Steroid Conversion Calculator
Can be used to convert between corticosteroid medication dosages for oral and IV administration.
In the text below the tool you can find out more about the substances that are available to be converted.
In practice, steroids may have to be administered alternatively or substituted for oral and IV administration.
The steroid conversion calculator performs the equivalence for any given dose for all the steroids available in the drop down lists.
This is the complete list of the steroids that can be used in the convertor:

The steroid convertor transforms one steroid dosage into another dosage based on the equivalent dose for either IV or oral administration.
The following table offers information on the equivalent dose, the anti-inflammatory and mineralocorticoid potency and about biological half-life.
|Compound||Equiv. dose||Anti inflammatory potency||Mineralocorticoid potency||Half-life*|
When dosing, you also need to consider the potency and the duration of the effect not only the steroid conversion in mg. For example, drugs such as Dexamethasone have a very long half life, therefore do not require frequent dosing.
*Biological half life accurately reflects the action duration of corticosteroid medication. The following legend has been used in the table:
■ Short = 8 – 12 hours;
■ Intermediate = 12 – 36 hours;
■ Long = 36 – 72 hours.
Cortisone – also known as corticosteroid, suppresses inflammation in conditions such as arthritis, lupus, ulcerative colitis etc.
Hydrocortisone – is a topical corticosteroid that reduces redness and itching in skin conditions.
Prednisone – is an anti-inflammatory that suppresses the immune system, it is used to treat allergic disorders, skin conditions, arthritis etc.
Prednisolone – is the active metabolite of prednisone, it is used as a prednisone replacement in the above specified conditions, in patients with liver failure.
Triamcinolone – relieves inflammation in various skin conditions.
Methylprednisolone – used in conditions that respond to corticosteroids like the ones above but also in conditions affecting the nervous system, blood cells and lungs.
Betamethasone – used to treat rheumatic disorders, dermatitis, asthma, Crohn disease, and in adrenocortical insufficiency.
Dexamethasone – is used as inflammatory but also along antibiotics in tuberculosis treatment.
