Hello - I was prescribed Letrozole in August 2017 following diagnosis for breast cancer. I took the Accord brand for 2 months which I got used to and eventually had minimal side effects. I then had repeat prescription and was given Cipla brand which I have been taking and am experiencing worse side effects including vision distortion (not good for driving), extreme fatigue and tiredness. So I've decided to stop taking them (only till I get new prescription) and have asked my doctor for repeat prescription to get the Accord brand. Its obvious from reading all the posts that different brands do seem to cause different side-effects depending on the individual. This has been an extremely helpful forum from my perspective and hope it helps others.
