What are the most common side effects of ZYPREXA?
A5: Every medicine offers healing benefits for many individuals along with the possibility of undesired effects. At Lilly, we believe our most important job is to protect patient safety, which means being completely up front about potential side effects. Like all medicines, ZYPREXA can cause side effects. Medications affect people in different ways. Some common side effects of ZYPREXA are sleepiness, lack of energy, changes in behavior, dizziness, tremors (shakes), dry mouth, restlessness, and having hard or infrequent stools. These side effects generally do not bother people enough to cause them to stop taking ZYPREXA. This is not a complete list of side effects. You can find more information in the Important Safety Information and in the Medication Guide or by consulting the Prescribing Information on this site. Talk to your doctor about any questions or concerns.
