Calcitonin Salmon Interactions

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary There are no studies with calcitonin salmon injection in pregnant women to inform a drug associated risk for birth defects or miscarriage. In an animal reproduction study, subcutaneous administration of calcitonin salmon to pregnant rabbits during organogenesis at 4 to 18 times the recommended parenteral human dose caused a decrease in fetal birth weights. No adverse developmental outcome was observed in the rat with subcutaneous administration of calcitonin salmon at 9 times the recommended human parenteral dose based on body surface area (see Data ). In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Calcitonin salmon has been shown to cause a decrease in fetal birth weights in rabbits when given by subcutaneous injection in doses 4 to 18 times the parenteral dose recommended for human use (of 54 International Units/m 2 ). No embryo/fetal toxicities related to calcitonin salmon were reported from maternal subcutaneous daily doses in rats up to 80 International Units/kg/day from gestation day 6 to 15.
