Anyone had this problem, a change of brand, and suddenly the flushing is horrific?

Been quite settled for 6 or so months, been on activis brand. Pharmacy gives me a brand called "nomoud" and overnight I have the constant flushy feel on my face, even when I slightly move.

Annoyed as like I said, it's been a little settled over the past 6 or so months without the constant flushy feel 24/7./

Thought I'd give it a few days but no improvement. Phoned pharmacy and their giving me a headache about it all
