#BLT NUMBING CREAM SKIN#
It is recommended that the skin area that is to be topically anesthetized have no previous treatment with benzoyl peroxide or that the skin is thoroughly washed prior to the application of the anesthetic.

Investigators attributed the decreased anesthetic effect to a breakdown of the benzocaine molecule by either or both benzoyl peroxide or benzoyl peroxide-derived free radicals. In a clinical study, an estimated 75% increase in patient-reported, prick-induced pain was noted in areas treated with both 5% benzoyl peroxide and 6% benzocaine cream as compared to areas treated with 6% benzocaine cream alone. 1 2 3 5 6 7 InteractionsĪdapalene Benzoyl Peroxide: Concurrent use of benzoyl peroxide and topical anesthetics may decrease the efficacy of the anesthetic. If a breastfeeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA. Consider the benefits of breastfeeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. This drug combination has not been evaluated by the American Academy of Pediatrics (AAP), however lidocaine is classified as usually compatible with breastfeeding if an alternative is needed. Infant ingestion should be avoided because the benzocaine component has been associated with life threatening cases of methemoglobinemia in infants and children <= 2 years of age. In order to avoid infant ingestion, benzocaine lidocaine tetracaine should never be applied on or near the breast or nipple of a woman who is breastfeeding. However, when used appropriately, as a single dose applied topically to mucosal tissue, systemic absorption is expected to be minimal and unlikely to affect the nursing infant. It is not known whether the components of benzocaine lidocaine tetracaine are excreted in human milk. 1 2 3 A study by the American Dental Association provides some evidence that, when needed, the use of dental local or topical anesthetics at 13 weeks to 21 weeks of pregnancy or later is likely safe and does not raise incidences of adverse pregnancy outcomes or other adverse events the study analyzed data from the Obstetrics and Periodontal Therapy (OPT) trial, a multicenter study of over 800 pregnant patients in the early to mid second trimester who received required dental procedures. Manufacturers state that these products should not be used during early pregnancy, unless the healthcare provider judges the potential benefits outweigh the unknown hazards routine precaution for the use of any topical anesthetic should be observed. Safe use of benzocaine lidocaine tetracaine during pregnancy has not been established with respect to possible adverse effects upon fetal development. While systemic absorption of local anesthetics can produce effects on the central nervous and cardiovascular systems, systemic absorption of benzocaine lidocaine tetracaine is expected to be minimal with appropriate use. Direct nerve membrane penetration is necessary for effective anesthesia, which is achieved by applying the anesthetic topically to the area to be anesthetized. Clinically, loss of function occurs as follows: pain, temperature, touch, proprioception, and skeletal muscle tone. The blockade affects all nerve fibers in the following sequence: autonomic, sensory, and motor, with effects diminishing in reverse order.
This decreases the rate of membrane depolarization, thereby increasing the threshold for electrical excitability.
1 2 3 Mechanisms of Actionīenzocaine, lidocaine, and tetracaine are local anesthetics that cause a reversible blockade of nerve conduction by decreasing nerve membrane permeability to sodium. These products are not intended for prolonged application time or use. The potential for sensitization increases with the duration of contact, and can be avoided with appropriate application technique. Benzocaine, lidocaine and tetracaine are more likely than other local anesthetics to cause contact sensitization. These products are used for topical anesthesia and mild pain control.
