False Unicorn and Bedaquiline

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Bedaquiline

Bedaquiline falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group False Unicorn interacts with.

In vitro, false unicorn extract inhibits cytochrome P450 3A4 (CYP3A4) activity. Theoretically, false unicorn might increase the levels of CYP3A4 substrates. Drugs that might be affected include some calcium channel blockers (diltiazem, nicardipine, verapamil), chemotherapeutic agents (etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), glucocorticoids, cisapride (Propulsid), alfentanil (Alfenta), fentanyl (Sublimaze), losartan (Cozaar), fluoxetine (Prozac), midazolam (Versed), omeprazole (Prilosec), ondansetron (Zofran), propranolol (Inderal), fexofenadine (Allegra), and numerous others.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Bedaquiline (Sirturo). Your body clears this TB medicine using a liver enzyme called CYP3A4. In a test tube, False Unicorn appears to slow that same enzyme down. If that holds true in people, your body might clear bedaquiline a little more slowly, letting levels creep up. With this drug that mostly matters for the heart, since bedaquiline can affect your heart rhythm (a change called QT prolongation), and higher levels could make that more likely.

I'll be honest with you though: this is only lab-based evidence, not proven in real patients, so it's theoretical for now. Still, TB treatment is too important to gamble with. Please run False Unicorn past your pharmacist or TB doctor before adding it, and don't change anything on your own.

About False Unicorn

What is False Unicorn?

False Unicorn
  • Menstrual cramps

  • Female infertility support
  • Irregular periods
  • Digestive complaints

False Unicorn is a North American plant whose root has long been used in traditional medicine for women's reproductive and menstrual concerns. There is very little reliable human research to show it actually works, and safety has not been well studied, so it should be used with caution and never during pregnancy. Talk to your pharmacist or doctor before trying it.

About Bedaquiline

What Is Bedaquiline Used For?

Brand name: Sirturo

Sirturo (bedaquiline) is used as part of a combination treatment for pulmonary TB — TB that affects the lungs — caused by bacteria resistant to at least both rifampin and isoniazid. It is approved for adults and for children 2 years and older who weigh at least 8 kg (about 17.6 lbs).

Sirturo is not used for latent TB (TB infection with no active symptoms), TB outside the lungs, drug-sensitive TB, or infections caused by non-tuberculosis mycobacteria. It must always be used alongside other TB medicines — never alone.
