There are programs through pharmacy companies that do supply people like us meds.
One such program is Needy Meds. I though attempted to get the
Spiriva through such a program. They turned me down on the Spiriva though. Said my husband made too much money. My husband roughly makes 20 grand a year. That is poverty level actually, but still we make too much money. I though was approved on my rescue inhaler.
But, like allmymarbles suggested, possibly try these natural products.
