Medical Uses
Enflonsia (clesrovimab-cfor) is a respiratory syncytial virus (RSV) F protein-directed fusion inhibitor used for the prevention of RSV lower respiratory tract disease in neonates and infants who are born during or entering their first RSV season.
Recommended Dosage:
The recommended dose for neonates and infants born during or entering their first RSV season is 105 mg administered as a single intramuscular (IM) injection. For neonates and infants born during the RSV season, administer this therapeutic drug once starting from birth. For infants born outside the RSV season, administer the medicine once before the start of their first RSV season, considering the duration of protection provided by treatment.
Infants Undergoing Cardiac Surgery with Cardiopulmonary Bypass: For infants undergoing cardiac surgery with cardiopulmonary bypass during or entering their first RSV season, an additional 105 mg dose administered as an IM injection is recommended as promptly as the infant is stable after surgery to ensure adequate clesrovimab-cfor serum levels.
