It was earlier suggested that the actor was discovered "intoxicated, irrational and emotionally disturbed" at a New York hotel, but his rep later insisted that he suffered an "adverse allergic reaction to some medication".
Sheen was in the area to visit former wife Denise Richards and their daughters Sam, 6, and Lola, 5. However, Richards, who appeared on The Joy Behar Show on Tuesday, apparently refused to withdraw the reasons for Sheen's sudden hospitalisation in order to protect their kids.
People quotes her as saying: "We're in an amazing place, we've been getting along great for the last year, year and a half. We're doing our best, so as far as that situation, I'm trying to protect the girls from it as much as possible... I did help him at the hospital.
"My daughters are 5 and 6 years old. And they're at an age when they can start to understand, they have no idea what went on and a lot of... our stuff happened when they were much younger, which I'm so grateful for."
Sheen's spokesperson later stated: "Charlie Sheen has been discharged from a hospital in NY and is returning to LA today. Everything else is speculation."
