Which statement about rizatriptan in pediatric use is accurate?

• A. Rizatriptan has pediatric approval with fixed dosing.
• B. Rizatriptan has pediatric approval with weight-based dosing.
• C. Rizatriptan is not approved for pediatric use.
• D. Rizatriptan dosing is unrelated to weight.

Answer: (B)

In pediatric patients, drug dosing for rizatriptan is based on body weight to achieve similar exposure and minimize side effects. The approved pediatric regimen uses weight-based dosing, typically about 5 mg for children weighing approximately 20–40 kg and 10 mg for those over 40 kg, rather than a single fixed dose for all kids. This reflects how children of different sizes metabolize drugs differently, so a one-size-fits-all dose doesn’t reliably produce the desired effect. Rizatriptan is approved for acute migraine treatment in children, usually ages 6 to 17, with dosing guided by weight. Therefore, the statement that rizatriptan has pediatric approval with weight-based dosing is accurate. Fixed dosing would not be appropriate for pediatrics, and it is not correct to say there is no pediatric approval or that weight does not influence dosing.
