Lumateperone
Generic: lumateperone tosylate · Brand: Caplyta® · Class: 2nd Gen Antipsychotic / Serotonin-Dopamine Modulator
🧠
How It Works
Lumateperone is a newer second-generation antipsychotic with a uniquely selective and multi-modal mechanism. It simultaneously modulates serotonin, dopamine, and glutamate pathways — but at much lower dopamine D2 receptor occupancy than traditional antipsychotics. This low D2 occupancy is thought to explain its favorable tolerability profile: minimal movement side effects, minimal weight gain, minimal sedation, and minimal metabolic effects. It is FDA-approved for schizophrenia and bipolar depression (both as monotherapy and adjunct), and is one of the best-tolerated antipsychotics currently available.

Tips for Success
Same Time DailyTake at the same time each day for consistent levels in your system.
With FoodTaking with food reduces nausea and stomach upset.

Important Safety Information
Tardive Dyskinesia: Long-term use can cause involuntary repetitive movements of the face, tongue, or limbs. Report any unusual movements to your provider immediately.
Elderly Patients with Dementia: Antipsychotics carry a black box warning for increased risk of death in elderly patients with dementia-related psychosis. Not approved for this use.
Metabolic Effects: Many antipsychotics can cause weight gain, elevated blood sugar, and increased cholesterol. Your provider will monitor these regularly.
Pregnancy & Breastfeeding: Discuss risks and benefits with your provider. Do not stop without consultation.
Drug Interactions: Antipsychotics interact with many medications. Always share your full medication list.
CYP3A4 Interactions: Lumateperone is sensitive to CYP3A4 inhibitors (like ketoconazole, clarithromycin) and inducers (like rifampin, carbamazepine). These can significantly raise or lower lumateperone levels. Always share your full medication list.
