Delta-9-tetrahydrocannabinol (thc) and Gestodene

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS

Why this applies to Gestodene

Gestodene falls under CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS — the group Delta-9-tetrahydrocannabinol (thc) interacts with.

Theoretically, CYP3A4 inhibitors might increase 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Gestodene, the progestin in your birth control pill Minesse, can act as a mild blocker of an enzyme called CYP3A4. That same enzyme helps your body break down THC. So in theory, taking THC while you're on gestodene could slow how fast THC is cleared, letting a little more of it build up. In plain terms, that might make THC's effects feel a bit stronger or last longer, things like feeling more high, sleepy, dizzy, slowed thinking, or impaired driving.

Keep in mind this is theoretical, based on how these compounds work on paper, not on solid human studies. Gestodene is a fairly weak inhibitor, so any real effect is likely small. Still, if you notice THC hitting harder than usual, mention it to your pharmacist or doctor.

Delta-9-tetrahydrocannabinol (thc)
  • Chronic or nerve pain

It should be avoided in pregnancy and breastfeeding and used only with medical guidance.
