... that Humana will cover, because Humana will not cover the one my doctor wants me to take. I have Bronchitis and I am "coughing my head off"! Please help!!! My doctor prescribed Tessalon Perles 100 mg 45 quantity. I contacted Humana and they have NO idea of any cough medications in their formulary that they approve. I must have one that is a Rx, not over the counter. Humana just wants my doctor to keep calling in cough medicines until one will be approved. Really rotten. Any suggestions??
