Drug & supplement interaction

Wood Sorrel + Ertapenem

Ertapenem brand name: Invanz.

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 Wood Sorrel and Ertapenem 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 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.

Wood Sorrel and Ertapenem

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 Ertapenem and Wood Sorrel 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 Wood Sorrel at all — not against Ertapenem, 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.

What to actually watch for

No Interaction Found — But Data Suggests Wood Sorrel and Ertapenem 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.

From our pharmacist’s overview on the Ertapenem page

“Ertapenem (Invanz) is a potent injectable antibiotic used for serious infections, and with one major-rated interaction among the 50 ingredients here, this is a list to read carefully rather than skim. The major entry is activated charcoal, which can pull down levels of many drugs even when they are not swallowed, so it can matter despi…”

About Wood Sorrel

What is Wood Sorrel?

  • Digestive upset
  • Mouth and throat soothing
  • Mild diuretic
  • Fever and thirst relief
  • Wound and skin care (traditional)

Wood sorrel is a small, sour-tasting wild plant used in folk medicine and as a tangy edible green. There is very little modern research to support any health use, and its naturally high oxalic acid content means it should be used in small amounts. People with kidney problems, gout, or who are pregnant should be especially cautious.

Oxalis acetosella · Oxalidaceae · Leaves and aerial parts · Fresh leaves, tea, tincture, juice

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

Wood Sorrel: dosing

There is no established or standardized medicinal dose for wood sorrel. It has been used traditionally as fresh leaves, a tea, or a juice, but no reliable guidelines exist for how much is safe or effective.Because of its oxalic acid content, it is wise to keep any use to small amounts and avoid taking it regularly.

About Ertapenem Injection

Taking Wood Sorrel and Ertapenem Together: Common Questions

Is it safe to take Wood Sorrel with Ertapenem?

Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other.
