One relatively unknown use of DDAVP (Desmopressin)
Desmopressin (DDAVP) can be use in treatment of sleep apnea. Patients prescribed DDAVP are found to have 4.5 times more likely to sleep without disruption than with placebo. FDA has banned the treatment of sleep apnea with desmopressin, particularly nasal sprays due to reported deaths, hyponatremia and seizures.
Desmopressin tablets are still use for sleep apnea. Side effects are as above along with severe vomiting, diarrhea, fever and flu like symptoms.
