Lastuss LA Syrup contains Dextromethorphan Hydrobromide 15mg/5ml, a centrally acting antitussive agent used to relieve dry, non-productive cough. Dextromethorphan acts on the cough center in the medulla oblongata to suppress the cough reflex without causing respiratory depression or addiction. This medication is indicated for symptomatic relief of cough associated with upper respiratory tract infections, bronchitis, and other conditions where cough is persistent and irritating. Lastuss LA Syrup is suitable for adults and children above the recommended age, with dosage adjusted according to age and severity of symptoms. It is important to use the syrup as directed, avoiding excessive doses to prevent potential side effects such as dizziness, nausea, or gastrointestinal discomfort. Caution is advised in patients with a history of hypersensitivity to dextromethorphan or any of the syrup’s excipients. The syrup should not be used concomitantly with monoamine oxidase inhibitors (MAOIs) or within 14 days of their discontinuation due to the risk of serotonin syndrome. Pregnant and lactating women should consult a healthcare professional before use. Lastuss LA Syrup provides effective cough suppression, improving patient comfort and facilitating rest during illness.
