Drug & supplement interaction

Mormon Tea + Mexiletine

Mexiletine brand name: Mexitil.

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 Mormon Tea and Mexiletine 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 Mexiletine 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.

Interaction report

Mormon Tea and Mexiletine

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 Mexiletine and Mormon Tea 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Mormon Tea at all — not against Mexiletine, 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.

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.

Mormon Tea safety at a glance

Mormon Tea overall Use caution Generally considered milder than Asian ephedra, but human safety data are limited.
Pregnancy Avoid Not enough safety information, and ephedra-related plants are best avoided during pregnancy.
Breastfeeding Avoid There is no reliable safety data, so avoid use while breastfeeding.

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 Mormon Tea and Mexiletine 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.

  • Stomach upset / Constipation Additional detail

How to take them

Some Mexiletine Products Have a Food Rule — Mormon Tea Should Not Break It

At least one FDA label for a product containing Mexiletine says to take it with food. If you take Mormon Tea on an empty stomach out of habit, keep them separate — and take Mexiletine 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 Mexiletine 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.

Administration with food or antacid is recommended.

From the Dosage and Administration section of the FDA label we read for Mexiletine — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Mexiletine

This page covers Mormon Tea only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mexiletine page lists 152 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), 1,3-dmaa (moderate), Acacia Rigidula (moderate), Active Hexose Correlated Compound (ahcc) (moderate) and Adrafinil (moderate).

By severity: 1 major · 107 moderate · 44 minor.

From our pharmacist’s overview on the Mexiletine page

“Mexiletine (Mexitil) steadies the heart's rhythm, and its benefit depends on holding a fairly precise blood level, so the 152 supplements on this list deserve real attention rather than a shrug. Only one entry, activated charcoal, is rated major, because it can soak up the drug in the gut and cut how much actually reaches your bloodstr…”

About Mormon Tea

What is Mormon Tea?

  • Caffeine-free beverage
  • Kidney and urinary complaints
  • Cold and congestion relief
  • Mild digestive upset
  • General tonic

Mormon Tea is a traditional Southwestern desert beverage made from a North American Ephedra plant that, unlike Asian ephedra, is generally thought to lack ephedrine. There is very little modern scientific evidence to support any specific health benefit, so it is mostly used as a mild, caffeine-free herbal drink. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a medical condition.

Ephedra nevadensis · Ephedraceae · Dried stems and twigs · Tea (dried herb), capsules, loose dried stems

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

Mormon Tea: dosing

There is no established standardized dose for Mormon Tea. Traditionally, a small amount of dried stems is steeped in hot water and drunk as a tea, but the strength of homemade or commercial products can vary widely.If you choose to use it, follow the directions on the product label and do not exceed them. Because the active content is uncertain, start low and avoid frequent or large amounts.

About Mexiletine

What Is Mexiletine Used For?

Brand name: Mexitil

Mexiletine Hydrochloride capsules are indicated for the treatment of documented, life-threatening ventricular arrhythmias — for example, sustained ventricular tachycardia (a dangerously fast heart rhythm originating in the lower chambers). Because mexiletine itself can trigger arrhythmias, it is not recommended for minor or symptom-free irregular heartbeats.

Treatment is started in a hospital setting so heart rhythm can be monitored closely. Antiarrhythmic drugs, including mexiletine, have not been shown to improve overall survival in patients with ventricular arrhythmias.

Taking Mormon Tea and Mexiletine Together: Common Questions

Is it safe to take Mormon Tea with Mexiletine?
We do not list a known interaction between Mormon Tea and Mexiletine. 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 Mormon Tea and Mexiletine 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.
Should I take Mormon Tea and Mexiletine at the same time of day?
At least one FDA label for a product containing Mexiletine says to take it with food. If you take Mormon Tea on an empty stomach out of habit, keep them separate and take Mexiletine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Mexiletine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Mexiletine interact with any supplements?
Yes. Mexiletine has documented interactions with 152 supplements in our database — Mormon Tea is not one of them. The Mexiletine interaction page linked on this page lists every one, ranked by severity.
