Expectorant vs. Decongestant: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on December 31, 2023
An expectorant helps clear mucus from the respiratory tract, while a decongestant reduces swelling in nasal passages to ease breathing.

Key Differences

Expectorants are designed to thin and loosen mucus in the chest and throat, facilitating easier coughing up of mucus. Decongestants, in contrast, work by narrowing blood vessels in the nasal passages, reducing swelling and congestion.
