Drug & supplement interaction

Magnet Therapy + Phenylephrine

Phenylephrine brand names: Gilchew, AH Chew D, Gilchew IR, Sudafed PE, Biorphen.

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 Magnet Therapy and Phenylephrine 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

Magnet Therapy and Phenylephrine

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

Worth understanding: our licensed dataset holds no drug-interaction record for Magnet Therapy at all — not against Phenylephrine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Magnet Therapy 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.

Magnet Therapy safety at a glance

Magnet Therapy overall Use caution Static magnets are low-risk for most people but may be unsafe for those with implanted electronic devices.

Pregnancy Use caution Safety during pregnancy has not been well studied, so avoid use unless cleared by your doctor.

Breastfeeding Use caution There is little safety information for breastfeeding, so check with your doctor first.

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

What to actually watch for

No Interaction Found — But Data Suggests Magnet Therapy and Phenylephrine 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 having Magnet Therapy 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.

Nausea reported in 7.6% of FDA reports for Phenylephrine Additional detail
Magnet Therapy
“Magnet therapy seems to be generally well-tolerated. Some side effects reported in clinical trials include more painful menstrual periods, heavier periods, nausea, diarrhea, an abnormal sensation in the arms, and a feeling of "fuzzy headedness". However, it is unclear whether these side effects are attributable to the magnet therapy.”

Phenylephrine

Listed in the ADVERSE REACTIONS section of the FDA label for Phenylephrine, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Magnet Therapy but not commonly for Phenylephrine: diarrhea.

Effects for Phenylephrine come from the ADVERSE REACTIONS section of its FDA label; effects for Magnet Therapy come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 221,388 voluntary FDA FAERS reports for Phenylephrine 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.

Questions About Magnet Therapy or Phenylephrine

These are real questions from readers, answered by the pharmacists at HelloPharmacist — written by a person, not generated from a database. Each one covers Magnet Therapy or Phenylephrine, not necessarily both, but if one is close to what you were about to ask it will usually go further than a database entry can:

Everything else you take

See Every Supplement That Interacts With Phenylephrine

This page covers Magnet Therapy only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Phenylephrine page lists 81 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Ephedra (major), Lithium (major), Peyote (major) and Rauvolfia Vomitoria (major).

By severity: 6 major · 60 moderate · 15 minor.

From our pharmacist’s overview on the Phenylephrine page

“If you take phenylephrine (Sudafed PE, Biorphen) for congestion, treat this list as one that needs real attention, since six of its 81 entries carry a major rating. Phenylephrine tightens blood vessels to clear your nose, and more than half of the interactions here come from stimulant ingredients, ephedra above all, that can push blood…”

Treatment approach

About Magnet Therapy

What is Magnet Therapy?

Joint and arthritis pain
Back and neck pain
Muscle aches
Fibromyalgia and chronic pain
General wellness and circulation

Magnet therapy involves placing static magnets near the body in hopes of easing pain, but high-quality studies have not shown that it works better than fake (placebo) magnets. It is generally low-risk for most people, but it should never replace proven medical care.

Not applicable (uses static or electromagnetic magnets) · Magnetic bracelets, insoles, mattress pads, wraps, necklaces, and patches

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

Magnet Therapy: dosing

There is no established or standardized "dose" for magnet therapy. Products vary widely in magnet strength, size, and how they are worn.If you choose to try a magnetic product, follow the manufacturer's instructions for how to wear or place it.

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

About Phenylephrine

What Is Phenylephrine Used For?

Brand names: Gilchew, AH Chew D, Gilchew IR, Sudafed PE, Biorphen

Phenylephrine is used in several different products, and each one has its own use.

Injection (IV): raises blood pressure in adults with clinically important hypotension (low blood pressure) caused mainly by widened blood vessels. Some injections are labeled for anesthesia only. Others are labeled for anesthesia and septic shock.

Eye drops: Phenylephrine Hydrochloride Ophthalmic Solution is used to dilate the pupil.

Nasal products: temporarily relieve nasal and sinus congestion from the common cold, hay fever or other upper respiratory allergies.

Rectal suppositories: relieve itching, burning and discomfort from hemorrhoids and temporarily shrink hemorrhoidal tissue.

Most-Reported Side Effects for Phenylephrine

From FAERS, the FDA’s public side-effect reporting system (221,388 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 20,609 reports

Headache 17,301 reports

Nausea 16,925 reports

Diarrhea 14,221 reports

Dyspnea 13,719 reports

Having Magnet Therapy While Taking Phenylephrine: Common Questions

Is it safe to have Magnet Therapy while taking Phenylephrine?

We do not list a known interaction between Magnet Therapy and Phenylephrine. 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 Magnet Therapy and Phenylephrine 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.

Does Phenylephrine interact with any supplements?

Yes. Phenylephrine has documented interactions with 81 supplements in our database — Magnet Therapy is not one of them. The Phenylephrine interaction page linked on this page lists every one, ranked by severity.
