On this episode, I discuss prazosin pharmacology, adverse effects, drug interactions and much more.



Prazosin is an alpha-blocker but lacks selectivity. A reduction in blood pressure is expected, but it is notorious for causing orthostatic hypotension.



Prazosin may be used off-label for nightmares, when this is the case, you will likely only see this drug dosed at bedtime.



Alpha agonist medications (such as pseudoephedrine and ADHD stimulants) may counteract the effects of prazosin.
