African Wild Potato and Ketamine

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

Moderate

CYTOCHROME P450 2B6 (CYP2B6) SUBSTRATES

Why this applies to Ketamine

Ketamine falls under CYTOCHROME P450 2B6 (CYP2B6) SUBSTRATES — the group African Wild Potato interacts with.

In vitro research shows that African wild potato extract inhibits cytochrome P450 2B6 (CYP2B6). However, this effect has yet to be reported in humans. Until more is known, use with caution. Theoretically, concomitant use of African wild potato with CYP2B6 substrates might increase the risk for adverse effects from these substrates. Some of these drugs include ketamine (Ketalar), phenobarbital, orphenadrine (Norflex), secobarbital (Seconal), and dexamethasone (Decadron).
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 gist: your body relies on a liver enzyme called CYP2B6 to break ketamine down. In lab dish studies, African Wild Potato appeared to slow that enzyme. If it did the same thing inside your body, ketamine could clear more slowly and build up, meaning stronger and longer effects, like deeper sedation, dizziness, confusion, vivid dreams or hallucinations, higher blood pressure, or nausea.

I want to be honest about the evidence, though. This has only been seen in test tube research, not in real people, so it's a theoretical concern, not a proven one. Since ketamine is usually given in a medical setting, your care team controls the dose closely. Still, tell your doctor or anesthesiologist about any supplements you take so they can plan safely.
