Which antipsychotic must be taken with food for efficacy?

Meal-dependent absorption is the key idea here. Ziprasidone must be taken with food because its oral bioavailability rises dramatically when a meal is consumed. Without food, the drug is poorly absorbed, so plasma levels may stay subtherapeutic and the medication may not work as well. When taken with a meal—typically around 500 calories or more—the absorption improves enough to reach effective concentrations, allowing the drug to work as intended. The other antipsychotics listed do not require food for efficacy; their absorption isn’t significantly affected by meals, so they can be taken with or without food without impacting how well they work.
