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, corticosteroids 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.

Desmopressin is a man-made form of vasopressin. Vasopressin is a substance in your body that helps control how much urine you make. This medication is used by adults who wake up 2 or more times during the night to urinate due to a condition called nocturnal polyuria. This is a condition where your body makes too much urine at night. Other conditions can also cause you to wake up at night to urinate, so you will receive this treatment only after tests by your doctor show you have this condition.

Do not use this medication to treat children who wet the bed at night.
