Description

Vasopressin Receptor Antagonist for Low Sodium (Hyponatremia) & Water Retention Management

Hyponat-O 15mg Tablet (Tolvaptan 15mg)

Hyponat-O 15mg Tablet contains Tolvaptan, a selective vasopressin V2-receptor antagonist. It is used in the medical management of low sodium levels in the blood (hyponatremia), especially in conditions like SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion).

This medicine helps the body remove excess free water through urine without significantly losing sodium, thereby helping restore sodium balance in the blood.

Important: Hyponat-O is a prescription medicine and should be used only under strict medical supervision due to the risk of rapid sodium correction.

Clinical Uses

  • Treatment of hyponatremia (low sodium levels)
  • Management of SIADH (Syndrome of Inappropriate ADH)
  • Fluid overload conditions in specific patients
  • Supportive therapy in heart failure (selected cases)
  • Management of autosomal dominant polycystic kidney disease (ADPKD) in some cases

Hyponat-O helps correct water imbalance in the body, improving sodium concentration in blood.

Mechanism of Action

Tolvaptan works by blocking vasopressin V2 receptors in the kidneys. This reduces water reabsorption and increases free water excretion (aquaresis), helping correct diluted sodium levels in the blood.

  • Blocks ADH (vasopressin) action
  • Increases free water excretion
  • Raises serum sodium concentration
  • Helps correct fluid imbalance

Common Uses

  • Low sodium (hyponatremia) treatment
  • SIADH management
  • Fluid imbalance correction
  • Hospital-based electrolyte management
  • Selected kidney and heart conditions (doctor advised)

Directions for Use

  • Take exactly as prescribed by your doctor
  • Usually taken once daily or as directed
  • Can be taken with or without food
  • Do not self-adjust dosage
  • Regular blood sodium monitoring is required

Possible Side Effects

  • Increased thirst
  • Frequent urination
  • Dry mouth
  • Weakness or fatigue
  • Dehydration
  • Rapid sodium correction (risk if misused)
  • Liver enzyme elevation (rare)

Close medical supervision is essential during treatment.

Precautions

  • Use only under specialist supervision
  • Regular liver and sodium monitoring required
  • Avoid dehydration
  • Not for self-medication
  • Use carefully in liver disease patients
  • Store in cool and dry place
