Final Thoughts

You may experience some or none of the Zyrtec-D side effects listed in this article. 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 the drug. Also, let your healthcare provider know if you develop something that "just does not seem right." While the issue may not be due to a side effect, your healthcare provider will be able to diagnose and treat the problem.
