Brands of hormone therapy

Hi

can anyone help please?  I have been on Letrozole and  Zoladex since end of Feb and have recently been suffering considerably more with aches and pains in the last few weeks. Having read some of the posts I was wondering if the brand of Letrozole has been changed without me realising or should I be expecting this deterioration.  First of all how do I know what the brand is? It says the manufacturers are Novartis, distributed by Sandoz.  I haven’t kept any of my other boxes so not sure if they were the same or not.  Would the pharmacy be able to tell me if the brand has changed or as it says Letrozole does that mean it is the same? Feeling confused!

Thanks in advance

I have had four different brands and apparently unless your prescription is marked for a brand by doctor …you have to take pot luck!!
They all vary.
