Drug & supplement interaction

Vitamin B6 + Deferiprone

Deferiprone brand name: Ferriprox.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Vitamin B6 and Deferiprone 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 label for Deferiprone states a food rule worth keeping to, and 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.

Vitamin B6 and Deferiprone

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 Deferiprone and Vitamin B6 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 Deferiprone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Deferiprone is filed under a single classification — oral drugs. Vitamin B6 has documented interactions with 5 drug classes — the most serious being amiodarone (cordarone) (moderate), antihypertensive drugs (moderate) and phenobarbital (luminal) (moderate) — and none of Deferiprone’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 Vitamin B6 and Deferiprone 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.

    Vitamin B6

    “Orally or by injection, vitamin B6 (pyridoxine) can cause nausea, vomiting, heartburn, abdominal pain, mild diarrhea, and loss of appetite. In a clinical trial, one patient experienced infectious gastroenteritis that was deemed possibly related to taking vitamin B6 (pyridoxine) orally up to 20 mg/kg daily.”

Reported for Vitamin B6 but not commonly for Deferiprone: an allergic reaction, sun sensitivity, numbness or tingling and drowsiness.

Effects for Deferiprone come from the ADVERSE REACTIONS section of its FDA label; effects for Vitamin B6 come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 3,004 voluntary FDA FAERS reports for Deferiprone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it.

Special populations

Vitamin B6 in Pregnancy & Breastfeeding

Pregnancy Likely Safe

When used orally and appropriately. A special sustained-release product providing vitamin B6 (pyridoxine) 75 mg daily is FDA-approved for use in pregnancy. Vitamin B6 (pyridoxine) is also considered a first-line treatment for nausea and vomiting in pregnancy by the American College of Obstetrics and Gynecology. However, it should not be used long-term or without medical supervision and close monitoring. The tolerable upper intake level (UL) refers to vitamin B6 in the form of pyridoxine and is 80 mg daily for those aged 14-18 years and 100 mg daily for 19 years and older.

Pregnancy Possibly Unsafe

When used orally in excessive doses. There is some concern that high-dose maternal vitamin B6 (pyridoxine) can cause neonatal seizures.

Lactation Likely Safe

When used orally in doses not exceeding the tolerable upper intake level (UL) of vitamin B6 in the form of pyridoxine 80 mg daily for those aged 14-18 years and 100 mg daily for those 19 years and older. The recommended dietary allowance (RDA) in lactating women is 2 mg daily. There is insufficient reliable information available about the safety of vitamin B6 when used in higher doses in breast-feeding women.

How to take them

Some Deferiprone Products Have a Food Rule — Vitamin B6 Should Not Break It

At least one FDA label for a product containing Deferiprone says to take it with food. If you take Vitamin B6 on an empty stomach out of habit, keep them separate — and take Deferiprone with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Deferiprone products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Overlapping uses

What Deferiprone Is Prescribed For, and What Vitamin B6 Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Deferiprone is a prescription medicine with approved uses on its FDA label. Vitamin B6 is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Deferiprone is prescribed for: Deferiprone is used to remove excess iron that builds up in the body from repeated blood transfusions — a condition called transfusional iron overload. Too much iron in the body can damage organs over time, so deferiprone works to capture and remove it. Ferriprox oral solution is approved for adults and children 3 years and older with thalassemia syndromes, sickle cell disease, or other anemias. Ferriprox tablets are approved for adults and children 8 years and older with the same conditions.

Read the rest of what Deferiprone is prescribed for

Deferiprone tablets (generic) are approved for adult patients with thalassemia syndromes when their current iron-removal treatment is not working well enough.

Vitamin B6 has been studied for:

  • Sickle cell disease studied, not established Vitamin B6 has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Vitamin B6 for sickle cell disease

    Oral vitamin B6 has only been evaluated in combination with other B vitamins; its effect when used alone is unclear.

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 Deferiprone on your own; if you are taking Vitamin B6 for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Deferiprone

This page covers Vitamin B6 only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Deferiprone page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Deferiprone page

“Deferiprone (Ferriprox) pulls excess iron out of the body in conditions like thalassemia, and that job depends on the pill actually being absorbed. Every one of the 17 supplements flagged against it threatens that step, which is why this list warrants real vigilance rather than a shrug.”

About Vitamin B6

What is Vitamin B6?

  • Morning sickness in pregnancy
  • Premenstrual syndrome (PMS)
  • Preventing or treating B6 deficiency
  • Nerve health and metabolism support
  • Nausea

Vitamin B6 (pyridoxine) is an essential water-soluble vitamin that your body needs for metabolism, brain function, and making red blood cells. It is best known for helping with pregnancy-related nausea and may help some people with PMS, but taking very high doses for long periods can cause nerve damage. Get most of your B6 from food, and check with a pharmacist or doctor before taking high-dose supplements.

Tablets, capsules, softgels, liquid drops, part of B-complex and multivitamins

An interaction check asks whether these two react with each other — it does not ask whether Vitamin B6 is a good idea for someone in your situation. Here is what our Vitamin B6 record says about it on its own.

Vitamin B6: dosing

There is no single "best" supplement dose for everyone, and the right amount depends on your age, health, and the reason you are taking it. Health authorities set recommended daily intakes and an upper limit to help avoid nerve-related side effects from too much.The safest approach is to follow the directions on the product label and not exceed the upper limit unless a healthcare provider tells you to. Avoid taking high-dose B6 for long periods on your own.If you take a B-complex or multivitamin, check how much B6 it already contains so you do not accidentally take too much from multiple products.

Pharmacist Counseling Corner

Taking Vitamin B6 and Deferiprone Together: Common Questions

Is it safe to take Vitamin B6 with Deferiprone?
We do not list a known interaction between Vitamin B6 and Deferiprone. 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 Vitamin B6 and Deferiprone have any of the same side effects?
Yes — our sources link each of them separately to 6 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.
Should I take Vitamin B6 and Deferiprone at the same time of day?
At least one FDA label for a product containing Deferiprone says to take it with food. If you take Vitamin B6 on an empty stomach out of habit, keep them separate and take Deferiprone with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Deferiprone products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Vitamin B6 and Deferiprone 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 Vitamin B6 in each. That is a conversation for your prescriber, especially if Deferiprone is being adjusted to a target.
How was the Vitamin B6 and Deferiprone combination checked?
Interactions in our licensed database are recorded against drug classes. Deferiprone is filed under 1 classification, and Vitamin B6 has documented interactions with 5 drug classes — none of Deferiprone'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 Vitamin B6 interact with any other medications?
Yes. Vitamin B6 has 210 documented drug interactions in our database — Deferiprone 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 Deferiprone interact with any supplements?
Yes. Deferiprone has documented interactions with 17 supplements in our database — Vitamin B6 is not one of them. The Deferiprone interaction page linked on this page lists every one, ranked by severity.
