Lots of people get nasal congestion due to allergies. However, antihistamines don't help with this particular allergy symptom (since congestion isn't caused by histamine). In order to treat congestion, it is necessary to add a nasal decongestant (such as pseudoephedrine). Claritin comes in a combination product that contains pseudoephedrine (Claritin-D), just for this purpose.
The second major ingredient in Claritin, Claritin D and other allergy ingredients is pseudoephedrine. Pseudoephedrine acts as a decongestant, clearing up stuffy or runny noses. Many cough, cold and allergy preparations contain this drug.
