What is Aloxi?
Aloxi (palonosetron) blocks the actions of chemicals in the body that can trigger nausea and vomiting.
Aloxi is used in adults to prevent nausea and vomiting caused by surgery, or by receiving medicine to treat cancer (chemotherapy).
Aloxi is used in children as young as 1 month old only to prevent nausea and vomiting caused by cancer medicine.
Before you receive Aloxi, tell your doctor about all your medical conditions or allergies, and all the medicines you are using. Also make sure your doctor knows if you are pregnant or breast-feeding.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
Tell your doctor if you forget to take use Aloxi within 1 hour before chemotherapy. Do not use extra medicine to make up the missed dose.
Before receiving this medicine
You should not be treated with Aloxi if you are allergic to palonosetron.
To make sure Aloxi is safe for you, tell your doctor if you have ever had an allergic reaction to a similar medicine for nausea or vomiting, such as dolasetron (Anzemet) or ondansetron (Zofran).
Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. These medicines may interact with palonosetron and cause a serious condition called serotonin syndrome.
Tell your doctor if you are pregnant or breast-feeding.
How is Aloxi given?
Aloxi is injected into a vein through an IV. A healthcare provider will give you this injection.
Aloxi is usually given 30 minutes before chemotherapy, or right before you are given anesthesia for surgery.
