tell your doctor if you are pregnant. It is not known whether nesiritide will harm an unborn baby. However, heart failure can get worse during pregnancy and may cause complications such as premature birth, stillbirth, or death of the mother. The benefit of treating heart failure may outweigh any risks to the baby.

It is not known whether nesiritide passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How is Natrecor given?

Natrecor is given as an infusion into a vein. A healthcare provider will give you this injection.

This medicine must be given slowly, and the infusion may be given continuously for up to 96 hours.

Your blood pressure and other vital signs will be watched closely.
