-Treatment with this drug may lead to a decrease in serum vitamin A levels. Vitamin A supplementation is advised for patients under treatment. Vitamin A is essential for normal embryofetal development; however, excessive levels of vitamin A are associated with adverse developmental effects.

Studies in pregnant rats showed that subcutaneous administration during organogenesis period resulted in embryofetal mortality at high doses and reduced fetal body weigh at mid and high doses, which were associated with maternal toxicity.
Subcutaneous administration in rabbits and in rats throughout pregnancy and lactation periods showed no adverse effects on embryofetal development or development effects on the offspring. 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.
