Sourced concerns (2)
ConsensusEndocrineconfidence 100%
Oral administration of famotidine does not significantly affect pituitary, sexual, or thyroid hormone levels.
- Why here
- Studies directly investigated the impact of ingested famotidine on various hormone levels in humans.
- What would have to be true
- Ingestion of therapeutic doses (e.g., 20-40 mg daily) for short-term (4 weeks) or long-term (6 months) periods.
Sources the engine cites:
ConsensusMetabolicconfidence 100%
Famotidine is primarily eliminated through the kidneys, and dosage adjustments are necessary for individuals with moderate to severe renal impairment to prevent increased drug levels and potential toxicity.
- Why here
- Ingested famotidine is metabolized and excreted, with renal function being a critical factor in its clearance from the body.
- What would have to be true
- Ingestion of therapeutic doses of famotidine by individuals with compromised renal function (e.g., creatinine clearance less than 30 mL/min).

In its favour (1)
ConsensusClearedconfidence 100%
Famotidine has shown no evidence of carcinogenic potential in animal studies and has not been associated with cancer development in humans.
- Why here
- Carcinogenicity studies were conducted via oral administration, directly assessing the risk for ingestion.
- What would have to be true
- Ingestion of therapeutic doses of famotidine.
- The other side
- While some other acid-reducing medications (Proton Pump Inhibitors) have been linked to increased cancer risk with long-term use, famotidine (an H2 blocker) is considered a safer alternative in this regard.

Not researched here
The engine has no dossier for famotidine when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.
This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.
Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
