Identifying Cough Types
Coughs are generally divided into two main categories, and choosing the wrong medication can hinder recovery:
- Dry Cough: Non-productive, ticklish coughs caused by irritation. These are treated with cough suppressants (antitussives).
- Wet, Chest Cough: Productive coughs that help clear phlegm and mucus. These are treated with expectorants.
How Delsym 12 Hour Works
Delsym contains Dextromethorphan Polistirex, an extended-release cough suppressant that targets the cough reflex in the brain, providing dry cough relief that lasts up to 12 hours.
Clinical Guidelines
Expectorants (like Guaifenesin) should be taken with plenty of water to help thin out mucus. Suppressants should be avoided if you have a productive wet cough, as coughing is necessary to clear lungs.
