• Central diabetes insipidus sensitive to vasopressin in infants from 3 months of age, children, adolescents, and adults.
• Symptomatic treatment of short duration of primary nocturnal enuresis in patients (over 5 years of age), caused by nocturnal deficiency of ADH (Antidiuretic Hormone).

• if you suffer from heart failure and other conditions that require treatment with diuretics (medicines that increase urine secretion).

• if you have low sodium levels in the blood (hyponatremia).

Warnings and precautions

Consult your doctor or pharmacist before starting to use Minurin.

Minurin nasal spray solution should only be used in patients where oral formulations are not possible.

If you have primary nocturnal enuresis, be careful to restrict fluid intake by not drinking between 1 hour before administration and until the next morning (at least 8 hours).

Treatment without simultaneous reduction of fluid intake may cause water retention and/or decrease sodium levels in the blood, accompanied by or without symptoms or warning signs (headache, nausea, vomiting, weight gain, and in severe cases, convulsions. (See section 4).

Special care should be taken to avoid decreased sodium levels in the blood in the following cases:

• in children, the dose should be administered under the strict supervision of an adult to ensure correct dosing and avoid accidental overdosing.

diseases characterized by alterations in the proportion of water and electrolytes (calcium, magnesium...) in the blood.

• children, elderly patients, and patients with sodium levels in the blood with values in the lower limit of normality.
• patients at risk of intracranial hypertension.
• Generalized infections, fever, and gastroenteritis (inappropriate ADH secretion syndrome)

Consult your doctor if you are in any of the above patient groups.

Your doctor will monitor your sodium levels in the blood.

If the medicine is used for primary nocturnal enuresis, you should avoid drinking water while swimming and interrupt Minurin during any episode of vomiting and/or diarrhea until your fluid balance returns to normal. Considering the possibility of excess fluid retention, you should monitor that your weight and blood pressure do not increase during treatment. Treatment should be interrupted in case of signs of fluid retention/hyponatremia (decrease in sodium levels in the blood).

Patients with fluid accumulation (edema), scars, or other abnormalities in the nasal mucosa may notice irregular absorption. Consult your doctor in this situation.

Consult your doctor, even if any of the above circumstances have occurred to you.

Using Minurin with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

It is known that some substances such as tricyclic antidepressants, chlorpromazine (a medicine for the treatment of psychiatric problems), carbamazepine (a medicine to prevent seizures), and chlorpropamide (a medicine for the treatment of diabetes mellitus) may increase the risk of fluid retention.

Non-steroidal anti-inflammatory drugs may induce water retention/decrease sodium levels in the blood.

Using Minurin with food and drinks

During treatment for primary nocturnal enuresis, fluid intake should be limited to a minimum and only to satisfy thirst from 1 hour before to 8 hours after administration.

When used for diagnostic purposes, fluid intake should be limited to a minimum and only to satisfy thirst.
