Whoa, Nelly. Regardless of whethr or not you use Singulair you absolutely positively MUST always carry around an emergency albuterol sulfate inhaler. MUST. Do not pass go. Do not collect two hundred dollars. While these cost as much as sixty dollars each in the United States Wal-Mart had a generic brand for sale (in store only) for less than ten dollars. I also question the use of a blood pressure medication for anyone suffering asthmatic attacks unless absolutely positively necessary. Blood pressure medications work by reducing the ability of the heart to inclrease blood pressure in an emergency. Blood pressure rises as a compensatory reaction when there is an asthmatic attack. As long as it does not progress to the point where there is an acute hypertensive crisis, short periods of elevated blood pressure during an asthmatic attack may mean the difference between living and dying. Despite this fact, many physicians routinely prescribe blood pressure meds to asthmatics.
I take Singulair for my asthma and it works wonders, but I am told, it's effect on allergies is very minimal. I have lots of allergies too but I have noticed, that over the counter meds like Alavert (or Walgreen's version) or ones similar, are better with allergies. My father says Singilair does help with his nasal polyps, but he also agrees it doesn't do anything for allergies. I would really invest your money in an inhaler like Symbicort or Flovent (Steroids), since I dont think it's your asthma that is flairing up-it sounds like your allergies, and I am in AZ too...
