The bottom line No known interaction

We found no known interaction between Tannic Acid and Triamcinolone 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Tannic Acid and Triamcinolone

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 Triamcinolone and Tannic Acid 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 Tannic Acid at all — not against Triamcinolone, 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.

No Interaction Found — But Data Suggests Tannic Acid and Triamcinolone May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Nausea reported in 6.6% of FDA reports for Triamcinolone Additional detail

    Tannic Acid

    “Orally, large amounts of tannic acid can cause gastric irritation, nausea, and vomiting (11). Extensive use of tannins on burns or in enemas has been associated with fatal liver damage (11). However, this toxicity may be due to digallic acid, an impurity that is sometimes found in tannic acid (11).”

    Triamcinolone

    Listed in the ADVERSE REACTIONS section of the FDA label for Triamcinolone, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Tannic Acid but not commonly for Triamcinolone: stomach upset, liver problems and vomiting.

Effects for Triamcinolone come from the ADVERSE REACTIONS section of its FDA label; effects for Tannic Acid come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 30,525 voluntary FDA FAERS reports for Triamcinolone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Special populations

Tannic Acid in Pregnancy & Breastfeeding

Pregnancy And Lactation Possibly Unsafe

When used topically on damaged or broken skin. There is insufficient reliable information available about the safety of tannic acid when used orally during pregnancy and lactation; avoid using amounts greater than those found in foods.

About Tannic Acid

What is Tannic Acid?

  • Minor skin irritation and weeping rashes
  • Sore throat and mouth sores
  • Minor burns and blisters
  • Astringent for skin
  • Hemorrhoids

Tannic acid is a plant-derived astringent used mostly on the skin and in the mouth to dry out and tighten tissue. There is some traditional and topical use, but high-quality evidence for most uses is limited, and it can be harmful if too much is absorbed, especially on broken skin or burns.

Tannins extracted from plant sources such as oak galls, bark, and certain seeds and leaves · Topical powders and solutions, throat lozenges, gargles, suppositories, and some over-the-counter skin products

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

Tannic Acid: dosing

There is no well-established standard dose of tannic acid for supplement use. The amount varies widely depending on the product and how it is used (for example, a skin solution versus a lozenge).The safest approach is to follow the directions on the product label and not apply it to large areas of broken or burned skin.

About Triamcinolone

What Is Triamcinolone Used For?

Brand names: Aristocort, Kenacort, Adcortyl Intra-articular / Intradermal, Kenalog Intra-articular / Intramuscular, Adcortyl in Orabase, Triesence

Triamcinolone is available in many forms — injections, creams, ointments, nasal sprays, dental pastes, and eye injections — each approved for specific uses. Injectable forms given into muscle are used when oral steroids aren't an option, covering severe allergies (like asthma flares, severe skin reactions, drug reactions, and serum sickness), serious skin diseases, certain endocrine (hormonal) disorders, and more.

Injections given directly into a joint (intra-articular) or soft tissue help with conditions like rheumatoid arthritis, gout flares, bursitis, and tendon inflammation. Injections into skin lesions (intralesional) treat conditions such as keloids, alopecia areata, and psoriatic plaques. Triesence (an ophthalmic injection) is specifically indicated for eye conditions like uveitis and temporal arteritis, and for visualization during eye surgery. Topical creams, ointments, lotions, and sprays relieve itching and inflammation from corticosteroid-responsive skin conditions. Dental paste forms (Oralone, Kourzeq) treat painful mouth sores from injury. Nasal sprays temporarily relieve hay fever and upper respiratory allergy symptoms such as runny nose, sneezing, and congestion.

Taking Tannic Acid and Triamcinolone Together: Common Questions

Is it safe to take Tannic Acid with Triamcinolone?
We do not list a known interaction between Tannic Acid and Triamcinolone. 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.
Do Tannic Acid and Triamcinolone have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Triamcinolone interact with any supplements?
Yes. Triamcinolone has documented interactions with 124 supplements in our database — Tannic Acid is not one of them. The Triamcinolone interaction page linked on this page lists every one, ranked by severity.
