Monitor Closely (1)
- efgartigimod alfa
efgartigimod alfa will decrease the level or effect of Rho(D) immune globulin by receptor binding competition. Use Caution/Monitor. Coadministration of efgartigimod with medications that bind to the human neonatal Fc receptor may lower systemic exposures and effectiveness of such medications. Closely monitor for reduced effectiveness of medications that bind to the human neonatal Fc receptor. If long-term use of such medications is essential, consider discontinuing efgartigimod and using alternative therapies.

Warnings
Black Box Warnings
Intravascular Hemolysis (IVH) with WinRho SDF
- Intravascular hemolysis (IVH) leading to death has been reported in patients treated for ITP with WinRho SDF
- IVH can lead to clinically compromising anemia and multisystem organ failure including acute respiratory distress syndrome (ARDS)
- Serious complications, including severe anemia, acute renal insufficiency, renal failure and disseminated intravascular coagulation (DIC) have also been reported
- Monitor closely in health care setting for at least 8 hr after administration
- Perform dipstick urinalysis at baseline, 2 hr, and 4 hr after administration and prior to end of the monitoring period
- Alert patients to signs and symptoms of IVH, including back pain, shaking chills, fever, and discolored urine or hematuria
- Absence signs and/or symptoms of IVH within 8 hr do not indicate IVH cannot occur subsequently
- Post-treatment laboratory tests should be performed if IVH suspected and include plasma hemoglobin, urinalysis, haptoglobin, LDH, and plasma bilirubin (direct and indirect)
Contraindications
Hemolytic Disease
- Rho(D)+
- Rho(D) negative women who are Rh immunized
- Hypersensitivity to immune globulins
Immune Thrombocytopenic Purpura
- Rho(D) negative individuals
- Splenectomized individuals
- Hypersensitivity to plasma products
- Autoimmune hemolytic anemia
- Pre-existing hemolysis or high risk for hemolysis
- Do not use WinRho SDF in patients with IgA deficency with antibioies against IgA
Cautions
NEVER GIVE TO NEONATE
Do not administer IM for ITP
WinRho SDF: risk of rare but potentially fatal intravascular hemolysis in ITP pts
Maltose-containing IVIG products (eg WinRho SDF) may give false highs in certain glucose-testing systems
Avoid live vaccines for 3 mth
IgA deficiency
Avoid gluteal IM if possible, if not inject only in upper outer quadrant
Pregnancy & Lactation
Pregnancy Category: C
Lactation: not known if excreted in breast milk, no adverse effects reported
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Anti-Rho(D) immune globulins from human donors

Administration
IM
Administer to mother, not to infant
Administer into the deltoid muscle or upper outer side of the thigh
Do not use gluteal region as routine inj site (risk of injury to sciatic nerves), however if necessary, use only the upper, outer quadrant of gluteal muscle
The plunger of the syringe should be drawn back before injection to ensure that the needle is not in a blood vessel
If blood or any unusual discoloration is present in the syringe, withdraw needle &discard syringe; administer new dose of Rho(D) IGIM at a different site using a new syringe & needle
Do not adminster RhoD IGIM by IV; however, RhoD IGIV may be administered IM
Do NOT administer IM for ITP treatment
WinRho SDF: dilute 600 IU & 1500 IU in 1.25 mL supplied diluent(s); for 5000 IU vial, use 8.5 mL
IV
For Rh suppression, administer to mother & not infant
Reconstitute vial contents with appropriate volume of NS by injecting supplied diluent (NS) slowly onto the inside wall of the vial & swirl vial gently until the lyophilized pellet has dissolved
Do not shake vial. Inspect for particulate matter and discoloration prior to administration
For 600 IU or 1500 IU vials, use 2.5 mL diluent; for 5000 IU vial, use 8.5 mL
Do not administer with other drugs
Administer direct injection Rhophylac at 2 mL/15-60 sec; WinRho SDF 1500 IU/5-15 sec
