Understanding Dextromethorphan

Dextromethorphan is a widely used over-the-counter (OTC) medication primarily designed to alleviate dry coughs. It is available in both capsule and liquid suspension forms, making it convenient for users.

The most recognized brand names include Delsym and Robitussin Long-Acting CoughGels. Generally, generic medications are proven to be as safe and effective as their brand-name counterparts while usually being more cost-effective.
