Based on experience with the use of other medicinal products that affect the renin-angiotensin system, concomitant use of potassium-sparing diuretics, potassium supplements, salt substitutes containing potassium or other medicinal products that may increase serum potassium levels (e. g. heparin) may lead to increases in serum potassium and is, therefore, not recommended (see section 4.4).
