"As a preventative measure, Charlie Sheen has entered a rehabilitation facility," his rep says in a statement. "He will take some time off his series Two and a Half Men."
Sheen, 44, is also facing domestic violence charges stemming from a Christmas Day fight with wife Brooke Mueller, who herself went into rehab earlier this month, then switched centers amid complaints that her privacy was breached.
The statement did not elaborate on the reason for Sheen's treatment. The actor has reportedly gone to rehab programs at least twice before for drug and alcohol abuse, but a source says that this time the problem relates to the emotional fallout from the domestic violence case and his desire to avoid temptation. A relapse would be a violation of his bail terms and could send him back to jail.
"Charlie is stressed. He's tired. The kids are on his mind. Brooke's on his mind," the source tells PEOPLE. "A lot of things are on his mind. He didn't want to get a place where he had the urge to get high. He's not using and he doesn't want to. He felt like he needed to get away from negative influences around him and clear his head, rest and take a short break."
The source adds that Sheen's twin boys would be staying with his parents, actor Martin Sheen and wife Janet, and with Mueller at her rehab facility. Mueller's mother also planned to travel to California from Florida to help.
Production of Sheen's show "will be temporarily suspended," says a statement from CBS and the show's producer, Warner Bros. Television. "We wish him nothing but the best as he deals with this personal matter."
