Mucolytic and expectorant effects in acute and chronic respiratory diseases
This medicine helps to loosen and expel mucus in acute and chronic respiratory diseases, facilitating the elimination of phlegm through expectoration. It is used to alleviate discomfort and improve symptoms due to respiratory diseases.
Adults: Administer 300 mg of erdosteine per dose orally, 2~3 times daily. When administered for acute respiratory disease, do not administer continuously for more than 10 days.
This medication should not be used in the following patients: First, individuals with allergic reactions to this medication or its ingredients should not take it. Second, patients with liver cirrhosis and those with cystathionine synthase deficiency should avoid this medication as its metabolites may interfere with the metabolism of specific amino acids in the body. Third, patients with ulcers in the stomach or duodenum should not take this medication. Fourth, patients with severely impaired kidney function, specifically those with a creatinine clearance of less than 25 mL/min, should not use this medication. Fifth, patients with significantly reduced liver function should also avoid taking this medication. Additionally, caution should be exercised in the following cases: First, patients with mild to moderate liver dysfunction should limit the dosage of this medication to no more than 300 mg per day and take it carefully. Second, diabetic patients or those on a low-calorie diet need to be particularly careful when using syrup formulations. In the case of overdose, symptoms such as excessive sweating, dizziness, and facial flushing may occur. Common side effects may include headache, cold symptoms, difficulty breathing, altered taste, nausea, vomiting, diarrhea, abdominal pain, and heartburn. Skin reactions like urticaria, rash, or eczema may also occur. When taking this medication, combining it with expectorants can lessen the cough while making it difficult to expel phlegm from the bronchi, raising the risk of bronchial infection and potentially causing bronchospasm, so care should be taken. Pregnant or breastfeeding women should avoid using this medication due to uncertainties regarding its safety. Finally, this medication should be stored out of reach of children, and transferring it to another container should be done cautiously to prevent accidents or deterioration of quality.
