Find out about the side effects of the cancer drug combination CHOP.
Tell your doctor or nurse if you have any side effects so they can help you manage them. Your nurse will give you a contact number to ring if you have any questions or problems. If in doubt, call them.
The side effects may be different if you are having CHOP with other cancer treatments.
Common side effects
Each of these effects happens in more than 1 in 10 people (10%). You might have one or more of them.
Signs of an infection include headaches, aching muscles, a cough, a sore throat, pain passing urine, or feeling cold and shivery.
Cancer treatments can reduce the number of white blood cells in the blood. This increases your risk of infections. White blood cells help fight infections.
When the level is very low it is called neutropenia (pronounced new-troh-pee-nee-ah).
You have antibiotics if you develop an infection. You might have them as tablets or as injections into the bloodstream (intravenously). To have them into your bloodstream you need to go into hospital.
You might notice you:
- bruise more easily
- have nosebleeds
- have bleeding gums when you brush your teeth
This is due to a drop in the number of platelets that help clot your blood.
If your platelets get very low you may have lots of tiny red spots or bruises on your arms or legs called petechiae.
You'll have a platelet transfusion if your platelet count is very low. It is a drip of a clear fluid containing platelets. It takes about 15 to 30 minutes. The new platelets start to work right away.
This treatment makes the level of red blood cells fall (anaemia). You may feel breathless and look pale.
Red blood cells contain haemoglobin, which carries oxygen around the body. When the level of red blood cells is low you have less oxygen going to your cells.
You can also feel tired and depressed when your blood count is low and feel better once it is back to normal. The levels can rise and fall during your treatment. So it can feel like you are on an emotional and physical roller coaster.
You have regular blood tests to check your red blood cell levels. You might need a blood transfusion if the level is very low. After a transfusion, you will be less breathless and less pale.
Tell your doctor or nurse if you feel breathless.
You might feel very tired during your treatment. It might take 6 months to a year for your energy levels to get back to normal after the treatment ends. A low red blood cell count will also make you feel tired.
You can do things to help yourself, including some gentle exercise. It’s important not to push yourself too hard. Try to eat a well balanced diet.
Talk to your doctor or nurse if you are finding the tiredness difficult to manage.
You have regular blood and urine tests to check this. If you have diabetes you may need to check your blood sugar levels more often than usual.
Contact your doctor or pharmacist if you have indigestion or heartburn. They can prescribe medicines to help.
Skin changes include darker skin and rashes, which may be itchy.
Tell your doctor if you have any rashes or itching. Don't go swimming if you have a rash because the chlorine in the water can make it worse.
If your skin gets dry or itchy, smoothing in unperfumed moisturising cream may help. Check with your doctor or nurse before using any creams or lotions. Wear a high factor sun block if you’re going out in the sun.
You could lose all your hair or it may become thinner. This includes your eyelashes, eyebrows, underarm, leg and sometimes pubic hair. It usually starts gradually within 2 to 3 weeks after treatment starts.
Your hair will grow back once your treatment has finished. This can take several months and your hair is likely to be softer. It can also grow back a different colour or be curlier than before.
- Ask about getting a wig before you start treatment so you can match the colour and texture of your real hair.
- You could choose a wig for a whole new look.
- Think about having your hair cut short before your treatment starts.
- Some people shave their hair off completely so they don't have to cope with their hair falling out.
- Wear a hairnet at night so you won't wake up with hair all over your pillow.
Swelling in the face and body can be due to fluid build up. Let your doctor or nurse know if you have this.
Talk to your doctor or nurse if you’re having problems sleeping. It can help to change a few things about when and where you sleep.

- Make sure the temperature is right.
- Spend time relaxing before you go to bed - have a bath, read or listen to music.
- Do some light exercise each day to help tire yourself out.

Your mouth might become sore a few days after you start treatment. It usually clears up gradually 3 to 4 weeks after your treatment ends.
Your nurse can give you mouthwashes to help prevent infection. You have to use these regularly to get the most protection.
Tell your doctor or nurse straight away if your mouth is really sore. They can help to reduce the discomfort. Some people need strong painkillers to help control mouth pain so they can eat and drink.
- Clean your mouth and teeth gently, use a soft bristled toothbrush.
- Avoid mouthwashes that contain alcohol.
- Use dental floss daily but be gentle so that you don't harm your gums, and don't floss if you have very low platelets.
- Avoid neat spirits, tobacco, hot spices, garlic, onion, vinegar and salty food.
- Moisten meals with gravies and sauces to make swallowing easier.
- Eating fresh or tinned pineapple can keep your mouth fresh and moist.

You might lose your appetite for various reasons when you are having cancer treatment. Sickness, taste changes or tiredness can all put you off food and drinks.
- Eating several small meals and snacks throughout the day can be easier to manage.

Mood changes can include feeling very sad and depressed. Tell your doctor or nurse if you’re feeling depressed. They can arrange for you to talk to someone and give treatment if necessary.
This is caused by the doxorubicin. It won't harm you.
Tell your doctor or nurse if you have diarrhoea. They can prescribe medicine to help you.
Drink at least 2.5 litres of fluid a day. This helps to keep you hydrated.
