Tolvaptan 15mg

Tolvaptan 15mg — Uses and Benefits

Tolvaptan is mainly used to correct low sodium levels in the blood and to manage certain kidney conditions.

WHAT THIS MEDICINE IS USED FOR

• Treating hyponatremia (low blood sodium) due to conditions like SIADH, heart failure, or liver cirrhosis
• Slowing the loss of kidney function in adults with autosomal dominant polycystic kidney disease (ADPKD) who are at risk of rapid progression

HOW IT WORKS

• Blocks vasopressin V2 receptors in the kidney
• This reduces water reabsorption, causing the body to pass more water without losing much salt
• This helps raise blood sodium levels and in ADPKD reduces cyst growth

WHAT IT IS NOT USED FOR

• Not used for general dehydration
• Not a treatment for high blood pressure
• Not used for routine fluid retention or swelling unrelated to the above conditions
• Not for use in emergency or very severe hyponatremia requiring hospital-based correction without close monitoring
• Not to be self-started without a doctor's supervision, as it needs monitoring of blood sodium and liver function
