When taking this medication, it dissolves in the mouth but is not absorbed through the mucous membranes, so it must be swallowed with water or saliva. Patients undergoing dialysis should take care when using this medication in combination with certain phosphate binders, as this may reduce the effectiveness of the medication. Also, this medication may reduce the effectiveness of certain antifungal agents or anticancer drugs when taken together, so patients should inform their doctor or pharmacist if they are taking other medications. Elderly patients may have reduced kidney function, leading to increased blood concentration of this medication, so the dose should be reduced or the interval between doses increased, and caution should be exercised.

Breastfeeding women are recommended to discontinue breastfeeding, as this medication may be transmitted through breast milk.
