What is the most important information I should know about Univasc?

Return to top

Blood pressure medications known as angiotensin converting enzyme (ACE) inhibitors, such as Univasc, have been shown to cause injury and even death of the developing baby when used during the second and third trimesters of pregnancy. When pregnancy is confirmed, call your doctor right away Univasc.

Univasc can cause a severe drop in blood pressure if you lose too much liquid through excessive sweating, severe diarrhea, or vomiting. Contact your doctor immediately if you develop one of these problems.

You must take Univasc regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Univasc, and you must continue taking it even if you are feeling well. Univasc does not cure high blood pressure; it merely keeps it under control.

If you develop swelling of your face, around the lips, tongue, or throat; swelling of your arms and legs; sore throat; or difficulty breathing or swallowing, stop taking the drug and contact your doctor immediately. You may need emergency treatment.

What is the usual dosage?

The information below is based on the dosage guidelines your doctor uses. Depending on your condition and medical history, your doctor may prescribe a different regimen. Do not change the dosage or stop taking your medication without your doctor's approval.

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

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

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

Children: The safety and effectiveness of Univasc have not been established in children.
