Herb Robert + nitisinone
nitisinone brand names: Orfadin, Nityr.
We found no known interaction between Herb Robert and nitisinone 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.
Herb Robert and nitisinone
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 nitisinone and Herb Robert 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 Herb Robert at all — not against nitisinone, 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.

From our pharmacist’s overview on the nitisinone page
“For a child or adult with hereditary tyrosinemia type 1, nitisinone (Orfadin, Nityr) is the medication holding a dangerous metabolic disease in check, which is why the 21 supplements on this page warrant genuine care rather than a shrug. Activated charcoal is the single major-rated entry and the one to understand first, since it can so…”

About Herb Robert
What is Herb Robert?
- Digestive upset
- Wound and skin care
- Sore throat and mouth irritation
- Respiratory complaints
- General 'detox' tonic
Herb Robert is a traditional European herb used for digestion, wounds, and minor inflammation, but there is very little human research to confirm it works for any condition. It is likely fine in small amounts as a tea for most healthy adults, but its safety has not been well studied. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

An interaction check asks whether these two react with each other — it does not ask whether Herb Robert is a good idea for someone in your situation. Here is what our Herb Robert record says about it on its own.
Herb Robert: dosing
There is no established, standardized dose for Herb Robert. Traditional use involved brewing a small amount of the dried herb as a tea or applying crushed fresh leaves to the skin, but these amounts were not measured in a consistent, science-based way.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount.

About Nitisinone
What Is Nitisinone Used For?
Brand names: Orfadin, Nityr
Nitisinone (as Orfadin capsules, Orfadin oral suspension, Nityr tablets, and generic Nitisinone capsules) is used to treat hereditary tyrosinemia type 1 (HT-1) — a rare inherited disease in which the body cannot properly break down the amino acid tyrosine, leading to toxic buildup that damages the liver and kidneys. It is used in both adults and children, always together with a strict low-tyrosine, low-phenylalanine diet.
Harliku tablets are approved for a different rare inherited condition: alkaptonuria (AKU). In adults with AKU, Harliku reduces the level of homogentisic acid (HGA) — a harmful substance that builds up in the urine and body tissues. Harliku is not approved for HT-1, and the other nitisinone products are not approved for AKU.
Most-Reported Side Effects for nitisinone
