Measure
Prazosin
1. Prazosin 1mg given to observe if medication is tolerated or if signs or symptoms of hypotension develop (e.g. dizziness, lightheadedness). 2. If the patient remains asymptomatic and BP \>110/60 mmHg, prazosin is continued at 1mg every 8 hours (q8h). 3. Day 3: If the patient remains asymptomatic and BP \>110/60 mmHg, increase dose to 2mg q8h. 4. Day 6: If the patient remains asymptomatic and BP \>110/60 mmHg, increase dose to 5mg q8h. 5. If the BP is \<100/60 mmHg at any time, the next dose should be held, and patient continues with the highest previously tolerated dose 8 hours later. 6. If the patient did not tolerate dose escalation to 5mg q8h, one attempt is made to increase dose to 3mg q8h. If this is not tolerated, the patient continues with the highest previously tolerated dose 8 hours later. If BP monitoring is not available, repeated occurrences of postural dizziness should trigger drug dose reduction or BP monitoring. Prazosin: Participants in this arm will receive the study drug as outlined in the arm description.
