I am an oncologist in a case as a legal expert where a patient claims that her sensory-peripheral neuropathy was caused by Tamoxifen. By pharmacist error in dispensing the drug properly, she took 40mg of tamoxifen daily. She is claiming legally her oncologist because she is disabled secondary to her action. Please give me an advice. I did'nt find evidence in the medical literature except for optic neuropathy secondary to Tamoxifen and excellent response of POEMS to tamoxifen therapy.
