This drug should not be used in patients with a history of hypersensitivity to its components. It should also not be administered to patients with a history of acute porphyria, as it may induce acute porphyric attacks. Patients with impaired renal function should use this drug with caution, as it may accumulate in the body; dosage reduction or prolonged dosing intervals may be necessary. Patients with impaired liver function should also use it cautiously. Patients with a history of allergic reactions to medications, elderly patients, and those taking non-steroidal anti-inflammatory drugs should be monitored closely. This drug may mask symptoms of gastric cancer, therefore patients with gastric ulcers or those over middle age with newly occurring dyspeptic symptoms must confirm that it is not a malignant condition before administration. Patients with positive Helicobacter pylori for gastric or duodenal ulcers require eradication therapy. Rarely, allergic reactions or shock symptoms may occur during this medication; if any abnormal symptoms occur, administration should be stopped immediately and medical staff should be consulted. Routine monitoring of blood, liver, and kidney functions is required. Dizziness or drowsiness may occur, so patients should avoid driving or operating dangerous machinery when these symptoms are present. Potential interactions with other medications may occur, so patients should inform the medical staff of any concomitant medications. Pregnant or nursing women should only take this medication when the benefit of treatment outweighs the risks, as its safety has not been established. Safety in children has not been adequately verified, hence caution is required. Elderly patients may require dosage adjustment due to prolonged retention of the drug in the body from renal function decline. Although special intoxication symptoms are rare in cases of overdose, appropriate treatment such as vomiting or gastric lavage may be necessary. This medication should be kept out of the reach of children, and transferring to other containers should be avoided.
