Cough Syrup Secrets: Expert Debunks Myths
4 Dec
Summary
- Cough medicines soothe throats but don't treat viruses.
- Cheaper supermarket brands are as effective as name brands.
- Dextromethorphan's cough suppression impact is minimal.

Colds typically necessitate a natural recovery process, with most coughs originating from these common viruses. Cough medicines primarily offer symptomatic relief by soothing throat irritation rather than addressing the root viral cause. Professor Jacky Smith, a respiratory medicine expert, clarifies that many active ingredients, such as dextromethorphan, provide only a minimal effect on suppressing the cough reflex.
Consumers can find effective relief without overspending, as Professor Smith points out that budget-friendly supermarket own-brands are just as potent as premium versions. However, she cautions that many syrup-based remedies contain very high sugar levels. For those concerned about sugar intake, sugar-free formulations are available and recommended.
Ingredients like levomenthol can offer a cooling sensation, masking throat irritation and limiting the urge to cough. While dosage is crucial for all medications, it is particularly important for dextromethorphan due to its potential for addiction, reinforcing the need to adhere strictly to label instructions.
