Atlantic Cedar and Empagliflozin, 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 Empagliflozin, Metformin and Atlantic 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Atlantic Cedar at all — not against Empagliflozin, Metformin, 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.

How to take them

Some Empagliflozin, Metformin Products Have a Food Rule — Atlantic Cedar Should Not Break It

At least one FDA label for a product containing Empagliflozin, Metformin says to take it with food. If you take Atlantic Cedar on an empty stomach out of habit, keep them separate — and take Empagliflozin, 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 Empagliflozin, 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.

( 2.2 , 2.3 ) SYNJARDY XR: take orally once daily with a meal in the morning, with gradual dosage escalation to reduce the gastrointestinal adverse reactions due to metformin HCl.

From the Dosage and Administration section of the FDA label we read for Empagliflozin, 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.

About Atlantic Cedar

What is Atlantic Cedar?

Atlantic Cedar
  • Hair loss (alopecia areata)
  • Insect repellent
  • Antimicrobial and antifungal
  • Aromatherapy and relaxation
  • Fragrance in cosmetics and perfumes

Atlantic cedar (Cedrus atlantica) is a tree whose wood and essential oil are used in traditional medicine, mainly applied to the skin and scalp or used as a scent. Human evidence for its health benefits is very limited, and the oil should be used diluted and never swallowed. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or treating a child.

There is no established standard dose for Atlantic cedar. It is not meant to be taken by mouth, and most use is topical or as a scent.If you use a product containing the oil, follow the directions on the label and dilute the essential oil in a carrier oil before applying it to skin.
