Rocker Ozzy Osbourne filed a complaint with the state medical board, accusing a Beverly Hills doctor of overprescribing addictive drugs to him. Osbourne says the drugs led to his disoriented behavior on the reality TV series "The Osbournes," the Los Angeles Times reported.
Authorities asked Dr. David Kipper to turn over copies of Osbourne's medical records and scheduled a meeting with the British singer and his wife, Sharon.
Osbourne filed the complaint in early March, claiming Kipper had him take excessive quantities of Dexedrine, Valium, Zyprexa and other powerful medications.
Kipper's attorney, John D. Harwell, said the doctor is "always pleased to cooperate with the medical board." He declined to comment further.
Osbourne hired Kipper in June 2002 to kick a prescription drug habit. Kipper charged the Osbourne family $650,000 for his services, records show.
Osbourne and his family became international stars following the success of MTV's "The Osbournes," which shows an oft-dazed Ozzy doting over his dysfunctional family with wife-manager, Sharon.
Ozzy Osbourne has been candid about his decades of battles with substance abuse.
On Friday, Ozzy, 55, and Sharon Osbourne, 51, said in a televised interview that their 19-year-old daughter Kelly had checked into a drug rehabilitation center for an addiction to painkillers.
Kelly Osbourne's younger brother, Jack, 18, checked himself into a drug and alcohol rehabilitation clinic last year.
