Cases of iatrogenic botulism have been reported following injection of botulinum toxin products. Patients and caregivers should be advised to seek immediate medical advice if they experience any signs or symptoms consistent with the spread of botulinum toxin effect or if swallowing, speech or respiratory disorders arise (see section 4.9). Most cases have been reported following the use of botulinum toxin containing products when used for unapproved indications and/or administration into unapproved injection sites or following use of higher than recommended doses and the use of unlicensed products.5
