What is Primacor?
Primacor is a vasodilator that works by relaxing the muscles in your blood vessels to help them dilate (widen). This lowers blood pressure and allows blood to flow more easily through your veins and arteries.
Primacor is used as a short-term treatment for life-threatening heart failure.
Primacor may also be used for purposes not listed in this medication guide.
In an emergency situation it may not be possible to tell your caregivers about your health conditions. Make sure any doctor caring for you afterward knows you have received this medicine.
