I’m not sure what state you live in, but typically the first fill or two are one week “trial periods.” If you need it after that, typically they cover it 30 days at a time. Cor CII controlled substances, 30 days is max. I’m having this problem with one of mine, as it’s on backorder. Joy.
Prior authorizations might be necessary in that case. I also don’t trust mail order; stuff gets stolen that way.
Yes, for me the first four seven-day fills were the trial, and were allowed to be filled at a local pharmacy. After that they force us to use mail order for “maintenance” meds. And it was another three months of seven-day mail-order fills, each one notated that it was pending prior auth. I called them several times early on, but it was clear they were going to just pull my chain, so I just kept up with the weekly order.
