Hello. Thank you for asking at HCM. I went through your history. I would like to know which type of allergy you are having - nose allergy, skin allergy or anything else. However, I would like to make suggestions for you as follows: 1. Personally I would suggest you to get allergy testing done which may identify the substances you are allergic to and also to know the measures to avoid them. Avoidance is the best strategy for allergy. 2. Any anti-histamine drug like Hyrax (Hydroxyzine) can control allergy symptoms. They can not cure allergies. 3. If you are having allergy symptoms if you are off the drug, personally I would suggest to continue drug in such a way that it minimizes your symptoms. 4. Sedation is a common side effect of Hyrax (Hydroxyzine). As you are troubled by sedation, personally I would suggest you drugs causing less sedation like fexofenadine or levocetirizine or ebastine etc. 5. For permanent relief from allergy, as mentioned above, avoidance is the best strategy. However, an Allergy specialist may suggest you Specific Allergen Immunotherapy after allergy testing which may offer long term relief from allergy symptoms. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
