Does any of this apply?
Book an appointment
Routine follow-up is appropriate for milder ongoing concerns such as changed sleep, reduced concentration, constipation, repeated loose stools from treatment, or questions about medicines.

The article also says
Do not let a confused or drowsy person drive.
Keep them safe from falls, and do not force food, drink, or medicine if they cannot swallow normally.
