HEPATOTOXIC DRUGS

Why this applies to Trazodone

Trazodone falls under HEPATOTOXIC DRUGS — the group Ligandrol interacts with.

Theoretically, concomitant use might have additive hepatotoxic effects.
In case reports, patients were diagnosed with liver injury thought to be related to the use of products containing ligandrol.
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 concern with pairing trazodone and Ligandrol: this isn't about Ligandrol changing how your body breaks down trazodone. Instead, it's about both being potentially hard on the liver. Trazodone, on its own, occasionally causes liver irritation in some people. Ligandrol (an unapproved SARM) has been tied to liver injury in several case reports. Stack them together and the worry is that the strain could add up.

To be honest, this is based on weak, anecdotal evidence, not solid studies, so I don't want to alarm you. Still, signs like yellowing skin or eyes, dark urine, unusual tiredness, or belly pain on the right side deserve quick attention. I'd genuinely steer clear of Ligandrol altogether, but please talk it over with your doctor or pharmacist before making any changes.

Ligandrol (LGD-4033) is a synthetic selective androgen receptor modulator (SARM), not a natural herb or approved dietary supplement. It is not approved for human use, is banned in sports, and has been linked to liver injury and hormonal disruption, so it should not be taken as a supplement.
