Hey all you super knowledgeable people...

Is it possible after a few years of taking a bc for it to just suddenly not be compatible with your body anymore?

I was able to take Tylenol/Ibuprophen/Alieve for years and now it makes my jaws swell and I drool. I think its safe to say HBC can do the same (not cause the same effects, but become allergic suddenly).
