Thank you for the thread link! I’ve been told by my MO that I will start anastrozole after I finish radiation at the end of February. I am lactose-sensitive and gluten-free, so have been doing a lactose-free/gluten-free for the last year which as dramatically decreased my arthritis symptoms. I now see that anastrozole has 65 mg of lactose in it, and letrozole has 45 mg! I do think these 2 AI’s have the best impact on invasive lobular (ILC) so I’m really torn. Anyone who is lactose-free taking anastrozole? Help!
