As with any medicine, side effects are possible with Zyrtec. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.

It is also approved to treat itching due to hives, which may or may not be caused by allergies. The medication is also available in combination with a decongestant (see Zyrtec-D for more information). Although Zyrtec and Zyrtec-D were originally prescription products, they are now available without a prescription.
