Succimer Pregnancy Warnings

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.

US FDA pregnancy category: Not assigned

Animal studies showed teratogenicity and fetotoxicity when given during organogenesis at subcutaneous doses from 410 to 1640 mg/kg/day. Maternal toxicity and death occurred at 720 mg/kg/day or higher given during organogenesis, as well as pups with impaired reflexes. 510 mg/kg/day was the highest dose tolerated in pregnant rats. There are no controlled data in human pregnancy.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.
