Hyponatremia is a condition where the sodium level in the blood is low, which can lead to dangerous health effects. The most common cause of hyponatremia is drinking too much water. However, it can also occur when a person loses too much salt through sweat or tears. Affected people feel dizzy and faint but are not always aware they are salt deficient until they start feeling sick.

How dangerous is hyponatremia?
Hyponatremia can be acute (new onset) or chronic (persistent). In addition to causing symptoms, chronic hyponatremia may lead to complications such as kidney damage and seizures.
- Acute hyponatremia occurs when there is an imbalance in the amount of water absorbed from food or drink. It causes too much urine production, leading to dehydration. This often occurs after drinking alcohol or excessive sweating due to exercise, known as central pontine myelinolysis (CPM).
- Chronic hyponatremia develops over time due to decreased thirst signals caused by various medical conditions. These medical conditions include diabetes mellitus type 1 (DM1) and Parkinson’s disease. Symptoms vary depending on the cause but include headache; lightheadedness; muscle weakness; slurred speech; confusion; and drowsiness.
What are the symptoms of hyponatremia?
If you drink too much water, your body will not be able to keep up with the amount of fluid. This can lead to hyponatremia and other severe conditions. If you are worried about drinking too much water, talk to your doctor about ways to help manage your thirst in certain situations.
Symptoms of hyponatremia include:
- Headaches
- Dizziness
- Confusion
- Seizures
- Coma
How Tolvaptan works
Tolvaptan is a vasopressin receptor antagonist. This means that it blocks the actions of vasopressin, which is released during dehydration and causes your body to retain water.
Tolvaptan is an effective treatment for hyponatremia. It works by preventing the release of antidiuretic hormone (ADH).
It is used to treat all types of hyponatremia, including:
- Postoperative
- Chronic renal failure
- Congenital central hypovolemic shock
Administration
Tolvaptan is available as an oral tablet and is typically taken once daily, with or without food, for 30 days. At the start of your therapy, you will be administered Tolvaptan at a predetermined time in the hospital.
Read the instructions on your prescription label exactly, and ask your doctor or pharmacist to explain any parts you need help understanding. Tolvaptan should be taken exactly as prescribed. Do not take more or less of it or more frequently than your doctor has suggested.
In conclusion, hyponatremia is a medical condition that occurs when too much sodium is in the blood. It can be treated with Tolvaptan, a medication that works by increasing the amount of sodium in your body. If you have symptoms of hyponatremia, talk to your doctor about how this treatment might work for you.
