You’re joking about turning into a psycho killer queen, but that’s practically what happened to my mother (except for the killer part). Seriously.
A couple of years ago my mother, then in her late sixties, was given prednisone by the local hospital emergency room for some minor complaint. I forget what it was, and I don’t know the dose, but I’m sure it was only a single application, not a long course.
Within a day she became psychotic. At first she was only a little loopier than normal, but a few hours later she was manic, delusionary, wandering around outside (leaving her 90-year-old mother, then living with her, unattended) accosting strangers with wild stories and generally behaving like a crazy person.
I am not making this up.
We took her back to the emergency room, but they had no advice for what to do, other than just let it wear off. We kept an eye on her for the next several hours, tried to get her to sleep, or at least stay in her bedroom, and by the next morning she seemed to be more or less normal. So I left her (and my grandmother) and went home. But a few hours later she was as crazy as ever. I got a call that she had interrupted a meeting at her church with incomprehensible ranting.
It is now 48 hours since she took the prednisone, and she’s behaving as bizarrely as ever. She’s barely controllable, although fortunately for us, she’s a happy and pleasant psychotic, not violent or angry. Nevertheless, we are all naturally scared and very worried. It seems clear that the prednisone has caused it, but no one has any idea when, or even if, it will wear off.
Back to the emergency room and their only solution is to transfer her to a nearby psychiatric hospital. She stays there for about two weeks, during which she gradually comes down and begins to understand that this was a drug-induced psychotic incident, not some marvelous higher reality she’s discovered. Within a month she was essentially back to normal, and she’s been fine ever since.
The whole incident was easily the most traumatic thing that’s happened to my family in many years. So you can see why I don’t have pleasant associations with prednisone.
Obviously, this kind of experience is highly unusual, but steroids can have strange and unpredictable side effects.
