My mother has taken D/D before. It makes her angry, jittery, and sad. On Monday and Tuesday of this week, for a stereotactic radiosurgery, she had to take four four-MG doses over a period of eighteen hours. Only after this did I learn that the tapering off would take forty-six days. Even aside from my mother's problem with D/D, this strikes me as an absurdly long time.
It does seem like a long time but it's probably better to take the precaution. Dexamethasone is a very potent steroid and 16mg over 18 hours is a big dose, so just stopping this may cause steroid withdrawal symptoms.
