Summary
Netupitant and palonosetron are used to prevent nausea and vomiting caused by chemotherapy, which is a treatment for cancer that often leads to these symptoms. They are especially effective for patients undergoing highly emetogenic chemotherapy, which refers to treatments that are very likely to cause severe nausea and vomiting.
Netupitant works by blocking signals in the brain that trigger nausea, while palonosetron blocks serotonin, which is a chemical that can cause nausea and vomiting. Together, they target different pathways to provide a comprehensive approach to managing these symptoms.
The usual adult dose is a single capsule taken before chemotherapy. This capsule contains 300 mg of netupitant and 0.5 mg of palonosetron. This single-dose approach is designed to provide protection against nausea and vomiting for several days after chemotherapy.
Common side effects include headache, fatigue, and constipation. Netupitant may cause hiccups, while palonosetron can lead to dizziness. Although rare, serious side effects like heart rhythm changes can occur, so it's important to report any unusual symptoms to a healthcare provider.
Netupitant and palonosetron should not be used by individuals with known allergies to these substances. Caution is advised for patients with heart conditions, as both can affect heart rhythm. Netupitant should be used carefully in patients with liver problems, as it is processed by the liver.
Indications and Purpose
How does combination of netupitant and palonosetron work?
Netupitant and palonosetron work together to prevent nausea and vomiting. Netupitant blocks certain signals in the brain that trigger nausea, while palonosetron blocks serotonin, which is a chemical that can cause nausea and vomiting. By targeting different pathways, they provide a comprehensive approach to managing these symptoms. This combination is particularly effective for patients undergoing chemotherapy, which often causes severe nausea and vomiting. Together, they help improve the patient's comfort and quality of life during treatment.
How effective is combination of netupitant and palonosetron?
Clinical trials have shown that netupitant and palonosetron effectively prevent nausea and vomiting in patients undergoing chemotherapy. Netupitant, which blocks certain brain signals, has been proven to reduce nausea episodes. Palonosetron, which blocks serotonin, has shown effectiveness in preventing nausea and vomiting. Together, they provide a comprehensive approach, with studies indicating a significant reduction in nausea and vomiting compared to other treatments. This combination is particularly effective for patients receiving highly emetogenic chemotherapy, which refers to treatments that are likely to cause nausea and vomiting.

Warnings and Precautions
Are there harms and risks from taking combination of netupitant and palonosetron?
Common side effects of netupitant and palonosetron include headache, fatigue, and constipation. Netupitant may cause hiccups, while palonosetron can lead to dizziness. Significant adverse effects, although rare, include allergic reactions, which can cause symptoms like rash, itching, or swelling. Both medicines share the potential for causing serious side effects like heart rhythm changes, which can be dangerous. It's important for patients to report any unusual symptoms to their healthcare provider immediately.
Can I take combination of netupitant and palonosetron with other prescription drugs?
Netupitant can interact with drugs that are metabolized by the liver, such as certain antibiotics, antifungals, and medications for heart conditions, which can alter their effectiveness. Palonosetron may interact with other drugs that affect heart rhythm, increasing the risk of heart problems. Patients should inform their healthcare provider of all prescription medications they are taking to avoid harmful interactions. Regular monitoring and possible dose adjustments may be necessary to ensure safe use of these medications together.
Can I take combination of netupitant and palonosetron if I am pregnant?
The safety of netupitant and palonosetron during pregnancy is not well-established. Animal studies have shown some risks, but there is limited data on human pregnancies. Netupitant may pose a risk to the developing fetus, while palonosetron's effects are less clear. Both medicines should only be used during pregnancy if the potential benefits justify the potential risks to the fetus. Pregnant women should discuss with their healthcare provider to weigh the risks and benefits before using these medications.
Can I take combination of netupitant and palonosetron while breastfeeding?
There is limited information on the safety of netupitant and palonosetron during lactation. It is not known if netupitant passes into breast milk, but caution is advised. Palonosetron is also not well-studied in breastfeeding, and its presence in breast milk is unknown. Due to the lack of data, breastfeeding mothers should consult their healthcare provider to carefully consider the potential risks and benefits before using these medications.
