Can the potent corticosteroid,budesodine cause rage and headaches? yes or no?

If you are taking Budesodine, this is a prodrug, specifically targeting the colon, and its mechanism avoids most systemic complications, by design. Thus, it would be highly improbable that this can be implicated as the main cause of your "rage and headaches". But do discuss this with the prescribing doctor.

It definitely can, notorious side effects for steroids in general. However, other reasons for above mentioned symptoms cannot be ruled out and discussing with current prescriber options at this point will be best.
