What about driving while taking co-codamol?
Co-codamol may cause drowsiness, dizziness, confusion and blurred vision. If affected do not drive or operate machinery.
In March 2015 a new 'drug driving' law came into force that allows police to use roadside drug tests to check for the presence of prohibited drugs in a driver's saliva. The medicines prohibited by the law include morphine. Codeine is converted into morphine by the liver, which means it may be an offence to drive while you are taking co-codamol. Y
From the Gov website;
Prescription medicines
It’s illegal in England and Wales to drive with legal drugs in your body if it impairs your driving.
It’s an offence to drive if you have over the specified limits of certain drugs in your blood and you haven’t been prescribed them.
Talk to your doctor about whether you should drive if you’ve been prescribed any of the following drugs:
amphetamine, eg dexamphetamine or selegiline
clonazepam
diazepam
flunitrazepam
lorazepam
methadone
morphine or opiate and opioid-based drugs, eg codeine, tramadol or fentanyl
oxazepam
temazepam
You can drive after taking these drugs if:
you’ve been prescribed them and followed advice on how to take them by a healthcare professional
they aren’t causing you to be unfit to drive even if you’re above the specified limits
You could be prosecuted if you drive with certain levels of these drugs in your body and you haven’t been prescribed them.
As long as they are prescribed to you, and you have taken only the correct dose, you will be fine. The warnings about drowsiness etc are std, even in allergy tablets.
As the OP will probably know, the body builds up a resistance to these drugs, so they will actually have less of a chance of side effects, the longer he has been taking them.
