This depends on the type of medication and how necessary it is. The most important medications to decide on are blood thinning medications and diabetic medications.
blood thinning medications – you should already have had a plan to cease these a numbers of day prior, as advised by dr le page, the hospital or anaesthetist. They should also not be taken on the day of the procedure.
diabetic medications – this depends on the type and some should have been stopped a few days prior (eg. Jardiamet) or reduced dosage the night before. On the day, they should not be taken (the hospital will check you blood sugar when you turn up and address this if necessary)
other medications:
important medications should be taken with sip of water in the am on the day of surgery (unless advised otherwise) – examples are blood pressure medications, b-blockers or anti-depressants.
non-essential medications can simply be withheld – eg. Cholesterol medication.
