Overview

Zontron Coredin Paediatric Linctus Syrup contains diphenhydramine hydrochloride together with ammonium chloride, a combination antihistamine and expectorant cough syrup formulated for children to relieve coughs associated with colds, including dry, irritating cough and cough with mucus.

Diphenhydramine is a sedating antihistamine that also has cough-suppressant activity, while ammonium chloride acts as an expectorant that helps loosen and thin mucus, making it easier to clear from the airways; together they relieve both dry and productive cough symptoms.

How it Works

Diphenhydramine blocks histamine H1 receptors, which suppresses the cough reflex and reduces allergy-related symptoms such as sneezing and a runny nose, while ammonium chloride irritates the stomach lining in a way that reflexively increases watery secretions in the airways, helping to thin and loosen mucus so it can be cleared more easily by coughing.

Directions for Use

Shake the bottle well before use, measure the dose accurately using the provided measuring cup or spoon, and give at the intervals directed by your doctor or pharmacist. Do not use household spoons to measure the dose.

Dosage

The dose is based on the child’s age and body weight, using the measuring device provided with the syrup, and should be determined by the treating doctor or pharmacist rather than estimated – do not exceed the recommended dose or frequency.

Shelf Life

Refer to the expiry date printed on the packaging.

Storage Instructions

Store below 30°C in a dry place, away from direct sunlight and out of reach of children.

Side Effects

  • Nausea or vomiting
  • Abdominal discomfort
  • Headache
  • Fatigue or weakness
  • Irritability or confusion (with high doses)
  • Metabolic acidosis (in rare or prolonged cases)

Contraindications

  • Known hypersensitivity to diphenhydramine, ammonium chloride, or any ingredient in the syrup
  • Infants below the minimum age stated on the product label or as advised by a doctor
  • Severe liver or kidney impairment, due to the ammonium chloride component
  • Concurrent use of other sedating antihistamines or cough-and-cold products containing similar ingredients, to avoid excess dosing

Drug / Food Interactions

  • Other sedating antihistamines, cough and cold medicines, or sleep aids taken together can increase drowsiness and the risk of excess sedation.
  • Ammonium chloride can affect the elimination of certain other medicines from the body – inform your doctor of all medicines your child is taking.
  • Inform your doctor or pharmacist of all other medicines, including other over-the-counter cold remedies, before combining with this syrup.

Quick Tips

  • Always use the measuring device provided to give an accurate dose.
  • Avoid giving other cough, cold, or allergy medicines at the same time to prevent accidentally doubling up on similar ingredients.
  • Monitor your child for excessive drowsiness or unusual excitability and contact your doctor if this occurs.
  • See your doctor if cough persists beyond a week, is accompanied by high fever, or is associated with difficulty breathing.
