Zofran is probably the best anti-nausea medicine I took throughout my treatment. Phenergan works really well at night and also helps you to sleep. It can be taken with zofran because they're different types of medicine. Another good one is Emend. You would take this before you started treatment and it helps to reduce nausea for up to 5 days following. There are a couple of ways Emend can be taken. If your insurance will approve it, Emend is a good medicine to take.
Good Luck with your treatment - Jimmy
