                    Pregnancy & Lactation

                    Pregnancy

                    May cause fetal harm when administered to pregnant females

                    Data are not available on use in pregnant females

                    Verify pregnancy status in females of reproductive potential before initiation

                    Animal data

                    • Administration to pregnant mice during organogenesis resulted in adverse developmental outcomes (eg, alterations to growth, embryofetal mortality, structural abnormalities) at maternal exposures (AUC) comparable to 800-mg dose

                    Contraception

                    • Females of reproductive potential: Use effective contraception during treatment and for 1 month after last dose
                    • Males with female partners of reproductive potential: Use effective contraception during treatment and for 1 month after last dose

                    Infertility

                    • Based on findings from mice and dogs, male fertility may be impaired
                    • Trend for reversibility noted in dogs 30 days after last dose

                    Lactation

                    No data available on presence in milk, effects on breastfed children, or milk production

                    Pregnancy Categories

                    A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                    B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                    C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                    D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                    X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                    NA: Information not available.
