No Known Interaction
The bottom line No known interaction

We found no known interaction between Diacylglycerol and Levorphanol in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Diacylglycerol and Levorphanol

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Levorphanol and Diacylglycerol in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Diacylglycerol at all — not against Levorphanol, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

  • Dependence or withdrawal symptoms Worth acting on
  • Serotonin syndrome Worth acting on
  • Thoughts of self-harm Worth acting on
  • Memory problems Worth acting on
  • Trouble passing urine Worth acting on
  • Low blood sugar Worth acting on
  • A slow heartbeat Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Levorphanol. Read the label on DailyMed › Diacylglycerol’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Diacylglycerol side to compare — that is a limit of the record, not a statement that Diacylglycerol has no side effects.

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.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Diacylglycerol is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Diacylglycerol reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Diacylglycerol and Levorphanol records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Diacylglycerol

What is Diacylglycerol?

  • Weight management
  • Reducing body fat
  • Lowering blood triglycerides
  • Healthy cooking oil substitute

Diacylglycerol (DAG) is a type of fat found naturally in small amounts in many edible oils and was once sold as a specialty cooking oil marketed for weight and fat management. Evidence for meaningful weight-loss benefits over regular cooking oils is weak and mixed, and one major DAG oil product was pulled from the market over a processing-related contaminant concern. Talk with your pharmacist or doctor before relying on it for any health purpose.

Edible oil component (derived from vegetable oils such as soybean and rapeseed) · Cooking oil, salad dressings, and processed food products

An interaction check asks whether these two react with each other — it does not ask whether Diacylglycerol is a good idea for someone in your situation. Here is what our Diacylglycerol record says about it on its own.

Diacylglycerol: dosing

There is no established or standardized dose of diacylglycerol for any health benefit. When sold as a cooking oil, it was simply used in place of regular oil in everyday cooking.If you come across a diacylglycerol product, follow the label directions and do not assume that using more will give you any extra benefit.

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.
