the take away here is try to keep a month's supply of each medication if possible in reserve in case you get a less effective generic or there is a supply chain interruption. mfg's can get shutdown, natural disasters, contract disputes happen. seems with climate change there's a greater chance of not being able to easily get meds.

and call your pharmacy, insurance company and doctor the minute the problem arises, especially your insurance co., i assume they want you to be healthy and can contact their pharmacy benefits management company with your complaint.

i believe that to meet FDA requirements, generic mfg's just have to give their drug to healthy individuals after which drug blood levels are measured. doesn't mean they don't test on actual patients and/or animals and measure the affect, would be interesting to find out if they actually do.
