Overview
Sedilix-Dm Linctus combines dextromethorphan (a cough suppressant), promethazine (a sedating antihistamine), and pseudoephedrine (a decongestant) in a single oral linctus used for the symptomatic relief of dry, irritating cough associated with the common cold, flu, or upper respiratory tract infection, along with nasal congestion.
Dextromethorphan acts on the cough centre in the brain to raise the threshold for triggering a cough. Promethazine blocks histamine receptors, helping to reduce cough reflex sensitivity and calm irritation, while pseudoephedrine narrows blood vessels in the nasal passages to relieve congestion.
How it Works
Dextromethorphan acts centrally on the cough centre in the medulla of the brain, raising the threshold required to trigger a cough. Promethazine blocks histamine H1 receptors, which contributes to reducing throat and airway irritation and has a sedating effect. Pseudoephedrine stimulates alpha-adrenergic receptors in the nasal blood vessels, causing them to constrict and relieving nasal and sinus congestion.
Directions for Use
Measure the dose accurately using the measuring cup or spoon provided. Taking the last dose of the day closer to bedtime may help, since promethazine’s sedating effect can cause drowsiness. Avoid alcohol while taking this medicine, as it can increase drowsiness.
Dosage
The dose depends on age and should follow the measuring device provided and your doctor’s or pharmacist’s advice, not exceeding the maximum recommended daily dose or duration of use. Avoid using together with other cough, cold, or allergy products containing similar ingredients.
Shelf Life
