Lifitegrast, known commercially as Xiidra, marks a pivotal development in treating dry eye disease by addressing the inflammation at its core. As a novel LFA-1 antagonist, it offers rapid relief for those with moderate to severe symptoms. Explore its administration, benefits, cost considerations, and potential side effects to make informed decisions about eye health.
Understanding Lifitegrast and Its Role in Treating Dry Eye Disease
Lifitegrast, marketed under the brand name Xiidra, is a groundbreaking ophthalmic solution designed to treat dry eye disease (DED). As the first new medication approved for this condition in over a decade, lifitegrast offers a novel approach by targeting the inflammation that underlies dry eye symptoms. It belongs to a class of medications known as lymphocyte function-associated antigen-1 (LFA-1) antagonists, which work by inhibiting T-cell inflammation. This is achieved by blocking the interaction between LFA-1 and intercellular adhesion molecule 1 (ICAM-1), thereby reducing the inflammatory response in the eye (source).
How Lifitegrast Provides Relief
Lifitegrast is administered as eye drops, typically instilled in each eye twice a day, approximately 12 hours apart. This regimen is crucial for maintaining the medication’s effectiveness. The drops come in single-use containers, ensuring hygiene and reducing the risk of contamination. Patients are advised to use the liquid immediately after opening and discard the container after use (source). Clinical trials have demonstrated that lifitegrast can significantly improve symptoms of DED as early as day 14, offering quicker relief compared to other treatments like cyclosporine (Restasis) (source).
Who Can Benefit from Lifitegrast?
Lifitegrast is particularly beneficial for patients with moderate to severe dry eye symptoms who have not found relief with over-the-counter treatments such as artificial tears. It is suitable for adults aged 17 and older and is not approved for use in children under 17. The medication is well-tolerated, with no serious ocular adverse events reported in clinical trials. However, patients should inform their healthcare provider about any allergies, current medications, and if they are pregnant or breastfeeding before using lifitegrast (source).
Cost and Accessibility
While lifitegrast is more expensive than over-the-counter treatments, it offers a significant advantage for those who have not responded to less costly options. A one-month supply of lifitegrast costs approximately $527, compared to about $24 for a 30-day supply of Refresh Plus lubricant eye drops (source). Xiidra offers a savings program for eligible patients with commercial insurance, allowing them to pay as little as $0 for their prescription. However, this offer is not valid for patients whose prescriptions are covered by federal or state healthcare programs (source).
Potential Side Effects and Considerations
Common side effects of lifitegrast include blurred vision, itchy or irritated eyes, tearing, headache, and throat irritation. Patients should report severe or persistent side effects to their doctor. It is important to remove contact lenses before application and wait 15 minutes before reinserting them. Proper storage involves keeping the medication in its original container, protected from light, and out of reach of children. Unused medication should be disposed of through a medicine take-back program to prevent accidental ingestion (source).
