I am 28 years old male, I have a allergy issue from past 4 years now. I have consulted diff doctors got me complete allergy test and on the basis of report the laboratory from where the test was done, they prepared some IMMUNOTHERAPY injections with schedule and I took all the injections as per schedule for about 8 months but still I am in same pain. Almost every alternative day I take Cetrizine Tab. I am worried if it effects me in some other way in taking the dose of Cetrizine always. Please suggest the best for me as I am really tired of this problem in me.
