Can you use secukinumab (Cosentyx) during pregnancy?
Secukinumab (Cosentyx) is an antibody that targets IL-17A. Whether it should be continued in pregnancy depends on the person’s underlying disease activity (most often plaque psoriasis, psoriatic arthritis, or ankylosing spondylitis) and the balance between maternal benefit and fetal risk. The available public prescribing information and pregnancy guidance typically emphasize individualized risk–benefit decisions with the treating dermatologist/rheumatologist and obstetric clinician.
What do pregnancy data say about secukinumab safety?
Human pregnancy experience with secukinumab is still limited compared with older, more widely studied biologics. Current knowledge largely comes from post-marketing reports and pregnancy registries/observational follow-up rather than large randomized trials. Clinicians usually look for reassuring signals such as no specific pattern of malformations emerging in reported cases, but uncertainty can remain because study sizes are often small.
Does stopping secukinumab reduce pregnancy risk—or increase it?
Stopping treatment may lower drug exposure to the fetus, but uncontrolled inflammatory disease can also increase pregnancy risks (for example, through systemic inflammation). For many patients, the clinical question is not “drug vs. no drug,” but whether disease control can be maintained safely with an alternative strategy. This is why decisions tend to be individualized rather than based on a single blanket rule.
What do doctors usually recommend if you’re already pregnant or planning pregnancy?
Common practical steps in real-world care include:
- Review disease severity and prior flares if biologic therapy is withheld.
- Discuss whether disease can be controlled with other options (often non-biologic approaches where feasible).
- Check the specific product label guidance for pregnancy and use in women who are trying to conceive.
- Coordinate care across specialties (prescriber plus OB).
How should secukinumab be timed around delivery?
Because the question of immunologic exposure at birth matters, clinicians may also consider timing in late pregnancy to reduce infant exposure, depending on the risk–benefit assessment. This can affect plans for newborn vaccination schedules and pediatric monitoring, particularly if the infant will receive live vaccines (practice varies by country and clinical protocol).
Are there breastfeeding considerations for secukinumab?
Breastfeeding guidance depends on whether maternal use continues postpartum and on how much drug is expected to transfer into breast milk. As with pregnancy, recommendations are typically individualized and based on available evidence from limited human data and the drug’s large-molecule properties.
What if you need to switch treatments in pregnancy?
Switching may be considered if there is a stronger safety signal for an alternative therapy for the patient’s condition, or if disease activity allows it. The choice often depends on the diagnosis (psoriasis vs. psoriatic arthritis vs. ankylosing spondylitis), past response, and prior pregnancy outcomes.
