"Kevin Spacey is taking the time necessary to seek evaluation and treatment. No other information is available at this time," his representative said in a statement to Variety.
The news comes less than a week after actor Anthony Rapp accused Spacey of making an unwanted sexual advance at him when he was 14-years-old.
Mexican actor Roberto Cavazos and American documentary filmmaker Tony Montana have also come forward with accounts of how Spacey allegedly made unwanted advances towards them.
Production on the sixth and last season of Netflix's "House of Cards," in which Spacey plays the lead role of Frank Underwood, has since been suspended.
MasterClass has also pulled the Oscar winner's USD 90 online class on acting from its service.
Hit TV drama "This Is Us" has removed a reference to Spacey from one of its episodes following the allegations.
