This medication should not be used by patients with allergies to its components or similar drugs. Additionally, this drug contains lactose, hence it should not be administered to patients with genetic conditions that prevent lactose digestion. Patients with a history of drug allergies or impaired kidney function should use this drug with caution, and dosage should be reduced or the dosing interval extended as necessary. Patients with heart disease may experience cardiac side effects when using this drug; hence careful monitoring is advised. Patients with impaired liver function should also be cautious as symptoms may worsen during treatment. Elderly patients are likely to have reduced kidney function, which can lead to increased blood drug concentrations; thus, dosage adjustment is required. This medication can rarely cause serious allergic reactions, hematological disorders, skin conditions, liver dysfunction, muscle damage, arrhythmias, altered consciousness, kidney damage, lung disease, among other side effects, so any unusual symptoms should prompt immediate consultation with a physician. Generally, treatment should be conducted while monitoring effectiveness at the minimal effective dose, and if no effect is observed, a change in treatment should be considered. This drug dissolves in the mouth but is not absorbed through the oral mucosa, so it must be swallowed with water or saliva. Patients undergoing hemodialysis should be cautious when taking this drug with certain phosphate binders as calcium absorption may decrease. This medication may interfere with the absorption of some antifungal agents, so consultation with a physician is necessary when taken concurrently. Women who are pregnant or may become pregnant should use this medication only when the benefits outweigh the risks, and breastfeeding women should discontinue breastfeeding as the drug can be transmitted through breast milk. The safety in children has not been sufficiently established, so use in pediatric patients should be approached with caution. Finally, this drug can mask symptoms of gastric cancer, so it should be used only after confirming that a malignant tumor is not present.
