1-epiandrosterone 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 1-epiandrosterone 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 1-epiandrosterone 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.

What Omeprazole’s Own FDA Label Lists

This is not an interaction — none of it involves 1-epiandrosterone. These are the most notable effects listed in the ADVERSE REACTIONS section of Omeprazole’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. 5 of them are worth acting on rather than waiting out — marked below.

  • Kidney problems Worth acting on mentioned in 13.6% of FDA reports for Omeprazole
  • Low magnesium Worth acting on
  • Bone thinning Worth acting on
  • Bleeding in the gut Worth acting on
  • A higher chance of infection Worth acting on
  • Bloating or gas
  • Back pain
  • Cough
  • Fever
  • Constipation

From the ADVERSE REACTIONS section of the FDA label for Omeprazole. Read the label on DailyMed › 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. 1-epiandrosterone’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no 1-epiandrosterone side to compare — that is a limit of the record, not a statement that 1-epiandrosterone has no side effects.

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 1-epiandrosterone

What is 1-epiandrosterone?

1-epiandrosterone
  • Muscle building
  • Athletic performance
  • Improving body composition
  • Strength gains

1-epiandrosterone (often sold as a '1-andro' prohormone) is a steroid-related compound marketed to bodybuilders for muscle and strength gains, but solid human evidence is very limited and the safety profile is poorly understood. Because it can act like an anabolic steroid in the body and may carry liver, hormonal, and cardiovascular risks, most people should avoid it and talk to a pharmacist or doctor first.

Not a plant; a synthetic or lab-made steroid compound (prohormone) · Capsules, tablets, sometimes part of multi-ingredient bodybuilding 'prohormone' supplements

An interaction check asks whether these two react with each other — it does not ask whether 1-epiandrosterone is a good idea for someone in your situation. Here is what our 1-epiandrosterone record says about it on its own.

1-epiandrosterone: dosing

There is no established safe or effective dose for 1-epiandrosterone. Because these products can act like steroids and may carry real risks, do not assume "more is better." The safest choice for most people is to avoid it.

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
