Dehydration and subsequent prerenal acute kidney injury can result when temperatures begin to rise in the summer months.  As a result, medications with narrow therapeutic indices that are primarily renally excreted may accumulate.  Here are the specific ones to look out for:

  • Digoxin
  • Lithium
  • Colchicine
  • Phenobarbital and theophylline (partially eliminated unchanged by the kidneys)
