Three cases of adverse reactions to repeated intramuscular botulinum toxin A (BTA) injections are described: a persistent rash on the face at the site of injection, a localized anaphylactic reaction following BTA injection into one leg, and bilateral ptosis repeatedly following BTA injection into neck muscles. The mechanisms for these idiosyncratic adverse responses are not known.
本文描述了3例重复肌内注射A型肉毒杆菌毒素（BTA）的不良反应：注射部位面部出现持续性皮疹、一侧腿部注射BTA后出现局部过敏反应，以及颈部肌肉注射BTA后反复出现双侧上睑下垂。这些特异质性不良反应的机制尚不清楚。
