Alchemilla and Acetaminophen, Dextromethorphan, Pseudoephedrine

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, Pseudoephedrine and Alchemilla 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 Acetaminophen, Dextromethorphan, Pseudoephedrine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Acetaminophen, Dextromethorphan, Pseudoephedrine is filed under 16 classifications — including cytochrome p450 2e1 (cyp2e1) substrates, glucuronidated drugs, alpha-adrenergic agonists. Alchemilla has documented interactions with 1 drug class — the most serious being topical drugs (minor) — and none of Acetaminophen, Dextromethorphan, Pseudoephedrine’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.

From our pharmacist’s overview on the Acetaminophen, Dextromethorphan, Pseudoephedrine page

“Ephedra is the ingredient to notice first here. Pseudoephedrine, the decongestant in Tylenol Flu, Alka-Seltzer PLUS Flu, and other acetaminophen, dextromethorphan, and pseudoephedrine combinations, is itself a stimulant, and 44 entries push the same direction, raising the odds of high blood pressure and a racing heart.”

About Alchemilla

What is Alchemilla?

Alchemilla
  • Menstrual and women's health complaints
  • Diarrhea and digestive upset
  • Wound healing (topical)
  • Skin moisturizing (topical)
  • Mild inflammation

Alchemilla (lady's mantle) is a European herb traditionally used for digestive complaints, women's health issues, and as an astringent for skin and wounds. Solid human research is very limited, so its benefits remain largely unproven, and it should be avoided in pregnancy and breastfeeding due to a lack of safety data.

Alchemilla vulgaris · Rosaceae · Above-ground parts (leaves and flowering tops) · Tea, tincture, dried herb, capsules, topical gels and creams

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

Alchemilla: dosing

There is no well-established or standardized dose for Alchemilla, because it has not been studied enough in clinical trials. Traditional use often involves a tea made from the dried herb or a tincture, and topical products are applied to the skin.The best approach is to follow the directions on the product label and not exceed the recommended amount.
