More Information About BLT Cream
Description: BLT Cream includes three topical anesthetics that are frequently found in OTC numbing creams but together in one formulation. The cream can be used before dermatological procedures, microneedling, Botox/filler injections, and more. This product helps make common dermatological procedures more comfortable for patients. It is stronger than the typical numbing cream with a higher total concentration of anesthetic.
BLT Cream Formulations
Several formulations of this topical anesthetic formulation are commonly compounded. The major difference in the first three is the strength of lidocaine. There is also a formulation available that does not include benzocaine.
Benzocaine 20%, Lidocaine 6%, Tetracaine 4%
Benzocaine 20%, Lidocaine 8%, Tetracaine 4%
Benzocaine 20%, Lidocaine 10%, Tetracaine 4%
Lidocaine 23%, Tetracaine 7%
BLT cream is frequently used by dermatologists but may also be used by dentists prior to injections of Botox for treating bruxism and temporomandibular disorders. It may also help during certain orthodontic procedures or in treating conditions affecting maxillofacial muscles.
Safety Considerations/Tips
The majority of patients will not experience side effects if used appropriately. However, there are many precautions that should be taken prior to using a compounded topical anesthetic like BLT cream. Although it is sometimes given to patients to use at home, this generally should not be done. BLT cream should be applied only by a trained healthcare provider as there is a high potential for misuse.
Any compounded topical anesthetic should be applied only to intact skin. If there is broken skin it should be allowed to heal before any procedure is performed when numbing is required.
Knowing what a toxic reaction to a numbing cream looks like is essential. Light headedness, a metallic taste, slurred speech, restlessness/anxiety, and more can be a sign of a reaction. A full list of potential side effects and contraindications will come with all orders.
BLT Cream Application
skin numbing cream - BLT cream with benzocaine, lidocaine, and tetracaine
Benzocaine/lidocaine/tetracaine cream is applied to the treatment area and allowed to sit for 15-20 minutes (sometimes a bit longer). The cream is completely removed before any procedure is started. A trained practitioner applies the cream using an applicator and gloved hand or simply a gloved hand. This will prevent any transfer of the anesthetic, which will numb the practitioner’s skin if it touches it.
