Poplar and Asfotase Alfa

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 Asfotase Alfa and Poplar 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 Poplar at all — not against Asfotase Alfa, 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.

Poplar safety at a glance

Poplar overall Use caution Generally used in folk medicine, but human safety data are limited and it contains aspirin-like compounds.
Pregnancy Avoid Not enough safety data and its salicylate content makes it best avoided during pregnancy.
Breastfeeding Avoid Safety during breastfeeding is unknown, so it is best avoided.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Asfotase Alfa’s Own FDA Label Lists

This is not an interaction — none of it involves Poplar. These are the most notable effects listed in the ADVERSE REACTIONS section of Asfotase Alfa’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 5 of them are worth acting on rather than waiting out — marked below.

  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • An allergic reaction Worth acting on
  • Mood changes or irritability
  • Chills
  • Flushing
  • Fever
  • Itching

Showing the 10 most notable of 15 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 Asfotase Alfa. Read the label on DailyMed › Where a percentage is shown, it is the share of 9,959 voluntary FDA FAERS reports for Asfotase Alfa that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Poplar’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Poplar side to compare — that is a limit of the record, not a statement that Poplar has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Poplar is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Poplar reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Poplar and Asfotase Alfa records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Poplar

What is Poplar?

  • Minor pain and fever
  • Arthritis and joint discomfort
  • Minor skin wounds and irritation (topical)
  • Coughs and sore throat
  • Inflammation

Poplar comes from trees in the Populus genus and has a long history in folk medicine for pain, inflammation, and minor wounds, partly because its bark and buds contain salicin (a salicylate similar to the building block of aspirin). High-quality human studies are limited, so its true effectiveness is uncertain. Talk with your pharmacist or doctor before using it, especially if you are sensitive to aspirin.

Populus spp. · Salicaceae · Bark, leaf buds (leaf bud resin), and leaves · Tea, tincture, capsules, topical salves and ointments, dried bark or buds

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

Poplar: dosing

There is no well-established standard dose for poplar. The right amount depends on the product, the part of the plant used, and how it is prepared (tea, tincture, capsule, or topical).The safest approach is to follow the directions on the product label and not exceed them.

From our Poplar monograph — the full record covers uses, side effects and every documented interaction.
