How do I make sure I am safe to drive?

Always ask your doctor or pharmacist if and when it’s safe to drive while taking your medicines.

  • Do not drive if you have consumed any alcohol or illicit drugs.
  • If you have to take medicine that affects your driving, organise alternative transport e.g. public transport, friends and family, or taxis.
  • Ask your doctor or pharmacist about other medicines you could take that may be less impairing, particularly if you need to drive or operate machinery for work.
  • Do not stop taking your medicines or alter the dose without medical advice as this can also put you at risk when driving.
  • Read the warning labels on your medicines to check if they might be a risk to driving safely.

Some serious and chronic medical conditions that can affect your ability to drive safely may be reported to NSW Road and Maritime Service for your and other road users’ safety.
