Uva Ursi and Triazolam

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Triazolam

Triazolam falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Uva Ursi interacts with.

Theoretically, uva ursi may decrease the metabolism of CYP3A4 substrates.
In vitro, uva ursi appears to inhibit CYP3A4. This effect has not been reported in humans.
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 basic idea with Triazolam (Halcion) and uva ursi. Your liver uses an enzyme called CYP3A4 to clear triazolam out of your system. In lab studies, uva ursi seems to slow that enzyme down. If that happened in a real person, triazolam could build up and hit harder than expected, meaning more next-day grogginess, dizziness, confusion, or feeling unsteady on your feet.

The honest part: this has only been seen in test-tube studies, never confirmed in people, so it's more of a theoretical concern than something we know happens. Still, since triazolam is a strong sleep medicine, I'd run it by your pharmacist or doctor before pairing the two, especially with concentrated uva ursi supplements rather than tiny amounts.

About Uva Ursi

What is Uva Ursi?

Uva Ursi
  • Urinary tract infections
  • Urinary discomfort
  • Mild diuretic
  • Kidney stones
  • Skin conditions

Uva ursi is a traditional herb used mainly for urinary tract infections, and its leaves contain a compound called arbutin that may have antimicrobial effects in the urine. Evidence in people is limited, and because high doses or long-term use may be harmful to the liver and could be toxic, it should only be used short-term and with guidance from a healthcare professional. Avoid it during pregnancy and breastfeeding.
