Bitter Yam and Acitretin

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 Acitretin and Bitter Yam 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.

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.

Bitter Yam safety at a glance

Bitter Yam overall Use caution Human safety data are limited, and improperly prepared bitter yam can be toxic.
Pregnancy Avoid Not enough safety information exists, so it is best avoided during pregnancy.
Breastfeeding Avoid There is no reliable safety data, so avoid use while breastfeeding.

How we checked

Why No Interaction Is Listed for Acitretin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Acitretin is filed under 5 classifications — including retinoids, cytochrome p450 3a4 (cyp3a4) inhibitors, photosensitizing drugs. Bitter Yam has documented interactions with 1 drug class — the most serious being digoxin (lanoxin) (moderate) — and none of Acitretin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Acitretin’s Own FDA Label Lists

This is not an interaction — none of it involves Bitter Yam. These are the most notable effects listed in the ADVERSE REACTIONS section of Acitretin’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. 8 of them are worth acting on rather than waiting out — marked below.

  • Thoughts of self-harm Worth acting on
  • Muscle weakness Worth acting on
  • A heart attack Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • An allergic reaction Worth acting on
  • Dry skin mentioned in 7.7% of FDA reports for Acitretin
  • Hair loss

Showing the 10 most notable of 16 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 Acitretin. Read the label on DailyMed › Where a percentage is shown, it is the share of 4,849 voluntary FDA FAERS reports for Acitretin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Bitter Yam’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Bitter Yam side to compare — that is a limit of the record, not a statement that Bitter Yam has no side effects.

From our pharmacist’s overview on the Acitretin page

“A course of Acitretin (Soriatane) for severe psoriasis runs for months, long enough for a multivitamin or detox product to slip in unexamined, and with this drug that carelessness carries real risk. Two of the 53 interacting ingredients are rated major.”

About Bitter Yam

What is Bitter Yam?

Bitter Yam
  • Blood sugar support
  • Digestive complaints
  • Traditional food source
  • Wound and skin care (folk use)

Bitter yam is a wild African yam used traditionally as both food and folk medicine, often for blood sugar and digestion. Scientific evidence in humans is very limited, and some bitter yam species can be toxic if not properly prepared. Talk to a pharmacist or doctor before using it as a supplement.

Dioscorea dumetorum · Dioscoreaceae · Tuber (root) · Cooked tuber, dried powder, traditional preparations

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

Bitter Yam: dosing

There is no established, standardized dose of bitter yam as a supplement. Traditional use varies widely and depends on how the tuber is prepared.If you choose to use a commercial product, follow the directions on the label and do not take more than recommended.

About Acitretin

What Is Acitretin Used For?

Brand name: Soriatane

Acitretin capsules are approved to treat severe psoriasis in adults. It is typically reserved for patients whose psoriasis has not responded to other treatments, or when other treatments are not appropriate options.

Because of serious risks — including the risk of severe birth defects — acitretin is not a first-line choice. In women who could become pregnant, it should only be used when the benefits clearly outweigh the risks and strict pregnancy-prevention measures are in place.

Most-Reported Side Effects for Acitretin

From FAERS, the FDA’s public side-effect reporting system (4,849 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Psoriasis 1,184 reports
Fatigue 483 reports
Nausea 441 reports
Pruritus 441 reports
Headache 372 reports
