When looking for the treatment of respiratory problems like colds, coughs, infections, or any sort of allergies and looking for medications, expectorant and decongestants are some common terms.
What is most important for the patient to understand while taking these medications is that they do not cure any underlying illness, but they do help in relieving the symptoms and reduce the inflammation caused by the illness in the respiratory system.
Key Takeaways
- Expectorants help thin and loosen mucus in the respiratory tract, making it easier to cough up.
- Decongestants constrict blood vessels in the nasal passages, reducing swelling and congestion.
- Expectorants are used for productive coughs, while decongestants are used for nasal and sinus congestion.
Expectorant vs Decongestant
The difference between expectorant and decongestant is the part of the respiratory system they treat particularly. Decongestant is given when there is swelling in the nasal passage, gives relief to a stuffy nose, headache due to sinus, or difficulty in hearing due to excess phlegm. Decongestant makes that phlegm run faster to make it easier to spit or expel from the system.
Expectorants can be natural ingredients, too, basically any ingredient that helps clear the mucus from the airway and doesn’t let breathing obstruct.
Decongestants are medicines used for treating problems with the respiratory system. They are used while facing the problem of a stuffy or blocked nose.
