Interaction report

Black Mulberry and Meperidine, Promethazine

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 Meperidine, Promethazine and Black Mulberry 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.

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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Meperidine, Promethazine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Meperidine, Promethazine is filed under 11 classifications — including phenothiazines, narcotic drugs, serotonergic drugs. Black Mulberry has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and midazolam (versed) (moderate) — and none of Meperidine, Promethazine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Black Mulberry Itself Has Been Linked To

This is not an interaction — nothing below involves Meperidine, Promethazine. It is the side-effect record for Black Mulberry on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Black Mulberry, this list is the first place to look.

A skin rash Additional detail
“Topically, black mulberry leaf may cause contact dermatitis. A case of lichenoid contact dermatitis was reported in a 68-year-old male who came into contact with black mulberry leaves while picking black mulberries.”

Everything above comes from the Natural Medicines adverse-effect record for Black Mulberry — expand a row for the licensed statement it rests on. We haven’t matched Meperidine, Promethazine to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Meperidine, Promethazine.

From our pharmacist’s overview on the Meperidine, Promethazine page

“Meprozine combines meperidine, an opioid painkiller, with promethazine, a sedating antihistamine, so it already slows the brain on two fronts. I would read this list of 207 supplements and herbal ingredients with genuine care, starting with the 10 rated major.”

About Black Mulberry

What is Black Mulberry?

General antioxidant support
Blood sugar support
Cholesterol and heart health
Digestive health
Cold and sore throat remedies (traditional)

Black mulberry is a nutritious fruit rich in antioxidants and vitamins, and it is generally safe to enjoy as a food. Some early research on its leaf and fruit extracts hints at benefits for blood sugar and cholesterol, but the evidence is still limited. Talk with your pharmacist or doctor before using concentrated extracts, especially if you have a health condition.

Morus nigra · Moraceae · Fruit (berries), leaves, and sometimes root bark · Fresh or dried fruit, juice, jam, tea, powder, and capsules or extracts

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

Black Mulberry: dosing

There is no official standardized dose for black mulberry supplements. The amount in products varies widely depending on whether the fruit, leaf, or an extract is used.If you use a commercial product, follow the directions on the label and do not take more than recommended. Eating the fresh or dried fruit as part of a normal diet does not require special dosing.
