Recommended treatment for confirmed RH includes optimization of lifestyle interventions, use of a long-acting thiazide-like diuretic (e.g., chlorthalidone, FDA CONTINUES TO FIGHT OPIOID CRISIS indapamide), and addition of a mineralocorticoid receptor In an effort to combat the US opioid crisis, the antagonist (e.g., spironolactone, eplerenone).
