Hi, I've started Montelukast for uncontrolled allergic asthma but i'm finding i am getting constant colds whilst on it, largely a sore throat and a large increase in the production of thick green mucus which is actually making my breathing worse. Symptoms resolve on stopping montelukast.

Has anyone else experienced this? Im frustrated as at first it really seemed to help and my sleep was improving loads. Its not listed as a side effect on NHS website. I have a FENO test next week and i guess i should keep taking it until i see my consultant but that wont be for weeks....
