What is anti-sickness medication done with?

Anti-sickness medicines are also called antiemetics. They work through different pathways involved in nausea and vomiting. A clinician may choose one medicine or combine medicines according to the treatment being given, your previous symptoms, and other medicines you take.

These medicines may be given before, during, or after chemotherapy, radiotherapy, surgery, or another treatment that can upset the stomach. They can also be prescribed when nausea has another cause. Some are taken by mouth, while others are given through a vein, injection, or another route when swallowing is difficult.

Take the medicine exactly as directed, including any dose scheduled before treatment. Tell your oncology team if nausea starts despite the plan, because changing the timing or adding a different type may help. Keep fluids nearby and try small, frequent sips if your stomach feels unsettled.

Report constipation, diarrhoea, sleepiness, dizziness, headache, or other new effects. Do not add an over-the-counter remedy without checking, since it may interact with your cancer medicines.

Contact your treatment team promptly if you cannot keep fluids or medicines down, vomit repeatedly, or pass very little urine. Seek urgent medical help for severe weakness, confusion, fainting, blood in vomit, or severe abdominal pain.

Ask which anti-sickness medicine to take, when to take it around treatment, what to do after vomiting a dose, and which symptoms should trigger a same-day call.
