This medication should not be used by individuals who have had allergic reactions to its components or H2 receptor antagonists. In addition, since it contains lactose, those with lactose intolerance or specific genetic metabolic disorders should not take it. Individuals with drug hypersensitivity should use this medication with caution, and those with impaired kidney function may require dosage adjustments due to potential increased drug concentration. People with cardiovascular diseases should be cautious due to the potential for cardiovascular side effects. Individuals with impaired liver function should also take care as symptoms may worsen with the use of this medication. Furthermore, elderly patients often have reduced kidney function, potentially leading to higher drug concentrations, hence should be administered with caution. Rarely, serious side effects can include allergic reactions, blood disorders, skin diseases, liver dysfunction, muscle breakdown, cardiac rhythm disturbances, altered consciousness, nephritis, and pneumonia. If these symptoms occur, stop taking the medication immediately and consult a doctor. Common side effects may include skin rash, indigestion, blood pressure changes, headaches, drowsiness, depression, dizziness, and if these occur, you should inform your doctor. This medication should be monitored for therapeutic effects, and only the necessary minimum dosage should be used, with alternative treatments considered if there is no effectiveness. When taking, it dissolves in the mouth but is not absorbed by mucosa, therefore it must be swallowed with water. Patients undergoing dialysis should be cautious when using this medication with phosphate binders, as their effectiveness may be reduced. Taking this medication concurrently with certain antifungals or specific anticancer drugs can reduce its effectiveness, so inform your doctor or pharmacist if you are taking other medications. Women who are pregnant or may become pregnant should only use this medication after carefully assessing its benefits and risks, and those who are breastfeeding should discontinue breastfeeding during use.
