Yes. You can be charged with a DUI even if you took medication prescribed by a doctor when an officer believes that your driving was impaired as a result. The presence of a legally prescribed medication does not automatically prevent criminal charges if the state can show that your ability to operate a vehicle was compromised. The prosecution typically relies on officer observations, field tests, and chemical testing to support allegations of impairment. It is important to provide medical documentation that shows lawful use and dosage information to explain the context of medication use. Lawful prescription use can be a central part of a defense, but it must be shown that medication did not impair your driving at the time of the incident. Collecting prescription records, physician notes, and pharmacy receipts early helps demonstrate legitimate use and timing. These records may support arguments that the medication was taken as directed and that symptoms observed by officers are consistent with lawful medical conditions rather than impairment.
