Doxorubicin is used widely in the treatment of cancers, including breast,
ovarian, bladder and lung cancer, as well as non-Hodgkin's lymphoma,
Hodgkin's disease and sarcoma. Doxorubicin is the chemical name for
the drug. One of the most common brands of doxorubicin is
Adriamycin.
One way in which doxorubicin works is by binding to the cancer cells'
DNA (the genetic code) and blocking an important enzyme (called topo-isomerase
II). This causes the DNA to get tangled up and the cancer cells cannot
divide and grow.
Doxorubicin is a red liquid that you have as an injection into a vein (intravenously)
or as a drip (infusion) through a fine tube put into a vein (cannula).
Or you may have it through a central line.
Chemotherapy is usually given as a course of several cycles of treatment. The treatment
plan for doxorubicin depends on which cancer you are having treatment
for. To find out more about the way doctors plan chemotherapy treatment

Common Side Effects
Many people have one or more of the following side effects
-
Fatigue - patients say this is the most disruptive side effect of all. Tiredness
often carries on after treatment has ended. Most people find their energy
levels are back to normal from 6 months to a year after their treatment finishes.
-
Temporary effect on the bone marrow. The bone marrow makes blood cells and this can cause
-Drop in white blood cell count. This increases the risk of severe bacterial
infection. You may have headache, cough, sore throat, aches and pains,
fever, pain when passing urine or feel cold and shivery. Infections can
sometimes be life threatening. You should urgently contact a doctor if
you think you have an infection.
-Drop in red blood cell count (anaemia) - you may feel tired, look pale
or be short of breath. You may need a blood transfusion or treatment to
bring up your red cell count.
-Drop in platelets in the blood causing bleeding or bruising - you may
have bruises, a rash of red spots, bleeding gums or nosebleeds.
These effects on your bone marrow can begin about 7 days after each treatment
and usually return to normal at about 21-28 days. Your doctor will check
your blood counts regularly to see how well your bone marrow is working.
Contact your doctor if you have any of these side effects.
-
Feeling or being sick Doxorubicin can cause severe sickness. If you do get it, it may begin a few hours after treatment and last for
a few days. It is usually possible to control this side effect with anti-sickness
injections and tablets. If you are still being sick, tell your doctor or nurse.
-
Hair loss- Almost all people treated with doxorubicin have complete head and body
hair loss. It usually begins 2 - 5 weeks after the treatment starts. Remember
- this is only temporary. A cold cap may help to stop you losing your
hair, but you need to talk to your doctor about how advisable this is
with your type of cancer.
-
Sore mouth and throat. This can happen about 2-3 days after each treatment. You may have red
sore skin in your mouth and mouth ulcers. It usually clears up within
3 weeks of treatment.
-
Your urine may become a pink or red color for one or two days after treatment.
-
Black or brown discoloration may occur in the creases of your skin. This is particularly common in children.
-
Sensitivity to the sun. You should cover up and stay in the shade while you are having treatment
with this drug. If you must be exposed to the sun, use a high factor sun cream.
-
Watery eyes. This happens to about 1 in 4 people and may last for several days after
the beginning of each treatment. Very rarely, you may get sore eyes (conjunctivitis).
-
Your ability to become pregnant or father a child may be affected. It is important to talk to your doctor about your fertility before starting
treatment. Women may stop having periods (amenorrhoea). This may be temporary.
-
Doxorubicin may have a harmful effect on a developing baby. You should not become pregnant or father a child whilst taking this drug.

Occasional Side Effects of Doxorubicin
Some people have one or more of the following side effects
-
While you are having the chemotherapy infusion, doxorubicin may leak into the body tissues around the vein and cause a
sore to develop. It is important to tell the nurse or doctor if you have:
-Stinging or burning around the vein
-Leakage of fluid from the cannula site
-Red or swollen injection site after your treatment
-
Allergic reaction. 3 people in 100 have an allergic reaction to doxorubicin. You may experience
a sudden rash of pink, itchy bumps on your skin and a reddening of the
skin along the veins. This should clear up within a few days.
-
Radiation recall reaction.
Doxorubicin can affect areas of skin that have been treated with radiotherapy
in the past. These areas can become dry with flaking skin and you may
have some pain and burning similar to sun burn.
-
Heart damage. Doxorubicin can cause temporary damage to the muscles of the heart, which
may change the rhythm of the heartbeat. In most cases this will return
to normal after the treatment is completed. Your heart will be checked
before you start treatment.
-
Diarrhea - drink plenty of fluids and if it becomes severe or persistent tell your
doctor or nurse - you could become dehydrated.
- Loss of appetite
- Nails may become darker and white lines may appear on them
- Fever and chills
Side Effects with High Doses of Doxorubicin
With high doses of doxorubicin or many treatments with doxorubicin there
is a small risk that you may get
- Permanent damage to the heart
- Development of a second cancer
Remember
-
Not everyone will get these side effects. You may have none or several. A side effect may get worse through your
course of treatment, or more side effects may develop as the course goes
on. This depends on:
-How many times you've had the drug before
-Your general health
-How much of the drug you have (the dose)
-The way you take the drug (tablets or drip)
-Other drugs you are having
- Some side effects are upsetting or inconvenient, but not damaging to your health
-
Some side effects are serious medical conditions and need treating. Where we have urged you to contact your doctor, this is because:
-Your side effect may need treating
-Your drug dose may have to be lowered to try to prevent the side effect
-
Tell your doctor about any other medicines you are taking, including vitamins, herbal supplements and other over the counter remedies
- drugs can react together
-
Discuss side effects. Tell your doctor about your side effects so they can help you manage them
People you can talk to about your side effects: Your chemotherapy nurse,
clinic or ward nurse will have given you a contact number. You can ring
if you have any questions or problems. They can give you advice or reassure
you. If in doubt, call.
