Hello Thank You for contacting HCM. Your description is telling that you have chronic allergy problem. You did not mention your age. If i were your treating doctor then i would suggest you following things: First and most important thing is that you need to find the cause of allergy. On your part it can be achieved by looking closely at your daily routine. You need to observe what particular thing, food, etc is causing the allergy to start. Once you find it, you nee to prevent it. In the meanwhile take Montelukast once daily for 1 month. Research has shown that it decreases sensitivity to allergy. Cetrizine one at night for 1 week in case of allergic response. try to avoid dust I would also suggest you to under go allergy testing at allergy clinic which will tell that you are allergic to what specific thing. The results will help an allergist to prescribe you immunotherapy to that specific allergen and it will improve the problem. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. Wishing you good health.
