There are more than 100 different medicines used in cancer treatment (chemotherapy). These drugs have been ranked by how often they cause nausea and vomiting.¹ Here's a sampling of common cancer drugs and their risk for causing nausea and vomiting.

A few cancer drugs are on the list more than once. That's because the size of the dose of a cancer drug can change its chances of making you sick.

Some drugs are highly likely to cause nausea and vomiting. The drugs in this group cause nausea and vomiting in more than 9 out of 10 people who take them. These include:

• Moderate- to high-dose cisplatin.
• High-dose carmustine or cyclophosphamide.
• Dacarbazine.
• Mechlorethamine.
• Streptozocin or cyclophosphamide (with or without doxorubicin or epirubicin).

Other drugs are likely to cause nausea and vomiting. The drugs in this group cause nausea and vomiting in 6 to 9 out of 10 people who take them. They include:

• High-dose amifostine, busulfan, cytarabine, doxorubicin, epirubicin, melphalan, or methotrexate.
• Moderate-dose cyclophosphamide.
• Carboplatin.
• Carmustine.
• Cisplatin.
• Dactinomycin.
• Procarbazine (as a pill).

Another group of drugs is only somewhat likely to make you feel sick. Between 3 to 6 out of 10 people get sick with these medicines. They include:

• Moderate-dose amifostine and moderate- to high-dose methotrexate.
• Arsenic trioxide.
• Cyclophosphamide.
• Doxorubicin, epirubicin, and idarubicin.
• Hexamethylmelamine (as a pill).
• Ifosfamide.
• Interleukin-2.
• Irinotecan.
• Lomustine.
• Mitoxantrone.
• Oxaliplatin.

Talk with your doctor about the cancer drug you will be given and your chances of getting sick from it. Discuss your treatment options for nausea and vomiting with your doctor before you start chemotherapy.
