Good idea to stock up, but impracticable. I called my pharmacy (CVS) this morning to renew my regular Rx. The normal renewal date is next Wednesday; CVS will allow a refill no more than 3 days before the 30-day period, so I can't pick it up until tomorrow. That's OK. I have enough for my Monday injection. I asked the reason for the restriction: because it's a controlled substance, they are allowed to renew no more than 3 days early. I don't know whether that's an internal CVS restriction or whether it's from the DEA. But that seems to negate the ability to get a 60- or 90- day prescription. Besides, that merely kicks the can down the road.
