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

The product you're asking about, Talwin Compound, pairs aspirin with pentazocine, an opioid pain reliever. Pentazocine works in your brain and can already make you feel drowsy, foggy, or lightheaded. Galphimia glauca appears to have its own calming, sedative effect, so the concern here is simple: stacking two things that slow down the nervous system could leave you more sedated than you'd expect.

This is a theoretical caution based on how the herb behaves, not on strong human studies, so it's nothing to panic about. Still, if you notice extra sleepiness, slowed thinking, or trouble staying alert, that's worth paying attention to. Before combining them, please check with your pharmacist or doctor so they can weigh it for your situation.

From our pharmacist’s overview on the Aspirin, Pentazocine page

“Talwin Compound pairs pentazocine, an opioid painkiller, with aspirin, and I read its supplement list with more concern than most. The great majority of entries do one of two things: raise the bleeding risk that aspirin already carries, or deepen the sedation pentazocine causes.”
