Which antipsychotic is taken twice daily (BID) in tablet form?

Fanapt is indeed taken twice daily in tablet form, making it the correct answer. This medication is an atypical antipsychotic used to treat schizophrenia. Its dosing schedule requires administration two times a day, which helps maintain steadier blood levels of the medication, effectively managing symptoms associated with the condition.

In contrast, Invega Sustenna is given as a long-acting injectable formulation typically administered once a month. Saphris, another antipsychotic, is taken sublingually, meaning it dissolves under the tongue, and is also not typically scheduled for twice-daily oral ingestion. Rexulti is generally taken once daily, further distinguishing it from Fanapt. Therefore, the specific twice-daily requirement for Fanapt in tablet form confirms its suitability as the answer to the question.
