Minirin Nasal Spray belongs to the class of 'antidiuretics', primarily used as replacement therapy in central cranial diabetes insipidus, a condition in which the body fails to control water balance, resulting in excessive urination. Minirin Nasal Spray is also used to manage temporary polyuria (extreme urination) or polydipsia (extreme thirst) after head trauma or surgery in the pituitary gland.

Minirin Nasal Spray contains Desmopressin, a human-made form (synthetic) of Vasopressin. Vasopressin is an antidiuretic (that controls fluid balance) hormone synthesized in the hypothalamus of the pituitary gland. When your body cannot produce enough vasopressin, Minirin Nasal Spray is given to replace a low level of vasopressin. It mimics the natural hormone vasopressin and works by reabsorbing water from the kidneys, which controls excessive thirst and urination. Thus, it prevents dehydration. 

Minirin Nasal Spray is for intranasal use only. Your doctor will decide the dosage depending on your medical condition. The common side effects of Minirin Nasal Spray include conjunctivitis/red eyes, weakness, headache, nasal congestion/stuffy nose, rhinitis/runny nose, nose bleeds, nausea, upset stomach, abdominal pain, and flushing (sense of warmth) of the face. These side effects may not occur in every patient using this medication and gradually resolve over time. If the side effects persist longer or worsen, please seek a doctor's advice.

Before starting Minirin Nasal Spray , let your doctor know if you have any medical history of severe kidney disease or hyponatremia (low sodium levels in your body), excessive fluid intake, high blood pressure, heart problems/failure, swelling or scarring of the nasal lining, and illnesses that cause fluid/mineral imbalance. While using Minirin Nasal Spray , avoid drinking large amounts of fluid, including alcohol, since it could lead to the build-up of water in the body. Pregnant and breastfeeding women should consult their doctor before using Minirin Nasal Spray . 

Minirin Nasal Spray is a hormone analogue that contains Desmopressin, a synthetic form of Vasopressin (an antidiuretic hormone that controls fluid balance). Minirin Nasal Spray mimics the natural hormone vasopressin and works by limiting the amount of water eliminated in the urine, thus controlling excessive thirst and urination. Minirin Nasal Spray is not indicated for the treatment of nephrogenic diabetes insipidus.

Before starting Minirin Nasal Spray , let your doctor know if you have any history of allergic reactions to antidiuretic hormones, severe kidney disease, hyponatremia (low sodium levels in your body), excessive fluid intake, high blood pressure, heart failure, illnesses that cause fluid/mineral imbalance (cystic fibrosis), and fluid retention. Please consult your doctor before starting Minirin Nasal Spray if you are pregnant, planning to conceive or are a breastfeeding mother. Alcohol consumption may interfere with the working of Minirin Nasal Spray ; hence it is advised to limit or avoid its intake.
