Animal studies have failed to reveal evidence of embryofetal toxicity or teratogenicity. In pregnant rats administered subcutaneous doses up to 45 times the maximum recommended human dose (MRHD) in women based on body surface area (BSA), no effects on embryofetal survival or fetal body weights and no drug-related fetal malformations were observed; in pregnant rabbits administered subcutaneous doses up to 90 times the MRHD based on BSA, decreases in maternal food consumption and maternal body weight gains were observed but there were no drug-related fetal findings. There are no controlled data in human pregnancy.
