Drug & supplement interaction

Shepherd's Purse + Insulin Glulisine (rDNA)

Insulin Glulisine (rDNA) brand name: Apidra.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Shepherd's Purse and Insulin Glulisine (rDNA) in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Shepherd's Purse and Insulin Glulisine (rDNA)

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 Glulisine (rDNA) and Shepherd's Purse 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.

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.

How we checked

Why No Interaction Is Listed for Insulin Glulisine (rDNA)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Insulin Glulisine (rDNA) is filed under a single classification — antidiabetes drugs. Shepherd's Purse has documented interactions with 2 drug classes — the most serious being cns depressants (moderate) and thyroid hormone (moderate) — and none of Insulin Glulisine (rDNA)’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Shepherd's Purse and Insulin Glulisine (rDNA) May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

About Shepherd's Purse

What is Shepherd's Purse?

Shepherd's Purse
  • Heavy or prolonged menstrual bleeding
  • Minor bleeding (nosebleeds, wounds)
  • Mild diuretic
  • Digestive complaints
  • After-childbirth bleeding (traditional)

Shepherd's purse is a traditional herb most often used to help slow heavy menstrual bleeding and other minor bleeding, but solid human research is very limited. Because it may affect blood clotting, blood pressure, and the uterus, it should be avoided during pregnancy and used cautiously under professional guidance.

Capsella bursa-pastoris · Brassicaceae · Above-ground parts (leaves, stems, flowers, and seed pods) · Tea, liquid extract/tincture, dried herb, capsules

An interaction check asks whether these two react with each other — it does not ask whether Shepherd's Purse is a good idea for someone in your situation. Here is what our Shepherd's Purse record says about it on its own.

Shepherd's Purse: dosing

There is no official, standardized dose for shepherd's purse. The right amount can vary by product, form (tea, tincture, or capsule), and how concentrated it is.The safest approach is to follow the directions on the product label and not exceed them.

Is it safe to take Shepherd's Purse with Insulin Glulisine (rDNA)?
