Drug & supplement interaction

Riboflavin + Paliperidone Palmitate

Paliperidone Palmitate brand name: Invega Trinza.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Oct 4, 2026

The bottom line No known interaction

We found no known interaction between Riboflavin and Paliperidone Palmitate 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 Paliperidone Palmitate

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 Paliperidone Palmitate 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 Paliperidone Palmitate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Paliperidone Palmitate is filed under 3 classifications — antipsychotic drugs, qt interval-prolonging drugs, seizure threshold lowering drugs. Riboflavin has documented interactions with 1 drug class — the most serious being tetracycline antibiotics (moderate) — and none of Paliperidone Palmitate’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Riboflavin and Paliperidone Palmitate 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.

“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.”

Overlapping uses

What Paliperidone Palmitate Is Prescribed For, and What Riboflavin Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Paliperidone Palmitate is a prescription medicine with approved uses on its FDA label. Riboflavin is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Paliperidone Palmitate is prescribed for: Paliperidone injections are used for schizophrenia in adults. Invega Hafyera is an every-six-month injection. It is for adults who have already been adequately treated with a once-a-month paliperidone injection (such as Invega Sustenna) for at least four months, or an every-three-month injection (such as Invega Trinza) for at least one three-month cycle. Invega Sustenna dosing also covers schizoaffective disorder in adults.

Erzofri and Invega Trinza are also in this group, but the supplied evidence does not state their specific uses.

Riboflavin has been studied for:

Depression studied, not established Riboflavin has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Riboflavin for depression

It is unclear if oral riboflavin is beneficial for depression.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Paliperidone Palmitate on your own; if you are taking Riboflavin for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Paliperidone Palmitate page

“Paliperidone palmitate (Invega Trinza), a long-acting injection for schizophrenia, can lengthen the heart's QT interval on its own, so the supplements on this page deserve real care rather than casual curiosity. Nearly half of the interacting ingredients can stretch that interval further and raise the risk of a dangerous heart rhythm,…”

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.

From our Riboflavin monograph — the full record covers uses, side effects and every documented interaction.

Taking Riboflavin and Paliperidone Palmitate Together: Common Questions

Is it safe to take Riboflavin with Paliperidone Palmitate?

We do not list a known interaction between Riboflavin and Paliperidone Palmitate. 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 Paliperidone Palmitate 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.

Are Riboflavin and Paliperidone Palmitate used for the same thing?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Riboflavin in each. That is a conversation for your prescriber, especially if Paliperidone Palmitate is being adjusted to a target.

How was the Riboflavin and Paliperidone Palmitate combination checked?

Interactions in our licensed database are recorded against drug classes. Paliperidone Palmitate is filed under 3 classifications, and Riboflavin has documented interactions with 1 drug class — none of Paliperidone Palmitate'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 — Paliperidone Palmitate 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 Paliperidone Palmitate interact with any supplements?

Yes. Paliperidone Palmitate has documented interactions with 27 supplements in our database — Riboflavin is not one of them. The Paliperidone Palmitate interaction page linked on this page lists every one, ranked by severity.
