Pata De Vaca and Insulin Lispro

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin Lispro

Insulin Lispro falls under ANTIDIABETES DRUGS — the group Pata De Vaca interacts with.

Animal research suggests that pata de vaca may have hypoglycemic effects. However, preliminary clinical research shows that pata de vaca does not reduce blood glucose levels. Until more is known, use with caution. Theoretically, concomitant use of pata de vaca with antidiabetes drugs might affect glucose control and increase the risk of hypoglycemia. Dose adjustments to diabetes medications might be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.
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 simple version: Insulin lispro is a fast-acting mealtime insulin that already lowers your blood sugar. Pata de vaca is traditionally used to nudge blood sugar down too. If both push in the same direction, the worry is that they could lower your sugar a little too much, which we call hypoglycemia. With a rapid insulin like lispro, that can show up as shakiness, sweating, a racing heart, confusion, or feeling dizzy.

I'll be honest with you, this concern is mostly theoretical. Animal studies hint at a blood-sugar effect, but early human research didn't really show one. So I'm not telling you to avoid it, just to be aware. If you do try it, check your sugars more closely and let your pharmacist or doctor know before any insulin dose is changed.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • 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.

From our pharmacist’s overview on the Insulin Lispro page

“Blood sugar is the entire subject of this list. Insulin lispro (Admelog) is a rapid mealtime insulin dosed to bring glucose down after eating, and the supplements below can shove that same number around, most of them downward, which risks a genuine low.”

About Pata De Vaca

What is Pata De Vaca?

  • Blood sugar support
  • Diabetes (traditional use)
  • Diuretic
  • Kidney and urinary health
  • General tonic

Pata de Vaca is a South American plant whose leaves are traditionally brewed as a tea to help support blood sugar, earning it the nickname 'vegetable insulin.' Human evidence is very limited, so it should not replace prescribed diabetes treatment. Talk to your pharmacist or doctor before using it, especially if you take blood-sugar medications.

About Insulin Lispro Injection

What Is Insulin Lispro Injection Used For?

Brand names: Admelog, Admelog Solostar

Insulin lispro injection is used to improve glycemic control (blood sugar management) in people with diabetes mellitus. It is a rapid-acting insulin analog approved for use in both type 1 and type 2 diabetes.

Admelog is specifically indicated to improve glycemic control in patients with diabetes mellitus. Humalog Mix75/25 is indicated to improve glycemic control in adults with diabetes mellitus; it is a fixed-ratio mixture of insulin lispro and insulin lispro protamine, and its fixed proportions do not allow for separate adjustment of basal (background) and prandial (mealtime) doses.
