... mid 80's, whose Bp is generally 155 over 75 but can spike to 183 over 75 under stress,Thanks
Hello juniper1 & welcome to the site. I am not a doctor, but the literature on Diovan states that doses of higher than 160mg in elderly can precipatate falls, so that may be the reason that her doctor at her age is keeping at the 160 dose See below.
Dose-related orthostatic effects were seen in less than 1% of patients. An increase in the incidence of dizziness was observed in patients treated with Diovan 320 mg (8%) compared to 10 to 160 mg (2% to 4%).
You did not say whether she is also on a diuretic or any other type of blood pressure med. See below
The recommended starting dose of Diovan is 80 mg once daily when used as monotherapy in patients who are not volume-depleted. Diovan may be used over a dose range of 80 mg to 320 mg daily, administered once-a-day.
The antihypertensive effect is substantially present within 2 weeks and maximal reduction is generally attained after 4 weeks. If additional antihypertensive effect is required, the dosage may be increased to 160 mg or 320 mg or a diuretic may be added. Addition of a diuretic has a greater effect than dose increases beyond 80 mg.
No initial dosage adjustment is required for elderly patients, for patients with mild or moderate renal impairment, or for patients with mild or moderate liver insufficiency. Care should be exercised with dosing of Diovan in patients with hepatic or severe renal impairment.
