Periodic blood work to monitor your complete blood count (CBC) as well as the function
of other organs (such as your kidneys and liver) will also be ordered by your doctor.
How This Drug Works:
Corticosteroids are naturally produced by the adrenal gland in the body. Corticosteroids
influence the functioning of most of the body's systems (heart, immune, muscles
and bones, endocrine and nervous system). They exert a wide array of effects
including effects on the metabolism of carbohydrates, protein and fats. They
help to maintain balance of fluids and electrolytes.
Dexamethasone is classified as a corticosteroid (more precisely a glucocorticosteroid),
and has many uses in the treatment of cancer.
One way that it works is to decrease inflammation (swelling). It does this
by preventing infection- fighting white blood cells (polymorphonuclear leukocytes)
from traveling to the area of swelling in your body. (This is why you are more prone
to infection while taking steroids). Taking advantage of the anti-inflammatory
properties of the medication, corticosteroids are used to decrease the swelling
around tumors. For example, by decreasing swelling around tumors in the spine,
brain, or bone, it can decrease the pressure of the tumor on nerve endings and relieve
pain or other symptoms caused by the pressing tumor.
Another way this drug works is by altering the body's normal immune system responses.
Corticosteroids are used to treat certain conditions that affect the immune system
such as aplastic anemia (AA), Immune Thrombocytopenia Purpura (ITP), Thrombotic
Thrombocytopenia Purpura (TTP), or hemolytic anemia.
In addition, it is thought that corticosteroids may help in the treatment of patients
with blood disorders, such as multiple myeloma. Corticosteroids may work by causing
programmed cell death (apoptosis) of certain cells, which may help to fight your
Dexamethasone is also used in the short-term treatment of nausea caused by chemotherapy.
How it does this is not fully understood. It also has been used to stimulate
appetite for patients with severe appetite problems.
Corticosteroids are used to replace steroids in conditions of adrenal insufficiency
(low production of needed steroids produced by the adrenal glands).
