Pregnancy and Lactation
Pregnancy
Guselkumab is contraindicated during pregnancy.
The manufacturer recommends avoiding the use of guselkumab during pregnancy as a precautionary measure. At the time of writing there is limited data from the use of guselkumab in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonic/foetal development, parturition or postnatal development. Risks are unknown.
Lactation
Guselkumab is contraindicated during breastfeeding.
The manufacturer advises that the patient either discontinues guselkumab or discontinues breastfeeding. It is not known whether guselkumab is excreted in human milk. A risk to the breastfeeding child cannot be excluded because immunoglobulins are excreted in human milk.
