We found no known interaction between Tragacanth and Certolizumab 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.

Tragacanth and Certolizumab

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 Certolizumab and Tragacanth 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.

Tragacanth overall Use caution Generally recognized as safe in food amounts, but quality and purity of supplements can vary.

What to actually watch for

What Tragacanth Itself Has Been Linked To

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

  • Wheezing Worth acting on Additional detail

    “Tragacanth can cause asthma symptoms in people who are sensitive to quillaia bark (6).”

Everything above comes from the Natural Medicines adverse-effect record for Tragacanth — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Certolizumab’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Certolizumab column appears here.

Overlapping uses

What Certolizumab Is Prescribed For, and What Tragacanth Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Certolizumab is a prescription medicine with approved uses on its FDA label. Tragacanth is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Certolizumab is prescribed for: Cimzia is used to treat several inflammatory conditions in adults: moderately to severely active Crohn's disease (in adults who haven't responded well to standard therapy), moderately to severely active rheumatoid arthritis, active psoriatic arthritis, active ankylosing spondylitis, active non-radiographic axial spondyloarthritis with signs of inflammation, and moderate-to-severe plaque psoriasis in adults who need systemic treatment or phototherapy. Cimzia is also approved to treat active polyarticular juvenile idiopathic arthritis (pJIA) in patients 2 years of age and older — one of its few pediatric uses. Effectiveness for Crohn's disease in children and adolescents was not demonstrated in clinical study.

Tragacanth has been studied for:

  • Diarrhea studied, not established Tragacanth has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Tragacanth for diarrhea

    Although there is interest in using oral tragacanth for diarrhea, there is insufficient reliable information about the clinical effects of tragacanth for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Certolizumab on your own; if you are taking Tragacanth for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Tragacanth

What is Tragacanth?

Tragacanth
  • Soothing sore throat and cough
  • Digestive upset and constipation
  • Thickening or binding agent in products
  • Skin soothing in creams and pastes

Tragacanth is a plant gum used mainly as a thickener and emulsifier in foods, cosmetics, and medicines, and traditionally to soothe the throat and gut. There is very little solid human research showing it treats any specific condition. It is generally considered safe in food amounts, but anyone with allergies or who is pregnant or breastfeeding should check with a pharmacist or doctor first.

Astragalus gummifer · Fabaceae · Dried gummy sap (exudate) from the stems and branches · Powder, paste, capsules, lozenges, and as an additive (thickener or binder) in foods, lotions, and medicines

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

Tragacanth: dosing

There is no well-established standardized medicinal dose for tragacanth. The amounts used in foods and medicines are usually small and act as thickeners rather than active treatments.If you choose to use a tragacanth product, follow the directions on the label and take any powder with plenty of water.

Taking Tragacanth and Certolizumab Together: Common Questions

Is it safe to take Tragacanth with Certolizumab?
We do not list a known interaction between Tragacanth and Certolizumab. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Are Tragacanth and Certolizumab used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Tragacanth in each. That is a conversation for your prescriber, especially if Certolizumab is being adjusted to a target.
Does Tragacanth interact with any other medications?
Yes. Tragacanth has 2,022 documented drug interactions in our database — Certolizumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
