D-Pressin Nasal Spray 5 ml 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. D-Pressin Nasal Spray 5 ml is also used to manage temporary polyuria (extreme urination) or polydipsia (extreme thirst) after head trauma or surgery in the pituitary gland.

D-Pressin Nasal Spray 5 ml 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, D-Pressin Nasal Spray 5 ml 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. 

D-Pressin Nasal Spray 5 ml is for intranasal use only. Your doctor will decide the dosage depending on your medical condition. The common side effects of D-Pressin Nasal Spray 5 ml 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 D-Pressin Nasal Spray 5 ml, 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 D-Pressin Nasal Spray 5 ml, 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 D-Pressin Nasal Spray 5 ml. 

D-Pressin Nasal Spray 5 ml is a hormone analogue that contains Desmopressin, a synthetic form of Vasopressin (an antidiuretic hormone that controls fluid balance). D-Pressin Nasal Spray 5 ml mimics the natural hormone vasopressin and works by limiting the amount of water eliminated in the urine, thus controlling excessive thirst and urination. D-Pressin Nasal Spray 5 ml is not indicated for the treatment of nephrogenic diabetes insipidus.

Before starting D-Pressin Nasal Spray 5 ml, 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 D-Pressin Nasal Spray 5 ml if you are pregnant, planning to conceive or are a breastfeeding mother. Alcohol consumption may interfere with the working of D-Pressin Nasal Spray 5 ml; hence it is advised to limit or avoid its intake.

• Avoid activities that cause dehydration, such as excessive physical exercise or spending time in the heat.
• Optimal water intake is recommended to prevent dehydration due to excessive urination.

• Regular monitoring of electrolytes is essential to rule out chances of fluid imbalance.
• If you are more frequently urinating than usual, it is advised to consult your endocrinologist to check for any hormonal abnormalities.
• Your doctor may advise kidney functioning tests to monitor for renal impairment.

Diabetes insipidus: It is a condition in which the body fails to control fluid balance, resulting in excessive urination. It is caused due to following: 

A) Central diabetes insipidus: It is caused when the pituitary gland cannot produce enough vasopressin (an antidiuretic hormone that maintains fluid balance). It is characterized by excessive thirst (polydipsia) and excessive urination (polyuria).

B) Nephrogenic diabetes insipidus: Though you make enough vasopressin, your kidneys may not respond to vasopressin that regulates fluid balance.
