Drug Description


DDAVP MELT is a prescribed medication indicated for children aged 5 and above experiencing primary nocturnal enuresis (PNE), a condition characterized by bedwetting during nighttime. 

Moreover, DDAVP MELT is prescribed to manage or prevent excessive urination, intense thirst, and fluid loss linked to Diabetes Insipidus (impaired kidney water retention) after head trauma and pituitary gland surgery. 

DDAVP MELT is a synthetic substitute for vasopressin, a hormone produced by the pituitary gland that controls water balance in the body. By replenishing depleted vasopressin levels, it helps regulate urine production, alleviate excessive thirst and urination associated with specific conditions, and prevent dehydration. 

Uses and Dosage 

Before taking DDAVP MELT, carefully read the accompanying medication guide and patient information leaflet. If you have any questions or need additional information, consult your doctor or pharmacist for guidance. 

The prescribed dosage of this medication may differ for each person, contingent on their medical condition and their response to the treatment. 

DDAVP MELT comes as a sublingual disintegrating tablet that melts when placed under the tongue. 

Ensure your hands are dry before removing the tablet from its packaging. Place the tablet under your tongue and allow it to dissolve. Refrain from chewing or swallowing the tablet whole. 

For the treatment of bedwetting, this medication is usually taken once daily, one hour before bedtime. Restrict your child’s fluid intake after dinner, particularly within one hour of bedtime and until at least 8 hours after taking the medication in the morning. 

For the treatment of diabetes insipidus, this medication is usually taken 2 to 3 times a day. 

Restrict fluid intake while taking this medication and consult your doctor for specific guidelines. Promptly inform your doctor if you consume more fluids than prescribed. 

To achieve the best outcomes, take DDAVP MELT exactly as directed, at the same times each day. Do not alter the prescribed dosage, frequency, and duration of treatment without your doctor’s approval. 

Notify your doctor if your condition fails to improve or the effectiveness of this medication diminishes.
