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).

Pregnancy and breast feeding:
You must tell your doctor if you are pregnant, think you might be pregnant or are trying to become pregnant as this medicine could slow the baby’s growth.
You should tell your doctor if you are breast feeding as small amounts of corticosteroid medicines may get into breast milk.
Corticosteroids can affect growth in children.
Like all medicines, MEDROL can have side effects although not everybody gets them.
