A topical anesthetic cream, EMLA, can rarely cause severe allergic reactions like anaphylactic shock. This case highlights the importance of recognizing rare but serious adverse events associated with common dermatological treatments.
Area of Science:
- Dermatology
- Anesthesiology
- Allergy and Immunology
Background:
- Topical Eutectic Mixture of Local Anesthetics (EMLA) is widely used in dermatology for aesthetic procedures.
- While generally safe with mild local reactions, rare systemic toxicities like methemoglobinemia, CNS toxicity, and cardiotoxicity are documented.
- Anaphylaxis is a critical, albeit uncommon, adverse reaction to topical anesthetics.
Observation:
- A patient developed anaphylactic shock following the topical application of EMLA.
- The event occurred in a clinical setting during a routine dermatological procedure.
- Immediate medical intervention was required to manage the anaphylactic reaction.
Findings:
- This case represents a rare instance of anaphylactic shock attributed to topical EMLA.
- It underscores that even commonly used topical agents can precipitate severe hypersensitivity reactions.
- Diagnostic workup confirmed anaphylaxis as the cause of the patient's severe reaction.
Implications:
- Clinicians should maintain a high index of suspicion for rare allergic reactions to EMLA.
- Awareness of potential anaphylaxis is crucial for prompt diagnosis and management in dermatological practice.
- This case emphasizes the need for vigilance regarding adverse drug reactions in aesthetic dermatology.

Local Anesthetics: Common Agents and Their Applications
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
