Buck's-horn Plantain and Apremilast

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 Apremilast and Buck's-horn Plantain 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 Buck's-horn Plantain at all — not against Apremilast, 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.

What Apremilast’s Own FDA Label Lists

This is not an interaction — none of it involves Buck's-horn Plantain.

Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 3 of them are worth acting on rather than waiting out — marked below.

  • Low mood Worth acting on
  • A higher chance of infection Worth acting on

Showing the 10 most notable of 19 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Apremilast. Read the label on DailyMed › Where a percentage is shown, it is the share of 145,481 voluntary FDA FAERS reports for Apremilast that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Buck's-horn Plantain’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Buck's-horn Plantain side to compare — that is a limit of the record, not a statement that Buck's-horn Plantain has no side effects.

About Buck's-horn Plantain

What is Buck's-horn Plantain?

  • Eaten as a leafy salad green
  • Digestive complaints
  • Soothing irritated skin (topical, traditional)
  • Mild diuretic (traditional)
  • General tonic in folk medicine

Buck's-horn plantain (Plantago coronopus) is mainly a edible coastal salad green that has also been used in folk medicine for digestion and minor skin or urinary complaints. There is very little human research to support any medicinal use, so it should be viewed as a nutritious food rather than a proven remedy. If you want to use it for a health condition, talk with a pharmacist or doctor first.

Plantago coronopus · Plantaginaceae · Leaves (and sometimes seeds) · Fresh leaves (as a salad green or potherb), dried herb, tea/infusion, occasionally poultices
