This study is about comparing two ways to stop nausea (feeling sick) and vomiting (throwing up) during chemotherapy for pancreatic cancer. One way uses auricular point stimulation (a type of acupuncture where tiny seeds are stuck on the ear) with a medicine called dexamethasone. The other way is a standard medicine treatment doctors usually use. The chemotherapy uses two drugs, gemcitabine and paclitaxel protein-bound, which can cause nausea and vomiting.

Participants will be split into two groups. One group will receive ear acupressure and dexamethasone, and the other group will get the standard medicine treatment. Both groups will track their nausea, vomiting, appetite, and digestion from Day 1 to Day 5 of their chemotherapy cycle.

• Study Length: Participants will need to monitor and record symptoms for 5 days during each chemotherapy cycle.
• Commitment: Participants will apply ear seeds daily and record symptoms.
• Potential Benefit: The study may help find a better way to manage nausea and improve patients' quality of life.
