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

This product pairs belladonna with phenobarbital, and that phenobarbital piece is the one I'd really watch with wine. Phenobarbital is a barbiturate, a strong central nervous system depressant. Alcohol works on the brain in a similar way, so putting the two together can stack their calming effects on top of each other and slow you down more than expected.

In real life that can mean heavy drowsiness, dizziness, slurred speech, poor balance, and trouble thinking clearly. In serious cases it can slow your breathing, which is the part that makes this a major concern. The belladonna side adds dry mouth and blurred vision too. Please don't change anything on your own, but do talk with your pharmacist or doctor about drinking while on Belap.

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.
