This medication should not be used by patients who have had allergic reactions to specific components or similar drugs. It contains lactose, so patients with a deficiency in lactose-degrading enzymes or genetic conditions that prevent lactose digestion should not take this medication. Patients with a history of drug allergies, decreased kidney function, heart diseases, poor liver function, and elderly patients should use this medication with caution. Serious allergic reactions, blood cell reductions, severe damage to the skin and mucous membranes, hepatic dysfunction, muscle damage, cardiac rhythm problems, consciousness disorders, renal inflammation, and lung inflammation could occur, so careful observation is required. If these symptoms appear, immediately discontinue the medication and seek medical treatment. The tablet dissolves in the mouth but is not absorbed in the mouth, so it should be swallowed with a sufficient amount of saliva or water. It is important to regularly undergo blood tests and liver and kidney function tests, while carefully monitoring treatment progress. Patients receiving blood dialysis should be cautious when using this medication with certain phosphate binders, as the efficacy of the binders may decrease. The medication may lose effectiveness when used with some antifungal agents or chemotherapeutics, so consult a doctor or pharmacist. Elderly individuals may have reduced kidney function, which could increase drug concentration, therefore care should be taken to reduce dosage or extend administration intervals. Women who are pregnant or may become pregnant should only use this medication when the benefits outweigh the risks, and safety has not been fully confirmed. Nursing mothers should discontinue breastfeeding as this medication may be passed into breast milk. The safety of this medication has not been sufficiently confirmed for children, so use with caution. In particular, the oral disintegrating tablet form of this medication should be placed on the tongue and dissolved with saliva before ingestion, and should not be taken while lying down without water. Finally, taking this medication may mask symptoms of gastric cancer, so it should only be used when it is certain that it is not gastric cancer.
