Question explored with the scientific record
What are the best methods for treating chronic Lyme?
The short version: no single "best" treatment for chronic Lyme exists because the condition itself is poorly defined and the evidence for any approach is thin.
The retrieved studies do not directly test treatments for chronic Lyme disease. They mostly test short-term antibiotics for early Lyme or for other infections entirely. One 2008 trial of repeated IV ceftriaxone for "Lyme encephalopathy" found short-term cognitive gains that did not last after treatment stopped [1]. A 2013 study gave ceftriaxone or placebo to patients with persistent cognitive deficits and found no consistent changes in immune markers or symptoms [3]. These are the closest the retrieval gets, and they do not support prolonged antibiotics.
The evidence that does exist focuses on the complexity of the problem. A 2018 review of 200 chronic Lyme patients found that 72.5% had immune dysfunction, 84.5% had elevated heavy metals, and 98% had sleep disorders [4]. The same study reported that a "persister-targeting" approach improved major symptoms in 82% of patients, but this was an uncontrolled chart review, not a randomized trial [4]. A 2015 study estimated that persisting symptoms after Lyme disease cause about 1.7 disability-adjusted life years per patient, a substantial burden [2].
What this means for you: the standard approach (2-4 weeks of doxycycline or ceftriaxone) was designed for acute infection, not for the chronic, multifactorial illness many patients describe. The evidence for longer or repeated antibiotics is weak. The evidence for addressing the broader picture - immune support, detoxification, sleep, gut health - is suggestive but comes from uncontrolled studies. No trial has compared a comprehensive protocol to a true placebo in a blinded, randomized way.
My call: the evidence does not support any single "best" treatment for chronic Lyme. The most promising approach, based on the limited data, addresses the full range of underlying factors rather than just the infection. But this is a hypothesis, not a proven method. Confidence: low.
