Get emergency medical help if you have signs of an allergic reaction to Caplyta: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
High doses or long-term use of lumateperone can cause a serious movement disorder that may not be reversible. The longer you use Caplyta, the more likely you are to develop this disorder, especially if you are a woman or an older adult.
Call your doctor at once if you have:
feeling unsteady, feeling like you might pass out;
uncontrolled muscle movements in your face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement);
tightness in your neck or throat, trouble swallowing;
trouble breathing or speaking;
a seizure;
high blood sugar - increased thirst, increased urination, dry mouth, fruity breath odor;
low white blood cell counts - fever, chills, mouth sores, skin sores, sore throat, cough, trouble breathing; or
severe nervous system reaction - very stiff (rigid) muscles, high fever, sweating, confusion, fast or uneven heartbeats, tremors, feeling like you might pass out.
Common Caplyta side effects may include:
weight gain;
drowsiness; or
dry mouth.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
