This medication should not be used in patients with allergies or hypersensitivity to this drug or its components. Patients with liver cirrhosis or cystathionine synthase deficiency should not be administered this medication as its metabolites may interfere with methionine metabolism. It is also safer to avoid use in patients with peptic ulcers or severe renal or hepatic dysfunction. In patients with mild to moderate hepatic impairment, it should be used cautiously, and the dosage should not exceed 300 mg per day. Diabetic patients or those on a low-calorie diet should be particularly cautious when using the syrup formulation of this medication. This medication contains a dye called Yellow No. 5; hence, patients with allergies or a history of hypersensitivity to this component should be administered with caution. Taking excessive amounts may cause symptoms such as sweating, dizziness, and flushing, so it is crucial to adhere to the prescribed dosage. Side effects such as headaches, cold symptoms, dyspnea, taste disturbances, nausea, vomiting, diarrhea, abdominal pain, and heartburn may occur; consult your doctor if you experience any unusual symptoms. Be aware of skin reactions like hives, erythema, and eczema. Caution is advised when taking this medication with other cough medicines, as it may complicate phlegm expulsion and increase the risk of bronchial infections.
