Pregnancy Prolonged experience with desmopressin in pregnant women over several decades, based on available published data and case reports, did not identify a drug associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes; in addition, in vitro studies with human placenta demonstrate poor placental transfer of desmopressin; no adverse developmental outcomes were observed in animal reproduction studies with administration of desmopressin during organogenesis to pregnant rats and rabbits at doses approximately <1 and 38 times, respectively, the maximum recommended human dose based on body surface area (mg/m²) Not recommended for treatment of nocturia in pregnant women; nocturia is usually related to normal, physiologic changes during pregnancy that do not require treatment Lactation Desmopressin is present in small amounts in human milk and is poorly absorbed orally by infant There is no information on effects of desmopressin on breastfed infant or on milk production; development and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and potential adverse effects on breastfed infant from therapy or from the underlying maternal condition

May enhance antidiuretic effect w/ NSAIDs (e.g. ibuprofen), indometacin, TCAs, chlorpromazine, carbamazepine, SSRIs, opiates, lamotrigine. May reduce antidiuretic effect w/ lithium, epinephrine (large dose), heparin, demeclocycline.

Desmopressin increases cyclic adenosine monophosphate (cAMP) in renal tubular cells which increases water permeability resulting in reduced urine volume and enhanced urine osmolality. It also stimulates factor VII and plasminogen activator activity in the blood, but w/ minimal pressor activity. Onset: Antidiuretic: Approx 60 min (oral); 15-30 min (intranasal).
