What is Marcaine HCl?

Marcaine HCl is an anesthetic (numbing medicine) that blocks nerve impulses in your body.

Marcaine HCl is used as a local (in only one area) anesthetic.

Marcaine HCl is given as an epidural injection into the spinal column to produce numbness during labor, surgery, or certain medical procedures.

Marcaine HCl is also used as an anesthetic for dental procedures.

Marcaine HCl may also be used for purposes not listed in this medication guide.

Important Information

Tell your doctor if you have ever had an allergic reaction to any type of numbing medicine.

Some epidural numbing medications can have long-lasting or permanent effects on certain body processes such as sexual function, bowel or bladder control, and movement or feeling in your legs or feet. Talk with your doctor about your specific risk of nerve damage from Marcaine HCl.

Before taking this medicine

Tell your doctor if you have ever had an allergic reaction to any type of numbing medicine, or if you've ever had:

  • anemia (lack of red blood cells);

  • kidney or liver disease;

  • a bleeding or blood clotting disorder;

  • syphilis, polio, a brain or spinal cord tumor;

  • numbness or tingling;

  • chronic back pain, headache caused by surgery;

  • low or high blood pressure;

  • abnormal curvature of the spine; or

  • arthritis.

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

Tell your doctor if you are breast-feeding.

How is Marcaine HCl given?

Marcaine HCl is injected through a needle directly into or near the area to be numbed. You will receive this injection in a dental or hospital setting.

For an epidural, Marcaine HCl is given as an injection through a needle placed into an area of your middle or lower back near your spine.

For a dental procedure, Marcaine HCl is injected directly into the mouth near the tooth or teeth your dentist will be working on.

Your breathing, blood pressure, oxygen levels, or other vital signs will be watched closely.

Some epidural numbing medications can have long-lasting or permanent effects on certain body processes such as sexual function, bowel or bladder control, and movement or feeling in your legs or feet. Talk with your doctor about your specific risk of nerve damage from Marcaine HCl.

What happens if I miss a dose?

Since Marcaine HCl is given as needed before a surgery or dental procedure, you are not likely to be on a dosing schedule.

What happens if I overdose?

Since Marcaine HCl is given in a medical setting, you will be watched closely to make sure you do not receive too much of Marcaine HCl. Your caregivers will quickly treat you if you have overdose symptoms.

What should I avoid after receiving Marcaine HCl?

This medicine can cause numbness over a large portion of your body. Take care to avoid injury before the feeling has returned completely.

After a dental procedure, avoid eating, chewing gum, or drinking a hot beverage until your mouth is no longer numb.
