... This is a new Costco policy as of June 3, 2013 requiring patients be seen every 3 months for Class 2 and every 6 months for Class 3 prescriptions. I have Adult ADHD and been on Adderall for 7 years and have seen the same Dr. for at least 20 years, I think he is capable of determining how often I should see him. I live in Idaho, do not have insurance and a medication visit is $175. I was told another pharmacy might fill it. Has anyone else had this problem?
