This medication is used to treat anemia (low red blood
cell count) in people with long-term serious kidney disease (chronic kidney
failure), people receiving zidovudine to treat HIV, and people receiving
chemotherapy for some types of cancer (cancer that does not involve the
bone marrow or blood cells). It may also be used in anemic patients to
reduce the need for blood transfusions before certain planned surgeries
that have a high risk of blood loss (usually given with an
anticoagulant/"blood thinner" medication such as warfarin to lower the risk
of serious blood clots). Epoetin alfa works by signaling the bone marrow to
make more red blood cells. This medication is very similar to the natural
substance in your body (erythropoietin) that prevents
anemia.
This monograph is about the following epoetin alfa
products: epoetin alfa and epoetin alfa-epbx.
Read the Medication Guide and, if available, the
Instructions for Use provided by your pharmacist before you start using
this medication and each time you get a refill. If you have any questions,
ask your doctor or pharmacist.
This medication is given as an injection under the skin
or into a vein as directed by your doctor, usually 1 to 3 times a week.
Patients getting this medication before surgery may have a special dosing
schedule. Hemodialysis patients should receive this medication by injection
into a vein. If injecting this medication under the skin, the injection is
given in the upper arms, abdomen, front of the middle thighs, or upper
outer area of the buttocks. The dosage is based on your medical condition,
weight, labs, and response to treatment.
If you are using this medication at home, learn all
preparation and usage instructions from your health care professional. Do
not shake this medication. Before using, check this product for particles
or discoloration. If either is present, do not use the liquid. If you are
injecting this medication under the skin, before each dose, clean the skin
you are going to inject into (the injection site) with rubbing alcohol.
Change the injection site each time to lessen injury under the skin. Do not
inject into skin that is tender, red, bruised, hard, or has scars or
stretch marks. To lessen bruising, do not rub the injection site after a
shot. Learn how to store and discard medical supplies
safely.
Use this medication regularly to get the most benefit
from it. To help you remember, use it on the same day(s) of the week as
directed.
Do not increase your dose or use this drug more often or
for longer than prescribed. Your condition will not improve any faster, and
your risk of side effects will increase.
It may take 2 to 6 weeks before your red blood cell
count increases. Tell your doctor if your symptoms do not get better or if
they get worse.
Headache, body aches, cough, or injection site
irritation/pain may occur. If any of these effects last or get worse, tell
your doctor or pharmacist promptly.
Remember that this medication has been prescribed
because your doctor has judged that the benefit to you is greater than the
risk of side effects. Many people using this medication do not have serious
side effects.
Epoetin alfa may sometimes cause or worsen high blood
pressure, especially in patients with long-term kidney failure. This effect
may be caused by the number of red blood cells increasing too quickly,
usually within the first 3 months of starting treatment. If you have high
blood pressure, it should be well controlled before beginning treatment
with this medication. Your blood pressure should be checked often. Ask your
doctor if you should learn how to check your own blood pressure. If high
blood pressure develops or worsens, follow your doctor's instructions about
diet changes and starting or adjusting your high blood pressure medication.
Lowering high blood pressure helps prevent strokes, heart attacks, and
further kidney problems. Keep all lab appointments to have your red blood
cell count/hemoglobin level tested regularly to reduce the chance of this
side effect.
Rarely, this medication may suddenly stop working well
after a period of time because your body may make antibodies to it. A very
serious anemia can result. Tell your doctor right away if symptoms of
anemia return (such as increased tiredness, low energy, pale skin color,
shortness of breath).
Tell your doctor right away if you have any serious side
effects, including:
- symptoms of heart failure (such as shortness of breath,
swelling ankles/feet, unusual tiredness, unusual/sudden weight
gain)
Get medical help right away if you have any very serious
side effects, including:
This medication may rarely cause serious (sometimes
fatal) problems from blood clots (such as heart attack, stroke, blood clots
in the lungs or legs). You may be at increased risk for blood clots if you
are severely dehydrated, or have a history of blood clots, heart/blood
vessel disease, heart failure, stroke, pregnant, or if you are immobile
(such as on very long plane flights or being bedridden). If you use
estrogen-containing products, these may also increase your risk. Before
using this medication, if you have any of these conditions report them to
your doctor or pharmacist. Get medical help right away if any of these side
effects occur:
- shortness of breath/rapid breathing
- chest/jaw/left arm pain
- unusual sweating
- confusion
- sudden dizziness/fainting
- pain/swelling/warmth in the groin/calf
- sudden/severe headaches
- trouble speaking
- weakness on one side of the body
- sudden vision changes
- blood clots in your hemodialysis vascular access site
A very serious allergic reaction to this drug is rare.
However, get medical help right away if you notice any symptoms of a
serious allergic reaction, including:
- rash
- itching/swelling (especially of the face/tongue/throat)
- severe dizziness
- trouble breathing
