What it is and what it is used for

for Desmopressin tablets are round, white tablets. They contain the active ingredient desmopressin acetate hydrate. Desmopressin tablets are used for the treatment of:

• vasopressin-sensitive cranial diabetes insipidus (a disease causing the passing of excessive urine because not enough ADH [a hormone] is produced). Vasopressin-sensitive means that the disease can be treated with Desmopressin.
• post-hypophysectomy polyuria/polydipsia (frequent urination or excessive drinking following the removal of the pituitary gland).
• primary nocturnal enuresis (bed-wetting in a person who has never developed night-time bladder control). 2 Before you take Desmopressin Do not take Desmopressin tablets (and talk to your doctor) if you:
• are allergic (hypersensitive) to Desmopressin or any of the other ingredients of Desmopressin tablets (see list of ingredients in Section 6). An allergic reaction may include rash, itching, difficulty breathing or swelling of the face, lips, throat or tongue
• have heart disease or another condition that needs treatment with a diuretic (water tablet)
• have abnormal blood pressure and need treatment for bed-wetting
• drink a lot of fluid because of a mental condition

• abuse alcohol
• are over the age of 65 and need treatment for bed-wetting
• have low sodium levels
• have symptoms of ADH (antidiuretic hormone) disorder
• have an inherited sugar disorder (galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption) Take special care with Desmopressin tablets (and talk to your doctor) if you:
• have a kidney disorder (you may need a larger dose)
• have heart disease
• have cystic fibrosis Bed Wetting If you are being treated with Desmopressin for bed-wetting, your fluid intake must be limited from 1 hour before until 8 hours after taking the tablets. You should avoid drinking water while swimming and you should stop taking Desmopressin if you are vomiting or have diarrhoea until your fluid balance is back to normal. Fluid/Salt Disorder You must be careful not to drink too much fluid if you have a condition that causes a fluid or salt disorder or if you are at risk of increased intracranial pressure (pressure on the brain). It is important to monitor body weight and blood pressure during treatment with Desmopressin.

• loperamide (for diarrhoea) It may still be all right for you to be given Desmopressin and your doctor will be able to decide what is suitable for you.
