Sage and Levorphanol

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

Moderate

CNS DEPRESSANTS

Why this applies to Levorphanol

Levorphanol 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: Levorphanol is a strong opioid pain reliever, and like all opioids it can make you drowsy, slow your breathing, and cloud your thinking. Sage isn't a pain medicine, but some of its natural compounds appear to have a mild calming (sedative) effect of their own. The concern is that stacking the two could add up, leaving you more sleepy, foggy, or lightheaded than you'd expect from the Levorphanol alone.

I want to be honest about how solid this is: it's a theoretical concern based only on lab and animal studies, not real-world reports. Sprinkling sage on your food is very unlikely to matter. Concentrated sage extracts or the essential oil are where I'd be more cautious. If you take Levorphanol daily, just run any sage supplement past your pharmacist or doctor first.

From our pharmacist’s overview on the Levorphanol page

“Most of the ingredients that interact with levorphanol (Levo-Dromoran) pile onto the same hazard, deeper sedation. Because levorphanol is a potent opioid painkiller, that stacking can slow breathing rather than just cause drowsiness, so this page deserves real vigilance before you add a supplement to it.”

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.

About Levorphanol

What Is Levorphanol Used For?

Brand name: Levo-Dromoran

Levorphanol Tartrate Tablets are used to manage pain severe enough to require an opioid — specifically when non-opioid or other pain treatments haven't provided enough relief or aren't a good fit for the patient.

It is not meant for everyday or mild pain. Prescribers weigh the serious risks of opioid therapy carefully before choosing this medication, and it should be used for only as long as the pain requires it.
