How to Use lidocaine
This medicine is for use on the skin. This medicine may be used in the mouth, nose, or throat and may be applied by a health care professional. Follow the directions on the prescription label. Apply your medicine at regular intervals. Do not use it more often than directed.
Talk to your pediatrician regarding the use of this medicine in children. While this drug may be prescribed for selected conditions, precautions do apply.
They need to know if you have any of these conditions:
- heart problems

If you miss a dose, use it as soon as you can. If it is almost time for your next dose, use only that dose. Do not use double or extra doses.
Be careful to avoid injury while the area is numb and you are not aware of pain. If this medicine is used in the mouth or throat, do not chew gum or eat food for at least one hour. If the area is still numb, you may choke or bite your tongue or cheek if you try to chew or swallow. Also, you may not feel pain from hot foods or drinks.
Do not apply this medicine to areas of skin that are infected, open or damaged. This may increase the amount of medicine that passes through your skin and increase the risk of serious side effects.
