How long does somnolance from zyprexa olanzapine last?

Somnolence, or drowsiness, from Zyprexa (olanzapine) can vary in duration depending on the individual and the dosage taken. Generally, this side effect may last for several hours after taking the medication, often peaking within the first few hours. However, some individuals may experience lingering drowsiness into the next day, especially if they take the medication at night or in higher doses. It's important to discuss any persistent side effects with a healthcare provider.
