There are patient assistance programs that provide meds for no cost. They usually have an income limit and say if you have insurance you don't qualify. However they will make exceptions and I've found they are quite generous with the exceptions. I'm on medicare and it just doesn't cover several of my meds and those meds are hundreds or over $1000 and I just apply, include a note explaining that I technically don't qualify but am asking for an exemption because there is no way I can afford the med on my income (I usually try to tell them what the cost would be). And I've always been approved.

I don't know that they will definitely make an exemption when you have commercial insurance but it's worth a try. And your mother's inhaler should be covered that way; mine is and has been for many years.
