Respiratory infections during lithium and valproate medication: a within-individual prospective study of 50,000 patients with bipolar disorder.

ABSTRACT:

Background

In vitro studies have demonstrated that lithium has antiviral properties, but evidence from human studies is scarce. Lithium is used as a mood stabilizer to treat patients with bipolar disorder. Here, the aim was to investigate the association between lithium use and the risk of respiratory infections in patients with bipolar disorder.

Method
