What is the daily dose on day 8 if needed in the titration schedule?

• A. 1 mg
• B. 2 mg
• C. 3 mg
• D. 4 mg

Answer: (D)

In a titration schedule, you start at a low dose and increase in predefined steps to balance efficacy with tolerability. Here, the dose is increased in two-day intervals: the first two days use a small dose, then it steps up to the next level for the following two days, and so on. By the time you reach the final escalation window, the daily dose is the highest step in the plan.

On day eight, if escalation is still needed, the protocol assigns the highest step—4 mg. So this is the dose you would use on day eight if the patient still requires more exposure. The earlier, smaller doses (1 mg, 2 mg, 3 mg) correspond to earlier days or earlier steps, not day eight. The “if needed” qualifier means you only move to 4 mg if the patient hasn’t achieved the desired response or tolerability with the lower doses.
