Insights
Topical propranolol for infantile hemangioma can cause temporary blanched skin patches due to vasoconstriction. Proper application instructions are crucial to prevent this reversible side effect.
Area of Science:
- Dermatology
- Pediatrics
- Pharmacology
Background:
- Infantile hemangiomas are common vascular tumors in infants.
- Topical propranolol is an emerging treatment for superficial infantile hemangiomas.
- Understanding potential side effects of topical propranolol is essential for safe and effective use.
Observation:
- A 3-month-old infant developed blanched macules on the forehead after topical propranolol treatment for an infantile hemangioma.
- The blanched macules appeared at the site of propranolol application.
Findings:
- Topical non-selective beta-blockers, like propranolol, can cause peripheral vasoconstriction.
- This vasoconstriction leads to the observed blanched macules, a potential side effect of topical propranolol.
- The side effect was associated with overuse and was reversible upon appropriate management.
Implications:
- This case highlights the importance of precise application techniques and dosage instructions for topical propranolol.
- Healthcare providers should educate caregivers about potential side effects and proper usage.
- Further research may explore optimal dosing and application methods to minimize adverse events.
Abstract:
We describe a 3-month-old child with an infantile hemangioma on the forehead with a blanched macule provoked by topical treatment with propranolol. This observation demonstrates that topically applied (non-selective) beta-blockers may induce blanched macules at the site of application, a side effect due to peripheral vasoconstriction of blood vessels by non-selective beta-2 blockade. This side effect was linked due to overuse and was reversible. This case illustrates the importance of providing thorough instructions regarding topical propranolol application.
