Sorry to hear your family member is struggling with getting medications. Are you based in the US? Purely anecdotal, but I work in an academic medical center and there have been no issues with steroid shortages. If your family member is having trouble to the point of not getting meds, if they live even remotely close to one, they (almost?) all have pharmacies that can fill scripts and I believe hydrocortisone can be prescribed for 90+ days at a time.

Less anecdotally, I’ve seen several COVID based guidelines recommending mail-order scripts — they are less geographically constrained, pretty much always on time and can be filled for similar timeframes, no standing in line etc.

Hope things get easier for your loved one!
