Allergic symptoms and Allergy Drops
I have allergic symptoms (such as sneezing, runny nose, nasal congestion, itchy and dry nose, itchy eyes) all year round for 7 years. The symptoms sometimes are severe, sometimes are mild. I had two times allergy tests (blood test) this year and all the results are normal (specific allergens are <0.35 kU/L, IgEs are 4 IU/mL). I took OTC antihistamine medicines (Claritin, Zyrtec, Alavert etc.), they didn’t work for me. I tried prescription sprays (antihistamine + anti-inflammatory). They worked for me at the beginning. After several months of use, I felt less and less helpful. Recently I got to know the Allergy Drops (a sublingual allergy immunotherapy). Does anybody know the Allergy Drops can treat the allergy symptoms even though my allergy blood test result is normal?
Any advice is welcome. Thanks!
