My daughter was on Entocort - Budesonide - for over a year. She had also been on Prednisone on and off for the previous 5 years. She developed Cushing's syndrome and adrenal insufficiency while on Entocort.
Cushing's syndrome means the puffy round steroid face, stretch marks, rapid weight gain.
As a 20 year old, you can imagine, she was NOT happy. There is nothing you can do about Cushing's syndrome except stop using steroids and wait for it to go away. It has been almost a year now and she still has the puffy round face and hasn't lost the steroid weight, despite trying very hard.
Then on top of that, she developed adrenal insufficiency. Your adrenal glands get so used to getting cortisol from an outside source that they stop producing it. They "go to sleep" as her endocrinologist explained it. They also do not produce any cortisol to compensate for any additional stresses on the body. For example, if you had a cold and a fever, normally your adrenal glands would produce extra cortisol. If you have adrenal insufficiency, they don't and you can go into adrenal crisis, which can be fatal.
Because of the adrenal insufficiency, she has to take hydrocortisone daily until her adrenal glands start functioning. If her body is under any stress - an illness, a procedure with sedation for example - we have to give her a stress dose, or she could go into adrenal crisis.
In addition to these side effects, low bone density, diabetes, glaucoma and increased risk of infection are common issues with long term steroids.
We never viewed Budesonide as a real steroid - we thought it was not as bad as Pred, and it isn't. But it still is a steroid and in the long-term, it can cause all these side effects. Her endocrinologist certainly counts it as a steroid and says it should be used for the shortest time possible.
If you had side effects with Humira, I would look at other biologics - there is Remicade, Cimzia, Entyvio, Stelara.
MTX is also an option and would work for the psoriasis.
Steroids should not be used as maintenance drugs.
