Cabbage and Bellafoline, Caffeine, Ergotamine Tartrate, Pentobarbital

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

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Bellafoline, Caffeine, Ergotamine Tartrate, Pentobarbital

Bellafoline, Caffeine, Ergotamine Tartrate, Pentobarbital falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Cabbage interacts with.

Theoretically, cabbage might decrease levels of drugs metabolized by CYP1A2.
Some animal research suggests that cabbage or its constituent indole-3-carbinol might increase drug metabolism and elimination by stimulating CYP1A2 activity.
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 gist with Cafergot PB: cabbage may gently speed up a liver enzyme called CYP1A2. The caffeine in this combination product is cleared partly by that enzyme, so in theory eating large amounts of cabbage (or taking concentrated cabbage or indole-3-carbinol supplements) could make the caffeine wear off a bit faster. In plain terms, you might notice slightly less of caffeine's usual kick, like alertness or jitteriness. The other ingredients (ergotamine for migraines, belladonna alkaloids, and the barbiturate) aren't really driven by this enzyme, so they're not the concern here.

Honestly, this is a weak, theory-based signal from lab and animal studies, and none of these drugs are prodrugs that need activating. Normal cabbage on your plate is very unlikely to matter. If you're using cabbage supplements heavily, just mention it to your pharmacist or doctor.

From our pharmacist’s overview on the Bellafoline, Caffeine, Ergotamine Tartrate, Pentobarbital page

“Cafergot PB combines ergotamine, caffeine, pentobarbital, and belladonna alkaloids to treat migraine, and the person taking it is often the same person reaching for kava to sleep or an herbal energy product afterward, which is exactly where the trouble sits. This list warrants genuine care.”

About Cabbage

What is Cabbage?

Cabbage
  • Breast engorgement during breastfeeding
  • Joint pain and swelling (topical)
  • Digestive and stomach upset
  • General nutrition and antioxidant support
  • Skin and minor inflammation (topical)

Cabbage is a nutritious, low-calorie vegetable that is safe to eat as food and is sometimes applied to the skin as a leaf wrap for breast engorgement or sore joints. Most medicinal claims are based on tradition or limited research, with the strongest (though still modest) evidence being for cooling cabbage leaves on engorged breasts. Talk to your pharmacist or doctor before using cabbage in large amounts or as a treatment.
