If you are a diagnosed diabetic, in the UK, you have regular check-ups with a diabetic nurse at your doctor's surgery. You get regular proper blood tests. You get free medication as needed. The NHS works well with this, from my experience.
I am not trying to knock the skills of the pharmacist here, but they seemed to be implying people may not be on the right medication in the advert. They seem to be having a go at the skill of the doctor and diabetic nurse. Why? Is there really a medical concern that people are on the wrong medication from their doctors?
It is not like someone with a cold or a some minor ailment where they pick their own medication, and so may well benefit from advice at a pharmacist - diabetes is much more managed than that and you get prescribed medication, and advice from a dietician, and so on.
If this was advertising for people concerned they may have diabetes then it may make sense - it will be a lot easier than going to the doctor and may catch people early (and recommend seeing a doctor as a result), but the advert seems to be for people who know they are diabetic and have concerns that they are not on the right medication. Very odd. If someone was concerned they can just ask their diabetic nurse or doctor. The pharmacist can't prescribe changes to their medication, so the only result of talking to the pharmacist is either a recommendation to go back to the doctor anyway, or to sell some extra medication that is not prescribed.
Is this just FUD (Fear, Uncertainty and Doubt) used to try and sell extra, paid for, treatments through the pharmacy. Next thing they will start selling placebos
I am surprised that the advert is even allowed.
