What we know about taking Tinzaparin while pregnant
All pregnancies have a background risk of birth defects, loss, or other adverse outcome regardless of drug exposure. The fetal risk summary below describes the potential of INNOHEP® (tinzaparin) to increase the risk of developmental abnormalities above background risk.
Taking Tinzaparin While Breastfeeding
What are recommendations for lactation if you're taking Tinzaparin?
Although tinzaparin has not been studied, other low molecular weight heparins (e.g., dalteparin, enoxaparin) are not excreted into breastmilk in clinically relevant amounts. Because there is no published experience with tinzaparin during breastfeeding, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
Maternal / infant drug levels
