I have been on Singulair for about 2 1/2 years...I thought it was a miracle drug. The asthma I had been strapped with since I was 7 yrs old (40 yrs old now) seemed to subside greatly. Last week, I went to the doctor with another ear infection...something that has been extremely common in the last several years. I had never before had ear problems..even as a child. My mother heard Singulair advertised on TV and one of the possible side effects was ear aches and ear infections. Could Singulair be the culprit? Is this why both of my ears are stopped up going on 6 days now? Ugh...I WILL be contacting my doctor tomorrow!
