De un vistazo
Palonosetron is an anti-sickness medicine used to prevent nausea and vomiting during chemotherapy.
It works by blocking a chemical in the body called serotonin, which can cause sickness.
You can take it as a capsule an hour before chemotherapy or as an injection during treatment.
Common side-effects include headache, constipation, diarrhoea, and feeling dizzy or tired.
If you have an irregular heartbeat, or severe constipation, tell your doctor.
In rare cases, stiff muscles, high temperature, fast heartbeat, or confusion could be serious.
Seek medical help straight away if you experience signs of serotonin syndrome.
About palonosetron
Tipo de medicamento | An anti-sickness (antiemetic) medicine - a serotonin (5HT3) receptor antagonist |
Usado para | Prevention of nausea and vomiting (sickness) associated with quimioterapia in adults |
También llamado | Akynzeo® (which contains palonosetron with netupitant) |
Disponible como | Capsules (Akynzeo®) and injection |
Palonosetron is an anti-sickness medicine, also known as an antiemetic. It is a serotonin receptor antagonist. It is prescribed to stop you from feeling sick (nauseated). It works by blocking the effect of a naturally produced chemical in your body, called serotonin. Serotonin is also referred to as 5HT3.
Quimioterapia can cause the release of an increased amount of serotonin in your body. There are tiny areas in your small intestine and brain called 5HT3 receptors. Serotonin acts on these receptors and causes you to feel sick. Palonosetron works by blocking serotonin from acting on the receptors, and this stops you from feeling sick or being sick (vomiting).
There is a brand of palonosetron which contains another anti-sickness medicine called netupitant - the brand is called Akynzeo®. Netupitant works by blocking the effect of another naturally produced chemical in your body, called substance P.
Before taking palonosetron
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking palonosetron it is important that your doctor knows:
If you are pregnant or breastfeeding. You should not take this medicine if you are expecting, or breastfeeding, a baby.
If you have had a problem with severe constipation.
If you have been told you have an irregular heartbeat.
Si alguna vez has tenido una reacción alérgica a un medicamento.
Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.
How to take palonosetron capsules
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about palonosetron, and it will also provide you with a full list of the side-effects which you could experience from taking it.
Take the capsule exactly as your doctor tells you to. You will be asked to take a single dose of one Akynzeo® capsule (containing 500 micrograms of palonosetron), one hour before your chemo treatment starts.
Swallow the capsule whole - it may help to take it with a drink of water. You can take the capsule either with or without food.
Alternatively you may be given palonosetron as an injection during your chemotherapy appointment.
Obteniendo el máximo de tu tratamiento
You will only be given palonosetron before you have chemotherapy. If you need anything for sickness after your treatment, you will be given a different medicine to take.
Even if you do not feel like eating or drinking, try to sip water regularly to prevent you from becoming lacking in fluids (dehydrated). Also, rather than trying to eat three main meals a day, try eating small, simple but nourishing snacks, every few hours.
Can palonosetron cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the more common ones associated with palonosetron. The best place to find a full list of the side-effects which can be associated with your medicine, is from the manufacturer's printed information leaflet supplied with the medicine. Alternatively, you can find an example of a manufacturer's information leaflet in the reference section below. Speak with your doctor or pharmacist if any of the following become troublesome.
Common palonosetron side-effects (these affect fewer than 1 in 10 people) | ¿Qué puedo hacer si experimento esto? |
Dolor de cabeza | Drink plenty of water and ask your doctor to prescribe/recommend a suitable painkiller |
Estreñimiento | Try to eat a well-balanced diet, and drink several glasses of water each day. Let your doctor know if this continues |
Diarrea | Drink plenty of water to replace lost fluids. Let your doctor know if this continues |
Sensación de mareo o cansancio | No conduzca ni utilice herramientas o máquinas mientras esté afectado |
Importante: in a very few people, medicines like palonosetron can cause a problem called serotonin syndrome. Although this occurs only rarely, should you develop stiff or shaky muscles, a very high temperature (fever), a fast heartbeat, or become confused or agitated, you should call for medical assistance straightaway.
Si experimenta otros síntomas que cree que pueden deberse al medicamento, hable con su médico o farmacéutico para obtener más consejos.

Preguntas frecuentes
Can palonosetron be used to prevent sickness from causes other than chemotherapy?
No, palonosetron is specifically prescribed for the prevention of nausea and vomiting associated with chemotherapy in adults. If you are experiencing sickness for other reasons, a different medicine would be used.
Are there different forms of palonosetron available?
Yes, palonosetron is available as capsules (often in the brand Akynzeo®, which also contains netupitant) and as an injection. Your doctor will decide which form is most suitable for your treatment.
How quickly does palonosetron start to work after I take it?
You should take the palonosetron capsule one hour before your chemotherapy treatment begins. This timing allows the medicine to start working to block serotonin receptors before the chemotherapy induces the release of increased serotonin, preventing you from feeling sick.
Is there anything specific I should do if I am given palonosetron as an injection?
If you are given palonosetron as an injection, it will be administered during your chemotherapy appointment. You don't need to do anything specific in preparation for the injection beyond following your doctor's general instructions for your chemotherapy session.
What is netupitant and why is it sometimes given with palonosetron?
Netupitant is another anti-sickness medicine that works differently from palonosetron. It blocks the effect of a natural body chemical called substance P. When palonosetron is combined with netupitant in the brand Akynzeo®, it offers a broader approach to preventing chemotherapy-induced nausea and vomiting by targeting two different chemical pathways.
If I am pregnant or breastfeeding, can I still take palonosetron if my doctor thinks it's necessary for my chemotherapy?
No, if you are pregnant or breastfeeding, you should not take palonosetron. It is important to inform your doctor about your pregnancy or breastfeeding status so they can consider alternative anti-sickness treatments that are safe for you and your baby.
