Dhea and Selinexor

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Selinexor

Selinexor falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Dhea interacts with.

Theoretically, DHEA might increase the levels of drugs metabolized by CYP3A4.
Some preliminary evidence shows that DHEA may inhibit CYP3A4; however, the clinical significance of this potential interaction is not known.
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. Your liver uses an enzyme called CYP3A4 to help clear Selinexor (Xpovio) out of your body. There's some early, fairly weak evidence that DHEA may slow that same enzyme down. If it does, Selinexor could clear a bit more slowly and build up, which in theory might make its side effects stronger, things like nausea, vomiting, poor appetite, fatigue, low sodium, and low blood counts.

I want to be honest that this is mostly theoretical and based on anecdotal data, so we really don't know how much it matters in real life. Still, Selinexor is a serious cancer medicine, so please don't start DHEA without first checking with your oncologist or pharmacist.

From our pharmacist’s overview on the Selinexor page

“Selinexor (Xpovio) treats multiple myeloma and certain lymphomas, and its side effects are rough enough at intended doses that any shift in its blood level deserves genuine caution. Almost all of the 138 supplements and herbs listed here, 121 of them, can change how a liver enzyme called CYP3A4 handles the drug, pushing its level up or…”

About Dhea

What is Dhea?

Dhea
  • Anti-aging and low DHEA levels
  • Mood and depression
  • Vaginal dryness and sexual health
  • Fertility support
  • Muscle mass and athletic performance
  • Adrenal insufficiency

DHEA is a natural hormone that the body makes and that declines with age, and it is sold as a supplement claiming many benefits. The evidence is mixed and limited for most uses, and because it acts as a hormone it can cause real side effects. Talk to a pharmacist or doctor before using it, especially if you have a hormone-sensitive condition.

About Selinexor

What Is Selinexor Used For?

Brand name: Xpovio

Xpovio (selinexor) is used to treat multiple myeloma in adults. When used together with bortezomib and dexamethasone, it is for adults who have had at least one prior treatment. This combination is sometimes called XVd.

Xpovio is also used with dexamethasone alone (called Xd) for adults with relapsed or refractory multiple myeloma — meaning the cancer came back or stopped responding — who have already tried at least four prior therapies and whose disease no longer responds to several other standard drug types.
