Medicines Warning As Hay Fever Season Kicks In

Road Safety body GEM Motoring Assist is warning hay fever sufferers to check their medicines carefully before getting behind the wheel.


GEM chief executive David Williams says: “Some medicines, including those used to treat hay fever, can have an effect on your ability to drive safely. They could make you tired, dizzy or groggy, and they can compromise your vision and reaction time. That’s why it’s so important to check with your GP or pharmacist, and to read any warnings contained on the labels of the medicines you plan to take.

“The same road traffic laws apply to therapeutic drugs as to illicit substances, so if your driving is impaired and you cause a collision, you risk prosecution and the loss of your licence.

“The newer types of antihistamine tablets should not cause drowsiness, though if you do find yourself become drowsy after using antihistamines, you must avoid driving.”


GEM’s recently-revised free leaflet, Don’t motor on meds, offers sensible and straightforward advice for anyone concerned about how hay fever remedies and other medication may affect their ability to drive safely and legally. The leaflet answers a number of questions dealing with prescription medicines, over-the-counter remedies and what the law says about driving while impaired by drugs.

Safety Checklist

David Williams recommends a safety checklist for any driver likely to need a hay fever medicine:

  • Ask your doctor or pharmacist if a medicine could affect your ability to drive. Be particularly careful if you are using a medicine for the first time.
  • If you do experience potentially dangerous side effects from a medicine, don’t drive. Organise a taxi or a lift from a friend if you need to travel.
  • If you find a particular medicine is making you sleepy, consider asking if there is a non-sedating alternative available.
  • It’s not just prescription medicines that can cause drowsiness and other potentially dangerous side-effects. So, check with your pharmacist if you plan to use an over-the-counter drug.
  • If you’re unsure about the warning given on the medicine you’re using, ask your doctor or pharmacist to explain any risks… before you drive anywhere.
  • Be aware that drinking alcohol while taking medicines can intensify drowsy side-effects. Even small amounts of alcohol mixed with medicines can make it dangerous to drive.
