HTN: Food/Nutrient and Medication Interaction Assessment
Dietitians should assess food/nutrient-medication interactions in patients that are on pharmacologic therapy for hypertension, as many antihypertensive medications interact with food and nutrients.
Risks/Harms of Implementing This Recommendation
Adverse side effects and potential drug-nutrient interactions may be observed in some patients receiving pharmacologic therapy.
Conditions of Application
Medications may be contraindicated or poorly tolerated in some individuals.
Potential Costs Associated with Application
- Based on the JNC 7 report, although blood pressure control can be achieved in most patients who are hypertensive, many will require two or more antihypertensive medications.
- Based on the JNC 7 report, failure to comply with lifestyle modifications and pharmacotherapy may result in inadequate blood pressure control.
Recommendation Strength Rationale
The ADA Hypertension Expert Work Group concurs with the recommendations from the JNC 7, regarding food/nutrient and medication interactions.
