==== History ====
* '''Nocturia be a symptom of serious systemic illnesses including hypertension, diabetes, heart disease, and kidney disease'''
* '''<span style="color:#ff0000">Drug effects causing nocturia</span>'''

**# '''SSRIs''' (block antidiuretic hormone secretion)
**# '''Tetracycline''' (attenuates antidiuretic hormone via decreases in cAMP accumulation and action)
**# '''Calcium channel blockers''' (increases atrial natriuretic peptide, blocks sodium reabsorption in proximal convoluted tubule)
**# '''Lithium (drug-induced nephrogenic diabetes insipidus)'''
**# '''Diuretics: timing of diuretic administration should be mid-afternoon''', to allow for elimination of lower extremity excess body fluid during normal waking hours. Men with nocturnal polyuria may benefit from diuretic therapy 6 hours before sleep
