Can you take Dupixent a day early?

Official Answer by Drugs.com

There is not enough information to know if it is safe to take Dupixent (dupilumab) any time earlier than the recommended dosing schedule. Clinical studies have not evaluated the effects of taking Dupixent ahead of schedule. Administering your dose too early may cause excess medication to accumulate in your body, potentially increasing the risk of side effects. If you believe you need to take your dose early, consult your healthcare provider for guidance.

Why does Dupixent cause eye problems?

Dupixent is associated with several different eye problems, including conjunctivitis, blepharitis, dry eyes, itchy eyes, and keratitis. The cause of the eye problems is thought to be due to Dupixent blocking interleukin-13 (IL-13), an inflammatory protein that also stimulates the production of goblet cells. Goblet cells are responsible for creating mucus in the eye and ensuring the stability of tears. So when Dupixent blocks IL-13 it also lowers the numbers of epithelial goblet cells leading to eye inflammation and eye problems. Continue reading

Dupixent calms an overreactive immune system but does not suppress the immune system. This leads to fewer and less severe episodes of inflammation when used to treat conditions such as eczema, asthma, COPD, rhinosinusitis, esophagitis, chronic urticaria, prurigo nodularis, and bullous pemphigoid.
