Chemotherapy for cancer can cause vomiting by triggering the release of large amounts of serotonin in the gut. Serotonin interacts with cell structures known as 5-HT3 receptors in the gut and brain stem. Palonoesetron is in a class of drugs known as 5-HT3 antagonists. These drugs block the activity of this receptor, thereby preventing vomiting.
This medication is given as injection into a vein (intravenous). Usually, palonosetron is given about 30 minutes before chemotherapy. For patients receiving multiple chemotherapy doses over the course of weeks or months, this drug may be given before each dose. The exact dose, schedule, and route of administration depends on the type of cancer being treated, how well the cancer is responding to the drug, height, weight, general health, and several other factors. Your doctor will determine the approach that is best for you. Palonosetron is used to prevent nausea and vomiting only; it cannot be used to treat nausea and vomiting that has already occurred following chemotherapy.
To prevent problematic interactions between palonosetron and other drugs, be sure to tell your doctor if you are allergic to any medications, and what other medications and supplements you are currently taking. You should also inform your doctor if you have or ever had liver tumor, liver disease, kidney disease, are pregnant, planning to become pregnant, or are breastfeeding.
Possible side effects of palonosetron may include:
- Difficulty urinating
Some of palonosetron’s side effects can be serious. Call your doctor immediately if you experience any of these symptoms:
- Difficulty breathing or swallowing
