There are multiple potential states and/or symptoms that may occur in the palliative care population including: pain, nausea/vomiting, fatigue, anorexia, dyspnea, hiccups, cough, constipation, abdominal cramps/bloating, diarrhea, pruritis, depression/anxiety, dysphagia and sleep disturbances. Some of this may be the direct result of medications or drug-drug interactions from agents prescribed to treat the medical conditions that the patient has. Medication-related nausea and vomiting (MRNV) is a significant problem in palliative medicine that is reasonably common likely due to the multiple medications that these patients are often taking.
