Lots of anti-nausea options, along with Zofran (Ondansentron), including Aloxi, steroids (dexamethasone), Compazine (Prochlorperazine), CBD, medical marijuana, Marinol (FDA approved synthetic THC -- i.e., "medical marijuana that's legal in all 50 states).

If the reaction feels like it's more reflux/heartburn in the upper GI (esophagus), ask a GI or palliative doc about meds specific to that, but doublecheck any of them with an oncology-informed pharmacist to avoid any bad interactions.

Hang in there!
