Teazle and Pyridostigmine Bromide

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

Moderate

CHOLINERGIC DRUGS

Why this applies to Pyridostigmine Bromide

Pyridostigmine Bromide falls under CHOLINERGIC DRUGS — the group Teazle interacts with.

In vitro research suggests that teazle extract can inhibit acetylcholinesterase activity. Theoretically, concurrent use of teazle with other cholinergic drugs might have additive effects and increase the risk of cholinergic side effects.
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 basic idea with these two together. Pyridostigmine works by blocking an enzyme called acetylcholinesterase, which lets your body build up more of the signal that helps your muscles fire. That's exactly what helps with myasthenia gravis weakness. In lab dish studies, teazle extract seems to block that same enzyme. So in theory, stacking them could push that effect a little too far and add up.

If that happened, you might notice more of pyridostigmine's usual cholinergic side effects: belly cramps, diarrhea, nausea, drooling or watery eyes, muscle twitching, or a slower heartbeat. I want to be straight with you though, this is only a theoretical concern from test-tube work, not from real patients. Still, don't add teazle on your own. Run it by your pharmacist or doctor first.

From our pharmacist’s overview on the Pyridostigmine Bromide page

“Activated charcoal is the single major-rated risk among the 39 supplements on file for pyridostigmine (Mestinon, Regonol), and it belongs at the top of your attention. Charcoal can soak up the medicine in the gut before it works, and for someone counting on pyridostigmine to keep muscles strong in myasthenia gravis, a blunted dose can…”

About Teazle

What is Teazle?

Teazle
  • Lyme disease (folk use)
  • Joint and muscle pain
  • Osteoarthritis and rheumatoid arthritis
  • Skin conditions such as psoriasis
  • Wound healing

Teazle (Dipsacus fullonum) is a spiky plant used in traditional and folk medicine, most notably as a tincture marketed for Lyme disease and for joint pain and skin problems. There is very little high-quality human research to support any of these uses, so its benefits remain unproven. Talk with a pharmacist or doctor before trying it, and never use it to replace standard treatment for serious infections like Lyme disease.

About Pyridostigmine

What Is Pyridostigmine Used For?

Brand names: Mestinon, Regonol

Pyridostigmine bromide is approved specifically for military use as a pretreatment before potential exposure to soman, a chemical nerve agent. It is taken ahead of time to help protect the body's nervous system from soman's lethal effects — but only when it is also followed by atropine and pralidoxime (2-PAM) treatment if poisoning occurs.

It does not work on its own. Pyridostigmine must always be paired with protective gear (mask, hood, overgarments) and with the nerve-agent antidotes atropine and pralidoxime if exposure happens. It is not a treatment for soman poisoning — it is a preparatory step taken before exposure.
