Aromasin and hair loss

[Bugaboo20]

I switched to Aromasin from Arimidex and my I began losing my hair immediately.  Changed back after 6 days but a week later, I'm still losing hair.  Any ideas on how long this will continue?

It gets rather difficult because not everyone will experience all or even any of the side effects and then IF one does the degree of effect may well differ from one person to the next. Most hair loss is reversible but there are some rare cases where re-growth is not complete. Regards ...

Hi Japdip,

Thanks for your reply.  Yes, it was approved by my doc.  The joint pain and hot flashes were much worse as well.  I'm getting handfuls of hair every day in the bathtub drain.  I am concerned that the hair loss is irreversible or may not grow back until I am finished with Arimidex.  What I have read is the jury is still out if it's permanent or not, and I haven't read anything about going from one AI to another.  I learned that Aromasin and Arimidex are quite different.  Aromasin permanently binds to the Aromatase and Arimidex is temporary.  I'll have to do more research about what that means chemically.

I would imagine that it would take quite a bit longer than only a week to see a difference. I'd give it at least a month and possibly a bit longer. You need to take into consideration the advantage of one drug over the other .... in some cases it may be worth the adverse effects. I suppose the switch back was fully approved by your Oncologist.   Regards ....
