Breast cancer survivor on femara for 6 months having brain fog, joint pain and eye issues. pycogenol was suggested as a supplement. it does seem to be helping. will it cause the femara to not work or increase the possibility of bc recurrance?

Since pycogenol is a supplement and not investigated by the FDA many physicians will not endorse its use for fear of contaminants that could interfere with medications or have potentially harmful health effects or have confidence in its claims of efficacy or recommended dose. Your pharmacist may be able to provide you with more information on this supplement.
