Orap Side Effects

Your healthcare provider needs to know right away if you develop serious problems like seizures, confusion, or difficulty breathing while taking Orap. Although not everyone who takes this medication experiences problems, some of the commonly reported side effects of Orap include drowsiness, vision problems, and abnormal behaviors. Seek medical attention if you develop anything that "just does not seem right."

An Introduction to Orap Side Effects

Just like any medicine, Orap® (pimozide) can cause side effects. However, not everyone who takes the drug will have problems. 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 are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Orap. Your healthcare provider can discuss a more complete list with you.)
