Possible Chemotherapy Side Effects
Your nurse will go over this information with you and tell you which side effects you may have. You may have some, all, or none of these side effects.
Fatigue is feeling unusually tired, weak, and like you have no energy. Fatigue from chemotherapy treatment can range from feeling a little tired to feeling extremely tired. Fatigue can start quickly or grow slowly over time.
How to manage fatigue
- If you feel tired, take a rest break. You can take short naps about 15 to 20 minutes long. Taking shorter naps will help with your fatigue throughout the day. Taking shorter naps will also help you sleep better at night.
- Try to be active to keep your energy levels up. For example, go for a walk outside or on a treadmill. People who do light exercise, such as walking, may have less fatigue and handle chemotherapy treatment better. Read Managing Cancer-Related Fatigue with Exercise to learn more.
- Plan tasks or activities on days and during times where you know you’ll have more energy.
- Don’t be afraid to ask for help. Ask your family and friends for help with tasks or activities that make you feel tired.
-
Drink enough liquids. Drink 8 to 10 (8-ounce) glasses of non-caffeinated liquids every day. Examples include:
- Water.
- Juices diluted (mixed) with water.
- Liquids with electrolytes, such as Pedialyte®, Gatorade®, Powerade®, and other sports drinks.

Nausea, vomiting, or loss of appetite
Some chemotherapy can cause nausea (feeling like you’re going to throw up) and vomiting (throwing up). This is because chemotherapy irritates the areas of your brain that control nausea or the cells lining your mouth, throat, stomach, and intestines.
How to manage nausea, vomiting, or loss of appetite
- Take your anti-nausea medicine as instructed by your healthcare provider.
-
Drink 8 to 10 (8-ounce) glasses of liquids every day so you don’t get dehydrated (losing more fluid from your body than usual). Examples include:
- Water.
- Juices diluted (mixed) with water.
- Liquids with electrolytes, such as Pedialyte®, Gatorade®, Powerade®, and other sports drinks.
- Don’t drink anything that has caffeine, such as coffee, tea, and soda.
- Eat small meals often. Do this throughout the day while you’re awake.
- Don’t eat greasy foods, such as fried foods.
- Get acupressure treatment. Acupressure is an ancient healing art that’s based on the traditional Chinese medicine practice of acupuncture. With acupressure, you put pressure on specific places on your body. Read Acupressure for Nausea and Vomiting to learn more.
When to call your healthcare provider for nausea, vomiting, or loss of appetite
Call your healthcare provider if you:
- Vomit 3 to 5 times within 24 hours.
- Have nausea that doesn’t get better after you take your anti-nausea medicine.

Constipation
Constipation is having 1 or all 3 of these:
- Fewer bowel movements than what’s normal for you.
- Hard bowel movements.
- A hard time passing bowel movements.
It’s a common side effect of medicine used to treat pain and nausea. Some chemotherapy can also cause constipation.
How to manage constipation

- Drink at least 8 (8-ounce) glasses of liquids every day, if you can.
- Go for a walk or do light exercises, if you can.
-
If needed, take an over-the-counter medicine (medicine you buy without a prescription) to treat your constipation. Your healthcare provider will tell you how much of these medicines you should take. Examples include:
- Stool softeners, such as Colace®, which make your bowel movements softer and easier to pass.
- Laxatives, such as Senokot® or MiraLAX®, which help you have a bowel movement.
When to call your healthcare provider for constipation
Call your healthcare provider if you:

Some chemotherapy can cause mucositis (myoo-koh-SY-tis). Mucositis is redness, swelling, tenderness, or sores in your mouth, or on your tongue or lips. Symptoms can start 3 to 10 days after your first chemotherapy treatment.
How to manage mucositis
-
Rinse your mouth every 4 to 6 hours, or more often as needed. Use an alcohol-free mouthwash or make your own solution. To make your own solution, mix 1 to 2 teaspoons of salt with 1 quart (4 cups) of water.
- Swish the mouthwash or solution in your mouth. Gargle well for 15 to 30 seconds. Then spit it out. Don’t swallow it.
- Don’t use a mouthwash that contains alcohol or hydrogen peroxide. These can make your sores worse. Use a mouthwash with no alcohol or sugar, such as Biotène® Dry Mouth Oral Rinse.
- Use a soft toothbrush for your teeth and gums.
- Don’t eat acidic (sour), salty, or spicy foods.
- Don’t smoke or use tobacco products.
- Don’t eat foods that are hot to touch.

Weakened immune system
A weakened immune system can be caused by neutropenia (new-tro-PEE-nia). Neutropenia is when you have a low number of neutrophils (NEW-tro-fills) in your blood. Neutrophils are a type of white blood cell that helps your body fight infections. Neutropenia is often caused by chemotherapy.
When you have neutropenia, you’re at greater risk for infection. The following instructions will help to keep you from getting an infection. Follow these instructions until your neutrophil count (the number of neutrophils in your blood) returns to normal.
How to manage a weakened immune system
- Don’t be near people who are sick.
- Wash your hands with soap and water for at least 20 to 30 seconds.
- Cover all parts of your hands with an alcohol-based hand sanitizer. Rub your hands together for 20 to 30 seconds, or until they’re dry.
-
Remember to always clean your hands:
- Before eating a meal.
- After touching something that may have germs. Clean your hands after using the bathroom, touching a doorknob, or shaking hands.
- Shower with a 4% chlorhexidine gluconate (CHG) solution antiseptic skin cleaner, such as Hibiclens®. Follow your healthcare provider’s instructions.
When to call your healthcare provider for a weakened immune system
Call your healthcare provider if you:
- Have a fever of 100.4° F (38° C) or higher.
- Are shaking or have chills.
-
Start to get other signs or symptoms of infection, such as:

Increased risk of bleeding
After your chemotherapy treatment, you may have a low platelet count (the number of platelets in your blood) for 10 to 14 days. A low platelet count lowers your body’s ability to stop bleeding or bruising.
How to manage increased risk of bleeding
- Use a soft toothbrush for your teeth and gums.
-
Be careful not to:
- Get any cuts, scratches, or scrapes.
- Bump into things or hit things by accident.
- Trip and fall.
- If you need to shave, use only an electric razor.
- Don’t do activities that can result in injury.
-
Don’t use:
- Rectal suppositories (solid medicine that’s inserted through your anus and dissolves).
- Enemas (liquid you put into your rectum through your anus to cause a bowel movement).
When to call your healthcare provider for increased risk of bleeding
Call your healthcare provider if you have:
- Blood in your urine (pee), bowel movements (poop), vomit (throw up), or when you cough.
- Very dark or black bowel movements.
- Unexplained (unusual) bruising or bleeding from your nose or gums.
- Changes in your vision.
- Very bad headaches or any signs of a stroke, such as weakness on one side of your body.

Hair thinning or hair loss
Some chemotherapy can cause hair loss. Hair loss usually starts about 2 to 4 weeks after your first chemotherapy treatment. If you lose your hair, it will begin to grow back a few months after your last treatment. Your hair may grow back as a different color or texture.
How to manage hair thinning or hair loss
- If your hair is long, you may want to cut it short before you begin treatment.
- Wash and condition your hair every 2 to 4 days. Use a baby shampoo or other mild shampoo, and a cream rinse or hair conditioner.
- Use shampoos and conditioners that have sunscreen in them. This will help prevent sun damage to your scalp.
- Don’t expose your scalp to the sun. Keep your head covered in the summer.
- In the winter, cover your head with a hat, scarf, turban, or wig to keep it warm. This can also help to contain hair that falls out.
- Sleep on a satin or silk pillowcase. These are smoother than other fabrics and can reduce hair tangles.
- Ask your healthcare provider if scalp cooling treatment (using a cold cap) is an option for you. Read Managing Hair Loss with Scalp Cooling During Chemotherapy for Solid Tumors to learn more.

Neuropathy (numbness or tingling in hands and feet)
Some chemotherapy can affect the nerves in your hands or feet. You may start to have some numbness or tingling (slight stinging or poking feeling) in your fingers, toes, or both. This may last for a short time or for the rest of your life, depending on how long you’re on chemotherapy. Your healthcare provider can give you medicine or change the dose of your chemotherapy to help ease your symptoms.
How to manage neuropathy
- Exercise regularly (have an exercise routine).
- Quit smoking, if you smoke.
- Don’t drink large amounts of alcohol.
