Interaction report

Licorice and Bumetanide

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Licorice interacts with whole categories of medication. Bumetanide falls into 3 of those categories, so it can interact with Licorice in 3 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 3

Why this applies to Bumetanide

Bumetanide falls under ANTIHYPERTENSIVE DRUGS — the group Licorice interacts with.

Theoretically, licorice might reduce the effects of antihypertensive drugs.
In human research, licorice increases blood pressure in a dose-dependent manner.
Severity Moderate Likelihood Possible Evidence B

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.

Here's the thing with licorice and your Bumetanide (Burinex). Bumetanide is a water pill that helps your body flush out extra fluid and salt. Regular licorice that still contains glycyrrhizin can push your blood pressure up and cause your body to hold onto sodium and water, which is basically working against what your water pill is trying to do. So your Bumetanide may not control swelling or fluid as well as it should.

There's another worry worth flagging. Bumetanide already lowers potassium, and licorice can lower it too. Together, that combo can drop your potassium more than expected, which may cause muscle cramps, weakness, or an irregular heartbeat. This mostly applies to real glycyrrhizin licorice taken in larger or daily amounts, not the occasional candy or DGL products. Please check with your pharmacist or doctor before mixing them.

DIURETIC DRUGS

2 of 3

Bumetanide also falls under DIURETIC DRUGS.

Theoretically, concomitant use of licorice with diuretic drugs might increase the risk of hypokalemia.
Overuse of licorice might compound diuretic-induced potassium loss. In one case report, a 72-year-old male with a past medical history of hypertension, type 2 diabetes, hyperlipidemia, arrhythmia, stroke, and hepatic dysfunction was hospitalized with severe hypokalemia and uncontrolled hypertension due to pseudohyperaldosteronism. This was thought to be provoked by concomitant daily consumption of a product containing 225 mg of glycyrrhizin, a constituent of licorice, and hydrochlorothiazide 12.5 mg for 1 month.
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 when pairing licorice with bumetanide. Bumetanide is a strong water pill, and one of its known effects is pushing potassium out through your urine. Real licorice (the kind with glycyrrhizin) does something similar in its own way, nudging your body to hold onto sodium and dump potassium. Put the two together and you can end up with low potassium, which may show up as muscle cramps, weakness, fatigue, or an irregular heartbeat.

This concern comes mostly from a single case report and theory, so it's not heavily proven, and small culinary amounts or DGL (deglycyrrhizinated) licorice are far less likely to matter than concentrated supplements taken daily. Still, before combining them, check with your pharmacist or doctor so they can keep an eye on your potassium and blood pressure.

LOOP DIURETICS

3 of 3

Bumetanide also falls under LOOP DIURETICS.

Theoretically, loop diuretics might increase the mineralocorticoid effects of licorice.
Theoretically, loop diuretics might enhance the mineralocorticoid effects of licorice by inhibiting the enzyme that converts cortisol to cortisone; however, bumetanide (Bumex) does not appear to have this effect.
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 gist for licorice and your bumetanide (Burinex). Licorice's active compound, glycyrrhizin, can make your body hold onto sodium and water and dump potassium, which is the opposite of what your water pill is trying to do. On top of that, both can push your potassium lower, so combining them may leave you feeling weak, crampy, or with an off heartbeat. Licorice can also nudge blood pressure up.

The good news: this concern is mostly theoretical, based on lab-level thinking, and bumetanide itself doesn't seem to worsen licorice's hormone effect. Everyday food or tea amounts rarely matter, but regular licorice supplements might. Don't change anything on your own, just check with your pharmacist or doctor first.

About Licorice

What is Licorice?

Licorice
  • Sore throat and cough
  • Heartburn and stomach upset
  • Mouth ulcers and digestive complaints
  • Inflammation
  • Traditional tonic/adrenal support

Licorice root is a traditional remedy used for sore throats, coughs, and digestive complaints, but solid human evidence is limited for most uses. Regular licorice contains glycyrrhizin, which can raise blood pressure and lower potassium when taken in large amounts or for a long time, so deglycyrrhizinated (DGL) products are often preferred. Talk to your pharmacist or doctor before using it, especially if you have high blood pressure, heart, or kidney problems.

About Bumetanide

What Is Bumetanide Used For?

Brand name: Burinex

Bumetanide treats edema — excess fluid that builds up in the body — caused by congestive heart failure, hepatic (liver) disease, and renal (kidney) disease, including a condition called nephrotic syndrome. This applies to the oral tablets (bumetanide and Bumex), the injection (Bumetanide Injection), and the nasal spray.

Enbumyst (bumetanide nasal spray) is specifically approved for these same uses in adults. Enbumyst is not intended for long-term use and should be switched to an oral diuretic as soon as practical.
