I have been searching trying to find the answer, but after days of trying, I have yet to find it. I have recently started Plegridy and have started to develop onychoptosis. When the nails fall off, it's not bloody, but as I'm diabetic this does pose a health risk. I have been searching and searching to no avail. When I was on Copaxone, I didn't have this reaction, but now I'm on Plegridy and I've been loosing nails quite often. Is this a known side effect from interferon, or am I developing something I should see a podiatrist about?
Nail fungus or nail loss is not a known side effect of interferons but is certainly common in Diabetics. You should inform your primary care doctor or diabetes specialist.
