Drug & supplement interaction

Eastern Red Cedar + 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 Eastern Red Cedar 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.

Interaction report

Eastern Red Cedar 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 Eastern Red Cedar 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.

What to actually watch for

No Interaction Found — But Data Suggests Eastern Red Cedar 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.

  • An allergic reaction Worth acting on Additional detail

    “Orally, overdose of Eastern red cedar oil might cause burning in the stomach, vomiting, convulsions, coma, and death (12). Topically, Eastern red cedar oil might cause local allergic reactions and irritation; however, several clinical assessments of safety show that applying Eastern red cedar oil topically does not cause skin sensitization or irritation (11,98802).”

How to take them

Some Alogliptin, Metformin Products Have a Food Rule — Eastern Red Cedar Should Not Break It

At least one FDA label for a product containing Alogliptin, Metformin says to take it with food. If you take Eastern Red Cedar 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 Eastern Red Cedar

What is Eastern Red Cedar?

  • Insect repellent
  • Aromatherapy and relaxation
  • Skin and minor wound care (topical, traditional)
  • Respiratory or congestion relief (traditional)
  • Antimicrobial and antifungal (lab-based interest)

Eastern Red Cedar is a North American evergreen tree whose wood and aromatic oil have long been used for fragrance, insect repelling, and folk remedies. Solid human research on its health benefits is very limited, and the essential oil can be toxic if swallowed, so it is mainly used externally or for aroma. Talk to a pharmacist or doctor before using it, especially during pregnancy or breastfeeding.

Juniperus virginiana · Cupressaceae · Leaves (needles), wood, berry-like cones, and essential oil · Essential oil, dried leaf, wood shavings/sachets, tinctures, and topical preparations

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

Eastern Red Cedar: dosing

There is no established, standardized medicinal dose for Eastern Red Cedar. It is not a well-studied oral supplement, and the essential oil is not meant to be taken by mouth.For aromatherapy or topical use, follow the directions on the specific product label and always dilute the essential oil in a carrier oil before applying to skin.
