Medications are expensive, but many of us get physician samples from our doctors. I had one specialist allow me to try singulair through samples and it worked well. It helped me to get through a humid summer. Now, I take accolate and it is also helpful for me.
Many doctors also carry inhalers that they can give to patients.
Perhaps this is another route to go through. I know that my doctors do give medications away to patients who cannot afford them. Fortunately most of my medications are covered through the CF program.
