Acetylcysteine
About Acetylcysteine
Acetylcysteine belongs to a class of drugs called 'mucolytic agents' (cough/sputum thinner) primarily used to treat respiratory diseases associated with excessive mucus. Acute respiratory diseases are initially associated with dry, irritating cough, hoarseness in laryngitis (swelling of the voice box), or burning sensation in the chest due to bronchitis (swelling of the lining of bronchial tubes). Then, wet mucus forms, and continuous coughing out of sputum occurs. In chronic respiratory diseases, both dry irritating cough and wet cough with mucus occur.
Acetylcysteine contains 'Acetylcysteine' that works by thinning and loosening phlegm (mucus) in the lungs, windpipe, and nasal passage. Thereby, making it easier to cough out phlegm.
Take Acetylcysteine as prescribed. Your doctor will advise you on how often you take Acetylcysteine based on your medical condition. Some people may experience nausea, vomiting, stomach upset, or fever. Most of these side effects of Acetylcysteine do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.
If you are allergic to Acetylcysteine or any other medicines, please tell your doctor. Acetylcysteine is not recommended for children below 14 years of age. Drink plenty of fluids to thin mucus and lubricate your throat while taking Acetylcysteine. When the bottle is opened, the liquid (syrup) colour may change and have a bad odor. This is normal, and it does not indicate that medicine has changed. Severe skin reactions such as Stevens-Johnson syndrome (a serious and rare disorder of skin and mucus membranes) or toxic epidermal necrolysis (skin blistering or skin peeling) have been rarely reported in some patients. However, if you notice any skin rash worsening with mucosal lesions or blisters, stop taking Acetylcysteine and contact your doctor immediately. If you are pregnant or breastfeeding, please inform your doctor before taking Acetylcysteine. If you have a history of stomach ulcers or have asthma inform your doctor before taking Acetylcysteine.
