The bottom line No known interaction

We found no known interaction between Phellodendron and Sulfacetamide 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.

Phellodendron and Sulfacetamide

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 Sulfacetamide and Phellodendron 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.

Phellodendron safety at a glance

Phellodendron overall Use caution Generally used short-term in traditional medicine, but human safety data are limited.

How we checked

Why No Interaction Is Listed for Sulfacetamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sulfacetamide is filed under a single classification — photosensitizing drugs. Phellodendron has documented interactions with 14 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and antihypertensive drugs (moderate) — and none of Sulfacetamide’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 Phellodendron Itself Has Been Linked To

This is not an interaction — nothing below involves Sulfacetamide. It is the side-effect record for Phellodendron on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Phellodendron, this list is the first place to look.

  • Heartburn Additional detail

    “Orally, a combination product containing extracts of phellodendron plus magnolia has been associated with one report of heartburn in one clinical trial. However, it is unknown if this is related to phellodendron or some other factor.”

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

About Phellodendron

What is Phellodendron?

Phellodendron
  • Digestive complaints and diarrhea
  • Inflammation and joint discomfort
  • Stress and weight management (in combination products)
  • Skin conditions (topical, traditional)
  • Antimicrobial support

Phellodendron is a traditional Chinese medicine bark (Huang Bai) that contains berberine and other plant compounds with antimicrobial and anti-inflammatory activity in lab studies. Human evidence for most uses is limited, and it is often sold in combination with other herbs, making its individual effects hard to judge. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Phellodendron amurense · Rutaceae · Bark (cortex) · Capsules, tablets, powders, tinctures, and dried bark used in teas or decoctions; often combined with other herbs

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

Phellodendron: dosing

There is no well-established, standardized dose of Phellodendron for any health condition. Products vary widely in strength and may contain other herbs, which makes general dosing advice difficult.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount.

About Sulfacetamide Ophthalmic

What Is Sulfacetamide Ophthalmic Used For?

Brand name: AK-Sulf

Sulfacetamide Sodium Ophthalmic Solution 10% (eye drops) treats conjunctivitis (often called pink eye) and other superficial eye infections caused by susceptible bacteria. It is also used as an add-on to sulfonamide medicine given through the body for trachoma.

It does not cover every germ. Sulfa drugs used on the eye do not adequately cover Neisseria species, Serratia marcescens or Pseudomonas aeruginosa. Many staph strains are completely resistant to sulfa drugs.

Most-Reported Side Effects for Sulfacetamide

From FAERS, the FDA’s public side-effect reporting system (736 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
