Which antipsychotic is listed as a postpartum psychosis treatment option?

• A. Clozapine
• B. Asenapine
• C. Lurasidone
• D. Haloperidol

Answer: (B)

Postpartum psychosis requires rapid stabilization with an antipsychotic that is effective, well tolerated, and has a reasonable safety profile for a breastfeeding mother and her infant. Asenapine fits these needs in the context of some guidelines and resources that list it as a postpartum psychosis treatment option because it can quickly control acute psychotic symptoms and mania, while often having a favorable tolerability profile compared with some other second-generation antipsychotics. It also has a sublingual form that can be convenient in the immediate postpartum period when swallowing pills might be challenging and provides reliable absorption.

Clozapine is typically reserved for treatment-resistant cases due to the risk of agranulocytosis and other serious side effects, so it is not a first-line postpartum option. Lurasidone has strong efficacy for mood disorders with psychotic features but has less established data for breastfeeding safety and postpartum use. Haloperidol is a classic choice with well-established efficacy and rapid onset, but it carries higher risk of extrapyramidal symptoms and prolactin elevation, which can be less desirable for a lactating mother.
