Certain precautions that your physician would be taking care of are, using the lowest possible dose, for the shortest time, alternate day dosing can be followed if possible, and gradual withdrawal
to limit the adrenal suppression. Usually a treatment
for more than 3 weeks is taken as long term. I cannot advise the dose, which can cause neurological symptoms and side effects. Consult your physician for the needful in your case. Take care.
