ANTIDIABETES DRUGS

Why this applies to Insulin Lispro Recombinant

Insulin Lispro Recombinant falls under ANTIDIABETES DRUGS — the group Solomon's Seal interacts with.

Theoretically, concomitant use may enhance hypoglycemic drug effects and alter blood glucose control. Monitor blood glucose.
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 practical picture with Humalog (insulin lispro). This insulin is a fast-acting medicine you inject to bring your blood sugar down at mealtimes. The concern with Solomon's Seal is that it might have a mild blood-sugar-lowering effect of its own. If that's true, adding it on top of your insulin could push your sugar lower than expected, which means more risk of hypoglycemia: shakiness, sweating, dizziness, fast heartbeat, confusion, or feeling faint.

I want to be honest about how weak this is. It's a theoretical idea based on lab and animal compounds, not real human studies, so for most people it likely won't cause problems. Still, if you decide to try it, check your blood sugar a bit more closely at first and loop in your doctor or pharmacist before changing anything.

Insulin dosage adjustments may be necessary, due to the possible hypoglycemic effects of Solomon's seal.
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: Humalog (insulin lispro) is a fast-acting mealtime insulin that lowers your blood sugar. Solomon's Seal may have its own mild blood-sugar-lowering effect, at least based on lab and animal work. If both are working in the same direction, the worry is that your sugar could drop too low. That can show up as shakiness, sweating, a racing heart, confusion, or feeling lightheaded.

I want to be honest about the strength of this, though. It's theoretical, pulled from pharmacology rather than solid human studies, so for many people it may never cause a problem. Still, since insulin doses are tight, it's worth a quick chat with your pharmacist or doctor before adding the herb, and keep an eye on your readings if you do.

  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction 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.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

See Every Supplement That Interacts With Insulin Lispro Recombinant

This page covers Solomon's Seal only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Insulin Lispro Recombinant page lists 242 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Chelation Therapy Products (major), Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate) and Agaricus Mushroom (moderate).

By severity: 2 major · 211 moderate · 29 minor.

From our pharmacist’s overview on the Insulin Lispro Recombinant page

“Two of the 242 entries here rate major, and they are the place to start. Siberian cocklebur has caused severe hypoglycemia, and chelation products containing EDTA can drop blood glucose steeply while also interfering with the insulin itself, so neither belongs anywhere near insulin lispro (Humalog KwikPen).”
