Apple and Valsartan

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Valsartan

Valsartan falls under ANTIHYPERTENSIVE DRUGS — the group Apple interacts with.

Consuming apple juice with antihypertensive drugs might interfere with blood pressure control.
Some clinical evidence suggests that consuming apple and cherry juice can increase blood pressure in elderly patients.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for valsartan (Diovan): eating a regular apple as part of your diet is not the concern here. The signal in the research is about drinking apple juice, often in larger amounts, alongside blood pressure medicines. Some lower quality studies in older adults suggest that apple and cherry juice may nudge blood pressure upward, which could work against what valsartan is trying to do.

In plain terms, your readings might run a little higher than expected, so your medicine may not control your pressure as smoothly. This evidence isn't rock solid, so don't panic or change anything on your own. If you drink apple juice often, just mention it to your pharmacist or doctor and keep an eye on your home blood pressure numbers.

About Apple

What is Apple?

Apple
  • General nutrition and fiber intake
  • Heart and cholesterol health
  • Blood sugar and weight management
  • Digestive regularity
  • Antioxidant support

Apples are a nutritious whole food that provides fiber, vitamins, and antioxidant plant compounds, and eating them regularly fits well into a healthy diet. While research suggests apples may support heart and digestive health, most claims about concentrated apple supplements or extracts are not strongly proven, so enjoy apples as food and talk with your pharmacist before using high-dose products.

About Valsartan

Valsartan oral solution is specifically indicated for patients with heart failure or post-heart attack left ventricular dysfunction who are unable to swallow tablets.
