Nesiritide

Nesiritide is a prescription medication used to treat patients with severe heart failure who have trouble breathing. Nesiritide belongs to a group of drugs called vasodilators. These work by relaxing blood vessels and increasing the supply of blood and oxygen to the heart while reducing its workload.

Nesiritide is available in an injectable form that is given directly into a vein (IV) by a healthcare professional.

Common side effects of nesiritide include low blood pressure, nausea, headache, and back pain.

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.

Nesiritide falls into category C. There are no well-controlled studies that have been done in pregnant women. Nesiritide should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.
