Many people associate DUI charges with only alcohol or illegal drugs. However, even legally prescribed medications can lead to criminal charges if they impair your ability to drive safely. If you were arrested for a DUI after taking a prescription drug, understanding your rights and Iowa’s laws is crucial. Continue reading for more information and contact a knowledgeable Dallas County OWI lawyer to discuss your situation today.

What is a DUI?

While many states use the term “DUI” (Driving Under the Influence), Iowa officially uses “OWI,” which stands for Operating While Intoxicated. The difference is subtle but important. “Operating” is a broader term under Iowa law, meaning you don’t necessarily have to be caught actively driving to face charges. If you are found in physical control of a vehicle, even if parked, and are intoxicated, you can be charged with OWI.

If your mental or physical function is impaired to the extent that your judgment is compromised and you cannot safely operate a vehicle, you are in violation of Iowa’s OWI laws and can face serious repercussions.

Can Prescription Drug Use Result in a DUI in IA?

Yes. Under Iowa Code § 321J.2, a person can be charged with an OWI if they are operating a motor vehicle while under the influence of any drug, including legally prescribed medication. The law does not distinguish between illegal substances and drugs prescribed by a doctor if the drugs impair the driver.

The determining factor is not the legality of the drug, but whether the drug has impaired the driver’s mental or physical ability to the point that they cannot safely drive. A charge for OWI involving prescription drugs is treated just as seriously as one involving alcohol. The penalties are the same and can include jail time, heavy fines, license suspension, and mandatory substance abuse evaluation.

What Types of Prescriptions Can Cause Impairment?

Many classes of medications can potentially cause impairment severe enough to warrant an OWI charge. These often include drugs that affect the central nervous system. Common examples of prescription medications that may lead to impairment include:

  • Opioid painkillers: Pain relievers such as oxycodone, hydrocodone, and morphine, which can cause drowsiness and slow reaction times.
  • Benzodiazepines: Medications like Xanax (alprazolam) or Valium (diazepam), prescribed for anxiety or sleep, can severely impair motor skills and judgment.
  • Muscle relaxers: Drugs used to treat muscle spasms can cause sedation.
  • Antidepressants and antipsychotics: Some medications in these classes can cause significant drowsiness, especially when first starting treatment or changing doses.
  • Sleep aids: Even common, non-benzodiazepine sleep aids like Ambien (zolpidem) can have lingering effects.

If a drug carries warnings about operating heavy machinery or driving, it can potentially be the basis for an OWI charge if it compromises your ability to operate a vehicle safely. It’s important to discuss driving risks with your doctor and follow their advice.
