Can Prescription Medication Lead to a DWI

There are many misconceptions surrounding a charge of driving while intoxicated. One of the common mistakes many people make when thinking about DWI is that only someone under the influence of alcohol can be arrested. Any driver that is under the influence of any substance that impairs their ability to drive a car may be arrested for DWI, even if that substance is prescription medication.

While prescription medication is prescribed by a doctor to help you treat a symptom, these drugs are still considered controlled substances, meaning that they have a limited scope of use. They are listed as controlled substances usually because they affect the normal function of your body in some way. If you are taking prescription drugs and driving a vehicle, you may be charged with DWI.

For an alcohol-related DWI, law enforcement can use your blood alcohol content (BAC) to prove that you were intoxicated. Unfortunately, there is no way to measure the amount of drugs that must be in a driver’s bloodstream before they are considered to be too impaired to drive. Therefore, police must prove that your mental or physical abilities were impaired by taking the prescription medication.

If you have been lawfully arrested and are under the influence of medication, you may be facing:

First DWI

  • 180 days in jail
  • $2,000 fine

Second DWI

  • One year in jail
  • $4,000 fine

Third DWI

  • 10 years in prison
  • $10,000 fine

In addition, a judge may decide to order you to:

  • Install an ignition interlock device on your vehicle
  • Serve community service
  • Attend DWI school
  • Suspend your license
  • Ensure you have a criminal record

Arrested for DUI with Drugs?

When many people think of what it makes to get a DWI, they think of someone that has gone to the bar, consumed a lot of alcohol, and then got behind the wheel of their vehicle extremely intoxicated. This is definitely one component of driving while intoxicated, but under Texas law, it is illegal for anyone to be under the influence of any substance when driving. Not only does this include alcohol, but also legal and illegal controlled substances. Therefore, someone driving after taking any substance can find themselves facing a criminal charge for DWI.

There are some crucial elements that must be present in order to make a DWI arrest. First, the person that has been accused of driving intoxicated must have been in physical control of the car and while they were under control on the car, were also impaired by some substance in order to be unable to drive similarly to someone that is sober. These substances include illegal controlled substances and legal prescription medications.


Proving that someone has been impaired by drugs can be difficult. For one, unlike alcohol, there is no solid bottom line that needs to be surpassed to be considered impaired. Drugs can have a significantly different impact on each person that consumes them, meaning that someone may not be impaired on these substances.

Additional defenses include:

  • Officer lacked a valid reason to make a traffic stop to begin with
  • Chemical tests used to test for drugs were not properly administered
  • A controlled substance was consumed without the driver’s consent
  • Officer did not follow the proper procedure when making the stop

Depending on the details of your case, any number of additional defenses may apply, which will be important based on the penalties you may be facing as a result. For a first DWI with drug offense in Texas, the sentencing you may be facing includes between 72 hours and 180 days in jail, a $2,000 fine, installation of an ignition interlock device, community service, drug treatment programs, license suspension, and more. If more than one DWI arrest exists on your record, you may be facing additional penalties.
