Driving and pharmacy medications
Many road users are unaware the pharmacy medication they are taking could be impairing their driving, particularly if mixed with alcohol.
What to do
- always ask if it is safe to drive on your medication
- read labels to see if your medication may affect your driving
- talk with your doctor or pharmacists to see how medications may affect your driving
- ask if there is a medicine that may be less impairing
- be aware medicines may affect your driving more when you first start taking them.
- don't stop medication or alter your dose without speaking to your doctor first
- don't drink alcohol if you are planning to drive
- use alternative transport such as public transport or taxi
How can medicines affect driving?
The impairing effect of some medicines can be equivalent to a BAC (Blood Alcohol Content) of 0.05% or more so it is important to understand how your medicines affect your ability to drive.
Common side effects of some medications are:
- drowsiness or tiredness
- dizziness or feeling faint
- blurred vision
- shakiness or unsteadiness
- confusion and poor concentration
- slower reaction time
- mood changes and anxiety
