When the sniffles strike, many of us instinctively reach for the nearest over-the-counter cold remedy. After all, getting through the day — especially behind the wheel — feels impossible when you’re congested, achy, and foggy-headed. But here’s the surprising twist: a Peoria DUI Attorney warns that some cold medications can impair your ability to drive just as much as alcohol. Drowsiness, delayed reaction times, and poor coordination are all possible side effects of common cold and flu drugs. If you’re planning to drive, knowing which meds to avoid — and what safer alternatives exist — could help you stay on the right side of the law and out of danger.
1. Diphenhydramine (Benadryl and similar antihistamines)
Diphenhydramine is a widely used antihistamine in many nighttime cold and allergy medications. While it’s excellent at drying up a runny nose and easing sneezing, it’s also notorious for causing drowsiness and impairing motor skills. Research has shown that the impairment from a standard dose of diphenhydramine can be comparable to having a blood alcohol concentration (BAC) of 0.10%, over the legal limit in most states.
Safe alternative: If you need an antihistamine that won’t leave you dozing off at stoplights, try loratadine (Claritin) or fexofenadine (Allegra). These are second-generation antihistamines that don’t cross the blood-brain barrier as easily, meaning they’re much less likely to cause drowsiness or impact your driving ability.
2. Dextromethorphan (found in Robitussin, NyQuil, Delsym)
Dextromethorphan (DXM) is a common ingredient in cough suppressants. While it can be a lifesaver when you’re hacking up a lung, it comes with side effects that can seriously affect driving. In large doses, DXM can cause dizziness, blurred vision, confusion, and slowed reaction times — all of which are a recipe for trouble behind the wheel. Even at therapeutic levels, it can subtly impair focus, especially when mixed with other cold remedies that contain alcohol or sedatives.
Safe alternative: Honey-based syrups or lozenges can ease a mild cough without any risk of impairment. Mentholated rubs and steam inhalation are other safe options. For persistent coughing, guaifenesin (Mucinex) is an expectorant that helps clear mucus without sedating effects, making it a better choice if you plan to drive.
3. Pseudoephedrine (Sudafed)
Pseudoephedrine is a powerful decongestant, great for unblocking sinuses and reducing nasal swelling. However, its stimulant effects can mimic the jitteriness of too much caffeine — think increased heart rate, nervousness, and insomnia. While it may not cause the same type of sedation as other cold meds, it can impair your concentration and reaction time, especially if you feel under the weather or haven’t slept well.
Safe alternative: A saline nasal spray or a neti pot can help clear nasal passages without the side effects of stimulants. Nasal strips that mechanically open the airway may also provide relief, allowing you to stay clear-minded and alert. If you need medication, nasal sprays with oxymetazoline (used short-term) can relieve congestion without as much systemic stimulation, but always check the label and your tolerance.
When to Seek Legal Counsel
If you’ve been cited or arrested for driving under the influence of medication, it’s crucial to understand your rights and your options. A skilled Peoria DUI Attorney can help you navigate the legal system, assess the specifics of your case, and potentially reduce or dismiss charges. When your health and freedom are on the line, getting the right legal advice is just as important as choosing the right medication.
Conclusion
Driving while under the influence doesn’t just apply to alcohol and illicit drugs. Cold and flu medications — especially when combined or taken in higher-than-recommended doses — can lead to impaired driving and even DUI charges. While these medications are legal and widely available, their effects on the brain can make you just as dangerous on the road as someone who’s been drinking. The good news? Many non-impairing alternatives exist, and simple home remedies can often do the trick. Stay informed, stay healthy — and always think twice before medicating and driving.
