The short answer
After chemotherapy, the drug is present in body fluids. NCI advises patients and caregivers to prevent contact with those fluids using ordinary steps: closing the lid and flushing twice, wearing gloves for spills and soiled items, washing hands, and washing soiled linens separately.
NCI says patients and caregivers need to take special care to prevent contact with body fluids after chemotherapy.
The fluids NCI lists are urine, stools, sweat, mucus, blood, vomit and fluids from sex.
Closing the lid and flushing twice after using the toilet is one of the specific measures given.
Sitting down to urinate is recommended, which reduces splashing.

The whole article, with every detail and caution.
This page is for people caring for someone on chemotherapy at home. It explains the simple bathroom, glove and laundry steps that limit contact with body fluids after treatment.
The reason behind the rules
NCI states it plainly: after receiving chemotherapy, you and your caregivers need to take special care to prevent contact with your body fluids. The fluids it names are urine, stools, sweat, mucus, blood, vomit and those from sex.
The precautions NCI lists are about handling body fluids. They are steps for the bathroom, gloves and laundry. If you are unsure about anything else, such as contact with children, ask your care team.
That matters. Families sometimes read a list like this and quietly start keeping their distance. That is the last thing anyone in treatment needs.
In the bathroom
NCI's specific bathroom measures are:
- Close the lid and flush twice after using the toilet
- Sit on the toilet to urinate
- Wash your hands with soap and water after using the restroom
- Clean splashes from the toilet with bleach wipes
The order is lid down first, then flush, then flush again.
Keeping bleach wipes in the bathroom makes splashes easy to clean.
Gloves, and when to use them
NCI advises using gloves when handling body fluids, and washing your hands after removing the gloves.
That last clause is the one people skip. Gloves are not a substitute for handwashing. They reduce contact, then you wash anyway.
If incontinence is a factor, NCI recommends wearing disposable pads or diapers and wearing gloves when handling them.
Buy a box of disposable gloves before you need them. Nobody wants to be searching a grocery store at 2 a.m.
Laundry
NCI's instruction is to wash linens soiled with body fluids separately.
Separately means a load of their own, not tossed in with the towels. If something is soiled overnight, put it straight in the machine rather than in a shared laundry basket where it sits against everything else.
Sex
NCI includes fluids from sex among the body fluids to avoid contact with, and lists using condoms during sex among the precautions.
This is a subject that goes unasked far too often, usually because both people assume the other has been told. Ask your oncology team directly. They will not be surprised by the question, and the answer depends on the drugs you are receiving.
How long does this last?
NCI says the length of time differs depending on the policy where you receive treatment and the drugs you receive. It gives no single number.
NCI says your doctor or nurse will tell you how long to follow these steps. Your oncology nurse can tell you the window for your specific regimen. Ask on your first treatment day and write the answer on the fridge, because you will not remember it later.
A note to caregivers
These precautions are undramatic on purpose. Gloves, a lid, a second flush, a separate wash. They take almost no time and they protect you without turning your home into a hospital.
Do them steadily and without commentary. The person you are caring for already feels like a source of trouble more often than they should, and quiet competence is worth a great deal.
Common questions
Is it dangerous for me to be around someone on chemotherapy?
NCI's advice is about preventing contact with body fluids. The precautions it lists are about handling urine, stool, vomit and soiled laundry, not about staying away from the person. Ask your team if you have questions about your own home.
Why flush twice?
NCI lists closing the lid and flushing twice after using the toilet among the home safety measures. Your team can explain how they apply to your drugs.
What do I do about splashes?
NCI's guidance includes cleaning splashes from the toilet with bleach wipes. Keeping a container of them in the bathroom makes them easy to reach.
Does this apply to sex?
NCI's list includes fluids from sex among the body fluids to avoid contact with, and it includes using condoms during sex among the precautions. Your team can tell you how long these apply in your case.

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.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
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.
