This medication should not be used in patients with hypersensitivity to the ingredients or other H2 receptor antagonists. It contains lactose, so it should not be taken by patients with genetic disorders such as galactose intolerance, Lapp lactase deficiency, and glucose-galactose malabsorption. Caution should be exercised while using this medication in patients with hypersensitivity to the drug, and those with kidney, heart, or liver problems, as well as in the elderly. Especially in patients with decreased kidney function, drug concentration in the blood may increase, necessitating a reduction in dosage or adjustment of dosing intervals. This medication can cause cardiovascular side effects in patients with heart conditions, so caution is essential. During use, serious side effects like allergic reactions, severe skin rashes, blood disorders, liver function abnormalities, myalgia, heart rhythm abnormalities, or consciousness disturbances may occur. If any abnormal symptoms appear, the medication should be stopped immediately, and medical attention should be sought. Mild side effects such as indigestion, headache, drowsiness, dizziness, and skin rashes may occur, and if these persist, consulting a healthcare professional is advisable. This medication dissolves in the mouth but is not absorbed through the oral mucosa, hence it must be swallowed with water. Patients receiving blood dialysis should be cautious, as taking this medication alongside phosphate binders may reduce its effectiveness. Moreover, when taken with certain antifungals or specific anticancer medications, the concentration of the drug may be affected, leading to decreased efficacy, so patients must inform their doctor or pharmacist before taking. Elderly patients may require dosage adjustments as the drug can remain in their body longer due to decreased kidney function. Women who are pregnant or may become pregnant should carefully consider the risks and benefits before taking this medication. If breastfeeding, it is advisable to discontinue nursing as the drug may pass into breast milk. Safety for children has not been adequately determined; therefore, special caution is needed when administering to children. Finally, this medication can mask symptoms of gastric cancer, so it is safer to confirm the absence of malignant diseases before using.
