Oakton doctor admits guilt in illegal prescription operation

Jessica D. Aber, U.S. Attorney | U.S. Attorney for the Eastern District of Virginia

An Oakton doctor, David Allingham, has admitted guilt to charges of conspiracy to distribute oxycodone and amphetamines, maintaining drug premises, and making false statements related to healthcare matters. The 64-year-old owned and operated the Oakton Primacy Care Center (OPCC), where he prescribed opioids and amphetamines without proper patient assessments between April 2019 and January 2024.

Court documents reveal that Virginia pharmacies filled about 7,330 prescriptions for oxycodone from Allingham, totaling around 405,164 pills. Patients were required to pay $300-$550 for office visits out-of-pocket. An additional $700 was needed for a doctor's letter. Office visits were often conducted over the phone by non-medically trained employees.

Pharmacies began refusing to fill prescriptions from Allingham due to concerns about his prescribing practices. In response, he instructed staff to favor smaller pharmacies over national chains. On at least 487 occasions, untrained staff issued prescriptions in his absence, generating at least $168,000.

Urine drug screens were typically required but not appropriately acted upon by Allingham. Despite failed tests being ignored or falsely documented, prescriptions continued. One patient who failed multiple tests was still prescribed oxycodone.

Allingham also prescribed amphetamines for weight loss against regulations regardless of obesity status. At least 527 such prescriptions were distributed during this period.

Additionally, Allingham unlawfully used another doctor's identity to prescribe medications for himself and his family without authorization.

The investigation revealed that several patients died from overdoses shortly after receiving prescriptions from Allingham. Law enforcement searched his residence and practice in July 2023; during interviews, he made false statements about his practices.

Allingham faces up to 20 years in prison with sentencing scheduled for April 30. Actual sentences are usually less than maximum penalties under federal guidelines.

Jessica D. Aber of the U.S Attorney's Office announced the plea acceptance along with DEA's Jarod Forget, Maureen R. Dixon from Health and Human Services' Office of Inspector General, and Virginia State Police Superintendent Colonel Gary T. Settle after it was accepted by U.S District Judge Rossie D Alston Jr.

The Fairfax County Police Department assisted significantly in the investigation led by Assistant U.S Attorney Heather D Call prosecuting the case.
