Warnings
5 WARNINGS AND PRECAUTIONS Accidental Exposure to IMLYGIC: Accidental exposure may lead to transmission of IMLYGIC and herpetic infection. Healthcare providers and close contacts should avoid direct contact with injected lesions, dressings, or body fluids of treated patients. Accidental Exposure to IMLYGIC continued: Healthcare providers who are immunocompromised or pregnant should not prepare or administer IMLYGIC. If accidental exposure occurs, exposed individuals should clean the affected area. ( 5.1 ) Herpetic Infection: Patients who develop herpetic infections should be advised to follow standard hygienic practices to prevent viral transmission. 4 CONTRAINDICATIONS Immunocompromised Patients ( 4.1 ) Pregnant Patients ( 4.2 ) 4.1 Immunocompromised Patients IMLYGIC is a live, attenuated herpes simplex virus and may cause life-threatening disseminated herpetic infection in patients who are immunocompromised.
Pregnancy
8.1 Pregnancy Risk Summary Adequate and well-controlled studies with IMLYGIC have not been conducted in pregnant women. No effects on embryo-fetal development have been observed in a study conducted in pregnant mice. The design of the study limits application of the animal data to humans [see Data]. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
