My doctor prescribed Wechol powder packets as an alternative Cholesterol lowering drug and the doctor faxed it into Medco. The prescription arrived in today's mail- $472.73 for a 90 day supply charged to our account. The Welchol tablets are 78.79, had I known the cost difference I would have not had the script filled or gone for the tables. Medco advised their minimum for notifiing a customer is $500.00, way too high in this economy. From now on I will go face to face with my pharmacy rather than the mail-in method. Cost of medication is outragious and Medco is not customer friendly.
