the larger issue is there should be no shortage of a simple generic used by a large number of people in the U.S. and people need to complain to their congress people.

and try to keep 1 months supply in reserve of your main pd drug and settle for a generic if you have to. global supply chains seem to be the norm and natural disasters more common. heck, if we had a cure this wouldn't matter. yet we spend how much on just slightly better pd drugs like azilect and can't get a generic drug that's been around for over 40 years? and then your chain pharmacy always goes for the cheapest generic since pharmacy benefit managers pay them so little over their cost, no incentives to make a better generic. talking only about the u.s.
