Xylocaine-MPF is sometimes used to treat irregular heart rhythms that may signal a possible heart attack.

Xylocaine-MPF is also given in an epidural (spinal block) to reduce the discomfort of contractions during labor.

How is Xylocaine-MPF given?

A healthcare provider will give you this injection.

When used to treat heart rhythm problems, lidocaine is given as an infusion into a vein.

When used as a local anesthetic, lidocaine is injected through the skin directly into the body area to be numbed.

Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely while you are receiving Xylocaine-MPF in a hospital setting.

If you are being treated for irregular heart rhythm, your heart rate will be constantly monitored using an electrocardiograph or ECG (sometimes called an EKG). This will help your doctor determine how long to treat you with Xylocaine-MPF.
