Charlie Sheen has been taken to hospital for psychiatric checks after police were called to his New York hotel room.
A police source said a woman in his room told officers the 45-year-old was highly intoxicated and had been screaming and throwing furniture.
The Two And A Half Men star was not arrested, but checked himself into a hospital for an evaluation.
His publicist said the 45-year-old was expected to be released tomorrow (Wednesday). "What we are able to determine is that Charlie had an adverse allergic reaction to some medication and was taken to the hospital," he said.
Charlie was in New York with ex-wife Denise Richards, 39, and their two daughters, although the identity of the woman who was with him is unclear.
Denise is in the Big Apple to promote her series Blue Mountain State, the Daily Mail reports.
In August, Charlie pleaded guilty to third-degree assault after a Christmas Day assault on his wife, Brooke Mueller Sheen. Prosecutors dropped more serious charges and he avoided jail time and he was sentenced to 30 days in a rehabilitation centre, 30 days of probation and 36 hours of anger management.
Sheen's publicist Stan Rosenfield said the 45-year-old was expected to be released on Wednesday.
"Charlie had an adverse allergic reaction to some medication and was taken to the hospital," he said.
Police haven't received any complaints from the hotel about any possible damage. A message left with the historic hotel at the foot of Central Park wasn't returned.
