An Introduction to Clarinex-D Side Effects
As with any medicine, there are possible side effects with
Clarinex-D® (
desloratadine and pseudoephedrine); but not everyone who takes
Clarinex-D will have side effects. In fact, most people tolerate the drug 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 Clarinex-D 12 Hour
® and 3.4 percent of people stopped taking Clarinex-D 24 Hour
® because of side effects.
(This article covers many, but not all, of the possible side effects with Clarinex-D. Your healthcare provider can discuss a more complete list of Clarinex-D side effects with you.)
