No I didn’t try it. It was an option the specialist offered but as I’d paid privately it was the only chance to try Fezolinetant, unless I paid again as a GP can’t prescribe yet. Oxybutynin can cause tachycardia so I was wary even though my medication was not listed an an interaction on the BNF website. BNF is only available in the UK | NICE
I hadn’t heard of oxybutynin before and all the others listed British Menopause Society as non hormonal medication for hot flushes interacted with my heart medication.
