Children may be especially sensitive to the effects of dental anesthetics. This may increase the chance of unwanted effects, some of which can be serious, during treatment. When using a dental anesthetic for a child, be very careful not to use more of the medicine than directed on the label, unless otherwise directed by your health care professional. Teething medicines that contain benzocaine may be used in babies 4 months of age and older. One product that contains benzocaine (Orabase-B with Benzocaine) may be used in children 6 years of age and older. Most of the other nonprescription (over-the-counter [OTC]) medicines that contain a dental anesthetic may be used in children 2 years of age and older. However, these other nonprescription products should not be used in infants or children younger than 2 years of age unless prescribed by a health care professional.
Elderly people are especially sensitive to the effects of many local anesthetics. This may increase the chance of side effects during treatment, especially with lidocaine. Nonprescription (over-the-counter [OTC]) products containing local anesthetics are not likely to cause problems. However, elderly people should be especially careful not to use more medicine than directed on the package label, unless otherwise directed by a medical doctor or a dentist.
Dental anesthetics have not been reported to cause birth defects or other problems in humans.
Dental anesthetics have not been reported to cause problems in nursing babies.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
