Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with rheumatoid arthritis or ulcerative colitis. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth.
Based on published data, tofacitinib is present in human milk. Data on the effects of tofacitinib on the breastfed infant is limited to a small number of cases with no reported adverse effects. There are no data on the effects on milk production. Given the serious adverse reactions seen in patients treated with Tofacitinib Oral Solution, such as increased risk of serious infections, advise patients that breastfeeding is not recommended during treatment and for at least 18 hours after the last dose of Tofacitinib Oral Solution or 36 hours after the last dose of Tofacitinib (approximately 6 elimination half-lives).
There is uncertainty as to how these animal findings relate to females of reproductive potential treated with the recommended clinical dose. Consider pregnancy planning and prevention for females of reproductive potential.
Based on findings in rats, treatment with Tofacitinib Oral Solution may result in reduced fertility in females of reproductive potential. It is not known if this effect is reversible.
The safety and effectiveness of Tofacitinib Oral Solution for the treatment of active pcJIA have been established in patients 2 years to 17 years of age.
