Substance impaired driving is a sizeable and serious problem. As a health professional you can help your patients make good choices about whether or not they’re safe to drive.
Road crashes caused by substance impaired driving, occur much more often in New Zealand than previously thought. People are uninformed about how medication and drugs can affect their driving.
As a health professional, you can help your patients be informed about how their medication – and other substances they may be taking – can affect their driving. You can help them make good choices about whether or not they’re safe to drive.
What is substance impaired driving?
Substance impaired driving is when a person’s ability to drive a car is affected because they have taken a drug or medication, a combination of these or combined them with alcohol.
It’s illegal to drive while impaired and Police will enforce this law.
Five types of medications most often prescribed by New Zealand doctors make up three-quarters of those that may impair driving:
- analgesics
- antidepressants
- heart medications (Beta blockers/Calcium channel blockers)
- antihistamines
- sedatives
Five less common prescription medications make up most of the rest:
- antipsychotics
- anti-epilepsy drugs
- substance dependence treatments
- anti-nausea medications
- anxiolytics.
These 10 medications account for over 95 percent of prescription medications that may impair driving in New Zealand.
Talk to your patient about how their driving could be affected if they’re:
- taking one or more of these medications (or)
- taking some of the variants sold as ‘pharmacy only’ (or)
- taking over-the-counter’ medications such as anithistamines or cold and flu preparations.
