Indications for use:
KETOSTERIL is indicated for the prevention and treatment of the consequences of abnormal or inadequate protein metabolism in adult patients with chronic kidney disease, in combination with limited protein intake in the diet of 40 g/day or less.

Caution should be exercised when taking the medicine in patients with phenylketonuria (see section: KETOSTERIL contains phenylalanine). During treatment with KETOSTERIL, your doctor may order regular monitoring of blood calcium levels.

- antibiotics (used to treat infections, such as tetracyclines, quinolones, such as ciprofloxacin and norfloxacin);
- medicines containing iron, fluorine;
- estramustine (a medicine used to treat prostate cancer). Be cautious when taking KETOSTERIL with:
- medicines containing calcium - which may cause or exacerbate elevated blood calcium levels.
- cardiac glycosides (medicines used to treat heart failure and arrhythmias) - KETOSTERIL may cause elevated blood calcium levels, which increases the sensitivity to cardiac glycosides. Therefore, they should be used with caution due to the risk of heart rhythm disorders.
