The short answer
This guide helps you prepare food, fluids, medicines, transport, help, and monitoring around the treatment plan. It is a planning tool, not an individual medical, legal, or coverage decision.
The main goal is to prepare food, fluids, medicines, transport, help, and monitoring around the treatment plan.
Ask what is common after this specific treatment and what is not.
Follow the prescribed preventive-medicine schedule exactly.
Plan help for driving, meals, children, pets, and overnight needs when advised.

What a treatment day asks of you
This page is for people getting chemotherapy who want to plan for treatment days. Much of the work of a treatment day happens before and after the appointment itself. This page follows the National Cancer Institute's patient booklet Chemotherapy and You and NCI's chemotherapy page. They cover eating, getting there and back, help at home, and what to watch for once you are home.
Find out how long you will be there
Session length is not standard. NCI does not publish a typical figure. It lists "How long does each treatment last?" as a question to ask your doctor. Ask it before your first appointment. The answer tells you:
- Whether you need a meal
- Whether someone can wait with you
- What to arrange at home
Bring what makes a long sit easier:
- Something to read or watch
- Headphones
- A phone charger
- A layer you can add if the room is cold
- Your current medicine list
Eating and drinking before you go
There is no single right answer here. NCI says so directly: "Some people feel better when they eat a light meal or snack before chemotherapy. Others feel better when they have chemotherapy on an empty stomach (nothing to eat or drink for 2 to 3 hours before treatment)."
Afterwards, NCI's instruction is more specific: "After treatment, wait at least 1 hour before you eat or drink."
Have you been given separate written instructions about fasting, fluids, or taking your usual medicines on treatment morning? Those override the general advice. Ask which of your regular medicines to take, and at what time, before the day arrives.
Getting there, and why driving yourself may not work
NCI lists "Should someone drive me to and from treatments?" among the questions to ask your doctor.
One reason is fatigue. NCI says "the most common side effect is fatigue, which is feeling exhausted and worn out." To prepare for it, NCI suggests "asking someone to drive you to and from chemotherapy" and "planning time to rest on the day of and day after chemotherapy." You can also ask whether any medicine you get that day could make you drowsy.
It can help to plan the first session as though you will not be driving home. Ask the social worker or navigator early whether your clinic or insurer offers help with rides. Don't wait until the morning itself.
The days after
Treatment days do not end at the door. NCI suggests "asking for help with meals and childcare on the day of and at least one day after chemotherapy." NCI's booklet is clear about accepting offers: "Accept help. When your family or friends offer to help, let them. They can help care for your children, pick up groceries, run errands, drive you to doctor's visits, or do other chores."
In practice, that can mean:
- Shopping and cooking before you go, not after.
- Having easy food and fluids in the house.
- Having any anti-nausea or other medicines your team prescribed filled and at home before the first dose.
The one thing to have at home
A thermometer. NCI's booklet says to "check for fever at least once a day, or as often as your doctor or nurse tells you to."
CDC says to call your doctor immediately if you have a temperature of 100.4°F (38°C) or higher during chemotherapy. CDC calls it a medical emergency. Fever may be the only sign of an infection, and an infection during chemotherapy can be life-threatening. NCI's booklet says to call even on the weekend or in the middle of the night, and to call if you have chills or sweats. It says not to take aspirin, acetaminophen, ibuprofen, or other fever-lowering drugs without first talking with your doctor or nurse.
NCI says "infections during cancer treatment can be life threatening and require urgent medical attention." Call your health care team if you have signs of an infection. Write down the number to call after hours. You can read more about how sources word the fever threshold.
Work and money
NCI notes that "many employers are required by law to change your work schedule to meet your needs during cancer treatment." It adds that many people can work during chemotherapy, as long as they match their schedule to how they feel. A social worker can tell you more about these laws. On cost, NCI suggests talking with your health insurance company and with the business office where you go for treatment.
Safety boundaries
This guide cannot diagnose a symptom. It cannot set an individual emergency threshold, determine legal authority, or guarantee insurance coverage. Follow the oncology team's written instructions. Do not change prescribed medicines, treatment, diet restrictions, activity restrictions, oxygen, devices, or wound care independently.
If someone may be in immediate danger, contact local emergency services. For thoughts of suicide or self-harm in the United States, call or text 988. Elsewhere, use the local crisis service.

Common questions
How long will a treatment session take?
Session length is not standard, and NCI does not publish a typical figure. It lists how long each treatment lasts as a question to ask your doctor. Ask before your first appointment, because the answer decides whether you need a meal, whether someone can wait with you, and what to arrange at home.
Should I eat before chemotherapy?
There is no single right answer. NCI says some people feel better after a light meal or snack, while others feel better on an empty stomach with nothing to eat or drink for 2 to 3 hours beforehand. After treatment, NCI advises waiting at least 1 hour before you eat or drink. Written instructions from your own team override the general advice.
Can I drive myself home?
Ask your doctor. NCI lists "Should someone drive me to and from treatments?" as a question to ask. NCI says fatigue is the most common side effect of chemotherapy, and suggests asking someone to drive you to and from chemotherapy as one way to prepare for it. You can also ask whether any medicine you get that day could make you drowsy. It can help to plan the first session as though you will not be driving.
What should be in the house before the first treatment?
A thermometer, easy food and fluids, and any anti-nausea or other medicines your team has prescribed, already filled. NCI suggests asking for help with meals and childcare on the day of and at least one day after chemotherapy. In practice that can mean shopping and cooking before you go, not after.
When do I call about a fever?
CDC says to call your doctor immediately if you have a temperature of 100.4°F (38°C) or higher during chemotherapy. CDC calls it a medical emergency, because fever may be the only sign of an infection. NCI says to check for fever at least once a day, or as often as your doctor or nurse tells you to, and to call even if it is the weekend or the middle of the night. Write down the number to call after hours.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
High-risk topic — talk to your care team. This topic can involve urgent, individual medical decisions. This page is general education only: it cannot tell you whether your situation is an emergency or what you personally should do. Follow your oncology team's instructions and contact them for individual guidance.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
