Renalog/Renalog DS Drug Interactions

Simultaneous administration of medicinal products that contain calcium (e.g. acetolyte) may trigger, or worsen, a pathological increase in the serum calcium level. As the uremic symptoms improve under therapy with formulation/tablets, the dose of aluminum hydroxide administered should be reduced, as appropriate. The patient should be monitored for reduced levels of serum phosphate. In order not to interfere with absorption, an appropriate interval should be observed between administration of formulation/tablets and medicinal products which form poorly soluble compounds with calcium (e.g. tetracylines, quinolones such as ciprofloxacin and norfloxacin, preparations that contains iron, fluoride and estramustin). An interval of at least 2 hours should be observed between the intake of formulation/tablets and such preparations. If administration of formulation/tablets leads to increased blood levels of calcium, the sensitivity to medicinal products which increase heart action (cardiac glycosides) and thus also the risk of cardiac arrhythmia is increased.
