Clozapine Oral Suspension Side Effects

In clinical trials, some of the most commonly reported side effects of clozapine oral suspension included constipation, weight gain, and sedation. Most reactions to this drug are minor and don't require medical attention. However, notify your healthcare provider immediately if you develop any serious problems, such as uncontrollable body movements, chest pain, or an infection of any kind.


An Introduction to Side Effects of Clozapine Oral Suspension

Just like any medicine, clozapine oral suspension (Versacloz™) can cause side effects. However, not everyone who takes the medication will have severe problems. In fact, most people tolerate it reasonably well. If reactions 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 clozapine oral suspension. Your healthcare provider can discuss a more complete list with you.)
