Understanding How Over-the-Counter Medications Like Cough Syrup Can Lead to DUI Charges


In Florida, driving under the influence (DUI) is typically associated with alcohol or illegal drugs, but it's important to know that over-the-counter (OTC) medications like cough syrups can also put you at risk for a DUI charge. When we take medications containing alcohol or other substances, like dextromethorphan or codeine, it’s easy to overlook how these might affect our driving abilities. Florida law is clear: if a substance impacts your ability to drive safely, whether it's prescription medication, alcohol, or even cough syrup, you could face DUI charges.

Let’s dive into how Florida law handles DUI charges involving cough medicine and what you can expect if you find yourself in this situation.

Florida’s DUI Law and Cough Medicine

Florida Statute 316.193 defines DUI as driving or being in actual physical control of a vehicle while under the influence of any substance that impairs your normal faculties. While this statute commonly applies to alcohol, the law also extends to other substances, including legal medications. What this means is that if a law enforcement officer determines you’re impaired by an OTC medication, such as cough syrup, you could be charged with DUI.

The key here is the term "impairment." Cough syrups, especially those containing ingredients like codeine or dextromethorphan, have the potential to cause drowsiness, delayed reaction times, or other side effects that affect your driving. Officers are trained to assess whether a driver is impaired based on various cues, such as slurred speech, unsteady movement, or difficulty following instructions.

How Officers Identify Impairment from Medication

When you’re pulled over, officers may observe your behavior for signs of impairment. If they suspect impairment but detect no smell of alcohol, they may ask about any medications you’ve taken. Common signs of impairment from cough syrup can include:

  • Drowsiness or sluggishness
  • Confusion or disorientation
  • Inability to focus or concentrate
  • Slurred or slowed speech

If the officer suspects that medication is the cause of your impairment, they may call a Drug Recognition Expert (DRE) to assess you. DREs receive specialized training in recognizing signs of impairment from various substances, including OTC and prescription medications.

Chemical Testing and Its Role in DUI Charges

Florida law allows for the use of chemical testing to determine impairment. While breath tests are most common for alcohol-related DUIs, officers may also request blood or urine tests to detect other substances. If you’ve taken cough syrup, the active ingredients, such as dextromethorphan or codeine, may be detected in these tests. Refusing a chemical test in Florida can lead to penalties, including license suspension under Florida’s Implied Consent Law (F.S. 316.1932).

If you comply with the test, the results can serve as evidence in your case. The presence of cough syrup ingredients in your system alone, however, is not enough to convict you of a DUI. Prosecutors must also prove that your normal faculties were impaired due to the medication.

Potential Penalties for a DUI Involving Cough Medicine

Florida takes DUI offenses seriously, and a conviction can lead to penalties similar to those for alcohol-related DUI cases. Here are some of the potential consequences you might face:

  • Fines: First-time DUI offenders may face fines between $500 and $1,000, while repeat offenses can lead to higher fines.
  • License Suspension: A DUI conviction often results in a suspended license. For a first offense, you could face a license suspension of up to six months.
  • Probation: DUI convictions often come with probation terms, which may include attending DUI school and community service.
  • Jail Time: While first offenses may not lead to jail time, aggravating factors, such as an accident or injury, can increase the chances of a jail sentence.

Legal Defenses for a DUI from Cough Medicine

If you’re facing DUI charges from taking cough medicine, there are several possible defenses to consider. Each case is unique, and an experienced DUI defense attorney can help identify the best approach for your situation. Common defenses include:

  1. Lack of Impairment: Showing that you were not impaired is one of the most straightforward defenses. If your faculties were not impacted to the extent that they would compromise safe driving, this could be an effective argument.

  2. Improper Testing Procedures: Officers must follow specific protocols when conducting chemical tests. Any deviation from these procedures could render test results inadmissible.

  3. Unlawful Traffic Stop: Law enforcement officers need a legitimate reason to pull you over. If you were stopped without probable cause, any evidence gathered after the stop may be dismissed.

  4. Medical Necessity Defense: If you have a prescription for the medication in question and took it as directed, this defense may apply, though it can be challenging since impairment is still at the core of the DUI law.

Steps to Take if Charged with a DUI for Cough Medicine

If you’re charged with a DUI related to cough medicine, taking the following steps can help protect your rights:

  1. Consult an Attorney: DUI cases involving legal medications can be complex. A knowledgeable DUI defense attorney can analyze the details of your case, gather evidence, and build a defense.

  2. Document Your Medication: Keep records of any medications you were taking, including the dosage and frequency. This information can be relevant to your defense.

  3. Follow Court Orders: Until your case is resolved, make sure to adhere to any court orders, including license restrictions or probation requirements.

Common Misconceptions About Cough Medicine and DUI Charges

Many people believe that because cough medicine is available without a prescription, it’s safe to use before driving. However, the reality is that many OTC medications come with warnings against operating heavy machinery. Even if it’s legal to buy cough syrup, using it irresponsibly can lead to serious legal consequences.

Another misconception is that as long as you aren’t drinking alcohol, you’re safe from DUI charges. Florida law doesn’t distinguish between alcohol and other substances when it comes to impairment. Whether it’s cough syrup, prescription painkillers, or even certain cold medications, anything that impairs your driving can lead to a DUI charge.


FAQs: Can You Get a DUI From Cough Medicine in Florida?

How can cough medicine impair my driving?
Cough medicine often contains ingredients like dextromethorphan or codeine, which can cause drowsiness, slow reaction times, and impair focus. These effects can make it unsafe to operate a vehicle, leading to a DUI charge if an officer determines that your ability to drive is compromised.

Is it illegal to drive after taking any medication?
Not all medications will result in DUI charges. However, under Florida law, driving after taking any substance that impairs your normal faculties is enough for a DUI charge. This applies to both prescription and over-the-counter medications if they impair your ability to drive safely.

What should I do if I’m pulled over after taking cough medicine?
If you’re pulled over, stay calm and polite. You can inform the officer if you’ve taken any medication, but avoid admitting to impairment. If the officer requests a chemical test, you should comply, as refusal can lead to immediate license suspension in Florida. Contact an attorney as soon as possible to discuss your options.

Can I use a prescription defense if I’m charged with DUI from medication?
While having a prescription can support that you were legally using the medication, it doesn’t guarantee immunity from DUI charges. Florida law focuses on impairment rather than the legality of the substance. An experienced attorney can help argue that you took the medication as prescribed and were not impaired.

Can I be charged with DUI if I only took the recommended dose of cough medicine?
Yes, even taking the recommended dose can lead to impairment depending on how the medication affects you. If law enforcement believes your driving is impaired, they can charge you with DUI regardless of the dose.

What’s the difference between a DUI charge from alcohol and one from medication?
In Florida, the law treats DUI from alcohol and DUI from medications similarly, focusing on impairment rather than the substance. The penalties, legal process, and defenses are often the same, though cases involving medication may involve additional medical evidence.

Do over-the-counter medications show up on chemical tests?
Some ingredients in OTC medications can be detected through blood or urine tests, especially if the medication contains substances like codeine. However, these tests alone don’t prove impairment, so prosecutors would still need to establish that your driving was impacted by the medication.

Can a DUI lawyer help if I’m charged with DUI from cough medicine?
Yes, a DUI lawyer experienced with cases involving legal medications can help build a defense. They may argue that you were not impaired, challenge the traffic stop’s legality, or question the accuracy of the officer’s observations and test results.
