Betaloc Zok Dose Adjustment

Impaired Renal Function
The elimination rate is insignificantly affected by renal function, and dose adjustment is therefore not needed in impaired renal function.

Impaired Hepatic Function
Usually Betaloc ZOK is given in the same dose to patients suffering from liver cirrhosis as to patients with normal liver function. Only when there are signs of very severe impairment of liver function (e.g. shunt operated patients), a dose reduction should be considered.

Elderly
Dose adjustment is not needed

Children
There is limited experience with Betaloc ZOK treatment in children.
