“Does non-antihistamine medicine exist?”

I work in a Platinum mine that produces platinum salts. So the medical requirements that they conduct every 3 months include a skin prick test for rhodamine, iridium, brass, etc. to see if one could be reactive otherwise no job offer at all. So my challenge is that I have sinuses and every time I need to do this test I need to wait a month to let all the allergy tablets or sprays leave my system to keep the antihistamine from fighting the control of the skin prick test. I hope you understand what I mean. My aim is for the test to have a reaction on the control so that the nurse won't think I'm cheating by using drugs and lay me off. Is there any medication apart from antihistamines that I can use to fight off my sinus triggers? Thank you, doctor.

I have chronic sinusitis and the triggers that I've kept tabs on are food smells, perfume, change of temperature, or just going outside or inside for a minute. Sometimes these are triggers but sometimes they won't trigger me at all. I use Texa allergy tablets and Avamys nasal spray and at some times, Iliadin. I usually also boil a home remedy made of honey, lemon, garlic, green tea, and ginger and get vitamin C tablets.

Well if I'm triggered the inner wall of the back of my nose will be irritated sharply then ill sneeze nonstop and blow my nose for 30 minutes and it stops again. sometimes when I'm not on the antihistamine I could blow my nose all day as if I have the flu. I'm not taking any other chronic treatment and I have a 11 month old baby so the last time I was on meds was during and shortly after my pregnancy. Please note that I take iron supplements for red blood cells at times.
