The bottom line No known interaction

We found no known interaction between Coltsfoot and Docusate 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.

Coltsfoot and Docusate

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 Docusate and Coltsfoot 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 Docusate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Docusate is filed under a single classification — oral drugs. Coltsfoot has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antihypertensive drugs (moderate) and cytochrome p450 3a4 (cyp3a4) inducers (moderate) — and none of Docusate’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.

What to actually watch for

What Coltsfoot Itself Has Been Linked To

This is not an interaction — nothing below involves Docusate. It is the side-effect record for Coltsfoot on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Coltsfoot, this list is the first place to look. 3 entries are worth acting on rather than waiting out — marked below.

  • Blood clots Worth acting on Additional detail

    “Orally, the major concern with coltsfoot use is its pyrrolizidine alkaloid (PA) content. These alkaloids can cause liver and lung injury. Chronic exposure to other plants containing hepatotoxic PA constituents has been associated with hepatic veno-occlusive disease. Sub-acute veno-occlusive disease can cause vague symptoms, including colicky pains, vomiting, diarrhea, and ascites within several days;”

    “Orally, a single case report associates coltsfoot and its PA content with deep vein thrombosis (DVT) and pulmonary embolus (PE). A 27-year-old man with no history of coagulation disorders developed a DVT and several PE after consuming unknown quantities of coltsfoot and several other herbs. However, he also had other risk factors for thrombosis, including smoking and recent bed rest.”

Special populations

Coltsfoot in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

When products containing hepatotoxic pyrrolizidine alkaloid (PA) constituents are used orally. Coltsfoot preparations containing hepatotoxic pyrrolizidine alkaloid (PA) constituents might be teratogenic and hepatotoxic. There is one case report of fatal hepatic veno-occlusive disease in a neonate associated with regular maternal consumption during pregnancy of an herb tea containing several pyrrolizidine alkaloid herbs, including coltsfoot. There is insufficient reliable information available about the safety of using coltsfoot products certified and labeled as hepatotoxic PA-free during pregnancy; avoid using.

Lactation Likely Unsafe

When used orally. Hepatotoxic pyrrolizidine alkaloid (PA) constituents in coltsfoot are excreted in milk. There is insufficient reliable information available about the safety of using coltsfoot products certified and labeled as hepatotoxic PA-free during lactation; avoid using.

About Coltsfoot

What is Coltsfoot?

Coltsfoot
  • Cough
  • Sore throat
  • Bronchitis and congestion
  • Loosening mucus (expectorant)
  • Asthma symptoms

Coltsfoot is a traditional herb long used to soothe coughs and clear mucus, but solid human evidence for these uses is lacking. More importantly, the raw plant can contain liver-toxic pyrrolizidine alkaloids, so it carries real safety concerns and is best avoided unless you use a product certified to be free of these compounds.

Tussilago farfara · Asteraceae · Leaves and flowers · Tea, dried herb, tincture, syrup, capsules, lozenges

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

Coltsfoot: dosing

There is no established, standardized dose for coltsfoot, and because of the safety concerns, no dose can be considered clearly safe. Traditional products include teas, syrups, and tinctures, but the amount of active and toxic compounds can vary widely between products.If you choose to use coltsfoot despite the risks, only use a product certified to be free of pyrrolizidine alkaloids, follow the label directions exactly, and use it for the shortest time possible.
