Do You Take Medication? Be Extra Cautious!

Some medication may have effects on alertness, vision, physical coordination and behaviour. Before getting behind the wheel, make sure that you can do so safely.

Knowing about your medication's side effects is important!

When you are prescribed medication – or if you buy some over the counter – ask your physician or pharmacist about any side effects that could affect your driving.

Here are some side effects brought on by medication

  • Confusion
  • Blurred vision
  • Decreased reaction times
  • Drowsiness
  • Dizziness

Beware of mixing: different kinds of medication don't always get along!

Some prescription or over-the-counter medications do not have side effects.

However, when combined with another medication, they can cause side effects that are incompatible with driving a vehicle.

Remember for many medications, a glass of alcohol can have adverse effects on judgment, reflexes, vision and balance.

If you have to get behind the wheel, make sure that your “cocktail” won't interfere with your ability to drive.

Have you been prescribed a new medication, or has your dosage changed?

Before getting behind the wheel, check to make sure that you are not experiencing side effects that could hinder your ability to drive.

Stopping medication does not mean no more danger. Quite the contrary!

Stopping certain medications – or decreasing the dose – may cause important withdrawal symptoms.

Ask your physician or pharmacist about possible symptoms. That way, you will know whether you can drive safely or if it is better to wait a while.

See our sections entitled Effects of Drugs and Medication on Driving and What the Law Says on this subject.
