The bottom line No known interaction

We found no known interaction between Peppermint and acetaminophen, dextromethorphan, doxylamine 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.

Interaction report

Peppermint and acetaminophen, dextromethorphan, doxylamine

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 acetaminophen, dextromethorphan, doxylamine and Peppermint 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.

Pharmacist analysis

Peppermint and peppermint oil have a number of theoretical interactions due to several lab and animal studies suggesting it can inhibit a variety of CYP metabolizing enzymes in the liver, including:

CYP2C9
CYP3A4
CYP2C19
CYP1A2

However, many of these interactions have not been seen in humans, and the likelihood of them being clinically significant is low. They are nevertheless important to be aware of.

There is no known interaction between peppermint and the drug in question here. They are considered safe to combine.

How we checked

Why No Interaction Is Listed for acetaminophen, dextromethorphan, doxylamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. acetaminophen, dextromethorphan, doxylamine is filed under 4 classifications — including cns depressants, oral drugs. Peppermint has documented interactions with 5 drug classes — the most serious being cyclosporine (neoral, sandimmune) (moderate), cytochrome p450 2c19 (cyp2c19) substrates (moderate) and cytochrome p450 2c9 (cyp2c9) substrates (moderate) — and none of acetaminophen, dextromethorphan, doxylamine’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

This is not an interaction — nothing below involves acetaminophen, dextromethorphan, doxylamine. It is the side-effect record for Peppermint on its own, from the licensed Natural Medicines monograph.

About Peppermint

What is Peppermint?

Irritable bowel syndrome (IBS)
Indigestion and gas
Nausea
Tension headache (topical oil)
Colds and congestion
Freshening breath

Peppermint is a popular herb with the best evidence supporting enteric-coated peppermint oil for easing IBS symptoms. It is generally well tolerated for most adults, but it can cause heartburn and is not recommended in concentrated oil form for infants and young children. Check with your pharmacist or doctor before using it regularly, especially during pregnancy or breastfeeding.

Mentha x piperita · Lamiaceae · Leaves and essential oil · Tea, capsules (including enteric-coated peppermint oil), essential oil, tincture, topical creams

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

Peppermint: dosing

There is no single official dose for peppermint, and the right amount depends on the form and the reason you are using it. For IBS, products usually come as standardized enteric-coated peppermint oil capsules with directions on the label. Teas are made by steeping the dried leaves in hot water.Because product strength varies widely, the best approach is to follow the directions on your specific product and not to exceed the recommended amount. Concentrated essential oil should never be swallowed unless it is in a product made for that purpose.
