Ginger and Testosterone Undecanoate

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 Undecanoate

Testosterone Undecanoate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Ginger interacts with.

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction 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 honest picture on ginger and your testosterone undecanoate. The body processes oral testosterone partly through a liver enzyme called CYP3A4, and ginger has shown mixed signals in the lab. Some test-tube studies hint it might block that enzyme (which could let testosterone build up a bit), while others suggest it might speed the enzyme up (which could lower your levels). In plain terms, we honestly don't know which way it would go in a real person.

The good news is this is based on lab and animal data, not solid human reports, so I wouldn't lose sleep over it. Everyday ginger in food or tea is very unlikely to matter. If you want to use concentrated ginger supplements regularly, just give your pharmacist or doctor a heads-up first.

About Testosterone Injection

What Is Testosterone Injection Used For?

Brand names: Andriol, Aveed, Jatenzo, Kyzatrex

Testosterone injections replace testosterone when the body makes too little or none. The label describes this in men with primary hypogonadism (a problem in the testicles) and hypogonadotropic hypogonadism (a problem with the pituitary or hypothalamus signals).

Testosterone Enanthate Injection is also used to stimulate puberty in carefully selected boys with clearly delayed puberty. It may be used secondarily in some postmenopausal women with advanced, inoperable breast cancer that has spread to the bone, under an oncologist’s direction. Aveed is for hypogonadism in men and is not for use in women.
