I fall into this category, diagnosed with CRMS, with R117H & delta-F508, and I just started taking Kalydeco 3 weeks ago. Non-classical CF-related metabolic syndrome is still a serious problem, albeit it may hit you later in life. I'm almost 42 and didn't start having real concerns until a few years ago, with a steady MAI/MAC infection and occasionally a few other bugs like Strep G. I tried to keep it mostly under control, but it seems that things were going downhill with the aging process. This past summer, a lot of my hair thinned out, my nails were getting brittle, and my periods became irregular, like I was starting perimenopause. Now, 3 weeks into taking Kalydeco, I feel like a new woman. Not only have I quit coughing up daily infected sputum, but my body feels like I'm getting my hormones back in balance. To be totally honest, I got some volume back in my face and in my bust line, and not on my belly; my curves are filling out exactly where I want them. I feel like a teenager again! My mood is up, and I'm thinking clearly, like I must have been living in a fog before; I'm having a great sense of awareness, energy and tranquility, like I'm more "me" than I've ever been. It's an amazing medicine.
The only issue that I've found with Kalydeco is that I have to be really careful about scheduling food and drink around it. Previously, I never drank that much alcohol, except for a couple of drinks socially, but I feel that I need to be even more careful with drinking. I did try a drink in the middle of the afternoon, a few hours before my dose of Kalydeco, and didn't find too much interaction. But when I tried 1 drink right after having Kalydeco with dinner, my face flushed red. Seems like an interaction to me. So, in the future, I won't have a drink within a couple hours of taking it, if at all. The label isn't clear about this interaction, as they might not have much evidence, but this is my advice from my personal experience. At least my husband doesn't drink at all, and I never drank that much, so it's going to be very easy for me to be good about not having any alcohol within a few hours of Kalydeco.
Otherwise, I feel so grateful that I'm taking this amazing medicine and don't have to worry too much about whether or not I'm ever going to meet my future grandchildren.
As for the insurance cost issue, that's the only negative I can say about this medicine. If it can cure your mild CF, like it seems to be curing mine, then it's worth it. Just because your CF is mild now, doesn't mean that it will stay mild when you get older. Also, your employer shouldn't have to pay higher premiums based on your care. The Affordable Healthcare Act changed a lot of things. If anything, you could do some activism on where you stand politically with specialty drug price gouging, standing on the side with a sustainable insurance system. But you should still take it if it can help you.
