SUSTOL can help prevent nausea and vomiting due to chemotherapy (CINV) for a full 5 days

SUSTOL is a medicine called an antiemetic that may help prevent these side effects1,2

Some antiemetics may fail after just a few days. Because of the unique formulation of SUSTOL, one injection can protect you from chemotherapy side effects for a full 5 days. Based on the type of chemotherapy you have, your doctor may choose SUSTOL as the best option for you. If you have any questions about SUSTOL, ask your healthcare provider.
