Qvar is a corticosteroid that helps control asthma. It has been a great medicine for me. In the last 4 years I have personally experienced a rate hike from $40.00 for 1 Qvar inhaler to $200.00! I need this medicine, but it is cost prohibitive. I have private insurance and am not on Obamacare. If anyone knows of a petition out there to stop price gouging by Teva Pharmaceuticals, please forward a link.
