I've been on a low dosage of pain medications post-surgery for bone cancer. I have one local doctor who prescribes them my insurance and doctor allows me to fill them a few days early for convenience.
This month I was informed they won't fill it until the 31st day. This is an annoyance, but my real complaint is the lack of uniform enforcement. The policy disproportionately effects people with chronic pain and mental disabilities, since they find it suspicious that people are on the same meds for years. Either fill every prescription on the 31st day, or fill them when insurance and doctors allow.
Pharmacists are not real doctors, and I find it offensive that they are making these decisions. The effect on people with disabilities makes this a possible ADA issue.
