Ranibizumab

Drug Levels and Effects:




Summary of Use during Lactation:


One infant was breastfed, apparently without noticeable harm, following maternal intravitreal ranibizumab injections. Vascular endothelial growthfactor(VEGF) levels in breastmilk were not changed following the injection. Because the breast and neonatal intestine have VEGF receptors, some authors recommend use of intravitreal ranibizumab over bevacizumab, which does appear to depress milk VEGF levels.[1]

Maternal Levels.

A woman was given 3 intravitreal injections of bevacizumab for scar-associated choroidal neovascularization in her left eye. Vascular endothelial growthfactor(VEGF) was measured in serum and breastmilk. After the intravitreal injection of bevacizumab, the VEGF level in breastmilk decreased from 13.3 to 8.6 mcg/L over a 2-week period. After changing therapy to ranibizumab therapy, no decrement in breastmilk VEGF was seen during the 42 days following injection.[1]
