Delta-9-tetrahydrocannabinol (thc) 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 Delta-9-tetrahydrocannabinol (thc) interacts with.

Theoretically, CYP3A4 inducers might reduce the levels and clinical effects of THC.
THC is a substrate of CYP3A4 enzymes.
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 some good news if you're using Luzu (luliconazole) cream while also using THC. This interaction is listed because some CYP3A4 inducers can speed up how fast your body clears THC, which would lower THC's levels and weaken its effects. But luliconazole is a topical antifungal. You rub it on the skin to treat things like athlete's foot, jock itch, or ringworm, and very little of it gets into your bloodstream.

Because so little is absorbed, it's very unlikely to change how your liver handles THC in any meaningful way. On top of that, this concern is purely theoretical and based on pharmacology, not real-world reports. I wouldn't lose sleep over it, but if you have any questions, your pharmacist is always happy to talk it through with you.

About Delta-9-tetrahydrocannabinol (thc)

What is Delta-9-tetrahydrocannabinol (thc)?

Delta-9-tetrahydrocannabinol (thc)
  • Chronic or nerve pain
  • Nausea and vomiting from chemotherapy
  • Appetite loss and weight loss
  • Muscle spasticity
  • Sleep problems

THC is the main mind-altering compound in cannabis and is best known for causing a 'high.' A prescription form (dronabinol) is approved for chemotherapy-related nausea and appetite loss, but for most other uses the evidence is mixed or limited, and THC can impair thinking and driving. It should be avoided in pregnancy and breastfeeding and used only with medical guidance.
