Chervil + Metformin, Sitagliptin
Metformin, Sitagliptin brand names: Janumet, Janumet XR.
We found no known interaction between Chervil and Metformin, Sitagliptin 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 Metformin, Sitagliptin states a food rule worth keeping to.
Chervil and Metformin, Sitagliptin
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 Metformin, Sitagliptin and Chervil 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 Chervil at all — not against Metformin, Sitagliptin, 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.

Some Metformin, Sitagliptin Products Have a Food Rule — Chervil Should Not Break It
At least one FDA label for a product containing Metformin, Sitagliptin says to take it with food. If you take Chervil on an empty stomach out of habit, keep them separate — and take Metformin, Sitagliptin 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 Metformin, Sitagliptin 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 DOSAGE AND ADMINISTRATION Take sitagliptin and metformin hydrochloride extended-release tablets orally once daily with a meal.

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 Chervil
What is Chervil?
- Digestive upset
- Mild fluid retention (diuretic)
- Skin and eye compresses (traditional)
- Culinary seasoning
- General 'spring tonic' or cleansing
Chervil is a delicate culinary herb in the carrot and parsley family that has long been used in folk medicine for digestion and as a mild diuretic. There is very little modern scientific research to confirm any health benefit, so it is best thought of as a flavorful food rather than a proven remedy. It is generally regarded as safe in food amounts, but concentrated supplements and the essential oil are not well studied.
Anthriscus cerefolium · Apiaceae · Leaves (fresh or dried) and aerial parts · Fresh or dried herb, tea (infusion), juice, and occasionally essential oil
An interaction check asks whether these two react with each other — it does not ask whether Chervil is a good idea for someone in your situation. Here is what our Chervil record says about it on its own.
