1. what akynzeo is and what it is used for
What Akynzeo is
- Akynzeo contains two medicines (‘active substances’) called: netupitant
- palonosetron.
What Akynzeo is used for
Akynzeo is used to help prevent adults with cancer feeling sick (nausea) or being sick (vomiting) while having cancer treatment called ‘chemotherapy’.
How Akynzeo works
Chemotherapy medicines can cause the body to release substances called serotonin and substance P. This stimulates the vomiting centre in the brain, making you feel or be sick. The medicines in Akynzeo attach to the receptors in the nervous system through which serotonin and substance P work: netupitant (an NK1 receptor antagonist) blocks the receptors for substance P, and palonosetron (a 5-HT3 receptor antagonist) blocks certain receptors for serotonin. By blocking the actions of substance P and serotonin in this way, the medicines help prevent the stimulation of the vomiting centre and the resulting sickness.
2. what you need to know before you take akynzeodo not take akynzeo if: you are allergic to netupitant or palonosetron, or any of the other ingredients of this medicine (listed in section 6). if you are not sure, talk to your doctor, pharmacist or nurse before taking this medicine.

3. How to take Akynzeo
Always take this medicine exactly as your doctor has told you. Check with your doctor, pharmacist or nurse if you are not sure.
How much to take
- The recommended dose is one capsule (each capsule contains 300 mg of netupitant and 0.5 mg of palonosetron).
- Take the capsule about 1 hour before you start your chemotherapy cycle.
- You can take Akynzeo with or without food.
Akynzeo is taken before the chemotherapy to prevent sickness and feelings of sickness from developing. Do not take Akynzeo in the days after you have chemotherapy – unless you are about to have another chemotherapy cycle.
If you take more Akynzeo than you should
The usual dose is 1 capsule. If you think you may have taken more than you should, tell your doctor straight away. The symptoms of overdose may include headache, dizziness, constipation, anxiety, palpitations, euphoric mood and pain in the legs.
If you forget to take Akynzeo
If you think you have forgotten to take your dose, tell your doctor straight away.
If you stop taking Akynzeo
Akynzeo is taken to help prevent you feeling and being sick when you are having chemotherapy. If you do not want to take Akynzeo, discuss this with your doctor. If you decide not to take Akynzeo (or another similar medicine), your chemotherapy is likely to make you feel sick and be sick.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
