For people not taking a diuretic drug, the usual starting dose is 7.5 milligrams taken once a day, an hour before a meal.
The maximum dose is 60 milligrams per day.
The dosage after that can range from 7.5 to 30 milligrams per day, taken in either a single dose or divided into 2 equal doses daily.
Your doctor will closely monitor the effect of this drug and adjust it according to your individual needs.

This reduces the possibility of fainting or light-headedness.
People already taking a diuretic should stop taking it, if possible, 2 to 3 days before starting Univasc.
If Univasc alone does not control your blood pressure, your doctor will have you start taking a diuretic again.
If the diuretic cannot be discontinued, the starting dosage of Univasc should be 3.75 milligrams.

For people with kidney problems, the usual starting dose is 3.75 milligrams a day your doctor may gradually raise the dose to a maximum of 15 milligrams a day.


Although there is no specific information available, a sudden drop in blood pressure would be the most likely symptom of Univasc overdose.
