(CNN) Brian Tarantina -- who recently played Jackie in Amazon's "The Marvelous Mrs. Maisel" -- died of "acute intoxication by the combined effects of fentanyl, heroin, diazepam and cocaine," the New York City Medical Examiner's office said.

The 60-year-old actor's death was accidental, according to the medical examiner's office.

He was found in his midtown Manhattan apartment in early November after someone called 911 and said he was unconscious. Medics pronounced him dead at the scene, the New York Police Department previously told CNN.

Tarantina had been "quite ill recently" and was recuperating at home, his manager previously told CNN.

"He was an amazing, very, very talented actor and very sweet person," Laurie Smith said. "I was really shocked and very sad. I'm still shocked."
