DUI: Can Benadryl and Alcohol Create a Cumulative Effect?

According to toxicologists for the Broward County State Attorney’s office, yes.

A recent study of Florida DUI Cases indicate that many individuals using Benadryl as a sleep aid achieve a heightened sedative effect when mixing the medication with alcohol.

According to pharmacists,  Benadryl is an antihistamine known as diphenhydramine. This over the counter medication is readily available without a prescription and is commonly used to treat common allergies. In some cases, Benadryl is used to fight insomnia.

A recent study indicated that many individuals using Benadryl as a sleep aid achieve a heightened sedative effect when mixing the medication with alcohol. Combination of the two substances is also known to cause dizziness and bursts of euphoria in the user.

DUI prosecution can be expected to include the use of expert testimony by a qualified toxicologist in and for Broward County where there is evidence of a DUI defendant’s having been under the influence of these two substances.

According to Defense Attorney Moore, combatting this evidence should include an attack on studies that involve primarily elderly subjects. Age is an important factor in cases involving the cumulative effect of combining antihistamines and alcohol. For some reason, younger individuals are far more resilient to any so-called compounding effect when dealing with the consumption of these two substances.

Lack of concentrations in State toxicology reports should also be argued in great detail.

William Moore has significant knowledge of anticipated expert testimony of Broward County toxicologists and is available for comment on a variety of combinations as pertaining to impairment.
