Water Avens + Dabrafenib
Dabrafenib brand name: Tafinlar.
We found no known interaction between Water Avens and Dabrafenib 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 Dabrafenib states a food rule worth keeping to.
Water Avens and Dabrafenib
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 Dabrafenib 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 Dabrafenib, 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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Dabrafenib Products Have a Food Rule — Water Avens Should Not Break It
At least one FDA label for a product containing Dabrafenib says to take it on an empty stomach. Most supplements — Water Avens included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Dabrafenib on its own and move Water Avens to a meal later in the day.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Dabrafenib 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.
TAFINLAR Capsules Take TAFINLAR capsules on an empty stomach (at least 1 hour before or 2 hours after a meal) [see Clinical Pharmacology (12.3)] .
From the Dosage and Administration section of the FDA label we read for Dabrafenib — 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.

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 20, 2026. The Water Avens and Dabrafenib 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 Dabrafenib
What Is Dabrafenib Used For?
Brand name: Tafinlar
Dabrafenib is used to treat cancers that carry a specific change (mutation) in the BRAF gene — most often called a BRAF V600E or V600K mutation. These mutations cause cancer cells to grow out of control. Before starting this medicine, a tumor test must confirm the mutation is present.
It can be used alone or — more commonly — paired with another targeted drug, trametinib. Conditions it treats include advanced or inoperable melanoma (skin cancer), certain lung cancers, anaplastic thyroid cancer, low-grade brain tumors (glioma) in children, and other solid tumors with the same mutation that haven't responded to prior treatment.
