Hi to everyone.

I’ve been on pregabalin for my anxiety and pain for a good 9 months and it’s a great drug, had no issues with side effects at all until recently. I’ve started on antihistamines for hayfever with summer approaching and they seem to be reacting with pregabalin. I’m getting extremely lethargic, dizzy, and horrible fatigue attacks where I just have to go to sleep. I have health anxiety and was convincing myself I’m getting chronic fatigue syndrome but then my partner thought about the antihistamines.

So my questions is has anyone experienced this themselves? Is there an actual interaction as I can’t realky find anything online and I am hoping it is an interaction and I’m not just getting sudden side effects to pregab itself out of the blue as it’s been an amazing drug for me.
