Hi I contact the nurse re side effects from Letrozole. The nurse was so knowledgeable & supportive & gave me expert advice. I was experiencing severe diarrhoea & muscle/joint pain . nauseau & headache. i stopped the medication & in a week i have had no further diarrhoea (Best result) , the pain continous but i think the half life of the meds is about 4 weeks. ive since spoken to my consultant & he agrees i should stay off it for 6 weeks .They will then review me & change the meds. 

I cant thank the nurse enough & this forum is so helpful. Thank you
