Warnings:

Desmopressin can rarely cause a low level of sodium in the blood (hyponatremia), which can be serious or even fatal. Drinking too much liquid, using certain medications (such as "water pills"/diuretics including furosemide, glucocorticoids such as prednisone), being 65 years or older, or having certain medical conditions may increase the risk of low sodium in the blood. Lab tests (such as urine tests, sodium blood levels) must be done before you start using this medication and while you are using it. Keep all medical and lab appointments.

Tell your doctor right away if you develop symptoms of low sodium in the blood, such as nausea, vomiting, headache, muscle weakness/cramps, unusual tiredness, unusual drowsiness, dizziness, restlessness, mental/mood changes including confusion/irritability.

Get medical help right away if you have any very serious side effects, including seizure or trouble breathing.

Uses

Desmopressin is used in people with certain bleeding problems (hemophilia A, type 1 von Willebrand's disease) to control bleeding caused by surgery, injuries, or heavy menstrual periods. This medication is a man-made form of a certain substance in the body called vasopressin that helps with normal blood clotting.
