Letrozole side effects

Unsettled tummy can be a side effect. Hopefully it will improve.

No....just suddenly couldn't tolerate dairy. Took me ages to figure it out and i had testing to confirm. 

Thanks @primek maybe it is the lactose in the tablet?? It is awful

Not from the tablet but I developed lactose intolerance following chemo.
