The same day within 4 hours, the patient had severe pain, stiffness, swelling. Corrective treatment: not reported for severe pain, stiffness and swelling outcome: unknown for all events an investigation was initiated as a result of an unexpected increase in the number of labelled adverse events received from the us market for synvisc one, lot 7rsl021. The product met all release testing at time of manufacture in june 2017. Retain samples were retested due to the unexpected increase in adverse events. Higher than expected endotoxin results were obtained. In addition, the presence of microbial contamination was also confirmed. The cause of these events was under investigation. Once this investigation would be completed, corrective and preventive actions would be implemented. Seriousness criteria: medically significant for all events. Pharmacovigilance comment: sanofi company comment dated 29-mar-2018. This case concerns a patient who received treatment with synvisc one injection from recall lot and later experienced pain, stiffness and swelling. Since events occurred few hours after administration of synvisc one injection, significant temporal relationship can be established. Furthermore, the concerned lot number has been identified to have malfunction by the company. Therefore, the causal relationship of the events to the products cannot be excluded.
