Water Avens and Isotretinoin

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 Isotretinoin and Water Avens 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 Water Avens at all — not against Isotretinoin, 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 Isotretinoin’s Own FDA Label Lists

This is not an interaction — none of it involves Water Avens. These are the most notable effects listed in the ADVERSE REACTIONS section of Isotretinoin’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Thoughts of self-harm Worth acting on mentioned in 4.5% of FDA reports for Isotretinoin
  • Low mood Worth acting on mentioned in 12.1% of FDA reports for Isotretinoin
  • Bone thinning Worth acting on
  • Severe muscle breakdown Worth acting on
  • Hallucinations Worth acting on
  • Pancreatitis Worth acting on
  • Fainting Worth acting on
  • Wheezing Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on

Showing the 10 most notable of 56 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Isotretinoin. Read the label on DailyMed › Where a percentage is shown, it is the share of 46,523 voluntary FDA FAERS reports for Isotretinoin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Water Avens’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Water Avens side to compare — that is a limit of the record, not a statement that Water Avens has no side effects.

Everything else you take

See Every Supplement That Interacts With Isotretinoin

This page covers Water Avens only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Isotretinoin page lists 49 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Vitamin A (major), African Wild Potato (moderate), Alfalfa (moderate) and Angelica Archangelica (moderate).

By severity: 2 major · 35 moderate · 12 minor.

From our pharmacist’s overview on the Isotretinoin page

“Vitamin A is the first thing anyone on isotretinoin (Accutane, Absorica, Claravis) should check their supplements for, because isotretinoin is itself a vitamin A derivative and stacking more on top can push levels into toxic range. It is one of two major-rated entries among the 49 supplements and herbs known to interact with this acne…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Water Avens is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Water Avens reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 27, 2026. The Water Avens and Isotretinoin records this page draws on were last updated July 11, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Water Avens

What is Water Avens?

  • Diarrhea and digestive upset
  • Sore throat and mouth irritation
  • Mild fever
  • General tonic
  • Astringent for minor wounds

Water avens is a traditional herb whose root has been used as an astringent for diarrhea, sore throats, and digestive complaints. There is very little modern scientific research to confirm that it works or to define a safe dose, so use it cautiously and talk with a pharmacist or doctor first.

Geum rivale · Rosaceae · Root and rhizome (occasionally aerial parts) · Dried root, tea/decoction, tincture

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

Water Avens: dosing

There is no established or standardized dose for water avens. Traditional use involved teas (decoctions) of the dried root or tinctures, but reliable, research-based dosing is not available.If you choose to use a product, follow the directions on the label and do not exceed them.

About Isotretinoin

What Is Isotretinoin Used For?

Brand names: Accutane, Amnesteem, Claravis, Sotret, Absorica, Roaccutane

Isotretinoin capsules — sold under brand names including Absorica, Absorica LD, Accutane, Amnesteem, Claravis, and others — are used to treat severe recalcitrant nodular acne (deep, inflamed acne nodules 5 mm or larger) in non-pregnant patients 12 years of age and older whose acne has not responded to conventional treatments, including systemic antibiotics.

This medication is reserved for serious cases — those with many nodules, not just a few. A single 15- to 20-week course has been shown to produce complete and prolonged clearing in many patients. If a second course is ever needed, it should not be started until at least two months after finishing the first, because acne may continue to improve even after stopping.
