My daughter has a history of chronic itp she was given a 10 mg dose of dexamethasone for 4 days, on day 3 still bleeding. How long do they take to kick in?

In brief: Call the doctor

First thing to do is call the doctor. Maybe the dose is not large enough to suppress the autoimmune process just yet or it might be a cumulative effect that will take time.
The Dexamethasone is in her system within 6 hours and has a long half life up to 54 hours.
