Allergic Rhinitis
"I began taking this medication on Saturday and by Monday (3 days later), I felt awful. I had a general feeling of illness; nausea; and pain in my back, legs, arms and hands to the extent that I had to take Oxycodone. The med did seem to be working somewhat because I was feeling less drainage in my throat, but not enough to cut out Claritin and Sudafed. In case my symptoms were the result of something else, I&#039;m going to try Montelukast again in a couple weeks."
