... anaphylaxis for decades. A few years ago I got sick and my doctor put me on Gabapentin. In that time I was exposed to my worst allergy I grabbed my epi pen and inhaler and waited for it to hit. It was so mild I didn't even need any of it. I share this because I have now been on this medication for a few years. I can go out to eat again I still get mildly sick if exposed but it's gastro and I loose my voice.
