Can You Be Charged with a DUI for Prescription Drugs in Virginia?

 Posted on April 18, 2026 in Drug DUI

Most people think of a DUI as something that happens when someone drives after drinking. If not that, they think it’s driving after having smoked marijuana or some other drug. What surprises many drivers is that you can be charged with a DUI in Virginia for taking a legally prescribed medication. If you were pulled over and charged after taking a drug your doctor gave you, a Leesburg, VA DUI defense lawyer can help you understand what options you have in 2026.

When Does a Prescription Medication Still Qualify as a DUI in Virginia?

Virginia law covers more than just alcohol or illegal drugs in its DUI laws. Virginia Code § 18.2-266 states that it's illegal to drive while under the influence of any drug that impairs your ability to operate a vehicle safely. That includes controlled substances, over-the-counter medications, and sometimes prescription drugs that your doctor prescribed to you.

Not every prescription drug impairs driving. Basic fever-reducers are unlikely to be a problem. However, medications that cause drowsiness, like nighttime medications or anti-nausea meds, are risky.

Common Medications That Can Get You Charged with a DUI in Virginia

Many common medications can affect driving ability in ways that law enforcement may treat as impairment. Some of the most frequently involved drug categories include:

• Opioid pain relievers such as oxycodone, hydrocodone, and codeine

• Benzodiazepines prescribed for anxiety and/or sleep

• Muscle relaxants like Flexeril or Soma

• Stimulants, including Adderall and Ritalin, when taken in excess

• Antihistamines and allergy medications that cause drowsiness

• Sleep aids such as Ambien or Lunesta

Even a medication you've taken for years without incident can cause impairment under the right conditions. This could be because your dosage changed, you combined it with another drug, or you didn't eat enough.

How Do Police Officers Prove Prescription Drug Impairment in a DUI Case?

Unlike a breathalyzer for alcohol, no roadside test measures prescription drug impairment. When an officer suspects drug impairment during a traffic stop, they may call in a Drug Recognition Evaluator, or DRE. A DRE is an officer who has completed specialized training to identify signs of drug impairment. This is done with a series of physical and observational tests. These include checking your pupil size, pulse, blood pressure, muscle tone, and coordination.

If the DRE concludes you may be impaired, police can request a blood test. Blood results can show the presence of a drug in your system, but not necessarily if the dose was high enough to make you "impaired."

Because there's no set number for impairment, the way there is for blood alcohol content, prescription DUI cases often come down to interpretation. That gives an experienced defense attorney more room to challenge the evidence.

Challenging Evidence of a Prescription Medicine DUI

Every case is unique, but some common ways an experienced attorney could challenge the evidence against you in this type of DUI case include questioning the following:

• Whether the DRE's evaluation was conducted correctly and followed proper protocol

• Whether the blood draw was done lawfully and the sample was handled correctly

• Whether the drug levels in your system actually correlate with impairment

• Whether there were other explanations for the officer's observations, such as fatigue, a medical condition, or nervousness during the stop

Having someone who knows how to leverage these angles can be a game-changer in many cases.

What Are the Consequences of Prescription Drug DUI in Virginia?

The penalties for a DUI in Virginia do not change just because the substance involved was prescribed. A first-offense DUI is a Class 1 misdemeanor, which carries up to 12 months in jail, a fine of up to $2,500, and a mandatory license suspension of one year. A second or subsequent offense has mandatory jail time and longer suspensions.

A DUI conviction also goes on your record. This can affect your employment, your insurance rates, and, depending on your situation, your immigration status. If you're not a U.S. citizen, a DUI conviction can have serious consequences that go beyond the criminal penalties. This is especially a circumstance where having a defense attorney who understands DUI law can make a difference.
