Cautions

Before using desmopressin, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney disease, heart problems (such as blocked blood vessels, heart failure), high blood pressure, conditions that may increase your risk of fluid/mineral imbalance (such as cystic fibrosis), the urge to drink too much water without being thirsty, a low level of sodium in the blood (hyponatremia), bleeding/clotting problems.

If you become dehydrated, your doctor will correct that condition first before starting treatment with desmopressin.

Limit alcohol because it can interfere with how well desmopressin works.

Changes inside the nose (such as scarring, swelling, congestion, or blockage) may affect how well desmopressin is absorbed. Tell your doctor if you have any of these changes inside the nose because your doctor may need to adjust your treatment.

Tell the doctor right away if you develop any illness that can cause water/mineral imbalance (including fever, diarrhea, vomiting, and infections such as the flu) or if you experience conditions that require drinking more fluids (for example, exposure to very hot weather, strenuous exercise, heavy sweating). The doctor may need to stop or adjust desmopressin treatment, especially in children and older adults.

Children may be more sensitive to the side effects of this drug, especially water/mineral imbalance and a low level of sodium in the blood.

Older adults may be at greater risk for water/mineral imbalance and a low level of sodium in the blood while using this drug.
