Drug & supplement interaction

Riboflavin + Sertraline

Sertraline brand name: Zoloft.

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 Sertraline 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 Sertraline

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 Sertraline 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 Sertraline

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sertraline is filed under 13 classifications — including antidepressant drugs, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Riboflavin has documented interactions with 1 drug class — the most serious being tetracycline antibiotics (moderate) — and none of Sertraline’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 Sertraline 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.

  • Diarrhea reported in 4.7% of FDA reports for Sertraline Additional detail

    Riboflavin

    “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.”

Reported for Riboflavin but not commonly for Sertraline: passing urine more often.

Effects for Sertraline 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 214,799 voluntary FDA FAERS reports for Sertraline 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.

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.

About Sertraline

What Is Sertraline Used For?

Brand name: Zoloft

Sertraline treats a range of mental health conditions. All formulations are approved for major depressive disorder (MDD) in adults and obsessive-compulsive disorder (OCD). The oral solution (including Zoloft oral solution) and several tablet formulations are also approved for panic disorder, post-traumatic stress disorder (PTSD), social anxiety disorder, and premenstrual dysphoric disorder (PMDD).

For OCD specifically, the capsule formulations and some tablet products are approved for use in adults and children aged 6 and older. Sertraline hydrochloride tablets (plain, not film-coated) are approved for OCD in pediatric patients as well. However, sertraline is not approved for major depressive disorder in children — only in adults.

Most-Reported Side Effects for Sertraline

From FAERS, the FDA’s public side-effect reporting system (218,320 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 13,865 reports
Fatigue 12,822 reports
Headache 11,106 reports

Taking Riboflavin and Sertraline Together: Common Questions

Is it safe to take Riboflavin with Sertraline?
We do not list a known interaction between Riboflavin and Sertraline. 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 Sertraline 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 Riboflavin and Sertraline combination checked?
Interactions in our licensed database are recorded against drug classes. Sertraline is filed under 13 classifications, and Riboflavin has documented interactions with 1 drug class — none of Sertraline'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 — Sertraline 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 Sertraline interact with any supplements?
Yes. Sertraline has documented interactions with 188 supplements in our database — Riboflavin is not one of them. The Sertraline interaction page linked on this page lists every one, ranked by severity.
