Upadacitinib

Limited compatibility

Unsafe. Moderate/severe adverse effects. Compatible under certain circumstances. Follow-up recommended. Use safer alternative or discontinue breastfeeding from 5 to 7 T ½ . Read Commentary.

Upadacitinib is an oral selective Janus kinase (JAK)1 inhibitor used in the treatment of moderate to severe rheumatoid arthritis, active psoriatic arthritis, ankylosing spondylitis and severe atopic dermatitis, including in patients who have not responded well to other therapies. Oral administration in a daily dose.

At the date of the last update we found no published data on its excretion in breast milk.

Its pharmacokinetic data do not allow a good prediction of its possible excretion in breast milk, because although its high volume of distribution would make it difficult, its low molecular weight and fixation to plasma proteins would facilitate it.

Its frequent side effects are respiratory infections, anemia, neutropenia, lymphopenia and elevated liver enzymes.

Pending further published data on this drug in relation to lactation, safer known alternatives are preferable, especially during the neonatal period and in case of prematurity.

Alternatives

  • Adalimumab (Safe product and/or breastfeeding is the best option.)

  • Infliximab (Safe product and/or breastfeeding is the best option.)
  • Tocilizumab (Safe product and/or breastfeeding is the best option.)
  • Tofacitinib (Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.)

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
