Drug & supplement interaction

Goldenrod + Filgrastim

Filgrastim brand name: Neupogen.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Goldenrod and Filgrastim 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.

Goldenrod and Filgrastim

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 Filgrastim and Goldenrod 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.

Goldenrod safety at a glance

Goldenrod overall Use caution Often well tolerated short-term, but human safety data are limited and allergy is possible.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety information, so it is best avoided while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Filgrastim

Interactions in our licensed database are recorded against drug classes, not just single drug names. Filgrastim is filed under a single classification — oral drugs. Goldenrod has documented interactions with 1 drug class — the most serious being diuretic drugs (moderate) — and none of Filgrastim’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 to actually watch for

No Interaction Found — But Data Suggests Goldenrod and Filgrastim May Share Several of the Same Side Effects

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. One of them is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    Goldenrod

    “Environmental exposure to goldenrod has been reported to cause a delayed allergic reaction involving rhinoconjunctivitis and bronchial asthma in one case report of a 42 year-old woman who worked at a flower shop and was exposed to members of the Asteraceae/Compositae family, including goldenrod.”

    Filgrastim

    Listed in the ADVERSE REACTIONS section of the FDA label for Filgrastim. Read the label on DailyMed ›

Reported for Goldenrod but not commonly for Filgrastim: wheezing.

Effects for Filgrastim come from the ADVERSE REACTIONS section of its FDA label; effects for Goldenrod come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 41,970 voluntary FDA FAERS reports for Filgrastim 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.

Everything else you take

See Every Supplement That Interacts With Filgrastim

This page covers Goldenrod only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Filgrastim page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Filgrastim page

“Filgrastim (Neupogen) is an injection that raises white blood cell counts, most often to protect people on chemotherapy from infection, and the 17 supplements on file with it deserve real attention rather than a shrug. Nearly all are fibers, gums, and mucilage-rich herbs that can blunt how medicines taken by mouth get absorbed.”

About Goldenrod

What is Goldenrod?

  • Urinary tract health
  • Mild bladder or kidney support
  • Inflammation
  • Sore throat and mouth rinse
  • Wound care (traditional)

Goldenrod is a flowering plant traditionally used as an herbal diuretic and for urinary tract health. Human evidence is limited, and while it is generally well tolerated, people with certain allergies, kidney problems, or who are pregnant or breastfeeding should be cautious. Talk with a pharmacist or doctor before using it.

Solidago virgaurea · Asteraceae · Aerial parts (flowers, leaves, and stems) · Tea, tincture, liquid extract, capsules, dried herb

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

Goldenrod: dosing

There is no well-established standardized dose for goldenrod, and the right amount can vary widely depending on the product, the species used, and the form (tea, tincture, or capsule).Because of this, the best approach is to follow the directions on the product label and not exceed the recommended amount.

About Filgrastim Injection

What Is Filgrastim Injection Used For?

Brand name: Neupogen

Filgrastim injection (available as Neupogen, Nivestym, and Releuko) is used to lower the risk of serious infection in people whose white blood cell counts drop dangerously low. This can happen during chemotherapy for cancer, during treatment for acute myeloid leukemia (AML), or after bone marrow transplantation. It is also used to help move stem cells from the bone marrow into the bloodstream so they can be collected for transplantation.

In addition, filgrastim is used long-term to reduce infections in people with severe chronic neutropenia — including congenital neutropenia, cyclic neutropenia, and idiopathic neutropenia. Neupogen is also indicated to increase survival in patients acutely exposed to radiation doses that suppress the bone marrow (Hematopoietic Syndrome of Acute Radiation Syndrome).

Most-Reported Side Effects for Filgrastim

From FAERS, the FDA’s public side-effect reporting system (41,970 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Febrile neutropenia 4,555 reports
Neutropenia 3,641 reports
Fever 3,033 reports
Diarrhea 2,461 reports
Nausea 2,206 reports

Taking Goldenrod and Filgrastim Together: Common Questions

Is it safe to take Goldenrod with Filgrastim?
We do not list a known interaction between Goldenrod and Filgrastim. 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 Goldenrod and Filgrastim have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
How was the Goldenrod and Filgrastim combination checked?
Interactions in our licensed database are recorded against drug classes. Filgrastim is filed under 1 classification, and Goldenrod has documented interactions with 1 drug class — none of Filgrastim's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Goldenrod interact with any other medications?
Yes. Goldenrod has 75 documented drug interactions in our database — Filgrastim is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Filgrastim interact with any supplements?
Yes. Filgrastim has documented interactions with 17 supplements in our database — Goldenrod is not one of them. The Filgrastim interaction page linked on this page lists every one, ranked by severity.
