Introduced back in March 2015 a drug driving law came into force within and England and Wales.
If you are taking your medicine as directed and your driving is not impaired, then you are not breaking the law.
It will remain an offence to drive while your ability is impaired by drugs and, if in doubt, you should not drive.
To find out more ask your doctor or a member of the pharmacy team.
