Los Angeles - Dan Ackroyd was rushed to hospital on Saturday.
The Ghostbusters actor called 911 complaining of abdominal pains and was taken from his home to a Santa Monica hospital by paramedics.
Sources told TMZ the 63-year-old star was suffering from a minor stomach ailment and underwent tests but doctors have yet to determine the cause of the pain.
He has now been released and is recovering at home.
Dan recently opened up about his memories of working on Ghostbusters in 1981 and admitted walking the streets of New York with his co-stars Bill Murray, Harold Ramis and Ernie Hudson made him feel like he "owned" the city.
Speaking about the iconic scene where the ghoul-fighting gang of scientists defeat the giant Stay Puft Marshmallow Man who attacks New York City - he said: "The biggest joy was taking over New York, just watching the people in the city react when we were driving about in the Ecto-1 and walking about with the packs, coming out of public places... There we were, the four of us, Harold, Ernie and me and Billy going to work.
"It was a great time. I owned Chicago once, with The Blues Brothers, and on the Ghostbusters I owned New York."
The actor is currently producing the female led reboot which is currently under production and stars Melissa McCarthy, Kristen Wiig, Kate McKinnon, and Leslie Jones as the ghost busting gang, with Chris Hemsworth as their side-kick secretary.
