What is Compounded BLT Cream (Benzocaine / Lidocaine / Tetracaine)?
This compounded preparation contains benzocaine, lidocaine, and tetracaine in a topical cream base (commonly called BLT cream), prepared by a licensed compounding pharmacy pursuant to an individual patient prescription. It is used for provider-directed topical anesthesia prior to dermatologic, aesthetic, or minor procedural interventions.
How does Compounded BLT Cream (Benzocaine / Lidocaine / Tetracaine) work?
BLT cream combines three local anesthetics with complementary mechanisms: benzocaine (ester type) and tetracaine (ester type) block peripheral nerve sodium channels at the site of application, while lidocaine (amide type) provides additional and more sustained anesthetic depth. The combination produces rapid onset of skin numbing with broader coverage than any single agent alone.
How to use Compounded BLT Cream (Benzocaine / Lidocaine / Tetracaine)
Apply only as directed by the clinician — typically to a precisely defined skin area for a specific time before the procedure. Use the smallest effective amount and only for the prescribed duration. Do not apply under occlusive dressings unless explicitly directed.
Compounded BLT Cream (Benzocaine / Lidocaine / Tetracaine) side effects
Temporary numbness, redness, and mild skin irritation at the application site are expected. Extensive or prolonged application can lead to systemic absorption and toxicity. Benzocaine may rarely cause methemoglobinemia — a condition where blood cannot carry oxygen effectively — particularly with large-area or prolonged use.
Drug interactions with Compounded BLT Cream (Benzocaine / Lidocaine / Tetracaine)
Systemic toxicity risk increases significantly with large application areas, broken skin, or occlusive dressings. Benzocaine-induced methemoglobinemia is a serious risk — do not use on mucous membranes, open wounds, or under occlusion without explicit prescriber direction. Inform all healthcare providers about use of this preparation before any procedure.
How to store Compounded BLT Cream (Benzocaine / Lidocaine / Tetracaine)
Store tightly closed at room temperature away from heat. Do not freeze. Protect from direct light. Use within the beyond-use date on the label.
Precautions for Compounded BLT Cream (Benzocaine / Lidocaine / Tetracaine)
Do not use on large skin areas, broken skin, or mucous membranes without specific prescriber instruction. Do not use in infants or young children unless specifically prescribed. Benzocaine may cause methemoglobinemia — seek emergency care for any signs of oxygen deprivation. Keep out of reach of children.
