Borage and Luliconazole

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INDUCERS

Why this applies to Luliconazole

Luliconazole falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS — the group Borage interacts with.

Theoretically, taking borage with drugs that induce CYP3A4 might increase levels of pyrrolizidine alkaloid (PA) toxic metabolites.
Although borage seed oil contains little to no PAs, some borage plant parts, such as the leaf, flower, and seed, can contain hepatotoxic PAs. Hepatotoxic PAs are substrates of CYP3A4, which converts these chemicals into toxic metabolites. Tell patients to avoid borage preparations that are not certified and labeled as hepatotoxic PA-free.
Severity Moderate Likelihood Possible Evidence D

Interaction 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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the good news: Luzu (luliconazole) is a cream you rub right on the skin to clear up athlete's foot, jock itch, or ringworm. Very little of it gets into your bloodstream, so the worry that brought this interaction up almost certainly doesn't apply to you in real life.

The concern on file is theoretical and comes only from lab data. The idea is that certain medicines can speed up a liver enzyme (CYP3A4) that turns the natural toxins (pyrrolizidine alkaloids, or PAs) in some borage plant parts into harmful byproducts. But a skin cream like Luzu isn't going to drive your liver enzymes that way. The smarter move with borage is simply choosing a product clearly labeled PA-free, and checking with your pharmacist before you start it.
