Interaction report

Cannabidiol (cbd) and Testosterone Enanthate

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Testosterone Enanthate

Testosterone Enanthate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Cannabidiol (cbd) interacts with.

Cannabidiol may increase levels of drugs that are metabolized by CYP3A4.
In vitro and animal research shows that cannabidiol inhibits CYP3A4. In human studies and case reports, cannabidiol has been associated with an increase in plasma levels of the CYP3A4 substrates zonisamide, tacrolimus, everolimus, citalopram, midazolam, and methadone.
Severity Moderate Likelihood Probable Evidence A

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for you. CBD can gently slow down an enzyme called CYP3A4, which is one of the pathways your liver uses to break down testosterone. In theory, that could let testosterone levels run a little higher than expected, which might mean more of its usual effects, like acne, oily skin, mood changes, fluid retention, or a bump in red blood cell counts on your lab work.

That said, testosterone is mainly cleared in several ways, so this particular interaction is on the milder, more theoretical side for an injectable like Xyosted. Since your doctor already tracks your testosterone and blood counts with regular labs, it's worth telling them you're using CBD so they can keep an eye on your numbers. Don't change anything on your own first.

From our pharmacist’s overview on the Testosterone Enanthate page

“Beer and wine both carry major ratings on this list, because heavy alcohol use can compound the strain testosterone enanthate (Xyosted) already places on the liver. That liver theme runs through 38 of the 184 ingredients on file, Siberian cocklebur among them, and with six interactions rated major overall, this page deserves genuine ca…”

About Cannabidiol (cbd)

What is Cannabidiol (cbd)?

  • Anxiety and stress
  • Sleep problems
  • Chronic pain
  • Certain seizure disorders
  • Inflammation

CBD is a compound from the cannabis (hemp) plant that does not cause a 'high.' It has strong evidence only for certain rare seizure disorders (as a prescription drug), while most other popular uses are still backed by limited or early research. Product quality varies a lot, so talk with your pharmacist or doctor before using it, especially if you take other medicines.

About Testosterone Injection

What Is Testosterone Injection Used For?

Brand name: Xyosted

Testosterone injection is primarily used in men whose bodies do not produce enough testosterone on their own — a condition called hypogonadism. This includes primary hypogonadism (a problem with the testicles themselves, such as from injury, infection, or surgery) and hypogonadotropic hypogonadism (caused by problems in the brain's hormone signaling from the hypothalamus or pituitary gland). It is also used to stimulate puberty in carefully selected adolescent males with clearly delayed puberty who have not responded to other support.

Testosterone Enanthate Injection is also approved for use in women with advanced, inoperable metastatic breast cancer (specifically skeletal metastases) who are one to five years past menopause, or in premenopausal women with hormone-responsive breast cancer who have had their ovaries removed. This use should be directed by an oncologist. Aveed (testosterone undecanoate) is specifically approved for male hypogonadism only.
