Prince was treated for a drug overdose 6 days before his death … multiple sources tell TMZ.

We broke the story … Prince’s private jet made an emergency landing in Moline, Illinois last Friday, hours after he performed in Atlanta. At the time his reps said he was battling the flu … something we questioned because his plane was only 48 minutes from home before the unscheduled landing.

Multiple sources in Moline tell us, Prince was rushed to a hospital and doctors gave him a “save shot” … typically administered to counteract the effects of an opiate.
