The usual initial dosage is 2.5 mg, 2-3 times daily (every 3-4 hours). The dose should be increased at weekly intervals in small increments until an optimal response is obtained (max 30 mg/day) and taken during daytime when the person performs daily activities in upright position. The last dose should be taken at least four hours before bedtime to reduce the risk of supine hypertension. Blood pressure in supine and sitting position should be regularly monitored at the beginning of the treatment (at least twice a week). Treatment should be stopped if supine hypertension is significantly excessive.
