This medication should not be used in patients with hypersensitivity to its ingredients or those who have had allergic reactions to other H2 receptor antagonists. It contains lactose, so it should not be administered to patients with genetic issues such as galactose intolerance, lactase deficiency, or glucose-galactose malabsorption. Special caution should be taken when administering this medication to patients who have hypersensitivity to drugs, renal impairment, heart disease or liver dysfunction, and elderly patients. In particular, patients with poor kidney function may experience increased drug concentration, therefore the dosage should be reduced or the dosing interval should be extended. While taking this medication, various adverse reactions may rarely occur, such as severe allergic reactions or blood-related anomalies, skin disorders, liver dysfunction, muscle damage, cardiac rhythm abnormalities, consciousness disturbances, kidney problems, pneumonia, etc., so symptoms should be closely monitored. If abnormal symptoms occur, discontinue the medication immediately and seek appropriate treatment. During treatment, the progress should be adequately monitored, using the minimum effective dose, and if there is no effect, it is advisable to switch to other treatment methods. This medication dissolves in the mouth but is not absorbed through the oral mucosa, so it must be swallowed with water or saliva. Caution should be taken when using this medication along with phosphate binders in patients undergoing hemodialysis, as it may reduce the efficacy of the phosphate binders. This medication can lower the blood concentrations of certain antifungal agents and specific anticancer agents, so watch for drug interactions. Elderly patients have a higher likelihood of renal function decline, so the dosage should be reduced or the dosing interval extended, for cautious use. Women who are pregnant or may become pregnant should use this medication only when the benefits outweigh the risks, as safety has not been firmly established. It is recommended that breastfeeding be stopped since this medication may be transmitted through breast milk. The safety in pediatric patients has not been sufficiently confirmed, so caution is needed when using this medication. Finally, this medication can mask symptoms of stomach cancer, so it should only be used after confirming that the condition is non-malignant.
