Complete patient guide for uses, dosage, side effects, and safety information
Quick Facts
What Is Minirin Melt Used For?
Minirin Melt is a medication that contains desmopressin, a synthetic form of vasopressin, which helps reduce urine production in the kidneys.
Primary Uses
It is primarily used to treat primary nocturnal enuresis (bedwetting) in patients over 6 years old and cranial diabetes insipidus.
How It Works
Desmopressin mimics the action of vasopressin, reducing the amount of urine produced by the kidneys.

How to Take Minirin Melt
Minirin Melt is taken sublingually, meaning it should be placed under the tongue where it dissolves quickly.
Dosage Instructions
For bedwetting, the usual starting dose is one 120 mcg wafer at bedtime, which may be increased to two wafers (240 mcg) if necessary. For cranial diabetes insipidus, doses can be up to 120 mcg three times daily, adjusted based on individual needs.
What If You Miss a Dose?
If you miss a dose for bedwetting, skip it and take the next dose at the usual time. For cranial diabetes insipidus, take the next dose as soon as you remember, but do not double the dose.
Important: Never take a double dose to make up for a missed dose.
