No Known Interaction

The bottom line No known interaction

We found no known interaction between Nicotinamide Riboside and Scopolamine 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Nicotinamide Riboside and Scopolamine

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 Scopolamine and Nicotinamide Riboside 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.

How we checked

Why No Interaction Is Listed for Scopolamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Scopolamine is filed under 4 classifications — including anticholinergic drugs, topical drugs, oral drugs. Nicotinamide Riboside has documented interactions with 1 drug class — the most serious being antihypertensive drugs (minor) — and none of Scopolamine’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

No Interaction Found — But Data Suggests Nicotinamide Riboside and Scopolamine May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

Reported for Nicotinamide Riboside but not commonly for Scopolamine: stomach upset, sweating, muscle pain and diarrhea.

Effects for Scopolamine come from the ADVERSE REACTIONS section of its FDA label; effects for Nicotinamide Riboside come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 6,682 voluntary FDA FAERS reports for Scopolamine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it.

See Every Supplement That Interacts With Scopolamine

This page covers Nicotinamide Riboside only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Scopolamine page lists 51 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), Henbane (major), Scopolia (major) and Angel's Trumpet (moderate).

By severity: 4 major · 34 moderate · 13 minor.

From our pharmacist’s overview on the Scopolamine page

“Scopolamine, the motion sickness medicine most people wear as the Transderm Scop patch, sits on the serious end of supplement interactions, so learn the four major entries first. Most of the 51 ingredients here, 30 of them, pile the same anticholinergic side effects on top of the drug: dry mouth, blurred vision, constipation, confusion.”

About Nicotinamide Riboside

What is Nicotinamide Riboside?

  • Healthy aging
  • Boosting cellular energy
  • Supporting metabolism
  • General wellness
  • Athletic recovery

Nicotinamide riboside (NR) is a form of vitamin B3 that the body converts into NAD+, a molecule involved in cellular energy and repair. Early human studies show it can reliably raise NAD+ levels and appears generally well tolerated, but solid evidence that it improves aging, energy, or specific health conditions is still limited. Talk with your pharmacist or doctor before starting it.

Not applicable (a form of vitamin B3) · Capsules, tablets, powders

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

Nicotinamide Riboside: dosing

There is no official, standardized dose of nicotinamide riboside for any health condition. Research studies have used a range of amounts, but these are not formal recommendations.The safest approach is to follow the dose printed on the product label and not exceed it without professional guidance. They can help you decide whether NR is appropriate for you and what amount makes sense.

Scopolamine Transdermal System (also sold as Transderm Scōp) is approved for adults to prevent nausea and vomiting caused by motion sickness. You apply it before travel to help stop queasiness before it starts.

Taking Nicotinamide Riboside and Scopolamine Together: Common Questions

Is it safe to take Nicotinamide Riboside with Scopolamine?
We do not list a known interaction between Nicotinamide Riboside and Scopolamine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Nicotinamide Riboside and Scopolamine have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Nicotinamide Riboside and Scopolamine combination checked?
Interactions in our licensed database are recorded against drug classes. Scopolamine is filed under 4 classifications, and Nicotinamide Riboside has documented interactions with 1 drug class — none of Scopolamine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Nicotinamide Riboside interact with any other medications?
Yes. Nicotinamide Riboside has 172 documented drug interactions in our database — Scopolamine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Scopolamine interact with any supplements?
Yes. Scopolamine has documented interactions with 51 supplements in our database — Nicotinamide Riboside is not one of them. The Scopolamine interaction page linked on this page lists every one, ranked by severity.
