Corn Silk and Enalapril Maleate, Hydrochlorothiazide

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Corn Silk interacts with whole categories of medication. Enalapril Maleate, Hydrochlorothiazide falls into 2 of those categories, so it can interact with Corn Silk in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTIHYPERTENSIVE DRUGS

1 of 2

Why this applies to Enalapril Maleate, Hydrochlorothiazide

Enalapril Maleate, Hydrochlorothiazide falls under ANTIHYPERTENSIVE DRUGS — the group Corn Silk interacts with.

Taking corn silk extract with antihypertensive drugs might increase the risk of hypotension.
Clinical research in both hypertensive and normotensive adults shows that taking corn silk extract lowers systolic and diastolic blood pressure.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to keep in mind with Vaseretic (enalapril plus hydrochlorothiazide): it already does two jobs to lower your blood pressure, relaxing your vessels and pulling off extra fluid through your urine. Corn silk seems to have a mild blood pressure lowering effect of its own, so pairing the two could nudge your numbers down a little more than expected.

If your pressure drops too low, you might feel dizzy or lightheaded, especially when you stand up, and you could feel tired or weak. Since the water pill part already makes you lose fluid, that effect could add up. To be honest, this is a theoretical concern based on how things work, not strong proof. Still, mention it to your pharmacist or doctor before adding corn silk, and don't change your medication on your own.

DIURETIC DRUGS

2 of 2

Enalapril Maleate, Hydrochlorothiazide also falls under DIURETIC DRUGS.

Taking corn silk with diuretic drugs might increase the risk of adverse effects such as hyponatremia and hypokalemia.
Clinical research shows that taking corn silk extract increases urine volume and promotes the urinary excretion of sodium and potassium. Some patients may require electrolyte supplementation.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

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

Here's the thing with Vaseretic: it already contains hydrochlorothiazide, a true 'water pill' that flushes out extra fluid along with sodium and potassium. Corn silk seems to nudge your body in the same direction, making you urinate more and lose more of those same electrolytes. So you're not really getting two different effects, you're potentially doubling up on one.

If your sodium or potassium dips too low, you might notice things like dizziness, muscle cramps, weakness, headache, or feeling lightheaded when you stand up. To be fair, this concern is based on how corn silk works rather than strong human studies, so it's more of a 'be aware' than a 'panic' situation. Still, since you're already on a diuretic, I'd run it by your pharmacist or doctor first, and they may want to check your electrolytes.

About Corn Silk

What is Corn Silk?

Corn Silk
  • Urinary tract and bladder problems
  • Mild fluid retention (diuretic)
  • Kidney and prostate concerns
  • Bedwetting in children
  • Soothing urinary irritation

Corn silk is a traditional herbal remedy taken as a tea or extract, mostly for urinary and mild fluid-related complaints. High-quality human evidence for these uses is limited, so it should not replace proven treatments. It is generally considered low-risk for short-term use in healthy adults, but talk with your pharmacist or doctor before trying it.

About Enalapril and Hydrochlorothiazide

What Is Enalapril and Hydrochlorothiazide Used For?

Brand name: Vaseretic

Enalapril and hydrochlorothiazide tablets — sold under brand names including Vaseretic and Enalapril maleate and hydrochlorothiazide — are used to treat high blood pressure (hypertension). This combination is not meant as the first treatment tried; it's generally used when a single blood pressure medicine hasn't done the job on its own.

Because this is a fixed-dose combination, your doctor will typically adjust each medicine separately first, then switch you to the combination tablet once the right doses are found.
