What is UAD Caine?

Lidocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.

UAD Caine is used to numb an area of your body to help reduce pain or discomfort caused by invasive medical procedures such as surgery, needle punctures, or insertion of a catheter or breathing tube.

UAD Caine is sometimes used to treat irregular heart rhythms that may signal a possible heart attack.

UAD Caine is also given in an epidural (spinal block) to reduce the discomfort of contractions during labor.

UAD Caine may also be used for purposes not listed in this medication guide.

Important Information

You should not receive UAD Caine if you have severe heart block, or a heart rhythm disorder called Stokes-Adams syndrome or Wolff-Parkinson-White Syndrome.

Before taking this medicine

You should not receive this medicine if you are allergic to UAD Caine or any other type of numbing medicine, or if you have:

  • severe heart block;

  • a heart rhythm disorder called Stokes-Adams syndrome (sudden slow heart beats that can cause you to faint); or

  • a heart rhythm disorder called Wolff-Parkinson-White Syndrome (sudden fast heartbeats that can cause you to faint or become easily tired).

Tell your doctor if you have ever had:

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant.

It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.

How is UAD Caine 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 UAD Caine 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 UAD Caine.

What happens if I miss a dose?

Since UAD Caine is used only when needed in a clinical setting, you are not likely to miss a dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid after receiving UAD Caine?

UAD Caine can cause side effects that may impair your thinking or reactions. Unless absolutely necessary, do not drive after receiving UAD Caine.

Avoid eating or chewing within 1 hour after UAD Caine is used to numb your mouth or throat. You may have trouble swallowing which could lead to choking. You may also accidentally bite the inside of your mouth if you are still numb an hour after treatment with this medicine.
