Tolvaptan: Dosage Guide, Uses for Hyponatremia, and Side Effects

Tolvaptan is an effective medication primarily used to treat hyponatremia, a condition characterized by low sodium levels in the blood. This condition can lead to various serious health issues, including confusion, seizures, and even coma. Understanding the appropriate dosage, uses, and potential side effects of Tolvaptan is crucial for both patients and healthcare providers.

What is Tolvaptan?

Tolvaptan belongs to a class of drugs known as vasopressin receptor antagonists. It works by promoting the excretion of free water through the kidneys, thereby correcting the sodium imbalance in the bloodstream. By blocking the action of vasopressin, Tolvaptan helps to raise serum sodium levels in patients suffering from conditions like the syndrome of inappropriate antidiuretic hormone secretion (SIADH) and congestive heart failure.

The dosage of Tolvaptan can vary depending on the patient’s condition and response to treatment. Below is a general dosage guide:

Condition	Starting Dose	Maximum Dose
