The bottom line No known interaction

We found no known interaction between Adrenal Extract and Famotidine 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.

Adrenal Extract and Famotidine

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 Famotidine and Adrenal Extract 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 Adrenal Extract at all — not against Famotidine, 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 Famotidine’s Own FDA Label Lists

This is not an interaction — none of it involves Adrenal Extract. These are the most notable effects listed in the ADVERSE REACTIONS section of Famotidine’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Severe muscle breakdown Worth acting on
  • Hallucinations Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Wheezing Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on

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

Everything else you take

See Every Supplement That Interacts With Famotidine

This page covers Adrenal Extract only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Famotidine page lists 41 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), African Wild Potato (moderate), Banderol (moderate), Beer (moderate) and Biofeedback (moderate).

By severity: 1 major · 19 moderate · 21 minor.

From our pharmacist’s overview on the Famotidine page

“Famotidine (Pepcid) treats heartburn and acid reflux, a low-stakes job most days, but its interaction list earns genuine caution because one entry is rated major. That entry is activated charcoal, which can bind famotidine in the gut and sharply cut how much of the drug reaches your blood.”

About Adrenal Extract

What is Adrenal Extract?

  • Fatigue and low energy
  • "Adrenal fatigue" support
  • Stress and burnout
  • Low energy after illness
  • General "adrenal support"

Adrenal extract is a glandular supplement made from the adrenal glands of animals, and it is marketed mainly for fatigue and so-called "adrenal fatigue." There is no good scientific evidence that it works, and "adrenal fatigue" is not a recognized medical diagnosis. Because of possible safety and contamination concerns, talk with your pharmacist or doctor before trying it.

Adrenal glands (cortex and/or whole gland) of cattle, pigs, or sheep · Capsules, tablets, and glandular powder extracts

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

Adrenal Extract: dosing

There is no established or standardized dose for adrenal extract. Products vary widely in their source, strength, and ingredients, so there is no reliable "correct" amount.If you choose to use it despite the limited evidence, follow the directions on the product label and do not take more than recommended. Choosing brands that use independent third-party testing may help with quality, but it does not guarantee that the product works.

About Famotidine

What Is Famotidine Used For?

Brand names: Pepcid, Famotidine, Pepcid AC, Famotidine Injection

Famotidine treats a range of acid-related conditions. Over-the-counter tablet products — including Acid Controller, Acid Reducer, Acid Relief, Amazon Basic Care Acid Reducer, basic care acid reducer, and Calmicid AC — are used to relieve and prevent heartburn associated with acid indigestion and sour stomach.

Prescription-strength famotidine tablets and oral suspension are indicated for active duodenal ulcers (ulcers in the small intestine), active gastric ulcers (stomach ulcers), GERD (acid reflux disease), erosive esophagitis (acid-damaged esophagus), and pathological hypersecretory conditions such as Zollinger-Ellison syndrome. The oral suspension is also indicated in children from birth onward for GERD and, in children one year and older, for peptic ulcer disease. Famotidine injection is used in hospitalized patients who cannot take medication by mouth.
