Lotus and Pentobarbitone

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

Moderate

PENTOBARBITAL (Nembutal)

Theoretically, taking lotus concomitantly with pentobarbital might increase sedation.
Animal research shows that lotus extract increases pentobarbitone-induced sleeping time. It is not known if this occurs in humans or if this effect occurs with other barbiturates or sedatives.
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 situation with lotus and pentobarbitone. Pentobarbitone is a barbiturate, a strong sedative that already slows the brain and body down. The concern is that lotus may add to that calming effect, so the two together could make you more drowsy, more relaxed, and slower to wake up than the medicine alone. With sedatives, deep sleepiness, foggy thinking, and slowed breathing are the things we watch for.

I want to be honest about how strong this evidence is: it's theoretical. It comes from animal studies where lotus extract lengthened sleeping time, and we don't know if the same happens in people. Eating lotus as food is unlikely to be an issue, but concentrated lotus supplements are different. Before combining them, please check with your pharmacist or doctor.

From our pharmacist’s overview on the Pentobarbitone page

“Pentobarbitone is a barbiturate, one of the older and heavier sedatives, and the gap between a dose that helps sleep and one that slows breathing too far is not a generous one. That is why I read this particular list with genuine concern.”

About Lotus

What is Lotus?

Lotus
  • Digestive upset and diarrhea
  • Anxiety and relaxation
  • Sleep support
  • Blood sugar and cholesterol support
  • Skin and general wellness

Lotus is an edible aquatic plant used in food and traditional medicine across Asia, with parts like the seeds, leaves, and flowers taken for digestion, calm, and overall wellness. Most health claims come from laboratory and animal research rather than strong human studies, so its benefits as a supplement are not well proven. Eating lotus as food is generally safe, but talk to your pharmacist or doctor before using concentrated supplements, especially if you are pregnant, breastfeeding, or taking other medicines.
