What Akynzeo is used for

This medicine is used to prevent nausea (feeling sick) and vomiting caused by cancer chemotherapy in adult patients.

It is a combination medicine which contains two active ingredients. The active ingredients are called netupitant and palonosetron.

Netupitant belongs to a group of medicines called ‘neurokinin-1 (NK1) receptor antagonists’.

Palonosetron belongs to a group of medicines called ‘serotonin (5-HT3) receptor antagonists’.

Akynzeo works by blocking the actions of substances in your body and brain that are thought to cause nausea and vomiting.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is not addictive.

This medicine is available only with a doctor’s prescription.

There is not enough information to recommend its use in children under the age of 18 years.
