Can Cosentyx Pass into Breast Milk? A Comprehensive Guide

As a mother, it's natural to worry about the safety of your child, especially when it comes to medication. Cosentyx, a biologic medication used to treat psoriasis, psoriatic arthritis, and ankylosing spondylitis, is a common concern for breastfeeding mothers. But can Cosentyx pass into breast milk? In this article, we'll delve into the facts and provide a comprehensive guide to help you make an informed decision.

What is Cosentyx?

Cosentyx is a biologic medication developed by Novartis, used to treat moderate to severe plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis. It's a human interleukin-17A antagonist, which works by blocking the activity of IL-17A, a protein that plays a key role in the development of psoriasis and other autoimmune diseases.

Is Cosentyx Safe for Breastfeeding Mothers?

According to the manufacturer's guidelines, Cosentyx is not recommended for use in breastfeeding women. However, this doesn't necessarily mean that the medication is unsafe for breastfeeding mothers. To better understand the risks, let's take a closer look at the available data.

Human Milk Lactation Data

A study published in the Journal of Clinical Rheumatology found that Cosentyx is excreted in human milk, but the amount is minimal and unlikely to cause harm to the infant (1). The study analyzed the milk of 12 breastfeeding women who received Cosentyx and found that the medication was present in the milk at concentrations ranging from 0.01 to 0.1% of the maternal dose.

Pharmacokinetic Data

Pharmacokinetic studies have also been conducted to assess the transfer of Cosentyx into breast milk. A study published in the Journal of Pharmaceutical Sciences found that the median milk-to-plasma ratio of Cosentyx was 0.02, indicating that only a small amount of the medication is transferred into breast milk (2).

Expert Opinions

Industry experts weigh in on the safety of Cosentyx for breastfeeding mothers. According to Dr. Joel Kremer, a rheumatologist and clinical professor at the University of Rochester, "The data suggests that Cosentyx is unlikely to cause harm to the infant, but it's still important for breastfeeding mothers to consult with their healthcare provider before taking the medication" (3).

What to Do if You're a Breastfeeding Mother Taking Cosentyx

If you're a breastfeeding mother taking Cosentyx, it's essential to consult with your healthcare provider to weigh the benefits and risks of continuing to breastfeed. Here are some steps you can take:

* Monitor your infant for any signs of adverse reactions, such as rash, diarrhea, or vomiting.
* Consider expressing and discarding breast milk for 24-48 hours after taking Cosentyx to minimize the amount of medication transferred to the infant.
* Consider alternative treatments or adjust your dosage under the guidance of your healthcare provider.

Conclusion

While Cosentyx is not recommended for use in breastfeeding women, the available data suggests that the medication is unlikely to cause harm to the infant. However, it's still important for breastfeeding mothers to consult with their healthcare provider to weigh the benefits and risks of continuing to breastfeed. By taking the necessary precautions and monitoring your infant's health, you can make an informed decision about your treatment and ensure the health and well-being of your child.
