Prescription medication plays an important role in daily life, from managing pain to helping with chronic conditions. But even when a doctor prescribes it, the law in Oregon takes driving under the influence very seriously. At The Donahue Law Firm, our team has worked with people in Bend and throughout Central Oregon who never thought their prescription could lead to criminal charges.

Oregon’s DUI Laws Cover More Than Alcohol

Most people think of DUI as an alcohol-related charge, but Oregon law applies to any substance that can impair driving. This includes prescription drugs like opioids, muscle relaxants, anti-anxiety medications, and even sleep aids. If the police suspect impairment, a prescription will not act as a free pass.

Medications That Can Trigger DUI Charges

Certain medications affect reaction time, focus, and coordination. Painkillers, sedatives, and strong antihistamines are well-known for causing drowsiness or slowed reflexes. Even when taken as prescribed, these effects can put a driver at risk of being pulled over and charged.

How Police Detect Impairment from Prescriptions

Unlike alcohol, prescription drug impairment cannot be measured with a breathalyzer. Instead, officers rely on field sobriety tests, observations, and sometimes drug recognition experts. Blood or urine tests may also be used, but they only confirm the presence of a drug, not whether it was impairing at the time.

Potential Penalties for DUI on Prescription Drugs

A DUI conviction based on prescription drugs carries the same penalties as one based on alcohol. This can include license suspension, fines, mandatory classes, and even jail time. For someone who thought they were following their doctor’s advice, the consequences can feel especially heavy.
