  • People who are pregnant, breastfeeding, or planning to become pregnant during the study.
  • People with certain serious physical health conditions, including untreated epilepsy with a history of major (grand-mal) seizures, a history of delirium, severe heart failure, untreated or poorly controlled high blood pressure, chest pain (angina), severe liver disease, severely reduced kidney function, or other conditions the investigators judge to carry too great a risk of side effects.
  • People who are unable to follow study procedures due to language barriers, psychological difficulties, dementia, or similar reasons.
