Cocaine (Topical Route)
Original Article: http://www.mayoclinic.com/health/drug-information/DR600467
Cocaine is a local anesthetic. It is applied to certain areas of the body (for example, the nose, mouth, or throat) to cause loss of feeling or numbness. This allows certain kinds of procedures or surgery to be done without causing pain.
Cocaine can cause psychological dependence (a strong desire to continue using the medicine because of the "high" feeling it produces). This may lead to cocaine abuse (more frequent use and/or use of larger amounts of cocaine) and to an increased chance of serious side effects. Cocaine abuse has caused death from heart or breathing failure.
Use of cocaine as a local anesthetic for an examination or surgery is not likely to cause psychological dependence or other serious side effects. However, if cocaine is absorbed into the body too quickly, serious side effects can occur. Also, some people are especially sensitive to the effects of cocaine. Unwanted effects may occur in these people even with small amounts of the medicine. Before receiving cocaine as a local anesthetic, you should discuss its use with your doctor.
Cocaine is applied only by or under the immediate supervision of your doctor.
