Benzphetamine (Didrex) is listed under which schedule?

• A. Schedule II
• B. Schedule I
• C. Schedule IV
• D. Schedule III

Answer: (D)

Benzphetamine (Didrex) is classified under Schedule III because it has an accepted medical use as an appetite suppressant, but its potential for abuse and dependence is greater than drugs placed in Schedule IV and not as high as those in Schedule II. Scheduling weighs both medical use and abuse potential, and Didrex sits in the middle: enough risk to not be Schedule IV, but not so high as Schedule II. For comparison, other anorectics like phentermine are often Schedule IV, illustrating how similar uses can differ in scheduling based on abuse risk.
