Montelukast
asthma, maintenance
"My 16 year old daughter has the typical exercise induced asthma that many of her teammates have and has used an inhaler for a couple of years. Her Dr. advised us to start using Montelukast. We were a bit wary because of the possible side effects, but her Dr. convinced us. About 2.5-3 months later, all of a sudden she started experiencing the awful side effects they warn you about...racing heart, sleeplessness, panic, sadness, hopelessness and anxiety. After a couple days of this we finally read the pill bottle and immediately stopped. It has been a week now and she is better, but still working through the anxiety. Please do your research and ONLY use this medication if you are completely sure you won't experience these side effects!"
