Wine and Belladonna, Ergotamine, Phenobarbital

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

Major

CNS DEPRESSANTS

Why this applies to Belladonna, Ergotamine, Phenobarbital

Belladonna, Ergotamine, Phenobarbital falls under CNS DEPRESSANTS — the group Wine interacts with.

Concomitant use may increase sedative and other adverse effects.
Concomitant use of alcohol with CNS depressants can increase sedative and other adverse effects, potentially through inhibition of the metabolism of certain CNS depressants.
Severity Major Likelihood Likely Evidence C

Well-controlled human studies have demonstrated the likely existence of this interaction.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Bellergal-S is a combination tablet, and one of its ingredients is phenobarbital, a barbiturate that calms the nervous system. When you add wine, which also slows down the brain, the two stack on top of each other. Alcohol can also slow how your body clears phenobarbital, so the sedative effect can build up.

Together they can leave you feeling very drowsy, foggy, dizzy, or unsteady on your feet, and in heavier amounts they can slow your breathing, which is the part that worries me most. The belladonna piece can add dry mouth and blurred vision too. This is considered a serious, likely combination, so please don't mix them without checking with your doctor or pharmacist first.

From our pharmacist’s overview on the Belladonna, Ergotamine, Phenobarbital page

“Bellergal-S packs three drugs into one tablet, and its supplement list earns real respect before you mix in anything else. Phenobarbital is a sedating barbiturate, belladonna adds drying anticholinergic effects, and ergotamine constricts blood vessels, so this combination collects interactions from several directions at once.”

About Wine

What is Wine?

  • Social and relaxation use
  • Heart health (popular belief)
  • Antioxidant intake
  • Aiding digestion (traditional use)
  • Culinary flavoring

Wine is an alcoholic beverage made from fermented grapes and is not a true dietary supplement or medicine. Despite popular claims about heart benefits, the alcohol it contains carries real health risks, and no amount of drinking can be recommended to improve health. If you drink, do so in moderation, and avoid alcohol entirely during pregnancy or if you have certain medical conditions.
