You can take symbicort, however it being a steroid aggravates the heart pressure, although it reduces the wheezing in the body.
I suggest you bring the cough down with a gentle steroid like asthalin and then try out symbicort, Duolin etc.
But health foods like garlic, apples, wheat, etc helps a lot in bringing the wheezing down. You can get the info from healandhealth, I too am an asthmatic and feel for you. But Foods, fruits helps a lot too as it has done for me.
