If an over-the-counter drug states that it "may cause drowsiness," when is it safe to drive?

When an over-the-counter drug indicates that it "may cause drowsiness," it is essential to prioritize safety when it comes to driving. This warning suggests that the drug can impair your alertness and reaction time, which are critical for safe driving.

Waiting until the effects have worn off before driving ensures that you are fully alert and capable of operating a vehicle safely. It’s not enough to rely on personal feelings of wakefulness; the drug's effects can vary from person to person, and drowsiness may still linger even if you feel awake. Being fully aware of the potential risks and allowing adequate time for the drug to clear from your system is key to making responsible decisions about driving.
