The bottom line No known interaction

We found no known interaction between Buck's-horn Plantain and Insulin Lispro in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Additionally, although there is no interaction, the label for Insulin Lispro states a food rule worth keeping to.

Buck's-horn Plantain and Insulin Lispro

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Insulin Lispro and Buck's-horn Plantain in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Buck's-horn Plantain at all — not against Insulin Lispro, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

  • Low blood sugar Worth acting on
  • Low potassium Worth acting on
  • High blood sugar Worth acting on
  • Wheezing Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Insulin Lispro. Read the label on DailyMed › Buck's-horn Plantain’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Buck's-horn Plantain side to compare — that is a limit of the record, not a statement that Buck's-horn Plantain has no side effects.

How to take them

Some Insulin Lispro Products Have a Food Rule — Buck's-horn Plantain Should Not Break It

At least one FDA label for a product containing Insulin Lispro says to take it with food. If you take Buck's-horn Plantain on an empty stomach out of habit, keep them separate — and take Insulin Lispro with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Insulin Lispro products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2.1 , 2.2 , 2.3 , 2.4 ) Subcutaneous injection ( 2.2 ): Administer HUMALOG ® U-100 or U-200 by subcutaneous injection into the abdominal wall, thigh, upper arm, or buttocks within 15 minutes before a meal or immediately after a meal.

From the Dosage and Administration section of the FDA label we read for Insulin Lispro — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

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 Buck's-horn Plantain

What is Buck's-horn Plantain?

  • Eaten as a leafy salad green
  • Digestive complaints
  • Soothing irritated skin (topical, traditional)
  • Mild diuretic (traditional)
  • General tonic in folk medicine

Buck's-horn plantain (Plantago coronopus) is mainly a edible coastal salad green that has also been used in folk medicine for digestion and minor skin or urinary complaints. There is very little human research to support any medicinal use, so it should be viewed as a nutritious food rather than a proven remedy. If you want to use it for a health condition, talk with a pharmacist or doctor first.

Plantago coronopus · Plantaginaceae · Leaves (and sometimes seeds) · Fresh leaves (as a salad green or potherb), dried herb, tea/infusion, occasionally poultices
