Lange, who is a regular on Howard Stern's radio show, was taken to an unnamed medical facility on Saturday (02Jan09) but has refused to disclose any details about his condition.
A representative for Lange tells TMZ.com, "I can confirm that Artie is in the hospital. Artie has chosen to keep all information on this matter between him and his doctor. There will be no further comment."
The funnyman had his driving licence revoked for seven months in September (09) after pleading guilty to driving under the influence of drugs. He told police he had a prescribed sleeping pill in his system when he was pulled over, and was ordered to serve 12 hours in an intoxicated driver resource program.
