Pharmacotherapeutic group: Antipruritics, incl. Antihistamines, Anesthetics, etc;
ATC Code: D04 AB04
Benzocaine applied to the skin acts as a topical local anaesthetic, acting on nerve endings and receptors, temporarily reducing the itching and minor pain associated with various thermal, mechanical or chemical stimuli. The vanishing creme base also helps soothe, lubricate, and protect irritated skin.
When used as directed, some benzocaine applied topically may be absorbed through the skin and mucous membranes and is hydrolysed by esterases in the plasma and in the liver, but this should be of negligible consequence. Benzocaine has the quickest onset and shortest duration of action of the commonly used topical anaesthetics.
Local anaesthetics should not be used in patients with complete heart block.
Not for use on extensive body area or on the mouth or eyes or under conditions in which significant inhalation is likely.
None.
