Cough medicine effect on breathalyzer

Asked over 2 years ago - New Orleans, LA

What effects, if any, does NyQuil have on a breathalyzer reading results. Was arrested for DUI and agreed to breathalyzer since I hadn't been drinking much and much earlier in the day and failed. I had taken NyQuil on the way home. Recently learned that this could influence breath reading.

    Answered . In my opinion, not much unless you drank a few bottles the minute before you blew.
