The usual starting and maintenance dose of levatol®, used alone or in combination with other antihypertensive agents, such as thiazide-type diuretics, is 20 mg given once daily.
Doses of 40 mg and 80 mg have been well-tolerated but have not been shown to give a greater antihypertensive effect. The full effect of a 20- or 40-mg dose is seen by the end of 2 weeks. A dose of 10 mg also lowers blood pressure, but the full effect is not seen for 4 to 6 weeks.
