Finger nail detachment - Letrozole or Zoladex?

I’ve been on Letrozole for 6 weeks and my finger nails are now detaching. It looks awful and I’ve never had problems with my nails before. I’m also on month 4 of Zoladex. This isn’t listed as a side effect and I’m wondering if anyone else has experienced this with these drugs? I have not had chemo so it isn’t a side effect of other medication.

I haven’t had any of these problems but have you tried biotin? I take 1000mg a day because my oncologist recommended it for hair growth and my nails and hair are doing wonderful.
