Sceletium and Butorphanol

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

Moderate

CNS DEPRESSANTS

Why this applies to Butorphanol

Butorphanol falls under CNS DEPRESSANTS — the group Sceletium interacts with.

Theoretically, concomitant use of sceletium and CNS depressants might result in additive sedative effects.
Some evidence suggests that sceletium has sedative properties.
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

Butorphanol (Stadol) is a strong opioid pain reliever, and one of its most common effects is making you feel drowsy, foggy, or slowed down. Sceletium, or kanna, seems to have its own calming, mildly sedating effect based on lab research. Put the two together and those sleepy effects could stack up, so you might feel more groggy, dizzy, or unsteady than you'd expect.

I want to be honest about the evidence here: this concern is theoretical, based on how these substances are thought to work rather than on solid human studies. Still, since both can dull the central nervous system, it's worth a quick chat with your pharmacist or doctor before combining them. Please don't change anything on your own.

From our pharmacist’s overview on the Butorphanol page

“Slowed breathing and deep sedation are the risks that tower over any opioid, and most of this list threatens to push butorphanol (Stadol), an opioid pain reliever, in exactly that direction. Of the 100 supplement and herbal ingredients on file, 78 add their own sedative pull, so this page deserves genuine care, not a skim.”

About Sceletium

What is Sceletium?

  • Anxiety and stress
  • Low mood
  • Mental focus and cognition
  • Relaxation
  • Traditional use as a mood lifter

Sceletium (often sold as 'kanna') is a South African plant traditionally used to ease stress and lift mood. Early human studies are small and short, so its benefits are not well proven. Talk to your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.

About Butorphanol Injection

What Is Butorphanol Injection Used For?

Brand name: Stadol

Butorphanol Tartrate Injection is used to manage pain severe enough to require an opioid when other treatments are not adequate. It is also used as a preoperative or pre-anesthetic medication and as a supplement to balanced anesthesia during surgical procedures.

Butorphanol Tartrate Injection is also indicated for relief of pain during labor in patients at full term in early labor. Because of serious risks including addiction, misuse, and overdose, it is reserved for situations where alternative treatments are ineffective or not tolerated.
