Official title

Disulfiram ("Antabuse"): A Test of Symptom Reduction Among Patients With Previously Treated Lyme Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Approximately 10-20% of patients experience ongoing symptoms despite having received standard antibiotic therapy for Lyme disease. Possible explanations for persistent symptoms include persistent infection and/or post-infectious causes. Recent in vitro studies indicate that disulfiram is effective at killing both the actively replicating and the more quiescent persister forms of Borrelia burgdorferi, the microbe that causes Lyme Disease. In this study, the investigators are examining the safety of disulfiram among patients with post-treatment Lyme disease symptoms. The investigators are also conducting a preliminary investigation regarding the relative benefit of 4 vs 8 weeks of treatment with disulfiram.
