Drug & supplement interaction

American Mistletoe + Alogliptin, Metformin

Alogliptin, Metformin brand name: Kazano.

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 American Mistletoe and Alogliptin, Metformin 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 label for Alogliptin, Metformin states a food rule worth keeping to, and 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.

American Mistletoe and Alogliptin, Metformin

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 Alogliptin, Metformin and American Mistletoe 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 Alogliptin, Metformin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alogliptin, Metformin is filed under 4 classifications — including organic cation transporter 2 (oct2) substrates, antidiabetes drugs, oral drugs. American Mistletoe has documented interactions with 2 drug classes — the most serious being antihypertensive drugs (major) and vasodilators (major) — and none of Alogliptin, Metformin’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 American Mistletoe and Alogliptin, Metformin May Share Several of the Same Side Effects

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.

  • Raised blood pressure Worth acting on Additional detail

How to take them

Some Alogliptin, Metformin Products Have a Food Rule — American Mistletoe Should Not Break It

At least one FDA label for a product containing Alogliptin, Metformin says to take it with food. If you take American Mistletoe on an empty stomach out of habit, keep them separate — and take Alogliptin, Metformin 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 Alogliptin, Metformin 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 ) Given orally twice daily with food.

From the Dosage and Administration section of the FDA label we read for Alogliptin, Metformin — 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 Alogliptin, Metformin page

“Kazano combines alogliptin and metformin to lower blood sugar, and nearly everything on this list pushes on that same lever, so I treat these pairings with real caution. Most entries are herbs and supplements that lower glucose on their own, and stacked on the drug they raise the risk of hypoglycemia, a sugar drop steep enough to cause…”

About American Mistletoe

What is American Mistletoe?

American Mistletoe
  • Traditional folk remedies
  • Digestive complaints
  • Decorative holiday plant

American mistletoe is a parasitic plant that is best known as a holiday decoration, not a proven medicine. It contains toxins that can harm the heart, gut, and blood vessels, and it has little reliable evidence to support any health use. We do not recommend taking it, and all parts should be kept away from children and pets.

Phoradendron leucarpum · Santalaceae · Leaves, stems, and berries · Rarely used as a supplement; historically as tea or dried plant. Most often seen as a holiday decoration.

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

American Mistletoe: dosing

There is no established safe or effective dose of American mistletoe. Because the plant is toxic and not recommended for medicinal use, no dosing guidance can be given.If you ever see a product containing mistletoe, do not take it without first speaking to a pharmacist or doctor. The safest approach is to avoid using American mistletoe internally altogether.
