I had previously taken singulair for asthma and seemed fine! So fine I stopped taking singulair end of December 2006. Recently, I noticed I needed my inhaler a couple of times a day--I exercise vigorously 5-6 days a week. I asked my GYN to re-prescribe. Started my first 10 mg dose Wednesday evening (!8Apr), Friday afternoon I had a sore throat..pretty severe by day's end--Saturday I had full blown bronchitis (upper respiratory infection) Had to dust off my nebulizer. Love Merck's disclaimer: Side effects are generally mild and vary by age, and may include headache, ear infection, SORE THROAT, and UPPER RESPIRATORY INFECTION. Side effects generally did not stop patients from taking SINGULAIR. IS IT WORTH IT? DOES IT GET BETTER?
