Some hay fever medications can violate drug-driving laws

Weather conditions in the UK are improving as summer approaches, but pollen counts continue to increase.

About 20% of UK residents suffer from hay fever, and an estimated 95% of them are allergic to grass pollen. If you suffer from hay fever and wish to drive, your allergy can cause several problems.

Some of the symptoms of hay fever, such as sneezing fits, itchy eyes, and runny noses, can make driving more difficult, as these symptoms could impair your vision or distract you. Sneezing fits can be especially problematic when you are driving at high speeds.

To fight these symptoms, many drivers use common, over-the-counter (OTC) drugs, such as antihistamines. But, using OTC drugs to fight hay fever can cause problems, including drowsiness and vision impairment. More problematic is that OTC drugs are subject to the same drug-driving laws that cover illegal substances, such as cocaine.

According to the NHS, antihistamine tablets contain diphenhydramine and chlorphenamine and are likely to cause drowsiness. Simon Rewell, Road Safety Manager at Insure the Box, explained: “Drivers using hay fever medication could experience side-effects that impair their ability to drive safely. Crucially all drugs, whether prescribed, over the counter or illegal, are covered by the same laws, so driving under the influence carries the risk of a fine or ban.”

Penalties for a drug-driving conviction include an unlimited fine, a minimum of a one-year ban on driving, a prison sentence of up to six months and a criminal record.

If you suffer from hay fever, it is prudent to use OTC drugs that contain cetirizine or loratadine, as they are less likely to cause drowsiness and impair your driving ability.
