1. OPtum rx sent notice in December re: my mother's RX for Ranitidine = can cause cancer. Stop taking. I called OPtum & they refuse to provide coverage for the replacement drug Famotidine. I called our MD who states they called in a replacement. Optum states they never recived the request for a new Rx and still refuses to cover the Famoditinde. 2. Optum Rx sent me an email stating they could not complete order for another rx - her Pravastatin & to call them immediately. When I called after speaking to a customer service rep who was not helpfuyl - I was told that they had already mailed the Pravastatin. Could not give me an explanation as to why I was sent the email at 8:22 this morning. I have no idea what to expect at this point.
