Hypopituitary Support
Equivalent maximum doses (do not take pregnenolone
or any other adrenal supplement that breaks down
into cortisol with these)
cortisone acetate 37 1/2 (weak, not recommended)
hydrocortisone 30 mg
cortef 30 mg
prednisone 7 1/2 mg
prednisolone 7 1/2 mg
triamcinolone 6 mg
methylprednisolone 6 mg
**dexamethasone 1 mg
betamethasone 0.8 mg
*Isocort max dose 8 pellets-is said to have 2 1/2 mg of
cortisol per pellet, so 8 pellets is 20 mg of cortisol.
**info sources can range from
1 mg dex = 6 mg medrol = 30 mg Cortef
to
1 mg dex =16 mg medrol=80 mg Cortef.
In my experiance with dex (your experiance may differ),
I've found the equivalents to be closer to
1 mg dexamethasone=
40 mg Prednisone
32 mg Medrol
160 mg Cortef/HC.
***1 mg medrol =1/32 mg dexamethasone
***6 mg medrol = 6/32 mg dexamethsone
***Dexamethasone should not be used alone, but in
combination with Medrol no more than 50% dex/50% medrol.
