I Have Asthma. I Use Flovent 2x2 But Lately It

I have asthma. I use Flovent 2x2 but lately it isn't controlling my asthma so I've been increasing to 5 or 6 puffs daily. Asthma is exercise or allergy induced. Have used Symbicort in the past (great for 5 years) but became allergic to formeterol (laba). I need another steroid/laba combination maybe like salmeterol but I'm not sure if I can take a different laba. Also I have not tried any anti leukotrienes. I need to see a respirologist who really knows meds..
