Prescription drugs can intoxicate you just as strongly – and in many cases worse – than alcohol. This means that you need to be careful whenever you take a prescription drug and get behind the wheel. Always check the label of your drugs carefully, and look for warnings that you shouldn't drive, or shouldn't operate heavy machinery while taking the drug.
Even if you think you're sober enough to drive, consider the drug you took. If there is any potential that the drug could intoxicate you or impair you in any way, don't drive. Even if you feel sober, the drug could be affecting your judgment. It's better to play it safe when it comes to pharmaceutical drugs and driving. Being careful like this could save your life, and the lives of your passengers and others you're sharing the road with. It could also prevent you from getting arrested.
It doesn't matter if your doctor prescribed your drug. If it has an intoxicating effect on you, a police officer could pull you over and arrest you for intoxicated driving. Also, if you cause an accident and injuries while intoxicated by the drug, you could find yourself spending time in jail.
Every prescription drug DUI case is different. In some situations, those accused of this offense can successfully defend themselves against the charge in court. At the very least, DUI defendants may be able to employ legal strategies to try and get their punishments reduced in the event that a conviction is likely.
