Goa Powder + Omeprazole

Omeprazole brand names: Prilosec, Zegerid, Losec.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Goa Powder and Omeprazole 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.

Goa Powder and Omeprazole

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 Omeprazole and Goa Powder 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 Goa Powder at all — not against Omeprazole, 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 Goa Powder and Omeprazole 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.

  • Diarrhea / Vomiting reported in 5.7% of FDA reports for Omeprazole Additional detail

Reported for Goa Powder but not commonly for Omeprazole: swelling.

Effects for Omeprazole come from the ADVERSE REACTIONS section of its FDA label; effects for Goa Powder come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 448,293 voluntary FDA FAERS reports for Omeprazole 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.

From our pharmacist’s overview on the Omeprazole page

“Omeprazole (Prilosec, Zegerid, Losec) is an acid reducer for heartburn, reflux, and ulcers, and because it sits on pharmacy shelves next to the vitamins, people tend to assume it mixes safely with anything. This list argues otherwise, and it warrants genuine care.”

About Goa Powder

What is Goa Powder?

  • Psoriasis (topical)
  • Ringworm and other fungal skin infections
  • Scaly skin conditions
  • Eczema-like rashes

Goa powder (also called araroba) is a natural source of chrysarobin, a substance historically used on the skin for psoriasis and fungal infections. It is a harsh, irritating chemical that is mostly of historical interest today, and it should never be swallowed. If you are considering anything containing chrysarobin or anthralin, talk with a doctor or pharmacist first.

Andira araroba · Fabaceae · A yellow powder (chrysarobin) extracted from the wood and trunk cavities of the araroba tree · Topical ointments, pastes, and creams; historically a raw powder

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

Goa Powder: dosing

There is no established or standardized dose for Goa powder as a supplement. Historically it was mixed into ointments at concentrations chosen by a pharmacist or physician, and even then it had to be used carefully because of irritation and staining.If you encounter a product that contains chrysarobin or the related medicine anthralin, follow the product label exactly and do not apply more than directed. Because this is a potent and irritating substance, it is best to use it only under the guidance of a doctor or pharmacist.

About Omeprazole

What Is Omeprazole Used For?

Brand names: Prilosec, Zegerid, Losec

Omeprazole is used to treat a range of conditions where stomach acid causes problems. These include heartburn and acid reflux (GERD), erosive esophagitis (damage to the esophagus from acid), and stomach or duodenal ulcers. It can also be used alongside antibiotics to help get rid of an H. pylori infection — a bacteria that causes ulcers.

In more serious cases, omeprazole is used to manage conditions where the stomach produces far too much acid, such as pathologic hypersecretory conditions (rare medical disorders that cause extreme acid overproduction). It is approved for adults and children one year of age and older for GERD and erosive esophagitis.

Most-Reported Side Effects for Omeprazole

From FAERS, the FDA’s public side-effect reporting system (448,293 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Chronic kidney disease 36,807 reports
Nausea 27,095 reports
Fatigue 26,259 reports
Diarrhea 25,668 reports
Acute kidney injury 23,964 reports

Taking Goa Powder and Omeprazole Together: Common Questions

Is it safe to take Goa Powder with Omeprazole?
We do not list a known interaction between Goa Powder and Omeprazole. 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 Goa Powder and Omeprazole 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.
Does Omeprazole interact with any supplements?
Yes. Omeprazole has documented interactions with 174 supplements in our database — Goa Powder is not one of them. The Omeprazole interaction page linked on this page lists every one, ranked by severity.
