5 Conservation of Tolvaptan Tevagen

1. Contents of the pack and other information

1. What is Tolvaptan Tevagen and what is it used for

This medicine, which contains the active substance tolvaptan, belongs to a group of medicines called vasopressin antagonists. Vasopressin is a hormone that helps prevent water loss from the body by reducing urine production. An antagonist prevents vasopressin from having its effect on water retention, which leads to a reduction in the amount of water in the body by increasing urine production and results in an increase in blood sodium levels.

Tolvaptan is used to treat low sodium levels in adults. You have been prescribed this medicine because you have low sodium levels in your blood due to a disease called "syndrome of inappropriate antidiuretic hormone secretion (SIADH)", in which the kidneys retain too much water. This disease leads to inadequate production of the vasopressin hormone, which has caused your blood sodium levels to drop too low (hyponatremia). This can cause concentration and memory difficulties or difficulty maintaining balance.

2. What you need to know before you take Tolvaptan Tevagen

Do not take Tolvaptan Tevagen:

• if you are allergic to tolvaptan or any of the other ingredients of this medicine (listed in section 6) or if you are allergic to benzazepine or benzazepine derivatives (e.g. benazepril, conivaptan, fenoldopam mesylate or mirtazapine)
• if your kidneys do not work (there is no urine production)
• if you have any disease that increases salt levels in the blood ("hypernatremia")
• if you have any disease related to very low blood volume
• if you do not feel thirsty
• if you are pregnant
• if you are breast-feeding

Warnings and precautions

Consult your doctor or pharmacist before starting to take tolvaptan:

• if you cannot drink enough water or if you have fluid restriction
• if you have difficulty urinating or have an enlarged prostate
• if you have liver disease
• if you have suffered in the past from any allergic reaction to benzacepine, tolvaptan or other benzazepine derivatives (e.g. benazepril, conivaptan, fenoldopam mesylate or mirtazapine), or to any of the other ingredients of this medicine (listed in section 6)
• if you have a kidney disease called autosomal dominant polycystic kidney disease (ADPKD)
• if you have diabetes.

Adequate water intake

Tolvaptan causes water loss because it increases urine production. This water loss can cause side effects such as dry mouth and thirst, and even more serious side effects such as kidney problems (see section 4). Therefore, it is essential that you have access to water and can drink sufficient amounts when you feel thirsty.

Children and adolescents

Tolvaptan should not be used in the treatment of children and adolescents (under 18 years of age).
