Black Alder and Pegloticase

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 Pegloticase and Black Alder 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.

Black Alder safety at a glance

Black Alder overall Use caution Limited safety data exist and it may cause nausea or stomach upset, so use cautiously and briefly.
Pregnancy Avoid There is not enough safety information, so it is best avoided during pregnancy.

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

How we checked

Why No Interaction Is Listed for Pegloticase

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pegloticase is filed under a single classification — antigout drugs. Black Alder has documented interactions with 2 drug classes — the most serious being cisplatin (platinol-aq) (moderate) and doxorubicin (adriamycin, others) (moderate) — and none of Pegloticase’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 Pegloticase’s Own FDA Label Lists

This is not an interaction — none of it involves Black Alder. These are the most notable effects listed in the ADVERSE REACTIONS section of Pegloticase’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. 9 of them are worth acting on rather than waiting out — marked below.

  • Heart failure Worth acting on
  • High blood sugar Worth acting on
  • An irregular heartbeat Worth acting on
  • Chest pain Worth acting on
  • Low mood Worth acting on
  • Kidney problems Worth acting on
  • Raised blood pressure Worth acting on
  • A severe allergic reaction Worth acting on
  • Bleeding or bruising Worth acting on
  • Heartburn

Showing the 10 most notable of 17 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 Pegloticase. Read the label on DailyMed › Where a percentage is shown, it is the share of 3,424 voluntary FDA FAERS reports for Pegloticase that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Black Alder’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Black Alder side to compare — that is a limit of the record, not a statement that Black Alder has no side effects.

See Every Supplement That Interacts With Pegloticase

This page covers Black Alder only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Pegloticase page lists 1 supplement it has a documented interaction with, worst first, each one explained.

The most serious there right now: Inosine (moderate).

By severity: 1 moderate.

From our pharmacist’s overview on the Pegloticase page

“Inosine is the one supplement on record that can work against pegloticase (Krystexxa), the IV enzyme infused for severe gout that has stopped responding to standard treatment. Inosine raises uric acid in the blood and urine, which is precisely what pegloticase exists to lower, so combining the two could blunt the very benefit those inf…”

About Black Alder

What is Black Alder?

Black Alder
  • Sore throat and mouth inflammation
  • Skin wounds and irritation (topical)
  • Fever and general aches (traditional)
  • Digestive complaints
  • Astringent for minor bleeding

Black Alder is a European tree whose bark and leaves have a long history in folk medicine, mainly as an astringent gargle or wound wash. There is very little modern human research to confirm any of these uses, and it can cause stomach upset, so it should be used cautiously and avoided during pregnancy and breastfeeding.

Alnus glutinosa · Betulaceae · Bark, leaves, and sometimes the catkins · Dried bark or leaf for tea, decoctions, tinctures, and gargles or mouth rinses

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

Black Alder: dosing

There is no established, standardized dose for Black Alder. Traditional use involved making a tea or decoction from the dried bark or leaves, or using a diluted preparation as a gargle or skin wash.If you choose to use a product, follow the directions on the label and do not exceed the recommended amount.

About Pegloticase Injection

What Is Pegloticase Injection Used For?

Brand name: Krystexxa

Krystexxa is used to treat chronic gout in adults whose gout has not responded to conventional treatments — either because standard uric-acid-lowering medications (like xanthine oxidase inhibitors) haven't brought uric acid to a normal level, or because those drugs cannot be used.

Krystexxa is not recommended for people who have high uric acid levels but no gout symptoms (a condition called asymptomatic hyperuricemia).

Most-Reported Side Effects for Pegloticase

From FAERS, the FDA’s public side-effect reporting system (3,686 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Gout 562 reports
Blood uric acid increased 405 reports
Infusion related reaction 365 reports
Therapeutic response decreased 240 reports
Dyspnea 180 reports
