Does Cosentyx affect a woman's ability to conceive?
Cosentyx (secukinumab) is a monoclonal antibody that targets interleukin-17A and is approved for psoriasis, psoriatic arthritis, and ankylosing spondylitis.

Does Cosentyx reduce fertility?
No human clinical trials have shown that secukinumab lowers ovarian reserve, disrupts ovulation, or reduces sperm quality in partners. Preclinical animal studies also found no impairment of fertility at doses several times higher than those used in patients.

What happens if a woman becomes pregnant while taking Cosentyx?
Limited human data exist. A pregnancy registry and post-marketing reports through 2023 have not identified a clear pattern of birth defects, but the numbers remain small. Current prescribing information recommends stopping the drug before conception unless the benefit outweighs potential risk.

How long should a woman wait after the last dose before trying to conceive?
Because the drug's half-life is roughly 25–30 days, most clinicians suggest waiting about five half-lives (roughly five months) to minimize fetal exposure. Individual decisions depend on disease severity and the availability of alternative therapies.

Are there differences between stopping Cosentyx versus switching to another biologic?
Women who discontinue secukinumab may experience disease flare. TNF inhibitors such as certolizumab pegol have more extensive pregnancy safety data and are sometimes chosen as alternatives when conception is planned.

When does the Cosentyx patent expire?
The primary U.S. composition-of-matter patent is listed to expire in 2029, with possible pediatric or regulatory extensions. Biosimilar developers are already filing challenges, which could affect future pricing and access.
