1. What is KETOSTERIL and what is it used for

KETOSTERIL is a medicinal product used in nutritional therapy for patients with kidney function disorders (renal insufficiency).

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. It is usually used in patients with a glomerular filtration rate (first stage of urine formation) of less than 25 ml/min.

2. Important information before taking KETOSTERIL

When not to take KETOSTERIL

Do not take the medicine:

  • if you are allergic to the active substances or any of the other ingredients of this medicine (listed in section 6);
  • if you have elevated blood calcium levels (hypercalcemia);
  • if you have amino acid metabolism disorders (disorders of protein metabolism in the body).

Warnings and precautions

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. When taking KETOSTERIL with aluminum hydroxide, monitor phosphate levels (see section: KETOSTERIL and other medicines). During treatment, you should consume sufficient calories, which is necessary to maintain good health.

Children

There is no sufficient data on the use of KETOSTERIL in children.

KETOSTERIL and other medicines

Tell your doctor or pharmacist about all medicines you are taking, or have recently taken, and about any medicines you plan to take. To avoid absorption disorders, keep at least 2 hoursintervalbetween taking KETOSTERIL and any of the following medicines that form poorly soluble compounds with calcium:

  • 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.
  • aluminum hydroxide - during treatment with KETOSTERIL, the symptoms of uremia decrease, so when taking aluminum hydroxide, your doctor may reduce the dose of KETOSTERIL and order phosphate level monitoring.

KETOSTERIL with food and drink

The medicine should be taken during meals.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. The decision to use KETOSTERIL in pregnant and breastfeeding women will be made by your doctor.

Driving and using machines

KETOSTERIL has no effect on the ability to drive and use machines.

KETOSTERIL contains phenylalanine

The medicine may be harmful to patients with phenylketonuria (a hereditary disorder of metabolism).
