The bottom line No known interaction

We found no known interaction between Isatis and Isotretinoin 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.

Isatis 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 Isatis 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 Isatis 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.

Isatis safety at a glance

Isatis overall Use caution Generally used short-term in traditional medicine, but human safety data are limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid There is no reliable safety data, so avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Isotretinoin’s Own FDA Label Lists

This is not an interaction — none of it involves Isatis. 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. Isatis’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Isatis side to compare — that is a limit of the record, not a statement that Isatis has no side effects.

See Every Supplement That Interacts With Isotretinoin

This page covers Isatis 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. Isatis 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 Isatis reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Isatis and Isotretinoin records this page draws on were last updated June 22, 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 Isatis

What is Isatis?

  • Colds and flu-like illness
  • Sore throat
  • Fever
  • Immune support
  • Antiviral and antimicrobial support

Isatis is a plant long used in traditional Chinese medicine, mainly for sore throats, fevers, and colds. Modern evidence in people is very limited, so its benefits are not well proven. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Isatis tinctoria · Brassicaceae · Root (Ban Lan Gen) and leaf (Da Qing Ye) · Capsules, tablets, granules, powders, teas, and tinctures

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

Isatis: dosing

There is no well-established standard dose for Isatis. Traditional preparations and modern products vary widely in strength and form.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount. A pharmacist or qualified healthcare provider can help you decide whether it is appropriate for you and review your other medicines and health conditions first.

About Isotretinoin

What Is Isotretinoin Used For?

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

Isotretinoin is used to treat severe recalcitrant nodular acne — large, deep, inflamed breakouts (nodules 5 mm or bigger) that haven't cleared with conventional treatments like antibiotics. It is approved for non-pregnant patients 12 years of age and older. Brands include Absorica, Absorica LD, Accutane, Amnesteem, Claravis, and generic isotretinoin capsules.

Because of its serious potential side effects, isotretinoin is reserved for patients whose acne is truly severe and has not responded to other standard treatments. A typical course lasts 15 to 20 weeks, and many patients experience prolonged remission — sometimes permanent clearing — after a single course.

Most-Reported Side Effects for Isotretinoin

From FAERS, the FDA’s public side-effect reporting system (46,523 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Depression 5,609 reports
Inflammatory bowel disease 5,250 reports
Colitis ulcerative 3,800 reports
Dry skin 2,326 reports
Pregnancy 2,080 reports
