Alternative ways to treat asthma apart from inhaler?

Pills/shots: An older treatment was oral theophyllin a cousin of caffeine that was taken every 6-12 hrs depending on the form. The side effects included hyperactivity and occasional seizures if taken in excess. The inhalers use the lungs as a delivery site, and proper use simplified treatment and control.Proper training in inhaler use is often not given and leads to poor effectiveness.
