Sage and acetaminophen, dextromethorphan, doxylamine

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

Moderate

CNS DEPRESSANTS

Why this applies to acetaminophen, dextromethorphan, doxylamine

acetaminophen, dextromethorphan, doxylamine falls under CNS DEPRESSANTS — the group Sage interacts with.

Theoretically, taking sage might increase the sedative and adverse effects of CNS depressants.
Some constituents of sage have CNS depressant 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 simple version for NyQuil. One of its ingredients, doxylamine, is an antihistamine that already makes you drowsy, and dextromethorphan can add to that sleepy feeling. The concern on file is that certain compounds in sage may have a mild calming effect of their own, so in theory they could stack on top of NyQuil's drowsiness and leave you feeling extra groggy, dizzy, or slow to react.

I want to be honest with you: this is a theoretical concern based only on lab and animal studies, not real cases in people. A pinch of sage in your cooking is very unlikely to matter. Concentrated sage capsules or the essential oil are where I'd be more cautious. If you take those regularly, just run it by your pharmacist or doctor first.

About Sage

What is Sage?

Sage
  • Sore throat and mouth irritation
  • Digestive upset
  • Excessive sweating
  • Memory and thinking
  • Menopause symptoms (hot flashes)
  • General antioxidant support

Sage is a common kitchen herb that is generally safe in food amounts and is traditionally used for sore throats, digestion, sweating, and memory. Some early research is encouraging for sore throat and menopausal hot flashes, but most uses are not well proven. Concentrated extracts and the essential oil should be used carefully because high doses contain a compound called thujone, which can be harmful.
