Dysport, which is a neuromodulator used for cosmetic and therapeutic purposes, may have specific contraindications based on known allergies. An allergy to cow's milk is particularly relevant because some formulations of medications can include proteins derived from milk. For individuals with a cow's milk allergy, exposure to these proteins could provoke a serious allergic reaction.

In contrast, the other allergies listed—peanuts, soy, and shellfish—while important for patients to disclose, do not have a direct connection to the components typically found in Dysport formulations. Dysport contains botulinum toxin type A and an inactive ingredient system that may not pose the same risk for individuals with these allergies. Therefore, cow's milk allergy stands out as a significant contraindication, emphasizing the importance of a thorough medical history and allergy screening before administering Dysport to ensure patient safety.
