Desloratadine and Pseudoephedrine Side Effects: An Introduction
As with any medicine, side effects are possible with
desloratadine and pseudoephedrine (
Clarinex-D®); but not everyone who takes the drug will have side effects. In fact, most people tolerate it quite well. When people do develop side effects, in most cases, they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider. In previous research studies, up to 3.6 percent of people stopped taking the 12-hour dose of
desloratadine and
pseudoephedrine and 3.4 percent of people stopped taking the 24-hour dose because of side effects.
(This article covers many, but not all, of the possible side effects with desloratadine and pseudoephedrine. Your healthcare provider can discuss a more complete list of desloratadine and pseudoephedrine side effects with you.)
