Consider dosing on an mg/kg basis. Improvements were observed starting at doses of 0.05-0.08 mg/kg once daily. Doses up to 0.12 mg/kg once daily may provide additional benefits (2.2). When discontinuing, taper the dose in decrements of no more than 1 mg every 3 to 7 days. Which dr...
In a limited number of patients with renal impairment, concomitant administration of guanfacine with a known microsomal enzyme inducer (phenobarbital or phenytoin) resulted in decreased elimination half-life and plasma concentrations of guanfacine. More frequent dosing of guanfacine may be required in ...
Consider dosing on a mg/kg basis. Improvements have been observed starting at dosages of 0.05 to 0.08 mg/kg once daily. Dosages up to 0.12 mg/kg once daily may provide additional benefit. Dosages above 4 mg/day haven't been studied. If switching from immediate-release guanfacine, ...
Guanfacine lowered lying and standing plasma norepinephrine; this continued on long-term dosing. Urinary catecholamines were reduced from 59.21 +/- 17.24 (mean +/- SEM) to 28.91 +/- 4.20 micrograms/24 hr after 7 days of treatment. The hemodynamic effects, side effects, and biochemical evidence...

Dosing And Administration Instruct patients to swallow INTUNIV® whole with water, milk or other liquid. Tablets should not be crushed, chewed or broken prior to administration because this may increase the rate of release of the active drug. Patients should not take INTUNIV® together with a...
the therapeutic applications for guanfacine are similar to those of the other centrally acting α2-adrenergic agonists and methyldopa. It has been effective as monotherapy in the treatment of patients with mild to moderate hypertension. One advantage for guanfacine is its once-a-day dosing schedule....
The administration of guanfacine concomitantly with a known microsomal enzyme inducer (phenobarbital or phenytoin) to two patients with renal impairment reportedly resulted in significant reductions in elimination half-life and plasma concentration. In such cases, therefore, more frequent dosing may be requ...
