Which product uses 25-50 mg q 2 weeks?

• A. Risperidone RBP-7000
• B. Risperidone Consta
• C. Aripiprazole Maintena
• D. Paliperidone palmitate 1-monthly

Answer: (B)

The main idea here is recognizing the dosing schedule of long-acting injectable antipsychotics. Risperidone Consta is the risperidone long-acting injectable given every two weeks, with a dose range of about 25 mg to 50 mg per injection depending on response and tolerability. That biweekly 25-50 mg pattern directly matches the question.

Aripiprazole Maintena and paliperidone palmitate (the 1-monthly form) are both monthly injections, not every two weeks, so they don’t fit the schedule. Risperidone RBP-7000 is another long-acting risperidone product, but its approved dosing schedule isn’t defined by the 25-50 mg every two weeks in the same way, so it doesn’t align with the given interval and range.
