Managing nausea at work
Many people keep working, by planning around the cycle rather than pushing through the worst days. Sickness usually follows a predictable pattern, so the job becomes arranging work around the hard days rather than enduring them at a desk. The single most useful change is getting the treatment appointment on a day that leaves the bad stretch over a weekend — ask for it early.

The short answer
Can you keep working through chemotherapy sickness?
Many people do, by planning around the cycle rather than trying to push through the worst days. Sickness usually follows a predictable pattern, and once you know which days are difficult, the job becomes arranging work around them rather than enduring them at a desk.
The single most useful change is getting the treatment appointment on a day that leaves the bad stretch falling over a weekend or your lightest working days. Ask for that specifically — units are often more flexible than people assume, particularly if asked early.
Take the medicine on schedule, not at work
Anti-sickness medicines work best taken preventively at set times, including on days you feel fine. Treating them as something to take at the office when sickness arrives is the commonest reason they appear not to work. Set an alarm on your phone.
Ask your team which days after a cycle are likely to be hardest. Every plan below depends on that answer.The desk kit
What to keep at work
- Your anti-sickness medicine, with an alarm set for each dose
- Plain dry snacks — biscuits, khakhra, roasted chana — for an empty stomach
- A bottle of water, and something cold if you have a fridge
- Ginger tea bags or a small piece of fresh ginger
- Something with a clean sharp smell, such as a cut lemon or mint
- A spare shirt and a sealable bag, kept in a drawer
- Wet wipes, a small towel and a toothbrush
- Your treatment card, and the helpline number saved in your phone

Ask an oncologistGetting through the day
What actually helps at work
Most of it is about smell, an empty stomach and having somewhere to go for ten minutes.
Never let the stomach empty
Something plain every couple of hours rather than a proper lunch break. An empty stomach makes sickness worse for most people, and long meetings without food are a common trigger.
Keep to hand
- Dry biscuits or khakhra
- A banana
- Cool water, sipped steadily
Get away from food smells
Canteens and shared kitchens at lunchtime are the worst part of many working days. Eat at your desk or outside, and step out while others are heating food.
Strong perfume and air fresheners set sickness off as reliably as food does.Have somewhere to go
Ten minutes in fresh air, or a quiet room to sit in, usually breaks a wave of nausea. Knowing in advance where that place is removes most of the anxiety about being caught out.
Sit rather than lie, and move a little
Short walks help more than sitting still all day. Lying down after eating worsens both sickness and acidity, so if you rest at lunchtime, stay upright.
Schedule the demanding things
Put the meetings and travel that matter in the good week before the next cycle. Move routine and desk-based work into the difficult days where you can.
Keep drinking
Do not cut fluids to avoid the toilet or because drinking makes you feel sick. Small sips through the day, cool rather than hot. Dehydration is what turns a hard week into a hospital visit.
!
Do not finish the day with these
A fever · nothing staying down for most of a day · vomit containing blood or looking like coffee grounds · severe stomach pain · feeling faint, confused or very unwell. Leave work and go to the nearest emergency department, saying clearly that you are on chemotherapy. Do not take an extra dose of anything to get through the afternoon, and do not take paracetamol to bring a temperature down before being seen.
At the workplace
What to tell people, and what you can ask for
You do not have to tell everyone, or discuss the diagnosis at all. Most people find that telling one manager, and perhaps one colleague who sits nearby, covers what they need. Saying you have a medical condition requiring treatment, and may need to step out or work from home on certain days, is usually enough.
What is worth asking for
Working from home on the difficult days. Flexible start times, since mornings are often the worst. A quiet place to sit for ten minutes. Meetings scheduled in your good week. And the treatment appointment itself arranged around your work rather than the other way round.
Ask early, and in writing
Adjustments are far easier to arrange before you have missed deadlines than afterwards. Put the request in an email so there is a record, and ask your team for a letter if your employer wants documentation.
Be realistic about the difficult days
Some people work right through and some cannot, and that is largely about which drugs you are on rather than about determination. If you are taking unpaid leave, or the work is making the treatment harder to tolerate, tell your oncologist — that changes the conversation about timing and sometimes about the anti-sickness plan.
If sickness is bad enough to stop you working, it is bad enough to be reported. That is not a small complaint.Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
Being straight with you
What this page cannot tell you
It cannot tell you whether you are well enough to work. That depends on your treatment, your blood counts and how you are tolerating it, and during the low-count days your team may advise avoiding crowds and public transport for reasons unrelated to sickness.
It also cannot tell you to take anything extra to get through a day. Nothing here should be used to change a prescribed medicine, and taking a double dose to survive a meeting is not a decision to make at a desk.
What to do next
Ask your team which days after a cycle are likely to be worst, and ask whether the treatment day can be moved to suit your working week. Put the desk kit together. Set alarms for the anti-sickness medicine. Tell one person at work. And if sickness is stopping you working, say that at your next contact.
Questions we are asked
Common questions about working through treatment
Can I ask for my treatment on a particular day?
Very often yes, if you ask early. Many people arrange treatment so the difficult days fall over a weekend or their lightest working days. It is one of the most useful adjustments available and it costs the unit nothing, but it has to be requested rather than assumed.
Do I have to tell my employer I have cancer?
Not necessarily. Many people tell one manager only that they have a medical condition requiring treatment and may need adjustments on certain days. That is usually enough to arrange what you need without discussing the diagnosis with colleagues.
Should I take the anti-sickness tablets at work when I feel sick?
Take them on the schedule you were given, at set times, including on days you feel fine. They work far better preventively than as a rescue, and treating them as something for when sickness arrives is the commonest reason a plan appears to have failed. Set phone alarms.
The canteen smell sets me off. What can I do?
Eat at your desk or outside rather than in the canteen, and step away while others heat food. Carry something with a clean sharp smell such as a cut lemon or mint. Ask to sit further from the kitchen if that is possible. Smell is the biggest workplace trigger by far.
Is it safe to drive during treatment?
Ask your team, because several anti-sickness medicines cause drowsiness and tiredness builds through a course. Many people avoid driving in the days straight after a cycle. If you are feeling faint, sleepy or unable to concentrate, do not drive and arrange a lift instead.
Should I take leave instead?
That depends on your work, your finances and how you are tolerating treatment. Many people manage with adjustments rather than full leave — working from home on hard days, or shifting hours. Tell your team if income is a pressure, as they can help with timing and documentation.
What if I vomit at work?
Having a spare shirt, a sealable bag, wipes and a toothbrush in a drawer turns it from an emergency into an inconvenience, which is the point of carrying them. Tell your team it happened, because sickness that reaches that point usually means the plan needs strengthening.
Will it be like this for the whole course?
Often it improves, because the anti-sickness plan gets tuned after the first cycles. What tends to build instead is tiredness, which affects work differently and may matter more by the end. Plan for the pattern you actually have rather than the one you started with.
