No, the rules regarding medication are simple: driving affected is always prohibited and it is your responsibility to know whether you are affected or not. If you make a misjudgement and drive dangerously you may be found guilty of drunk driving, even if a doctor prescribed the medication.

You should always refrain from driving if you have taken one or more medications and exhibit any of the following symptoms:

• You are sluggish, tired, dizzy or groggy.
• You react unusually slowly.
• You have trouble seeing or hearing.
• You have trouble keeping up with conversations.
• You have a hard time performing ordinary, everyday tasks.
• You have impaired judgment.
