Drug & supplement interaction

Biofeedback + Allopurinol

Allopurinol brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Biofeedback and Allopurinol 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.

Biofeedback and Allopurinol

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 Allopurinol and Biofeedback in our sources. This does not guarantee that the combination is completely free of risk — research on Biofeedback alongside specific medications may be limited.

Biofeedback is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is appropriate for your health and treatment. 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.

Biofeedback safety at a glance

Biofeedback overall Generally safe Biofeedback is non-invasive and considered very safe for most people.
Pregnancy Generally safe Generally considered safe in pregnancy and sometimes used for stress, but check with your provider first.
Breastfeeding Generally safe There is no known risk while breastfeeding since nothing is ingested.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Allopurinol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Allopurinol is filed under 5 classifications — including antigout drugs, nephrotoxic drugs, hepatotoxic drugs. Biofeedback has documented interactions with 1 drug class — the most serious being seizure threshold lowering drugs (moderate) — and none of Allopurinol’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

Biofeedback Does Interact With Other Medications

What to actually watch for

No Interaction Found — But Data Suggests Biofeedback and Allopurinol 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 having Biofeedback while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Tiredness / Dizziness / Headache Additional detail

    Biofeedback

    “Biofeedback is generally well tolerated. Electroencephalogram (EEG) biofeedback has been linked to reports of headaches, tiredness, dizziness, and decreased or increased seizure threshold. The tape from biofeedback sensors can cause skin irritation in some people.”

Reported for Biofeedback but not commonly for Allopurinol: seizures.

Effects for Allopurinol come from the ADVERSE REACTIONS section of its FDA label; effects for Biofeedback come from the Natural Medicines adverse-effect record, quoted above.

Everything else you take

See Every Supplement That Interacts With Allopurinol

This page covers Biofeedback only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Allopurinol page lists 60 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Siberian Cocklebur (major) and Wine (major).

By severity: 5 major · 45 moderate · 10 minor.

From our pharmacist’s overview on the Allopurinol page

“Allopurinol (Zyloprim) prevents gout attacks by lowering uric acid, and I would give this list real weight, because 5 of the 60 supplements and herbs on file carry a major rating. The largest cluster, 38 ingredients, is products that can stress the liver on their own, and regular beer or wine sits in that major group, since alcohol on…”

About Biofeedback

What is Biofeedback?

  • Chronic pain
  • Headaches and migraines
  • Anxiety and stress
  • High blood pressure
  • Urinary incontinence
  • Tension and muscle relaxation

Biofeedback is a mind-body technique, not an herb or supplement. It uses sensors to show you real-time information about body functions like heart rate, muscle tension, or skin temperature so you can learn to control them. It is generally very safe and has reasonable evidence for headaches, certain pain conditions, and pelvic floor problems, but it works best alongside standard medical care.

Not applicable (mind-body therapy, not a plant or supplement) · In-office sessions with sensors and a monitor, wearable devices, and home apps

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

Biofeedback: dosing

There is no pill or standard dose for biofeedback because it is a learned skill, not a substance. Treatment is usually given as a series of sessions, often weekly, with practice in between.The number of sessions needed varies by person and condition. Many programs involve several visits before skills are well learned. Home devices and apps come with their own instructions.For best results, work with a qualified, trained biofeedback practitioner and follow their plan.

About Allopurinol

What Is Allopurinol Used For?

Brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric

Allopurinol tablets (including Zyloprim) are used in adults to treat the signs and symptoms of gout — including gout attacks, tophi (uric acid deposits), joint damage, and kidney problems caused by uric acid. Allopurinol tablets are also used in adults to reduce recurrent calcium oxalate kidney stones when uric acid in the urine is too high, even after lifestyle changes.

For adults and children with leukemia, lymphoma, or solid tumor cancers, allopurinol is used to control uric acid levels that rise during cancer treatment. The injectable forms — Allopurinol sodium for injection and Aloprim — are specifically for patients who cannot take medicine by mouth and are given intravenously (through a vein) in a hospital or clinical setting. Note: allopurinol tablets are not recommended for people who have high uric acid levels but no symptoms.

Most-Reported Side Effects for Allopurinol

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 8,726 reports
Fatigue 8,284 reports
Dyspnea 7,956 reports

Having Biofeedback While Taking Allopurinol: Common Questions

Is it safe to have Biofeedback while taking Allopurinol?
We do not list a known interaction between Biofeedback and Allopurinol. 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 Biofeedback and Allopurinol have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Biofeedback and Allopurinol combination checked?
Interactions in our licensed database are recorded against drug classes. Allopurinol is filed under 5 classifications, and Biofeedback has documented interactions with 1 drug class — none of Allopurinol'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 Biofeedback interact with any other medications?
Yes. Biofeedback has 418 documented drug interactions in our database — Allopurinol 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 Allopurinol interact with any supplements?
Yes. Allopurinol has documented interactions with 60 supplements in our database — Biofeedback is not one of them. The Allopurinol interaction page linked on this page lists every one, ranked by severity.
