Asthma, and dry mouth problems

Patient: So for months I have had dry mouth, and increased asthma reactions and attacks. I have had blood work done with no signs of diabetes or anything obvious that my doctor could see. I have been taking fluticasone propionate, montelukast, and even was taking Prednisone to help my asthma and it helped alot. Currently my asthma is a kinda better but it only is like this under medications. The dry mouth was happening before taking these medications and it something that I have tried to fix with saliva sprays but haven’t worked.

Symptoms: Dry mouth asthma

Doctor:
