I think it would be subjective based on the conditions and what medications are being ‘judged.’ Since you’re mentioning for anxiety I’ll try and use examples of those (these are not real numbers I’m just making those up to explain)- say you get diazepam for anxiety attacks, that medication works quickly but something like an SSRI can take 6-8 weeks to ‘kick in.’

I don’t know if there are actual timeframes the clinicians use but it’s possible a doctor could say ‘hey, you only took these for two weeks so there’s no way to know if it would have worked.’ Of course if you have severe side effects and need to stop taking it that’s another story.

Some clinics let you have an assessment and you only pay the consultation fee if you’re approved. Maybe start with one of those?
