Patient’s Leaflet

What is it and how is it used?

Samsca, which contains the active substance tolvaptan, belongs to a group of medicines called vasopressin antagonists. This means that it prevents vasopressin having its effect on water retention. This leads to a reduction in the amount of water in the body by increasing urine production and as a result it increases the level of sodium in your blood.

You have been prescribed Samsca because you have a disease called ?syndrome of inappropriate antidiuretic hormone secretion? (SIADH). This disease causes an inappropriate production of the hormone vasopressin which has caused the sodium levels in your blood to get too low (hyponatraemia). That can lead to difficulties in concentration and memory, or in keeping your balance.

What do you have to consider before using it?

Do not take Samsca
  • if you are allergic to tolvaptan or any of the other ingredients of Samsca (see section 6)
  • if your kidneys do not work (no urine production)
  • if you have a condition which increases the salt in your blood (?hypernatraemia?)
  • if you have a condition which is associated with a very low blood volume
  • if you do not realise when you are thirsty
  • if you are pregnant
  • if you are breastfeeding.
Take special care with Samsca

Before taking Samsca tell your doctor:

  • if you cannot drink enough water or if you are fluid restricted
  • if you have difficulties in urination or have an enlarged prostate
  • if you suffer from liver disease
  • if you have diabetes.

Drinking enough water
Samsca causes water loss because it increases your urine production. This water loss may result in side effects such as dry mouth and thirst (see section 4). It is therefore important that you have access to water and that you are able to drink sufficient amounts when you feel thirsty.

Children
Samsca is not suitable for children and adolescents (under age 18).

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Products containing ketoconazole (against fungal infections), macrolide antibiotics, or diltiazem (treatment for high blood pressure and chest pain) may increase the effects of Samsca. Samsca may increase the effect of digoxin (used for treatment of irregularities of heart beat and heart failure). Barbiturates (used to treat epilepsy/seizures and some sleep disorders) or rifampicin (against tuberculosis) may decrease the effects of Samsca.

It may still be alright for you to take these medicines and Samsca together. Your doctor will be able to decide what is suitable for you.

  • Avoid drinking grapefruit juice when taking Samsca.
