Part of what may be missing was briefly touched upon upthread. Jails give out the meds they have, which are often the cheapest most accessible formularies. You can go in with long-standing records of use of say, amlodopine for high blood pressure, but all the jail has is Telmisarten. So you are now taking that and hoping for the best. Then you move to a new facility which may have what the jail gave you, or your previous prescription, or a third option, and there’s adjustment again.
I’m no doctor, nor do I have any knowledge of MIchael’s meds. But I do know that sometimes you’re stuck with what they have, and if you are dealing with adverse reactions, but there aren’t other options, quitting the meds can make a little sense in that regard.
