During use, serious side effects may occur, including allergic reactions, blood abnormalities, skin rashes, liver function abnormalities, muscle pain, cardiac rhythm disturbances, altered consciousness, and renal function problems, so symptoms should be monitored carefully. If any of these unusual symptoms appear, discontinue use immediately and consult a physician.

This medication dissolves in the mouth but is not absorbed in the oral cavity, so it is recommended to swallow it with water or saliva. Patients receiving hemodialysis should be cautious, as the effectiveness may decrease when taking this medication with phosphate binders. It may interact with other medications, so especially when taking antifungal agents or some chemotherapy drugs, consult with a physician. Elderly patients may experience increased drug concentration due to decreased renal function, so dosage adjustment may be necessary. Women who are pregnant or may become pregnant should only take this medication if the benefit outweighs the risk, and breastfeeding mothers are advised to discontinue breastfeeding while using this medication. There is not enough safety data for children, so caution is required when using it in this population.
