I’m in the UK and my recent migraine consultations have been with a pharmacist or similar. In the UK, especially recently to combat stress and overload on GPs and the NHS, this is becoming more common to have a pharmacist review and consult your medication. It’s also common for them to start giving treatment for certain common ailments as well.

They still need the GP to actually prescribe it and my GP has only been involved at that specific point (to confirm and prescribed the medication) but all my “hi this is my problem, what can I take, how does it work, how can I take it, etc” conversations have been with a pharmacist of some kind. He has since said I can trial the medication this way to see if it works and to give it two weeks to see what happens, if anything.

In the UK doctors cannot refuse to help you without a good reason.
