Matthew Perry 's doctors won't be able to prescribe medication anymore. Salvador Plasencia and Mark Chavez —two of the five people charged in connection to the Friends alum's death—have surrendered their registrations to write prescriptions, the U.S.

Drug Enforcement Administration (DEA) confirmed to E! News Aug. 19. E! News reached out to Chavez's and Plasencia's attorneys for comment but has not heard back.

Perry was found dead in the hot tub at his California home on Oct. 28. In December, the actor's death was ruled a drug and drowning-related accident —the result of the "acute effects of ketamine"—by the Los Angeles Medical Examiner.

In an Aug. 15 press conference, the Department of Justice revealed that Plasencia and Chavez were among five people who have been accused of "profiting off" Perry's longtime struggle with drug addiction and charged for their alleged involvement his passing. Prosecutors also named Plasencia one of the lead defendants, alleging that the doctor worked with the Fools Rush In star's assistant Kenneth Iwamasa to distribute approximately 20 vials of ketamine to him between September and October 2023 in exchange for $55,000 cash.

(Iwamasa pleaded guilty on Aug. 7 to one count of conspiracy to distribute ketamine causing death.) And that's not the only accusation the DOJ made against the medical professionals.

Placensia also allegedly exchanged text messages with Chavez ——a San Diego-based physician who is accused of selling ketamine to Pl.
