LessWrong Blog: Immunotherapy Can Eliminate Seasonal Allergies for ~$1,000

Rattengift's recent LessWrong post, 'You can opt out of allergies,' argues that immunotherapy offers a permanent escape from seasonal allergy misery. Two primary methods exist: subcutaneous immunotherapy (SCIT), involving regular injections over several months, and sublingual immunotherapy (SLIT), using daily drops or tablets held under the tongue. SCIT is widely covered by US insurance, while SLIT (especially drops) often requires out-of-pocket payment—Amazon's primary care service offers drops, though costs are unclear. The post cites research showing SLIT's long-standing success in Europe and references studies (PMC10788274, Ajcn.nutrition.org, Jacionline.org) demonstrating effectiveness for both environmental and food allergies, including peanut allergies. Importantly, self-administering food allergy immunotherapy is strongly discouraged due to severe reaction risks.

For thought-intensive professionals, the productivity gains from reduced brain fog and physical discomfort easily justify the cost—equivalent to 'a new laptop or synthesizer.' Comments add real-world experiences: user Austin Chen shares his 3-month SLIT journey, noting sweet-tasting drops but a 2-minute daily holding requirement, and estimates 6–12 months for full effect. Another commenter warns that SCIT requires frequent doctor visits (once or twice weekly during ramp-up), but Rattengift counters that even a lengthy commute pays off cognitively. While not AI-related, the post highlights a pragmatic, evidence-based health hack gaining traction in rationalist communities.
