What is lidocaine viscous?

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

Lidocaine viscous is used to treat sores inside the mouth, during dental procedures to numb the gums, and to numb the mouth and throat before a surgery or medical procedure.

Lidocaine viscous may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before using lidocaine viscous?

An overdose of numbing medication can cause fatal side effects if too much of the medicine is absorbed through your gums and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor. Overdose symptoms may include drowsiness, slow heartbeats, seizure (convulsions), slowed breathing, or breathing that stops.

Do not use lidocaine viscous to treat teething pain in a baby. A baby could accidentally swallow this medicine if it is placed in the mouth. Heart problems, seizures, severe brain injury, and death can occur from the use of this medicine in very young children. Always ask a doctor before using any medicine to treat your baby's teething pain.

You should not use lidocaine viscous if you are allergic to any type of numbing medicine.

To make sure lidocaine viscous is safe for you, tell your doctor if you have:

  • liver disease;
  • a serious heart condition such as "AV block";
  • an allergy to any drugs; or
  • broken, swollen, or damaged skin or gum tissue.

Lidocaine viscous is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.

If your medicine comes with patient instructions for safe and effective use, follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Lidocaine viscous may be applied with your finger tips or a cotton swab, or with the applicator provided with the medicine.

Use the smallest amount of this medication needed to numb or relieve pain. Do not use large amounts of lidocaine viscous.

Avoid swallowing the medicine while applying it to your gums or the inside of your mouth.

Your body may absorb more of this medicine if:

  • you use too much;

  • you apply the medicine to gum tissue that is cut or irritated; or
  • you apply heat to a treated area.

Avoid eating within 1 hour after using this medicine inside your mouth or throat. You may have trouble swallowing and choking could occur, especially in a child.

Store at room temperature away from moisture and heat.

What happens if I miss a dose?

Since lidocaine viscous is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What should I avoid while using lidocaine viscous?

Avoid eating, chewing gum, or drinking hot liquids until the feeling in your mouth has returned completely. Chewing while your mouth is numb could result in a bite injury to your tongue, lips, or inside of your cheek.

Do not allow the medicine to come into contact with your eyes. Rinse with water if this medicine gets in your eyes.

Avoid using other medications on the areas you treat with lidocaine viscous unless your doctor tells you to.
