How does this medication work? What will it do for me?
This medication contains 2 active ingredients, loratadine and pseudoephedrine. Together, loratadine and pseudoephedrine work to relieve the symptoms associated with allergic rhinitis, including nasal and sinus congestion, sneezing, postnasal discharge, and tearing and redness of the eyes.
During an allergic reaction, the body produces a chemical called histamine, which causes allergy symptoms such as hives, runny nose, congestion, and itchy, watery eyes. Loratadine belongs to a group of medications known as antihistamines. It works by blocking the action of histamine in the body.
Pseudoephedrine belongs to a group of medications called decongestants. It works by narrowing the blood vessels. This helps to clear and prevent the symptoms of congestion.
