Two cases of herpes zoster appearing after botulinum toxin type a injections.
Two patients under the authors' care developed facial herpes zoster that erupted soon after cosmetic treatment with botulinum toxin type A (BTA). Both patients received typical doses of BTA in the glabella, forehead, and lateral periorbital areas. Within one week after treatment, each patient began experiencing symptoms of herpes zoster in one of the dermatomes supplied by the trigeminal nerve. Since the resolution of the herpes zoster, both patients have gone on to receive further treatments of BTA with prophylactic oral antivirals without sequelae.
