This medication is to be taken as a dissolving tablet in the mouth, but it is not absorbed through the oral mucosa; it must be swallowed with saliva or water.

The efficacy of this medication may be reduced when taken with some antifungal drugs or certain anticancer agents, so be sure to inform about other medications being taken. Elderly patients may require dosage adjustment or frequency modification due to decreased kidney function leading to increased medication concentration.
