• Administration: Desmopressin nasal spray should be administered directly into the nostrils. Before use, shake the bottle gently to ensure the medication is properly mixed. Follow the prescribed dosage as directed by your healthcare provider.
  • For bedwetting or diabetes insipidus: Spray the prescribed amount into one or both nostrils, usually at bedtime or as directed by your healthcare provider.
  • For bleeding disorders: The dosage may vary, and your healthcare provider will give specific instructions, typically using the nasal spray 1 to 2 hours before a surgical procedure.
• Proper Technique: When using the nasal spray, ensure that you tilt your head slightly forward, insert the nozzle into one nostril, and spray while inhaling gently. Avoid sniffing too hard to allow the medication to be absorbed effectively through the nasal mucosa.
• Storage: Store the nasal spray at room temperature, away from direct heat or sunlight. Keep the bottle tightly closed to prevent contamination.

• Water Retention: Desmopressin works by stimulating the kidneys to reduce the amount of urine produced, mimicking the action of the naturally occurring hormone vasopressin. When administered as a nasal spray, Desmopressin is absorbed through the nasal mucosa and acts on the kidneys to help them retain water, thus reducing excessive urination, which is a common issue for people with diabetes insipidus and nocturnal enuresis.
• Clotting Factor Release: In individuals with certain bleeding disorders, Desmopressin helps release clotting factors, including von Willebrand factor and factor VIII, which are necessary for proper blood clotting. This can help control bleeding episodes and prevent excessive bleeding during surgery or injury.

• Common Side Effects:
  • Headache
  • Nasal irritation or congestion
  • Dry mouth or throat
  • Stomach upset or nausea
• Serious Side Effects:
  • Hyponatremia (Low Sodium Levels): This is one of the most significant risks when using Desmopressin, especially if the medication is taken in excessive amounts. Symptoms of hyponatremia may include headache, nausea, vomiting, confusion, and in severe cases, seizures or coma.
  • Water Retention: Excessive water retention can cause swelling and increase the risk of low sodium levels. It is essential to monitor fluid intake and follow the prescribed dosage carefully.
• Allergic Reactions: Although rare, some people may experience an allergic reaction to Desmopressin, including swelling, rash, or difficulty breathing. Seek medical attention if these symptoms occur.

• Risk of Low Sodium: Desmopressin can lead to water retention and dilute the sodium in your body, which could result in a dangerous condition called hyponatremia. Patients should avoid drinking excessive amounts of fluids while on this medication. If you experience symptoms like headache, nausea, or confusion, contact a healthcare provider immediately.
• Kidney and Heart Issues: Desmopressin should be used cautiously in individuals with kidney disease, heart disease, or conditions that cause fluid imbalance. Regular monitoring may be required to ensure the medication is working properly and to check for side effects.
• Pregnancy and Breastfeeding: Desmopressin should be used during pregnancy only if clearly needed and prescribed by a doctor. The safety of Desmopressin during breastfeeding has not been established, so it should be used with caution in these cases.

• Diuretics: Combining Desmopressin with diuretics (e.g., furosemide) can lead to dehydration and an increased risk of low sodium levels (hyponatremia).
• NSAIDs: The combination of Desmopressin and NSAIDs (e.g., ibuprofen) may increase the risk of water retention and electrolyte imbalances.
• Antidepressants (SSRIs): Certain antidepressants may heighten the effects of Desmopressin, raising the risk of fluid imbalance, particularly low sodium levels.

• For Nocturnal Enuresis:
  • Adults and children over 6 years: 0.2 mg (one spray in one nostril) at bedtime. The dose may be increased up to 0.4 mg (two sprays) per night based on response.
• For Diabetes Insipidus:
  • Adults: 10 to 40 mcg (1-2 sprays in each nostril), 1 to 3 times a day depending on the severity of the condition.
• For Bleeding Disorders:
  • Typically, 150 to 300 mcg (1-2 sprays in each nostril) 1 to 2 hours before surgery or as directed by the healthcare provider.

Each patient’s dosage may vary based on their condition and medical history, so always follow the prescribed instructions provided by your healthcare provider.
