Carboplatin and etoposide are chemotherapy drugs you have together.
You pronounce carboplatin as car-bo-pla-tin. You pronounce etoposide as ee-top-o-side.
You might have them as a treatment for a number of different cancer types.
How does carboplatin and etoposide work?
These chemotherapy drugs destroy quickly dividing cells, such as cancer cells.
How do you have carboplatin and etoposide?
You usually have carboplatin and etoposide into your bloodstream (intravenously).
You might also have etoposide as capsules. They are pink in colour. You take them on an empty stomach with a glass of water.
Into your bloodstream
You might have treatment through a long plastic tube that goes into a large vein in your chest. The tube stays in place throughout the course of treatment. This can be a:
- central line
- PICC line
- portacath
Taking your capsules
Whether you have a full or empty stomach can affect how much of a drug gets into your bloodstream.
You should take the right dose, not more or less.
Talk to your healthcare team before you stop taking or miss a dose of a cancer drug.
Talk to your specialist or advice line before you stop taking a cancer drug.
How often do you have carboplatin and etoposide?
You have carboplatin and etoposide as cycles of treatment. This means that you have the drugs and then a rest to allow your body to recover. Each cycle of treatment lasts 3 weeks (21 days).
Depending on your cancer type you may have between 4 and 6 cycles.
This is one way of having carboplatin and etoposide:
- you have carboplatin as a drip over 1 hour
- you have etoposide as a drip over 1 hour
- you have etoposide as a drip over 1 hour
- OR
- you take etoposide capsules
- You have no treatment
You then start a new cycle of treatment.
Some hospitals may also give you G-CSF to take. This is an injection under your skin and helps the body produce white blood cells to reduce the risk of infection.
Tests
You have blood tests before and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
What are the side effects of carboplatin and etoposide?
How often and how severe the side effects are can vary from person to person. They also depend on what other treatments you're having.
When to contact your team
Your doctor, nurse or pharmacist will go through the possible side effects. They will monitor you during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:
- you have severe side effects
- your side effects aren’t getting any better
- your side effects are getting worse
Early treatment can help manage side effects better.
We haven't listed all the side effects here. Remember it is very unlikely that you will have all of these side effects. But you might have some of them at the same time.
Common side effects
These side effects happen in more than 10 in 100 (more than 10%). You might have one or more of them. They include:
Increased risk of infection
Increased risk of getting an infection
is due to a drop in white blood cells. Symptoms include a change in temperature, aching muscles, headaches, feeling cold and shivery and generally unwell. You might have other symptoms depending on where the infection is.Infections can sometimes be life threatening. You should contact your advice line urgently if you think you have an infection.
Bruising, bleeding gums or nose bleeds
This is due to a
drop in the number of platelets in your blood
. These blood cells help the blood to clot when we cut ourselves. You may have nosebleeds or bleeding gums after brushing your teeth. Or you may have lots of tiny red spots or bruises on your arms or legs (known as petechiae).Less commonly you might bleed from other areas of the body. Tell your medical team if you notice any bleeding.
Feeling or being sick
Feeling or being sick
is usually well controlled with anti sickness medicines. Avoiding fatty or fried foods, try eating small meals and snacks, drinking plenty of water, and relaxation techniques can all help.It is important to take anti sickness medicines as prescribed even if you don’t feel sick. It is easier to prevent sickness rather than treat it once it has started.
Tummy (abdominal) pain
Tell your doctor or nurse if you have this. They can check for the cause of the pain and give you medicine to help.
Loss of appetite
You might
lose your appetite
for various reasons while having cancer treatment. Sickness, taste changes or tiredness can put you off food and drinks.Feeling generally unwell

Changes in the levels of minerals, proteins and enzymes in your body
Your blood contains different levels of minerals, proteins and enzymes. This treatment can change the levels of calcium, phosphate, magnesium, sodium, potassium, creatinine, and urea in your blood.
You have regular blood tests to check for any changes in these levels.

You might have
liver changes
that are usually mild and unlikely to cause symptoms. They usually go back to normal when treatment finishes. You have regular blood tests to check for any changes in the way your liver is working.Skin changes

What else do you need to know?
Other medicines, foods and drinks
Cancer drugs can interact with medicines, herbal products, and some food and drinks. We are unable to list all the possible interactions that may happen. An example is grapefruit or grapefruit juice which can increase the side effects of certain drugs.
Tell your healthcare team about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies. Also let them know about any other medical conditions or allergies you may have.
Pregnancy and contraception
This treatment may harm a baby developing in the womb. It is important not to become pregnant or father a child while you are having treatment and for at least 6 months afterwards.
Women must use reliable contraception during treatment. Men must use reliable contraception during treatment and for at least 6 months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.
Loss of fertility
You may not be able to become pregnant or get someone pregnant after treatment with these drugs. Talk to your doctor before starting treatment if you think you may want to have a baby in the future.
Men might be able to store sperm before starting treatment. And women might be able to store eggs or ovarian tissue. But these services are not available in every hospital, so you would need to ask your doctor about this.
Breastfeeding
Don’t breastfeed during this treatment. This is because the drugs may come through in your breast milk.
Treatment for other conditions
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment. For example, if you need treatment for anything else, including teeth problems.
Immunisations
Don’t have immunisations with live vaccines while you’re having treatment and for up to 12 months afterwards. The length of time depends on the treatment you are having. Ask your doctor or pharmacist how long you should avoid live vaccinations.
In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and one of the shingles vaccines called Zostavax.
You can have:
- other vaccines, but they might not give you as much protection as usual
- the flu vaccine (as an injection)
- the coronavirus (COVID-19) vaccine - talk to your doctor or pharmacist about the best time to have it in relation to your cancer treatment
Members of your household who are aged 5 years or over are also able to have the COVID-19 vaccine. This is to help lower your risk of getting COVID-19 while having cancer treatment and until your
recovers from treatment.
Contact with others who have had immunisations - You can be in contact with other people who have had live vaccines as injections. Avoid close contact with people who have recently had live vaccines taken by mouth (oral vaccines) such as the oral typhoid vaccine. Sometimes people who have had the live shingles vaccine can get a shingles type rash. If this happens they should keep the area covered.
If your immune system is severely weakened, you should avoid contact with children who have had the flu vaccine as a nasal spray as this is a live vaccine. This is for 2 weeks following their vaccination.
Babies have the live rotavirus vaccine. The virus is in the baby’s poo for about 2 weeks and could make you ill if your immunity is low. Get someone else to change their nappies during this time if you can. If this isn't possible, wash your hands well after changing their nappy.
