Black Cohosh and Methyltestosterone Buccal

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to Methyltestosterone Buccal

Methyltestosterone Buccal falls under HEPATOTOXIC DRUGS — the group Black Cohosh interacts with.

Theoretically, taking black cohosh with hepatotoxic drugs may increase the risk of liver damage.
There is concern that black cohosh might be linked to cases of liver failure and autoimmune hepatitis.
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 thing to keep in mind with this pairing. Methyltestosterone is one of the oral anabolic steroids that's well known to be tough on the liver. With regular use it can raise liver enzymes and, in rare cases, cause more serious liver problems. Black cohosh has its own rare reports of liver injury. So the worry isn't a chemical reaction between the two, it's that both can lean on your liver at the same time, and that combined load could add up.

This concern is theoretical and based mostly on anecdotal reports, so it's a caution, not an alarm. Still, watch for yellowing of the skin or eyes, dark urine, belly pain, or unusual tiredness, and check in with your pharmacist or doctor before combining them so they can keep an eye on your liver.

About Black Cohosh

What is Black Cohosh?

Black Cohosh
  • Hot flashes and night sweats
  • Other menopause symptoms
  • Mood changes during menopause
  • Premenstrual syndrome (PMS)
  • Menstrual cramps

Black cohosh is a North American plant most often used to ease menopause symptoms like hot flashes, but the research is mixed and far from settled. It is generally well tolerated for short-term use, though rare reports of liver problems mean you should talk with your pharmacist or doctor before trying it, especially if you have liver disease.
