  Weight gain was not common

  At 6 months, the average weight change for people on CAPLYTA was -0.02 lbs.

  CAPLYTA may cause weight gain. You and your healthcare provider should monitor your weight.

  Movement disorders, including inner feelings of restlessness or the need to move around (akathisia) were not common when taking CAPLYTA.
