Polypodium Leucotomos and Budesonide

Here is the interaction we found between these two, with the evidence behind it.

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Budesonide

Budesonide falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Polypodium Leucotomos interacts with.

Theoretically, Polypodium leucotomos might increase levels of drugs metabolized by CYP3A4.
In vitro and animal research suggests that Polypodium leucotomos can decrease the metabolism of midazolam by a mechanism possibly related to the inhibition of CYP3A4. However, a small study in humans suggests that taking Polypodium leucotomos with midazolam does not affect the metabolism of midazolam.
Severity Minor Likelihood Unlikely Evidence B

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: your body relies on an enzyme called CYP3A4 to break down budesonide. In a test tube, Polypodium leucotomos looked like it might slow that enzyme down, which in theory could let budesonide build up a bit higher than usual. Budesonide isn't a prodrug, so more drug hanging around would mean stronger steroid effects and a slightly greater chance of side effects like fluid retention, raised blood sugar, mood changes, or sleep trouble.

That said, I wouldn't lose sleep over this one. The real concern is mostly theoretical, and a small human study with a similar drug (midazolam) showed no actual effect. If you take budesonide regularly, just give your pharmacist or doctor a heads-up before adding this fern extract.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.

From our pharmacist’s overview on the Budesonide page

“Budesonide (Entocort EC, Pulmicort, Uceris) is a steroid designed to act locally in the gut or airways while the liver enzyme CYP3A4 clears most of what reaches the bloodstream. That design is exactly why this page warrants real care.”

About Polypodium Leucotomos

What is Polypodium Leucotomos?

  • Sun sensitivity and sunburn protection
  • Skin conditions like vitiligo and melasma
  • Polymorphic light eruption
  • Skin aging and photoaging
  • Atopic dermatitis support

Polypodium leucotomos is a fern extract taken by mouth, mostly studied as an add-on to (not a replacement for) sunscreen and for certain light-triggered skin conditions. Some early research is promising for reducing sun sensitivity, but the evidence is still limited and it should not replace standard sun protection. Talk with your pharmacist or doctor before starting it.

About Budesonide

What Is Budesonide Used For?

Brand names: Entocort EC, Pulmicort, Uceris, Tarpeyo, Eohilia

Budesonide inhalation suspension is used as a maintenance (long-term control) treatment for asthma in children 12 months to 8 years old. It also works as a preventive (prophylactic) therapy to reduce the frequency of asthma symptoms.

Important: This medication is not a rescue inhaler. It will not stop a sudden asthma attack. A separate fast-acting bronchodilator is needed for sudden symptoms.
