Famotidine is an over-the-counter histamine H2 receptor antagonist, sold under the trade name Pepcid, that has been identified as a potent serotonin antagonist capable of stopping acute serotonin syndrome, a condition with a lethality rate over 40%. Georgi Dinkov has emphasized that at a dosage of just 20 milligrams, a single pill can produce a profound anti-serotonin effect, and studies have demonstrated it can rapidly drop blood sugar in type 2 diabetics from a range of 180–200 mg/dL to below 100 mg/dL, an effect attributed to its interruption of serotonin's drive on cortisol. Unlike the newer proton pump inhibitors (PPIs) such as Prilosec and Nexium, which Dinkov describes as highly toxic and capable of inducing atrophic gastritis—a precursor to gastric cancer—famotidine is an older drug that actually has a trophic effect on the gastric mucosa, making it therapeutic for healing gastritis rather than merely suppressing acid.
Dinkov has written that famotidine's anti-serotonin action extends to resolving symptoms of intestinal irritation that manifest as systemic allergies, and he notes that people with asthma and severe allergies see these symptoms disappear when taking it, even though it is not classified as an H1 antagonist. He has also reported that a single 20 mg dose can stop the wave of endotoxin symptoms—low-grade fever, chills, and shivering—permanently, sometimes more reliably than cyproheptadine. The drug's mechanism is further broadened by its action as a carbonic anhydrase inhibitor, which Dinkov states is even more powerful than vitamin B1 or acetazolamide, and likely explains its observed benefit in COVID-19 by alleviating carbon dioxide deficiency and hypoxia. This inhibition of carbonic anhydrase positions famotidine as a tool for improving cellular respiration and CO2 retention.
In the context of digestive health, Dinkov contrasts famotidine sharply with PPIs, which he argues decimate stomach acid production and allow bacterial colonization of the small intestine, causing hard-to-eradicate intestinal overgrowth and endotoxemia. Famotidine, by acting as an antihistamine and anti-serotonin agent, handles acid-related issues without abolishing acid production entirely, making it one of the best interventions for digestion. It is also recommended as an accessible anti-serotonin remedy for food poisoning, where it helps with nausea and the underlying effects, and can be combined with charcoal or coconut oil to increase gastric motility and cleanse the tract. Dinkov has noted that its only known side effect, inhibition of platelet aggregation, is consistent with its anti-serotonin profile and is shared by aspirin and cyproheptadine.
