Event Description
Suspected vascular occlusion [vascular occlusion]. Bruise [injection site bruising]. Rha4 to the lower face, mental crease and chin area [off label use]. United states report received from a healthcare professional on (b)(6) 2022. A nurse practitioner who was also the prescriber and injector reported that a female patient of unknown age received a follow-up dose of rha4 for mental crease, on (b)(6) 2022; dose and frequency were not reported. An unknown volume of rha4 injection was applied to the lower face, chin area and mental crease using an unknown injection technique. The needle was used from the box. A cannula was not used for the administration of the rha4 product. Previous cosmetic procedures were not provided. Medical history was not provided. Concomitant medications, and food supplements were not provided. On (b)(6) 2022, during an evaluation, a patient was injected with an unknown amount of rha 4 to the lower face, mental crease, and chin area, immediately following the injection, a bruise developed very quickly. On an unknown date, the prescriber suspected the patient experienced a vascular occlusion. As a treatment the patient had aspirin, heat compress, massage, dissolving the filler with hyaluronidase, and lidocaine without epi to help numb the area. The outcome of the events was resolved. The product was not available for return. (b)(4). No additional information was available at the time of this report. Case comment: a causal relationship between the reported vascular occlusion and rha4 is assessed as possible based on the compatible temporal relationship and the lack of alternative etiologies that can be identified based on the reported information. The company will continue monitoring the benefit-risk profile for the product.
