Doxazosin is indicated for the treatment of urinary outflow obstruction and symptoms associated with benign prostatic hyperplasia (BPH). Doxazosin may be used in BPH patients who are either hypertensive or normotensive.
For this indication, competent medicine agencies globally authorize below treatments:
For: Adults (18-64) Elders (65+)
Oral, 1 milligrams, once daily, over the duration of 2 weeks. Afterwards, oral, between 2 and 4 milligrams, once daily. The maximum allowed total dose is 8 milligrams daily.
The recommended initial dosage of doxazosin is 1mg given once daily to minimise the potential for postural hypotension and/or syncope. Depending on the individual patient’s urodynamics and BPH symptomatology dosage may then be increased to 2mg and thereafter to 4mg and up to the maximum recommended dose of 8mg. The recommended titration interval is 1-2 weeks. The usual recommended dose is 2-4mg daily.
