Beclomethasone
"I've been on Qvar 40 for 4 years because of drastically out of control asthma. It works great for controlling the asthma but it aggravates a heart condition that I have- PVC- so I'm unable to use it as prescribed. Instead of twice a day I use it once every other day. About 2 months ago I ran out and couldn't afford to get to the doctor for a new prescription so I just went without it. My breathing got so bad that I felt like I was living on my rescue inhaler. Just finally got my new prescription today and after one use I'm already feeling better. 

The only downside to this medication is the cost and since I don't have insurance it's all out of pocket. "
