Yerba Mansa and Acetaminophen, Hydrocodone

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

Moderate

CNS DEPRESSANTS

Why this applies to Acetaminophen, Hydrocodone

Acetaminophen, Hydrocodone falls under CNS DEPRESSANTS — the group Yerba Mansa interacts with.

Theoretically, concomitant use might cause additive or prolonged sedative effects.
Severity Moderate Likelihood Probable Evidence D

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

Vicodin and Norco combine acetaminophen with hydrocodone, an opioid that can make you feel drowsy, foggy, or lightheaded and can slow your breathing at higher doses. The concern here is simple: if yerba mansa has any mild calming or sedating quality of its own, pairing it with hydrocodone could, in theory, pile on top of that drowsiness.

I'll be honest, this is a theoretical caution based on how these things work, not solid human studies, so I don't want you to panic. Still, since hydrocodone already affects alertness and breathing, it's worth being cautious. Watch for extra sleepiness or feeling off, avoid driving until you know how you react, and check with your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Acetaminophen, Hydrocodone page

“Someone taking hydrocodone with acetaminophen (Vicodin, Norco) for post-surgical or dental pain often reaches for a sleep aid, kava, or a glass of wine at night, and that is exactly where the risk sits. This combination calls for genuine vigilance.”

Yerba mansa is a traditional Southwestern and Mexican medicinal plant used for sore throats, skin problems, and infections.
