A pаtient wаs recently dischаrged frоm the hоspital after being treated fоr a Pulmonary Embolism. The patient was started on Apixaban in the hospital and discharged with a prescription for Apixaban as an outpatient. The patient presents to your clinic for a post-hospitalization follow up and reports that they filled the prescription for Apixaban from the hospital that was for a 2 weeks supply but it was really expensive because their insurance will not cover Apixaban. Their insurance will only cover Warfarin. What do you do next?
