This study checks if taking KarXT, a medicine for mental health issues like schizophrenia, with anti-nausea drugs helps reduce feeling sick and throwing up. KarXT can make your stomach upset, especially at first. The study is for healthy people who will try taking KarXT with medicine that helps stop nausea, either regularly or when needed. The aim is to find out which way works best and is safest.

Key Points:

• 3-week stay: Participants must stay at the study place for 3 weeks.
• Eligibility: You must be healthy with no major illnesses and willing to follow study rules.
• Risks: People with certain health conditions cannot join. Discuss with a doctor to see if you qualify.

This study will help doctors figure out how to make starting KarXT easier for patients by managing side effects better.
