Many people assume DUI charges only apply to drunk driving. In Florida, that is a dangerous misconception. Under Florida law, you can be charged with DUI even if you have not consumed a single drop of alcohol — and even if the substance in your system was legally prescribed by a doctor.
At The Brancato Law Firm, P.A., we have extensive experience defending clients charged with DUI involving prescription drugs. Here’s what you need to know if you are facing these serious charges.
Under Florida Statute 316.193, a person can be convicted of DUI if they are:
Driving or in actual physical control of a vehicle, and
Under the influence of alcoholic beverages, any chemical substance listed in Florida Statute 877.111, or any controlled substance under Chapter 893,
To the extent that their normal faculties are impaired.
This includes:
Prescription painkillers (Oxycodone, Hydrocodone)
Anxiety medications (Xanax, Valium)
Sleep medications (Ambien, Lunesta)
ADHD medications (Adderall, Ritalin)
Antidepressants and mood stabilizers
Even properly taken prescription drugs can lead to a DUI arrest if law enforcement believes you were impaired.
Florida law enforcement officers are trained to watch for signs of impairment from:
Opioid painkillers
Anti-anxiety medications (benzodiazepines)
Sleep aids (sedatives)
Stimulants (amphetamines)
Antihistamines or muscle relaxers that cause drowsiness
You do not have to be abusing or misusing these medications to be arrested. All it takes is an officer’s belief that your driving was impaired.
DUI investigations for prescription drugs often involve:
Observations of driving behavior (weaving, slow driving, failure to maintain lane)
Field sobriety exercises (which may not fairly account for medical conditions)
Statements made by the driver about medications
Requests for urine or blood samples to detect substances
Unlike alcohol DUIs, there is no legal limit for prescription drug DUI cases. Officers and prosecutors rely heavily on subjective observations and chemical testing.
DUI charges based on prescription drugs are often defensible. Common strategies include:
Questioning the legality of the stop: Was there reasonable suspicion to pull you over?
Challenging field sobriety tests: Were they fairly administered given your medical conditions?
Attacking urine or blood test reliability: Lab errors, chain of custody problems, or passive presence (metabolites) can create defenses.
Medical necessity defenses: Showing that therapeutic use of a medication did not impair normal faculties.
Consulting toxicology experts: To explain that presence of a substance does not prove impairment.
Prescription drug DUI cases are highly technical — and often winnable with the right defense.
The penalties for a DUI based on prescription drug impairment are the same as for alcohol DUIs:
Jail time
Fines
Probation
Driver’s license suspension
DUI school and substance abuse counseling
Ignition interlock device in some cases
A conviction also results in a permanent criminal record that can affect employment, professional licenses, insurance, and more.
Yes.
Having a lawful prescription is not a defense to DUI in Florida.
The issue is not whether the substance was legally obtained — it is whether it impaired your ability to drive safely.
Even perfectly legal and properly used medications can result in DUI charges if your normal faculties were impaired.
Prescription drug DUIs are more complicated than alcohol-based DUIs. They require:
Knowledge of toxicology and pharmacology
Experience challenging chemical evidence
Ability to cross-examine police officers and lab technicians
Familiarity with medical defenses and expert witnesses
