From the Guidelines
For elderly patients with heart failure experiencing emesis, treatment should prioritize symptom relief while avoiding medications that could worsen heart failure, with first-line antiemetics including low-dose ondansetron or prochlorperazine, as recommended by recent guidelines 1. When managing emesis in elderly heart failure patients, it's essential to consider the potential for medications to exacerbate heart failure.
- First-line antiemetics such as low-dose ondansetron (4mg orally or IV every 8 hours) or prochlorperazine (5-10mg orally, IV, or IM every 6 hours) are preferred due to their efficacy and relatively safer profile in this population.
- Metoclopramide (5mg orally or IV every 6-8 hours) can also be effective but should be used cautiously due to potential extrapyramidal side effects, which elderly patients are more susceptible to, as noted in various studies 1.
- It's crucial to avoid medications with high sodium content or those that can cause fluid retention, such as certain formulations of promethazine, as these may exacerbate heart failure, highlighting the importance of careful medication selection and monitoring 1.
- Identifying and addressing the underlying cause of vomiting, whether it's medication-related, due to heart failure itself, or another condition, is vital for effective management.
- Ensuring proper hydration while being mindful of fluid restrictions that may be in place for heart failure management is also critical, as dehydration can worsen cardiac function and increase the risk of arrhythmias.
- Monitoring electrolytes, particularly potassium and magnesium, is essential as vomiting can deplete these and potentially worsen cardiac function or increase arrhythmia risk, as discussed in guidelines for heart failure management 1.
- If vomiting persists despite these interventions, consideration should be given to hospitalization for IV antiemetics and more intensive monitoring, especially if there are signs of decompensated heart failure or significant dehydration, emphasizing the need for prompt and aggressive management in severe cases.

Emesis Treatment for Elderly with Heart Failure
- Emesis, or nausea and vomiting, can be a symptom of various conditions, including heart failure, and can be exacerbated by certain medications 2.
- In the elderly population, heart failure is common, affecting approximately 6 to 10 percent of individuals 65 years or older, and is often accompanied by comorbid conditions such as dementia, frailty, and depression 3, 4.
- The management of heart failure in the elderly is complicated by these comorbid conditions, and a comprehensive approach to care is necessary to address these issues 4, 5.
- When it comes to treating emesis in elderly patients with heart failure, it is essential to consider the potential risks and benefits of antiemetic medications, particularly those that may prolong the QT interval or have other adverse effects 2, 6.
- For example, ondansetron, a commonly used antiemetic, has been associated with an increased risk of sudden cardiac death in certain populations, such as those receiving hemodialysis 6.
- Therefore, careful consideration of the choice of antiemetic medication is necessary in elderly patients with heart failure, taking into account their individual risk factors and comorbid conditions 2, 5.
