Drug & supplement interaction

Riboflavin + Aripiprazole Lauroxil

Aripiprazole Lauroxil brand names: Aristada, Aristada Initio Kit.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Riboflavin and Aripiprazole Lauroxil 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.

Interaction report

Riboflavin and Aripiprazole Lauroxil

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 Aripiprazole Lauroxil and Riboflavin 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 Aripiprazole Lauroxil

Interactions in our licensed database are recorded against drug classes, not just single drug names. Aripiprazole Lauroxil is filed under 10 classifications — including alpha-adrenergic antagonists, antipsychotic drugs, qt interval-prolonging drugs. Riboflavin has documented interactions with 1 drug class — the most serious being tetracycline antibiotics (moderate) — and none of Aripiprazole Lauroxil’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 Riboflavin and Aripiprazole Lauroxil May Share a Side Effect

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.

  • Diarrhea Additional detail

    “Orally, riboflavin has been associated with rare diarrhea and dose-related nausea. In one clinical study, one subject out of 28 reported having diarrhea two weeks after starting riboflavin 400 mg daily.”

    Aripiprazole Lauroxil

    Listed in the ADVERSE REACTIONS section of the FDA label for Aripiprazole Lauroxil. Read the label on DailyMed ›

Reported for Riboflavin but not commonly for Aripiprazole Lauroxil: passing urine more often and nausea.

Effects for Aripiprazole Lauroxil come from the ADVERSE REACTIONS section of its FDA label; effects for Riboflavin come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 4,532 voluntary FDA FAERS reports for Aripiprazole Lauroxil that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Aripiprazole Lauroxil

This page covers Riboflavin only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Aripiprazole Lauroxil page lists 233 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), American Hellebore (major), Arsenic (major), Beer (major) and Cesium (major).

By severity: 16 major · 187 moderate · 30 minor.

From our pharmacist’s overview on the Aripiprazole Lauroxil page

“Aripiprazole lauroxil (Aristada) is a long-acting antipsychotic injection, and because each dose keeps working for weeks, a bad supplement pairing cannot be undone by skipping a pill. So the 16 major-rated entries among its 233 interactions on file deserve to be understood first.”

About Riboflavin

What is Riboflavin?

  • Riboflavin deficiency
  • Migraine prevention
  • General energy and metabolism support
  • Healthy skin and eyes

Riboflavin (vitamin B2) is an essential nutrient your body needs to turn food into energy and to keep skin, eyes, and nerves healthy. It is generally very safe at typical doses, and the strongest evidence supports its use for treating deficiency, with some supportive (but not definitive) evidence for preventing migraines.

Vitamin (water-soluble B vitamin) · Tablets, capsules, softgels, multivitamins, B-complex products, fortified foods

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

Riboflavin: dosing

There is a recommended daily intake for riboflavin as a nutrient, and most people meet it through a normal diet. Do not assume that more is better.

Taking Riboflavin and Aripiprazole Lauroxil Together: Common Questions

Is it safe to take Riboflavin with Aripiprazole Lauroxil?
We do not list a known interaction between Riboflavin and Aripiprazole Lauroxil. 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 Riboflavin and Aripiprazole Lauroxil have any of the same side effects?
Yes — our sources link each of them separately to one 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 Riboflavin and Aripiprazole Lauroxil combination checked?
Interactions in our licensed database are recorded against drug classes. Aripiprazole Lauroxil is filed under 10 classifications, and Riboflavin has documented interactions with 1 drug class — none of Aripiprazole Lauroxil'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 Riboflavin interact with any other medications?
Yes. Riboflavin has 20 documented drug interactions in our database — Aripiprazole Lauroxil 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 Aripiprazole Lauroxil interact with any supplements?
Yes. Aripiprazole Lauroxil has documented interactions with 233 supplements in our database — Riboflavin is not one of them. The Aripiprazole Lauroxil interaction page linked on this page lists every one, ranked by severity.
