Avoid Blowing Your Nose & Find Congestion Relief With ZYRTEC-D

What Is a Decongestant?

A decongestant works to relieve the nasal and sinus congestion that makes breathing difficult. Decongestants come in various forms, including pills, liquid, nasal sprays and drops.

Although often confused, decongestants are different from antihistamines. Antihistamines help relieve most allergy symptoms by blocking the action of histamine in your system, not the congestion.

ZYRTEC-D® contains both an antihistamine and a decongestant for allergies. It powerfully clears your blocked nose and relieves other allergy symptoms. You can find decongestant products like ZYRTEC-D® at your local drug store behind the pharmacy counter. No prescription is necessary.

How Do Decongestants Work for Allergies?

Allergens can irritate your nasal passages, causing them to swell and create fluid. This swelling can lead to a stuffy nose and sinus pressure.

What does a decongestant do? It provides temporary relief by cutting down on the fluid in the lining of your nose to relieve swollen nasal passages and congestion. Take a decongestant when you suffer from sinus congestion, sinus pressure and other typical allergy symptoms.
