Veronica and Glipizide, 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 Glipizide, Metformin and Veronica 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 Veronica at all — not against Glipizide, 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.

  • Low blood sugar Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Raised blood pressure Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Glipizide, Metformin. Read the label on DailyMed › Veronica’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Veronica side to compare — that is a limit of the record, not a statement that Veronica has no side effects.

How to take them

Some Glipizide, Metformin Products Have a Food Rule — Veronica Should Not Break It

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

Glipizide and Metformin Hydrochloride Tablets in Patients with Inadequate Glycemic Control on Diet and Exercise Alone For patients with type 2 diabetes whose hyperglycemia cannot be satisfactorily managed with diet and exercise alone, the recommended starting dose of glipizide and metformin hydrochloride tablets are 2.5 mg/250 mg once a day with a meal.

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

“Glipizide and metformin (Metaglip) already work hard to pull blood sugar down, which is exactly why this list of 307 ingredients deserves genuine vigilance rather than a shrug. Most of them, 239, can lower glucose on their own, and stacked on this pill the combined effect can tip into true hypoglycemia.”

About Veronica

What is Veronica?

Veronica
  • Coughs and respiratory complaints
  • Digestive upset and appetite stimulation
  • Gout, arthritis, and rheumatic complaints
  • Kidney and urinary tract conditions
  • Mouth and throat inflammation (topical)

Veronica (speedwell) is a traditional European herb used mainly for coughs, digestive complaints, and joint problems, but there is very little modern scientific evidence to show it actually works for any of these. It is generally considered mild, but its safety has not been well studied, so check with a pharmacist or doctor before using it — and avoid it during pregnancy and breastfeeding.

Veronica officinalis · Plantaginaceae · Above-ground (aerial) parts — the flowering herb, including leaves and stems · Tea (infusion), tincture, dried herb, and topical rinses or gargles

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

Veronica: dosing

There is no standardized or scientifically established dose for Veronica. Traditional use has mostly involved a tea made from the dried herb or a tincture, but exact safe and effective amounts have not been determined by research.If you use a commercial product, follow the directions on the label and do not exceed the recommended amount.
