Drug & supplement interaction

Galphimia Glauca + Ketoconazole

Ketoconazole brand name: Nizoral.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Galphimia Glauca and Ketoconazole 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.

Galphimia Glauca and Ketoconazole

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 Ketoconazole and Galphimia Glauca 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.

Galphimia Glauca safety at a glance

Galphimia Glauca overall Use caution Short-term studies suggest it is generally well tolerated, but long-term safety data are limited.
Pregnancy Avoid There is not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid There is 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 Ketoconazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ketoconazole is filed under 8 classifications — including antifungals, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Galphimia Glauca has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Ketoconazole’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.

No Interaction Found — But Data Suggests Galphimia Glauca and Ketoconazole 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.

  • Drowsiness / Headache Additional detail

    Galphimia Glauca

    “Orally, Galphimia glauca extract 7-14 mg daily has been associated with sedation and headache. Rarely, restlessness, nervousness, weakness, and other side effects have been reported; but it is unclear if Galphimia glauca was the causal factor.”

See Every Supplement That Interacts With Ketoconazole

This page covers Galphimia Glauca only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ketoconazole page lists 182 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Grapefruit (major), Siberian Cocklebur (major) and St. John's Wort (major).

By severity: 6 major · 135 moderate · 41 minor.

From our pharmacist’s overview on the Ketoconazole page

“Ketoconazole (Nizoral) is already hard on the liver, so treat its 182 interacting supplements with genuine care, starting with the six rated major. Most of the list runs through CYP3A4, the liver enzyme ketoconazole strongly blocks, so it can raise levels of over a hundred herbal ingredients, while grapefruit pushes ketoconazole itself…”

Galphimia Glauca
  • Anxiety and stress
  • Insomnia
  • Allergic rhinitis and hay fever
  • Respiratory complaints
  • Traditionally used as an anticonvulsant

Galphimia glauca is a shrub from Mexico and Central America that has been studied mainly for anxiety, with some small clinical trials suggesting possible benefit.

Galphimia glauca · Malpighiaceae · Leaves and aerial parts · Capsules, standardized extracts, tinctures, homeopathic preparations, tea

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

Galphimia Glauca: dosing

There is no well-established standard dose of Galphimia glauca. Clinical studies have used standardized extracts, but products on the market vary widely in their strength and how they are made.Because of this, follow the directions on the product label and do not exceed the recommended amount.

About Ketoconazole

What Is Ketoconazole Used For?

Brand name: Nizoral

Ketoconazole 2% shampoo and foam are used to treat tinea versicolor (also called pityriasis versicolor) — a fungal infection caused by Pityrosporum orbiculare (also known as Malassezia furfur), a yeast that naturally lives on the skin.

This infection creates light or dark patches, most often on the trunk, neck, arms, and upper thighs. Even after the fungus is cleared, those skin patches may take months to return to their normal color — that's normal, and depends on your skin type and sun exposure. Tinea versicolor can also come back, since the fungus lives on healthy skin even when there's no active infection.

Most-Reported Side Effects for Ketoconazole

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Galphimia Glauca and Ketoconazole Together: Common Questions

Is it safe to take Galphimia Glauca with Ketoconazole?
We do not list a known interaction between Galphimia Glauca and Ketoconazole. 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 Galphimia Glauca and Ketoconazole have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other.

How was the Galphimia Glauca and Ketoconazole combination checked?
Interactions in our licensed database are recorded against drug classes. Ketoconazole is filed under 8 classifications, and Galphimia Glauca has documented interactions with 1 drug class — none of Ketoconazole'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 Galphimia Glauca interact with any other medications?
Yes. Galphimia Glauca has 248 documented drug interactions in our database — Ketoconazole is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
