Medrol is marketed as Medrone in the UK. Generic equivalent of Medrol is Methylprednisolone.

    Medrol (Methylprednisolone) Dosage and Side Effects

    MEDROL is used in the treatment of various conditions such as allergy or inflammation; it can also be used to replace corticosteroid hormone when the body does not produce enough due to problems with the adrenal glands (e.g. adrenal insufficiency).
