Side Effects of Desloratadine
Most people do not experience side effects with desloratadine -- if they do occur, they are typically minor. Common side effects include sore throat, muscle pain, and fatigue. Rare side effects include serious allergic reaction and heart palpitations. While taking the drug, let your healthcare provider know about any possible desloratadine side effects you experience or if something just doesn't seem "right."
Side Effects of Desloratadine: An IntroductionAs with any medicine, there are possible side effects with desloratadine (Clarinex®); but not everyone who takes the drug will have side effects. In fact, most people tolerate the drug 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 2.4 percent of people stopped taking desloratadine because of side effects.
(This article covers many, but not all, of the possible side effects with desloratadine. Your healthcare provider can discuss a more complete list of desloratadine side effects with you.)
