Rare Side EffectsDuring clinical studies, a number of other side effects occurred in less than 2 percent of people while they were taking Clarinex. It is difficult to tell whether these side effects occurred because of Clarinex or something else.
Some of these rare Clarinex side effects include but are not limited to:
- Serious allergic reaction
- Rapid heart rate (tachycardia)
- Heart palpitations
- Increased liver enzymes.
It is possible that you may experience some or none of these Clarinex side effects. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried.
Therefore, make sure to let your healthcare provider know if you develop any side effects while taking this product. Also, let your healthcare provider know if you develop something that "just does not seem right." While it may not be a side effect, your healthcare provider will be able to diagnose and treat the problem.
