ITP: Idiopathic Thrombocytopenic Purpura

What is ITP?

Idiopathic Thrombocytopenic Purpura (ITP)
is a bleeding disorder. People with ITP can
bruise or bleed more easily than normal.
ITP is a disease of the blood in which the
body’s immune system attacks its own
platelets for unknown reasons. The immune
system attacks platelets by making proteins
(antibodies) which attach to these platelets.
They are then removed from the body by the
spleen. Normally, when you cut yourself,
your platelets rush to this wound and form a
clot to stop the bleeding. People with ITP
have fewer platelets to form a clot. This
causes you to bleed easier.

Types of ITP

There are two types of ITP: acute (short-
term) and chronic (long-term)
 Acute ITP most often lasts less than
6 months. It occurs mainly in
children after a viral illness. This
form of ITP often goes away within
a few weeks or months and may not
require any treatment.
 Chronic ITP may last 6 months or
longer, and it is the type of ITP that
most commonly affects adults.
Chronic ITP is 3 times more
common in women than men.
Treatment depends on bleeding
symptoms and your platelet count.
Mild cases without bleeding
symptoms may not require treatment.

Symptoms of ITP

When you have ITP, you may notice some
of these symptoms.
 Tiny, red or purple spots on the skin
or lining of your mouth (petechiae).
These are caused by bleeding from
small blood vessels under the skin.
 Painless, dime-sized bruises on the
skin or in the mouth (purpura)
 Nose bleeds
 Bleeding gums
 Heavy menstrual bleeding in women
 Blood in the urine or stool
 Bleeding in the brain. This is rare

Treatment for ITP

 Children: ITP often goes away on
its own within 6 months. Children
do not need treatment unless they
have a lot of bleeding or a very low
platelet count. Milder cases may
only need monitoring of symptoms
and blood work to check platelet
 Adults: ITP tends to remain in
adults, although the severity comes
and goes. Medicines and frequent
blood work are often needed.


Medicines Used to Treat ITP

 Steroids such as prednisone. They
help raise the platelet count in the
blood by slowing the activity of the
immune system. This medicine is
given by mouth.
 Immune globulin – given
 Anti-(Rh) D immunoglobulin –
given intravenously
 Rituxan® (Rituximab) – given
 Nplate® (Romiplostim) – given
 Promacta® (Eltrombopag)– tablet
given by mouth
 Other drugs that slow the activity of
the immune system may also be

Surgery: If the medicines do not work,
your doctor may remove your spleen. Since
the platelets get trapped in the spleen,
removing it helps to stop the breakdown. If
you have your spleen removed, you may be
more likely to get infections. Watch for
signs of infection such as fever. Get
treatment promptly.

Platelet transfusions may be needed by
people who have severe bleeding.

Caring for Yourself at Home

Talk with your doctor or nurse about what
activities are safe for you. Also talk about
when it is OK for you to return to work.
Avoid contact sports. Avoid injury that
could cause bruising or bleeding. Be careful
to avoid medicines such as aspirin and
ibuprofen. They can lower platelet counts
and cause bleeding. Be sure to tell your
doctor about all medicines that you are
taking, including supplements and over-the-
counter medications.

Be aware of the symptoms described above.
If you notice any of them, be sure to call
your doctor. If you have further questions
