Living Alone With Addison's Disease: When Self-Injection Training Isn't Enough on Its Own
A single patient whose recent illness was managed correctly, but whose living situation exposes a real, documented gap between being trained to self-inject and being able to when a true crisis hits.
Felix A., a 34-year-old software developer, moved into his own apartment eight months ago after his diagnosis with autoimmune Addison's disease and a breakup that happened, he says, entirely coincidentally around the same time. He works fully remote, which means the person most likely to notice if something went badly wrong on an ordinary Tuesday is nobody at all until a video call goes unanswered. He was prescribed an emergency hydrocortisone injection kit at diagnosis and completed a single in-clinic training session, but has never had to use it, and admits he has not looked at the instruction sheet since. Today's visit was prompted by a mild stomach virus last week that left him vomiting twice — he managed it correctly with oral sick-day dosing and never came close to needing the injection — but it is the closest call he has had, and it is what brought the actual injection kit, sitting unopened in his bathroom cabinet, into today's conversation.
Llahana et al.'s 2025 mixed-methods survey of 688 patients and caregivers found that although over 60% had at some point needed parenteral hydrocortisone for a genuine crisis, fewer than 20% managed to self-inject when the moment actually came — and that the multi-step preparation of the injection itself was named as a barrier by 81% of them. Hover et al.'s 2025 survey, run through the National Adrenal Diseases Foundation and asking only about events that had actually reached crisis, found 41% unable to self-administer, citing the confusion and physical impairment the crisis itself produces as the main reason, not lack of willingness or training; a failed injection was followed by a materially worse outcome about a third of the time. Across this literature the shape is consistent: most patients are trained and hold a kit, and well under a quarter succeed in using it when a crisis actually arrives. Felix lives precisely inside the scenario those numbers describe most starkly — alone, with nobody nearby trained to help if he were the one who became too confused to act, and a kit that has sat in a bathroom cabinet, unopened, since the day he was handed it.
Follow-up visit, reviewing the emergency kit
What actually happened last week is encouraging — he recognized the illness, doubled his oral dose correctly, and never needed the injection. I'd use today's visit to refresh his own self-injection training while that success is fresh, rather than assume he can't act if the moment ever demands it.
I don't doubt that he handled the illness well — that's the part sick-day rules are designed for, and they worked. A true adrenal crisis is a different event; Hover et al. surveyed patients who had actually reached that point and found 41% unable to self-inject, and the reason wasn't lack of training, it was the crisis itself causing the confusion and physical impairment that made self-administration unreliable. Llahana's group found the same gap from the other end — over 60% had needed the injection, under 20% got it into themselves. We can't plan around Felix being the one who saves himself if the literature says that specific step fails on close to half the people who try it.
I'm not saying skip his training — he should absolutely know how to use it — I'm saying it can't be the whole plan for someone who lives entirely alone.
And that's exactly his situation — no household member to train as backup, parents out of state. So the plan has to be built from what he actually has: a medical alert bracelet so that whoever finds him, even a stranger or EMS, knows to give hydrocortisone immediately without waiting on a workup; his address and diagnosis on file with local EMS dispatch; and a daily check-in habit with a neighbor or friend, low-effort enough that he'll actually keep doing it. None of these alone is reliable. Together, they cover the gap a self-injection-only plan leaves wide open for him specifically.
Agreed: refresh his self-injection training today, order a medical alert bracelet, and coordinate pre-notification with local EMS given his address and diagnosis. A daily check-in habit was discussed and Felix committed to setting one up with a neighbor this week, in whatever form he'll actually sustain.
The team's actual medical plan was agreed without residual disagreement. The one open thread — whether Felix might eventually relocate closer to family — came up only as a personal aside the emergency medicine physician raised in passing; Felix himself didn't treat it as a live question, and the team agreed it falls outside a medical recommendation regardless.
