A case of methamphetamine use disorder treated with the antibiotic drug minocycline.

Methamphetamine (METH) use is one of the major public health concerns worldwide. Long-term use of METH induces not only dependence but also psychosis which is associated with METH-induced brain damage, including neuroinflammation produced by activated microglia. We report the case of a female patient whose psychotic symptoms in METH use disorder were successfully improved by anti-inflammatory drug minocycline therapy. Although the precise mechanism(s) underlying the efficacy of minocycline in METH use disorder are currently unclear, minocycline appears to be a good candidate for future investigation clinical trials for medication development in METH using populations.
