After LAI oral dosing week 1, what is recommended for week 2?

• A. Remain at 0.5 mg BID
• B. Increase to 1 mg BID or 2 mg daily
• C. Increase to 2 mg BID or 4 mg daily
• D. Switch to 25 mg weekly

Answer: (B)

Initiation of a long-acting injectable antipsychotic often uses a cautious, stepwise oral overlap to build up therapeutic levels while monitoring tolerability. Starting with a very low oral dose minimizes early side effects as the LAI begins to release the drug. In the next week, increasing to about 1 mg twice daily, or 2 mg per day, provides a more substantial, yet still moderate, exposure to achieve better symptom control as the LAI continues to reach steady state. This gradual uptitration helps balance efficacy with tolerability and avoids both underdosing and abrupt high exposure. Jumping to a much higher weekly dose or staying at the initial low dose would either risk insufficient control or unnecessary side effects during this early period.
