​Prescription Drugs

The Unfair Discrimination in Drug Pricing statute (Wis. Stat. § 100.31) requires that wholesalers treat all purchasers (persons who engage primarily in selling drugs directly to consumers) with all the rights and privileges offered or accorded the most favored purchaser​, including purchase prices for similar volume purchases, rebates, free merchandise, samples, and similar trade concessions.

Penalties for violations of the Unfair Discrimination in Drug Pricing include:

  • Civil forfeitures of not less than $100 nor more than $10,000 for each offense.
  • Any purchaser damaged by violations may sue for treble damages.

Penalties for violating any of the three listed regulations may include agency-issued special orders and court-​issued injunctions. In addition, any person suffering pecuniary losses because of a violation of a previously issued agency order or injunction may sue for double damages.​
