Side Effects by — Chemotherapy Class
The side effects you are likely to have depend on which class of chemotherapy you are receiving. Knowing your class means your team can tell you what to expect before treatment starts — and what is worth calling about the same day.

- Each class has its own pattern — Platinum-based, taxane-based, anthracycline-based, and antimetabolite drugs each produce a distinct set of expected effects.
- Prediction is possible — Your oncologist knows which effects your class typically causes and can describe them before your first infusion.
- Some effects cross class lines — Low blood counts, fatigue, and infection risk are common across most chemotherapy classes.
- Knowing what is expected helps — When you know what is typical for your class, you are better placed to recognise what is not — and to report it early.

Different classes of chemotherapy produce distinct, predictable patterns of side effects. Knowing your class lets your oncologist tell you what is likely before you start — and what is unexpected and worth reporting. Your care plan is built around these known patterns, which is why guidance from your team can be specific to you.
Which class of chemotherapy causes which side effects?
Platinum-based drugs typically produce nausea in the first few days, kidney stress that your team manages with extra fluids, and tingling or numbness in the hands and feet that builds over several cycles. Possible changes to hearing are also associated with this class.
Taxane-based drugs cause nerve tingling and numbness in the hands and feet, joint and muscle aches that peak in the two to three days after each infusion, and usually significant hair loss.
Anthracycline-based drugs commonly cause complete hair loss, nausea in the first 48 hours, and mouth sores. Because these drugs can affect the heart at high cumulative doses, periodic heart checks are a routine part of your care — not a sign something has gone wrong.
Antimetabolites tend to irritate the lining of the mouth and bowel, producing mouth sores, loose motions, and changes to the skin and nails. Sun sensitivity during treatment is common.
Topoisomerase inhibitors typically produce nausea and diarrhoea, and blood counts tend to fall more sharply than with some other classes — your team will monitor closely.
Vinca alkaloids are unusual in producing constipation rather than diarrhoea, alongside nerve tingling in the hands and feet. Report constipation early, because it can worsen quickly in this setting.
Can you know what side effects to expect before chemotherapy starts?
Yes, to a useful degree. Your oncologist knows which class you are on, and each class has a well-established pattern. Before your first infusion, ask your team to describe what is typical for your specific treatment.
Within any class, individual experience varies. Your kidney and liver function, your age, and your overall fitness all affect how severe each effect is and how long it lasts.
Your team tracks your blood results and your reported symptoms at every visit to spot early if your experience is tracking within the expected range — or if something needs to change.

What should you ask before your first infusion?
- Ask which class of chemotherapy you are receiving.
- Ask which side effects are typical for that class, and when they usually begin.
- Ask which symptoms should prompt a same-day call to your team.
- Ask which symptoms mean you should go directly to emergency care.
- Ask what blood tests will be done at each visit and what your team is watching for.
- Tell your team every medicine, supplement, and herbal remedy you are taking.
- Ask how to contact your team outside of clinic hours.
What side effects are common across most chemotherapy classes?
Low white blood cell counts occur across nearly all chemotherapy classes. NCCN and ASCO guidelines both classify fever during chemotherapy as requiring same-day assessment — not home management. This applies regardless of which class you are on.
Fatigue affects most people on chemotherapy. Anaemia, a fall in red blood cells, can develop over weeks and adds to tiredness and breathlessness. Both are treatable when your team knows about them.
Nausea occurs with many classes, though its timing differs. Your team can adjust anti-nausea medicines between cycles — tell them what you experienced so they can improve what you receive before the next infusion.
How do you track and report side effects during treatment?
Before your first infusion
Ask your oncologist which class you are receiving and what side effects are typical for it. Write down the answers.
In the first week of your first cycle
Note any new symptoms — their severity and when they appeared. The first cycle shows you how your body responds to this class.
At every clinic visit
Report every symptom, including ones you think are minor or expected. Your team uses what you report to decide whether adjustments are needed.
Between visits
Keep a short daily note of how you feel. A pattern of worsening is easier to see with a record — and gives your team precise information.
When something concerns you
Call your team the same day. Symptoms that are unexpected for your class, or expected symptoms that are suddenly worse, need early review — not a wait-and-see approach.

Frequently asked questions
What is the difference between the main classes of chemotherapy?
Each class works by a different mechanism — some disrupt the way cells copy their DNA, others interfere with the machinery that allows cells to divide, and others mimic building blocks that cells need to grow. These different mechanisms produce different side effect patterns. Your oncologist can tell you which mechanism applies to your treatment and why that class was chosen for your cancer.
Will I lose my hair? Does it depend on which class I am on?
Yes, hair loss depends strongly on your class. It is most likely — and often complete — with anthracycline-based drugs, and common with taxane-based drugs. It is less typical with antimetabolites, though some thinning is possible. Your oncologist can tell you what level of hair loss to expect before you start. In most cases hair returns after treatment ends, though timing varies between individuals.
How long do chemotherapy side effects last after treatment ends?
Effects that come and go between cycles — nausea, low blood counts, mouth sores — generally resolve within weeks of the last dose. Nerve tingling from platinum-based or taxane-based drugs can persist for months and in some people does not fully resolve. Fatigue often lasts longer than the treatment itself. Your oncologist will tell you what is expected for your specific class after the final cycle.
Can my chemotherapy be changed to a different class if side effects are severe?
Sometimes, yes. If a side effect is severe or not settling, your oncologist may adjust the dose, add medicines to manage the effect, pause treatment, or consider an alternative regimen. That decision weighs the severity of the effect against how well the treatment is working for the cancer. The essential step is to report what you are experiencing — your team cannot make adjustments for symptoms they do not know about.
Why do some chemotherapy classes cause tingling in the hands and feet?
Platinum-based and taxane-based drugs — and to a lesser degree vinca alkaloids — can affect the long nerve fibres that carry sensation to the hands and feet. This is called peripheral neuropathy. It is one of the more characteristic effects of these classes, which is why your team asks about it specifically at each visit. Reporting it early matters: if tingling is progressing, your team may adjust the dose to limit further worsening over remaining cycles.
What should I do if my side effects are much worse than my team described?
Call your team the same day. The patterns described for each class are based on typical responses, and individual experience varies — some people react more severely, and sometimes what seems like a predictable effect needs different treatment. If something feels significantly worse than what you were told to expect, or simply feels wrong in a way you cannot explain, that is the signal to call today rather than wait and see.
