Tolvaptan is not used to treat jaundice or hepatic encephalopathy. It may sometimes be used to treat low sodium (hyponatraemia) in patients with liver cirrhosis and ascites. However, a sodium level of 107 is dangerously low, and using it in this situation carries a significant risk of liver injury. You need urgent care in a hospital setting under the supervision of a specialist.

Frequent low sodium usually happens when your body holds too much water, you take certain medicines, or you have hormone or kidney-related issues. It can also drop during infections, dehydration, or excessive sweating. Getting your blood tests reviewed and adjusting fluids or medicines usually helps control it.

A PTH level of 110.4 is very high and requires an urgent endocrinologist consultation. Treatment may include specific medicines or surgery, depending on the cause. Your breathing problems should also be checked, so do not start any medicine on your own.

Tolvat 15 (tolvaptan) and Tegrital (carbamazepine) can interact, as carbamazepine may reduce the effect of tolvaptan. Consult your doctor before taking Tolvat 15 to ensure it's safe and to adjust doses if needed. Monitoring of liver function and sodium levels may also be required.
