LET stands for Lidocaine, epinephrine and tetracaine, a drug abbreviation.

Topical anesthetic gel applied directly to lacerations, especially in children, to numb the wound before cleaning and suturing without a needle. It works in about 20 to 30 minutes, and the skin blanches when it has taken effect.

Example: LET gel applied to chin laceration at 1410; blanched and numb by 1435.

Usage notes

LET replaced the older TAC mixture, which contained cocaine and was more toxic and expensive. Traditionally it is avoided on fingers, toes, the nose tip and penis because of epinephrine, although that caution is debated. Pharmacies usually compound it. LET also abbreviates linear energy transfer in radiation physics.
