Certolizumab pegol is anti TNF alpha drug used to treat rheumatoid arthritis, Crohn’s disease, psoriatic arthritis, and ankylosing spondylitis. What makes it different is that it is the first drug I can remember which has been licensed for use in pregnancy and in breastfeeding. This means that the manufacturer in applying for marketing authority has accepted that it is safe. www.medicines.org.uk/emc/product/7387/smpc
Recently I have found myself suggesting it to mothers who are at the point of needing methotrexate to control their symptoms and therefore needing to stop breastfeeding.
I have to congratulate the manufacturer UCB Pharma on taking this very positive step and hope others follow suite. Please note I have no links financial or otherwise with them.
