An Oakton physician, David Allingham, has been ordered to forfeit a $168,000 money judgment and two properties, in addition to paying $169,244 in restitution to three victims. This action follows his sentencing to 13 years in prison for improper prescribing practices involving opioids and amphetamines.
Court documents show that Allingham, 65, operated the Oakton Primary Care Center (OPCC), promoting himself as an “Addiction Medicine Family Doctor” with expertise in treating addiction. From April 2019 through January 2024, he wrote prescriptions for controlled substances without proper patient assessments. These actions were outside standard medical practice and did not meet regulatory or legitimate medical requirements.
Allingham renewed opioid prescriptions without physical examinations and instructed employees to direct patients to independent pharmacies—referred to as “mom and pop” pharmacies—to avoid detection while continuing high-dose opioid prescriptions. He also prescribed amphetamines for weight loss to chronic pain patients regardless of obesity status, contrary to regulations.
Several of Allingham’s patients died from drug overdoses shortly after receiving oxycodone prescriptions from him. In 2024, the Drug Enforcement Administration (DEA) issued an Immediate Order to Show Cause (ISO), which led Allingham to surrender his DEA registration number and lose his authority over controlled substances.
Erik S. Siebert, U.S. Attorney for the Eastern District of Virginia; Christopher C. Goumenis of the DEA Washington Division; Maureen R. Dixon of the U.S. Department of Health and Human Services Office of Inspector General; and Col. Matthew D. Hanley of Virginia State Police announced these outcomes following judgment by U.S. District Judge Rossie D. Alston Jr.
“The Fairfax County Police Department provided valuable assistance in the investigation.”
The case was prosecuted by Assistant U.S. Attorneys Heather D. Call and Annie Zanobini.
