Will my chemotherapy make me sick?

Without receiving special anti-nausea medications, most patients will experience some nausea after treatment with chemotherapy. Nausea and vomiting may last 24-48 hours. The severity of nausea and vomiting mainly depends on which chemotherapy drugs were used. A number of very effective medications called anti-emetics or anti-nausea drugs are now available to help lessen or prevent nausea and vomiting. These medications may be given to you intravenously during your chemotherapy, or you may be given a prescription medication to take at home.
