Intravenous Immunoglobulin G administered by intravenous drip infusion at the clinic. Used as immune supportive therapy for patients with a history of recurrent miscarriage or repeated IVF failure and relevant immune or pregnancy-related findings. The first infusion is administered a few days before ovulation or egg collection, the second after a positive pregnancy test, and the third after a viable pregnancy has been confirmed by ultrasound scan at 6 to 7 weeks of gestation. Further immune assessment and support may follow. Treatment remains controversial, the evidence is debatable, and IVIg is prescribed off-label on a named patient basis. Possible side effects include headache, muscle pain, fever, chills and low back pain. Rare risks include thrombosis, kidney failure and anaphylaxis.
