3 common myths about DWI and prescription medications

On Behalf of The Shapiro Law Firm | Oct 26, 2025 | DWI-DUI

Driving under the influence is not always about alcohol. Prescription medications can affect coordination, judgment and reaction time. They can also lead to a DWI charge in Texas. Many drivers assume prescription drugs are always safe while driving. Understanding these 3 common myths can help you make informed decisions and protect yourself from serious legal trouble.

Myth 1: If a doctor prescribes it, it is legal to drive


Some people think taking medication that is prescribed protects them from a DWI charge. Texas law focuses on impairment, and even prescribed medications can slow reflexes or reduce alertness. If an officer notices unsafe driving, you could still face a DWI charge.

Myth 2: Only illegal drugs can lead to a DWI

Many drivers believe that only substances like marijuana, cocaine or methamphetamine result in a DWI. In Texas, any drug that affects your ability to drive, including prescription or over-the-counter medications, can lead to charges. Officers focus on how you drive, not just whether a substance is legal.

Myth 3: Following dosage instructions keeps you safe from DWI charges


Taking medication as prescribed does not always guarantee safe driving. Side effects, tolerance or interactions with other medications can still impair your ability to operate a vehicle. Mixing prescription drugs with alcohol increases the risk of impairment and legal consequences.

Even when following instructions carefully, medications can unpredictably affect driving. Being aware of these myths helps you make safer choices and understand your responsibilities on the road.

Protecting yourself and your rights

 

Driving safely is about more than avoiding legal trouble. It protects you and others on the road. If you are charged with a DWI while taking prescription medications, consult an experienced attorney. A lawyer can guide you step by step through the legal process. Knowing the laws and your rights can make a real difference in the outcome of your case.
