drug works" section below).
What this drug is used for:
- As an anti-inflammatory medication. Dexamethasone relieves inflammation in
various parts of the body. It is used specifically to decrease swelling (edema),
associated with tumors of the spine and brain, and to treat eye inflammation.
- To treat or prevent allergic reactions.
- As treatment of certain kinds of autoimmune diseases, skin conditions, asthma and

How this drug is given:
- This medication may be given to you in many forms. In a pill form, it is available
in a variety of tablet sizes. If you are on a daily dose of dexamethasone
(usually less than 10 mg), and you miss a dose, take the dose as soon as you remember.

Self Care Tips:
- If you are on this medication for a long period of time, you may be more susceptible
to infection. Wash your hands well, and report any symptoms of infection to your
healthcare provider if noted.
- If you are given eye drops or eye ointment: You may be more sensitive to the light.
Wearing sunglasses may help. It is normal to notice a little blurriness for a short
time after the drops or ointment are placed in your eyes. Notify your healthcare
provider with any changes in vision, blurriness, or eye pain.
- If you are given eye drops or eye ointment: Ask your healthcare provider if you
may wear contact lenses. Contact lenses may absorb the medication for at least 15
minutes. Wash your hands well before putting eye drops, to decrease the chance of
a bacterial infection in your eyes.

may need more frequent monitoring.
- Drink 2 to 3 quarts of fluid every 24 hours, unless you were told to restrict your

- Avoid sun exposure. Wear SPF 15 (or higher) sun block and protective clothing.
- To reduce nausea, take anti-nausea medications as prescribed by your doctor, and
eat small, frequent meals.
- In general, drinking alcoholic beverages should be avoided. You should also
limit caffeine intake (colas, tea, coffee and chocolate, especially). These beverages
may irritate your stomach.
- If you experience symptoms or side effects, especially if severe, be sure to discuss
them with your health care team. They can prescribe medications and/or offer
other suggestions that are effective in managing such problems.
Monitoring and testing:
You will be checked regularly by your health care professional while you are taking
dexamethasone, to monitor side effects and check your response to therapy.
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 effect 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).
