Fosnetupitant+palonosetron
About Fosnetupitant+palonosetron
Fosnetupitant+palonosetron is a specialised prescription injection used to prevent nausea and vomiting caused by chemotherapy. It is given to patients undergoing cancer treatments that are highly likely to cause severe stomach upset. This medicine works by blocking the specific chemical signals in the body that trigger the urge to vomit.
Because this medicine is given as an injection, a healthcare professional will give it to you as a single dose shortly before your chemotherapy session begins. Since it bypasses the digestive system, you do not need to worry about eating food before your dose. Making simple lifestyle adjustments, such as eating smaller meals and resting upright after eating, can also help support your recovery.
While receiving this treatment, you may experience common side effects like headaches, constipation, or feeling tired. Most of these effects are mild and temporary, but you should tell your doctor immediately if you notice any unusual or severe symptoms. Your healthcare team is always available to help you manage these side effects.
Before starting your treatment, talk to your doctor if you have a history of liver damage, heart conditions, or chemical imbalances in your blood. You should not take this medicine if you have had a severe allergic reaction to similar anti-nausea medications in the past.
This medicine can interact with certain antidepressants and heart medications, which may increase the risk of heart rhythm issues. It is also important to avoid alcohol and smoking during your treatment cycle, as they can irritate your stomach. Always consult your doctor if you are pregnant, breastfeeding, or an older adult before receiving this injection.

Patients Concern
Disease/Condition Glossary
Nausea and vomiting: Nausea is a feeling of uneasiness in the stomach that often comes before vomiting. On the other hand, vomiting is the forcible voluntary or involuntary emptying of stomach contents through the mouth. In short, nausea and vomiting are not diseases but are symptoms of many conditions like infections, motion sickness, an early stage of pregnancy, and gastroparesis (slow stomach emptying). A receptor in our brain known as the chemoreceptor zone (CTZ) controls vomiting.
