Sadly, they won’t work any better than the other non-CFC ones. The new propellant is worthless, not to mention corn-based (a major allergen to many).
The first night I relied my new HFA inhaler, I ended up in the emergency room. I had never been in the emergency room for asthma ever before.
Had a similar situation.My Dr. gave me a sample of the new type & after 2 puffs, I had shortness of breath for the entire day. I considered the emergency room but suffered through it.
I’ve been hoarding Primatene Mist for a year. Bought everything on the shelf at Walmart yesterday. I’ve got 65 of them stockpiled. Should last 2 to 3 years.
I think the new inhalers are ethanol powered.
It’s almost funny that something that powers cars, is inhaled for asthma relief.
Only in the United States Congress.
