Oz struck a deal with iHeartMedia that will begin later this year, according to a release this week from Oz and the Texas-based company.
It will involve more projects than "The Daily Dose," but further details were not immediately available, Oz spokesman Tim Sullivan said Friday.
The minute-long "The Daily Dose" will air on its current radio syndicator, Westwood One, through the end of May.
The show was produced by the former Harpo Radio, which was part of Oprah Winfrey's Harpo Productions. When Harpo Radio closed last December, it and Westwood One mutually agreed to end their relationship, Harpo said.
The changes allowed Oz to consider new offers, Sullivan said.
In a letter Wednesday to affiliates noting the final "Daily Dose" feature will be sent May 29, Westwood One offered a replacement, "A Better Life with Dr. Sanjay Gupta," the CNN chief medical correspondent.
The switch comes amid controversy for Oz, whose "The Dr. Oz Show" is co-produced by Sony Pictures Television and Harpo Productions. The physician was accused by a group of 10 fellow doctors of promoting "quack treatments" on the daytime TV program.
In response, Oz contended the attack was spurred by his support for labeling genetically modified foods.
