Quercetin and Dasiglucagon Hydrochloride

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Dasiglucagon Hydrochloride

Dasiglucagon Hydrochloride falls under ANTIDIABETES DRUGS — the group Quercetin interacts with.

Theoretically, concomitant use of quercetin and antidiabetes drugs might increase the risk of hypoglycemia.

Clinical research suggests that a combination of quercetin, myricetin, and chlorogenic acid reduce levels of fasting glucose in patients with type 2 diabetes, including those already taking antidiabetes agents. The effect of quercetin alone is unknown.
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 something worth knowing about this pairing, though it's mostly theoretical. Quercetin may have a mild blood-sugar-lowering effect on its own, and the concern on file is that combining it with diabetes medicines could nudge blood sugar a little lower than expected. The evidence is limited, and most of it comes from quercetin mixed with other plant compounds, not quercetin by itself.

Now, dasiglucagon (Zegalogue) is actually a bit of an odd fit here. It does the opposite of most diabetes drugs: it's a rescue shot that raises blood sugar fast during a severe low. Quercetin doesn't really block how it works. In practice, this interaction matters far more for your daily diabetes medicines than for an emergency glucagon pen. Still, mention any supplements to your pharmacist or doctor so they can keep an eye on your overall control.

“Dasiglucagon (Zegalogue) is an emergency injection that rapidly raises blood sugar during a severe diabetic low, so a supplement list this large deserves genuine care. All 239 interacting ingredients act through blood glucose, and most of them lower it, deepening the very crashes this drug exists to reverse.”

About Quercetin

What is Quercetin?

Quercetin

Quercetin is a plant flavonoid with antioxidant and anti-inflammatory properties found in many common foods and sold as a supplement.

It is generally well tolerated in food amounts, but talk to your pharmacist or doctor before taking high-dose supplements.
