Products Description&Tips
Pharmacist Selection Guide
For daytime dry cough: Start with dextromethorphan short-acting for effective, non-sedating relief.
​For all-day dry cough: Use Dylsem as it is long-acting that provides up to 12-hour cough relief.
For nighttime cough: Night formulas with doxylamine can help suppress coughing and promote sleep. Avoid daytime use due to drowsiness.
For children: Use only age-appropriate syrups, honey products (not for children under 1 year), or throat soothers. Adult formulas are not safe for kids.
For extra comfort: Chest rubs are a helpful add-on for nighttime relief.
Stay hydrated: Hydration with warm fluids such as warm soup, or milk with honey could help soothe the throat, and humidifying the repiratory passages.
​Important:
Avoid cough suppressants if heavy mucus or phlegm is present, as they can make chest congestion harder to clear.
Use caution with sedating products if driving or operating heavy machinery.
