Indications 

Nocdurna is a prescribed medication for nocturnal polyuria, a condition characterized by excessive nighttime urine production, causing patients to wake up two or more times during the night to urinate. 

Classified as a vasopressin analog, Nocdurna mimics the action of vasopressin, a natural hormone in the body, to reduce the amount of urine produced by the kidneys during the night. 

Uses and Dosage 

Before taking Nocdurna and with each prescription refill, carefully review its medication guide and patient information leaflet. Inquire with your doctor or pharmacist regarding any questions or uncertainties. 

Nocdurna is available in the form of an orally disintegrating tablet. It should be placed under the tongue and allowed to dissolve completely without chewing or swallowing it whole. Ensure your hands are dry before handling the tablet. 

Typically, Nocdurna is taken once a day, an hour before bedtime. Restrict fluid intake, particularly one hour before and up to 8 hours after taking this medication. 

Furthermore, refrain from consuming beverages containing caffeine or alcohol before bedtime, and make sure to empty your bladder before going to sleep. 

For optimal results, take Nocdurna exactly as directed at a consistent time each day. Do not alter the prescribed dosage, frequency, and duration of intake without consulting your doctor.

• Syndrome of inappropriate antidiuretic hormone secretion (brain disorder)
