Olanzapine is a prescription atypical antipsychotic medication primarily used to balance dopamine and serotonin levels in the brain. Treatment regimens and specific tablet strengths are individualized and may be adjusted by a doctor depending on how well the medication works and how it is tolerated.

Common Side Effects
Olanzapine is highly effective, but it is known for several physical and metabolic side effects:
-
Metabolic Changes: Significant weight gain, increased appetite, and elevated blood sugar or cholesterol levels.
-
Neurological Symptoms: Sleepiness, dizziness, lack of energy, and minor tremors.
-
Physical Discomfort: Dry mouth and constipation.

Crucial Safety Precautions
-
Dementia Warning: Olanzapine carries a strict boxed warning indicating it must not be used to treat behavioral problems in older adults with dementia-related psychosis, as it increases the risk of stroke and death.
-
Alcohol & Interactions: It should not be taken with alcohol, sleep aids, or benzodiazepines (like diazepam or lorazepam), as the combination can cause dangerous drowsiness or severe blood pressure drops.
-
Proper Discontinuation: Never stop taking this medication abruptly. Sudden discontinuation can cause severe withdrawal or a return of psychiatric symptoms. A doctor will provide a structured, gradual tapering schedule if you need to stop.
