Date: December 30, 2025
Featuring: "Drug Story" episode, hosted by Thomas Goetz
Main Guests: Dr. Gideon Lack, Alexander Hadji, Lauren Gilmer

Episode Overview

This episode features an installment of the new podcast "Drug Story" by Thomas Goetz, focusing on the medical, historical, and economic saga of the EpiPen and the meteoric rise of food allergies in recent decades. Through personal anecdotes, expert interviews, and a thorough investigation of scientific breakthroughs and regulatory failures, the episode explores how well-intentioned medical advice contributed to the epidemic and what we’ve learned since.

Key Points & Insights

1. Personal Stories: Living with Food Allergies

• Alexander Hadji (00:53–06:43) shares a detailed account of living with multiple severe food allergies, including a recent anaphylactic episode involving tuna and the life-saving use of an EpiPen.
  • "I've never eaten a single food from any restaurant ever in my life. I always bring my own food." (03:38 – Alexander)
  • "I want to say you inject yourself in the thigh with the needle, but it's more like you really want to, like, smack yourself with it sometimes." (05:57 – Alexander on using the EpiPen)
• Lauren Gilmer recalls a childhood anaphylactic reaction and how the EpiPen saved her:
  • "I was having a really hard time breathing, and I felt this panic rising up in me." (37:40 – Lauren)

2. Diagnosis: The Discovery & Understanding of Anaphylaxis

• Historical account of the first identification of anaphylaxis by French scientists Richet and Poitier in 1901 during experiments on the Portuguese Man o’ War. Rather than causing immunity, their experiment made animals more sensitive.
  • "It was then that we noticed with surprise that the results were not those we expected... Certain ones seemed sensitized." (13:28 – Poitier via actor)
  • Richet receives Nobel Prize in 1913, describes "elementary anaphylaxis":
    "What is food for some may be fierce poison for others." (16:02 – referencing Lucretius)
• Allergic reactions historically rare; even in the 1960s, food allergy was a medical curiosity.
• Mechanism: For some, immune systems misidentify proteins as poisons, causing anaphylaxis.

3. The Great Blunder: How Caution Became Catastrophe

• Dr. Gideon Lack explains immune tolerance is developed by early exposure to foods.
  • "During embryological development... the immune system doesn't attack itself... The same has to happen after birth to foods." (18:53 – Dr. Lack)
• The 1-2-3 Rule: In 2000, the American Academy of Pediatrics recommends late introduction to allergenic foods—dairy after age 1, eggs after age 2, peanuts/seafood after age 3. This advice was based on the precautionary principle, not science.
• Avoidance created a feedback loop—delayed exposure led to increased food allergy sensitization.

4. The Israeli "Bamba" Clue & Gideon Lack’s Research

• Dr. Lack observes much lower rates of peanut allergies in Israeli children routinely fed "Bamba" (a peanut snack) early in life, versus UK Jews.
  • "We got our responses... the rate of peanut allergy in the UK Jewish children was about 2%, which was about tenfold higher than in the Israeli school children." (27:22 – Dr. Lack)
• Observational studies suggest early exposure lowers allergy risk, but guidelines did not change.

5. Business & Controversy: EpiPen’s Rise and Cost Explosion

• EpiPen, invented as a military device, became an allergy treatment in 1987.
• Acquired by Mylan in 2007, the EpiPen's price soared from $109 to over $600 a two-pack by 2016, driven by:
  • Short expiration (~1 year), regulatory/lobbying moves (schools mandated to stock EpiPens), bundling (double packs), and lack of direct competitors due to training lock-in.
• Congressional hearings in 2016 highlighted the outrage over pricing.
  • "Why did you lower it by half if you thought it was fair?... Well, if it cost 20 bucks, they could afford to buy their own." (44:08–45:09 – Congressional questioning of Mylan CEO)

6. The Scientific Reversal: LEAP Study and New Guidelines

• Dr. Lack conducts the LEAP Study: Randomizes infants (4-11 months old) to early peanut exposure or avoidance.
  • At age five, 14% of avoiders had peanut allergies vs. just 1.9% of early-exposure kids.
  • "I was really astonished that it would be that high... That's at a level of very successful vaccines in terms of protection." (49:13 – Dr. Lack)
• 2017: NIH/NIAID reverses course—now recommends early introduction of allergens.
  • Dr. Fauci: "You tolerize the child to not make a bad response against the peanuts." (50:07 – Fauci)
• Dr. Lack: "Undoing that way of thinking is very difficult." (51:13)

7. Aftermath & Continuing Challenges

• Despite new guidelines, allergy rates continue rising—due to persistent caution ("better safe than sorry") and hygiene practices.
  • "Despite the change in guidance, food allergies are not going down. Even after the guidance shifted in 2017, rates... have continued to increase." (51:56)
• EpiPen revenue has doubled again ($2 billion in 2023); the cost now ~$700 for a two-pack.
  • "Drug pricing is a very confusing, very convoluted subject, and it's one we will return to again in other episodes." (52:53)
• Some hope from new therapies: Allergen immunotherapy (exposure therapy) and new drugs like Palforzia now offer options for treating allergies, not just preventing them.

Notable Quotes & Memorable Moments

• Alexander Hadji on Allergic Vigilance:
  "I've never eaten a single food from any restaurant ever in my life. I always bring my own food." (03:38)

• On Medical Error:
  “What the AAP had done was to unintentionally create a feedback loop… this was exactly the wrong advice.” (23:34)

• On Scientific Humility:
  "We don't hold all the answers, and very often we get it wrong before we get it right. And I got it wrong... People change their minds. I think it's important to change one's mind when new evidence comes about." (51:36 – Dr. Lack)

• On Economic Reality:
  "If it cost 20 bucks, they could afford to buy their own. You wouldn't have to give them to them. But instead, you chose to jack the prices up...” (45:09 – Congressman)

• On Reversal of Allergies:
  "Maybe low level, regular supervised exposure in an allergic child might be a better thing than avoidance... you don’t reverse or cure the disease, but you get these children to be able to tolerate significant amounts." (54:54 – Dr. Lack)

Tone & Style

Thomas Goetz weaves together clinical stories, history, and policy with accessible explanations, an investigative drive, and frequent use of suspense and irony. The episode’s tone is conversational but information-rich, blending narrative storytelling with clear scientific exposition.

Takeaways

• The EpiPen’s journey from military device to household necessity is a tale of innovation, medical error, industry opportunism, and eventual policy correction.
• Well-intentioned public health guidance triggered an explosion in food allergies—an error recognized and reversed only after rigorous science (LEAP trial).
• Despite new evidence, social inertia and systemic factors keep allergy rates and EpiPen prices high, showing the complexity of changing hearts, minds, and markets.
• Voices like Dr. Gideon Lack’s advocate humility in medicine and the importance of changing course as new evidence emerges.
• Therapies are improving, but vigilance and policy reform are still needed for sustainable progress.
