3.1 Weight Gain

One of the most commonly reported side effects of Zyprexa is weight gain. Studies have shown that individuals taking Zyprexa may experience an increase in appetite, leading to weight gain.

Zyprexa may cause sedation and drowsiness, particularly during the initial stages of treatment.
