“Ray Donovan” star Liev Schreiber is on the mend after being hospitalized in New York City on Nov. 16.

Schreiber, 58, sought medical attention on Sunday after suffering a “massive headache” and remained in the hospital overnight to undergo further testing, TMZ reported.

“Out of an abundance of caution, Liev went into the hospital for testing, and as of [Monday] afternoon, he has been cleared to return to work,” the actor’s representative told The Epoch Times via email on Tuesday.

No additional information was provided about Schreiber’s condition or the cause of his headache. However, the actor previously experienced a similar health scare.

During an April 2024 appearance on “Late Night with Seth Meyers,” Schreiber recounted how a severe headache caused him to suffer temporary amnesia while performing in a Broadway production of “Doubt: A Parable”—a revival of playwright John Patrick Shanley’s award-winning play.

“I do the first six or seven lines of the play, sort of automatically, and I realize I’m not connected, so I decide, let me try to get connected again. And the minute I do that, it all vanishes. The play is gone from my head,” he recalled. “My doctor shows up—who’s a friend—and he has a terrified expression. My wife shows up—she looks terrified. I think, ‘Okay, I’ve had a stroke.’”

Schreiber subsequently underwent an MRI, which revealed his brain was “perfectly fine” and had no bleeding.

A neurologist ultimately informed the actor that he had experienced an episode of transient global amnesia brought on by his severe headache.

“The [doctor] said, ‘You’ll never have this again and it’ll be gone in 8 to 24 hours,’ which I didn’t believe,” he continued. “I go to sleep, I wake up, I remember the whole play ... and I never had another problem with it.”

According to the Mayo Clinic, transient global amnesia occurs suddenly, causing a temporary lapse in short-term memory. The condition most commonly affects those who are middle-aged or older and typically subsides after a few hours.

Schreiber, known for his roles in “The Manchurian Candidate” (2004) and “X-Men Origins: Wolverine” (2009), recently starred alongside Austin Butler and Zoë Kravitz in the Darren Aronofsky-directed comedic caper “Caught Stealing,” which premiered in August.

This summer, he also began filming a new thriller series for Apple TV+ based on the internationally bestselling “Joona Linna” crime novels by Lars Kepler—the pseudonym of husband-and-wife Swedish authors Alexander Ahndoril and Alexandra Coelho Ahndoril. An official release date for the 10-episode drama has not yet been announced.
