Lithium Long COVID Dose-finding Study

Effect of Low-dose Lithium Therapy on Long COVID Symptoms: an Open-label, Dose-finding Study.

This open-label study will assess if lithium dosages of 30-45mg/day are associated with greater symptomatic benefit than dosages of 10-15mg/day previously assessed among 50 patients with long COVID.
