I’m on it right now, and the benefits for me outweigh the horribleness. However, I know people who’ve been on high doses, or who are more sensitive, and get awful mood swings, brain fog, etc.
Prednisone is cheap (my copay for a 2 week supply was less than a dollar) and works beautifully.
It also has unpleasant side effects in the short term (upset stomach, mood swings, increased blood sugar, immunosuppression), and Very Nasty ones in the long term (ulcers, hyper tension, diabetes, cataracts, osteoporosis, suppression of your body’s ability to respond to any kind of illness / injury, weight gain, and many more).
Last time I was at a 60 mg a day taper (on at 60 mg for a day or two, then gradually decreasing 5-10 mg every day or two) I was also on a higher dose of an asthma med that irritates the stomach. Add to that: leftover pizza for breakfast, and 3 hours in waiting room hell with nary a bottle of antacids in sight… and I was unhappy.
A 40 mg taper (which is what I’m on now… for the second asthma flareup this year) has a really surreal side effect, one that I think NASA needs to try to harvest: localized increase in gravity. Pretty nifty, really, except it makes my body appear to weigh about 15% more than normal when I have to stand up and walk around.
Beyond that (since I’m on an acid suppressor anyway), I don’t have too much trouble with it except that sad feeling of the asthma trying to worsen as I taper off after having several days of really great breathing.
Anyway… I’m fortunate that I’ve never had to be on the stuff for more than 3ish weeks at a time. People who have to take it longer term really have to watch it - sometimes they have to bump their dose in case of illness, injury or surgery because it suppresses the body’s natural cortisol production. There are theories that John F. Kennedy would have died of his injuries even if they hadn’t been so grave, because he had damaged adrenal glands and no native cortisol production. A long-term prednisone user can take several years to taper off the filthy stuff.
