Peyote and Pemoline

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

Major

STIMULANT DRUGS

Why this applies to Pemoline

Pemoline falls under STIMULANT DRUGS — the group Peyote interacts with.

Concomitant use of peyote with stimulant drugs may increase the risk of adverse CNS effects. Some CNS stimulants include nicotine, cocaine, sympathomimetic amines, and amphetamines.
Severity Major 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

Here's the gist with pemoline (Cylert): it's a central nervous system stimulant, much like the medicines used for attention and alertness. Peyote's active ingredient, mescaline, is a powerful psychedelic that also revs up brain activity. Stacking two things that both stimulate the brain can pile on the same kinds of effects.

Together they could add up to a faster or pounding heartbeat, higher blood pressure, jitteriness, trouble sleeping, anxiety, and in worse cases agitation or seizures. I want to be honest about the evidence here, this concern is based on how the two work in theory rather than firm studies. Still, the potential downside is serious enough that I'd never recommend combining them. Please talk with your doctor or pharmacist before using these together.
