I had been taking Singulair to help with shortness of breadth. Then, on next prescription, pharmacy filled my prescription with a generic Singulair . The generic singular is not working and I feel shortness of breadth. I am 66 years old male. I never had this problem until earlier in this year (I believe probably due to LPR acid reflux , which is under control now). What is the best course of action for me? Thank you very much -- M. A.
Hello, There should not be a difference in efficacy between branded Singular and generic Singular, unless (1) dose is different; (2) levocetirizine was present in the previous time. Acid reflux should be treated with tablets such as omeprazole, or omeprazole taken first thing in the morning. If shortness of breath, please see a Chest Physician for Chest X-Ray, lung function tests to see if you will require inhalers. Best Wishes.
