An Introduction to Clarinex Side Effects
As with any medicine, there are possible side effects with
Clarinex® (
desloratadine); but not everyone who takes Clarinex will have side effects. In fact, most people tolerate Clarinex well. When people do develop Clarinex side effects, in most cases, they are minor, meaning that they require no treatment or are easily treated by you or your healthcare provider. In previous research studies, up to 2.4 percent of people stopped taking Clarinex because of side effects.
