Feb 2010 I suffered heart & lung failures caused by blood clots for which I take Warfarin 4mg everyday. I used to take Aerius for my allergies, but was told in the Spring (by my pharmacist) to stop. My Cardiologist now tells me I should be able to safely resume the use of Aerius. Also, I do have a hole in my heart. As well I have asthma (brincanyl & symbicort). I also take crestor, coversyl, el troxin & percocet (1 per day). I would sincerely appreciate your best advice to my dilemna. P.S. My respirologist bows to my cardiologists decision & tomorrow, March 30/11, I will be consulting with my GP & pharmcist. Thank you again.
