Marilyn Manson needed hospital treatment in Los Angeles during the recording of his new album.
The singer says on his official website he went too far following a "strenuous week".
His new The Golden Age Of Grotesque LP will be released in the autumn.
Manson said: "This week was strenuous and I landed myself in the hospital as a result of going too far in the creation process.
"I am fine now and glad to be back in the studio. We have just completed the last track for the album and it is my favourite so far."
