Khella and Glyburide

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

Why Are There 2 Interactions?

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

Moderate

PHOTOSENSITIZING DRUGS

1 of 2

Why this applies to Glyburide

Glyburide falls under PHOTOSENSITIZING DRUGS — the group Khella interacts with.

Theoretically, concomitant use might result in increased photosensitivity. Khella constituents can cause photosensitivity. Some drugs that cause photosensitivity include amitriptyline (Elavil), quinolones (Ciprofloxacin, others), sulfa drugs (Septra, Bactrim, others), and tetracycline.
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 know if you're pairing khella with glyburide: this isn't about your blood sugar control or how the drug is broken down. The concern is purely about your skin. Khella contains compounds (like khellin) that can make your skin more sensitive to sunlight, and glyburide already carries its own mild tendency to do the same. Put them together and you might sunburn faster or more easily than you'd expect.

I'll be honest, this is theoretical and based only on anecdotal reports, so it's not a strong warning. It won't change how well your diabetes is managed. If you do use both, just be smart about sun protection (sunscreen, a hat, shade) and check with your pharmacist or doctor first.

HEPATOTOXIC DRUGS

2 of 2

Glyburide also falls under HEPATOTOXIC DRUGS.

Theoretically, khella might have additive adverse effects on the liver when used with hepatotoxic drugs. Khella can increase liver transaminases. Some drugs that can adversely affect the liver include acetaminophen (Tylenol), amiodarone (Cordarone), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), methyldopa (Aldomet), and many others.
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.

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

Here's the gist with glyburide and khella: this isn't about your blood sugar control directly. Instead, the concern is your liver. Glyburide is processed by the liver and, like many diabetes medicines, it can occasionally nudge your liver enzymes up. Khella has been shown to raise those same liver enzymes (transaminases) too. Stack the two together and the worry is that the strain on your liver could add up.

To be honest, this is mostly a theoretical caution, not something proven to happen often. Still, watch for warning signs like yellowing skin or eyes, dark urine, belly pain, or unusual tiredness. Before adding khella, check with your pharmacist or doctor, who may want to keep an eye on your liver labs.

About Glyburide

What Is Glyburide Used For?

Brand names: Diabeta, Micronase, Glynase, Glycron, Micronized, Glynase PresTab, Albert Glyburide

Glyburide tablets are used alongside diet and exercise to help control blood sugar in adults with type 2 diabetes. It is not for type 1 diabetes or diabetic ketoacidosis (a serious complication where the body produces dangerous levels of acids called ketones).

Glyburide may be used alone or combined with metformin when metformin alone is not enough. It can also be used to help transition patients who are moving from insulin or other diabetes pills to a new regimen, under a doctor's guidance.
