Dosing from Propranolol Treatment of Chronically Hospitalized Aggressive Patients, Jonathan M. Silver MD, et al, J Neuropsychiatry Clin Neurosci 11:3, Summer 1999:
Essentially, they dosed propranolol as high as tolerated, always taking vitals prior to dose. They started 20mg qid x4 days, then 40mg qid, continuing to increase 20mg qid every other day until 100mg qid reached, then increased by 20mg qid daily until 360mg qid (total 1440mg daily !! - well above the usual HTN max of 640mg daily) or 20mg/kg, whichever was higher!! Vitals were taken before each dosage. If the patient had c/o dizziness, ataxia or wheezing, or HR < 50 or systolic BP <90, propranolol was not increased and maintained at a dosage that was better tolerated.
