Intuniv Antitrust Litigation Settlement

If you purchased brand or generic Intuniv directly from a manufacturer between October 19, 2012 and June 1, 2015, you could get a payment from a proposed class action settlement.

The information on this webpage is only a summary. You may download a full copy of the settlement notice by clicking here.

There is a proposed settlement relating to a class action lawsuit brought by direct purchasers of brand and generic Intuniv (guanfacine). The lawsuit asserts that Shire plc, Shire LLC, and Shire U.S., Inc. (“Shire”) and Actavis Elizabeth LLC, Actavis LLC, and Actavis Holdco US, Inc. (“Actavis”) violated antitrust laws relating to the sale of these prescription pharmaceuticals. Shire and Actavis have denied any wrongdoing.

The Court has preliminarily approved the proposed settlement between the direct purchaser class and Shire, the remaining defendant. The settlement will provide for the payment of $58 million in cash into an escrow account for allocation to the members of the class after payment from the settlement fund of any court-approved attorneys’ fees and expenses to attorneys for the Class and incentive awards to the class representatives. The full text of the proposed settlement, which is dated June 18, 2024, is available for your review on the “Court Documents” section of this website.

The direct purchaser class’s claims against Actavis were resolved by an earlier settlement, which the court approved on December 9, 2020. The deadline to submit claims for the Actavis settlement has passed, and the settlement fund has been fully distributed.

For the full text of the proposed settlement agreement with Shire, along with other documents filed with the court in this case, please visit the “Court Documents” section of this website.
