This drug should not be used in certain patients. It can be dangerous for patients who have a history of allergy to the ingredients contained in this drug or similar medications. Additionally, it contains lactose and should not be used in patients with a genetic disorder that impairs lactose digestion. Caution is also required for some patients when using this drug. Patients with a history of allergies, impaired kidney function, heart disease, poor liver function, and the elderly should use this medication cautiously. In particular, patients with impaired kidney function may have elevated drug concentrations, so dosages may need to be reduced or intervals between doses extended. This drug can cause several serious side effects. Rarely, symptoms such as shock or severe allergic reactions may occur, so symptoms should be closely monitored, and if any abnormalities arise, administration should be stopped immediately, and treatment should be pursued. Regular blood tests are necessary due to the risk of a decrease in blood cell counts or problems such as anemia or thrombocytopenia. There are also risks of severe skin rashes or mucosal damage, liver dysfunction, muscle damage, heart rhythm abnormalities, consciousness disturbances, seizures, nephritis, and pneumonia. If these symptoms occur, drug use should be stopped immediately, and appropriate treatment should be sought. This medication dissolves in the mouth but is not absorbed in the mouth, so it must be swallowed with water or saliva. Patients receiving blood dialysis should be cautious when using this drug in conjunction with other medications, as its effectiveness may decrease. When used with other medications, drug interactions may occur. In particular, the effectiveness of this drug or other drugs may be reduced when used with certain antifungal agents or specific anticancer drugs, so consulting a doctor or pharmacist is necessary. Elderly patients are more likely to have reduced kidney function, which may lead to elevated drug concentrations; thus, dosage adjustments may be necessary. Pregnant women or those who may become pregnant should only use this drug when the benefits of treatment outweigh the risks, and breastfeeding mothers should discontinue breastfeeding as the drug may be transmitted through breast milk. The safety of this drug in children has not been sufficiently confirmed, so it should be used cautiously in children. Lastly, this drug may mask symptoms of gastric cancer, making it important to confirm the presence of malignancy before using it.
