Xiidra Eye Drops (Lifitegrast 5%)
Xiidra (lifitegrast 5%) is a prescription ophthalmic solution indicated for the treatment of the signs and symptoms of dry eye disease. As a lymphocyte function-associated antigen-1 (LFA-1) antagonist, Xiidra targets ocular surface inflammation to relieve dryness, irritation, and discomfort.
Overview of Xiidra for Dry Eye Disease
Dry eye disease (DED) is a chronic, multifactorial condition affecting the tear film and ocular surface. It can cause persistent irritation, blurred vision, burning sensations, and fluctuating visual clarity. Inflammation plays a central role in the development and progression of this condition.
Xiidra contains lifitegrast 5%, an innovative small-molecule integrin antagonist designed specifically to interrupt inflammatory pathways associated with dry eye disease. Unlike lubricating artificial tears that temporarily supplement moisture, Xiidra addresses an underlying inflammatory mechanism contributing to chronic symptoms.
Clinical guidance from the National Institute for Health and Care Excellence (NICE) and information provided by the NHS on dry eye syndrome emphasise that persistent dry eye often requires targeted pharmacological management in addition to lifestyle and environmental measures.
What Is Xiidra Used For?
Xiidra is indicated for the treatment of both the signs and symptoms of dry eye disease. It is suitable for adults experiencing chronic dryness, ocular surface inflammation, burning, stinging, and visual disturbances related to tear film instability.
- Relief of eye dryness and irritation
- Reduction of ocular surface inflammation
- Improvement of tear film stability
- Management of chronic inflammatory dry eye
How Xiidra Works: Targeting Ocular Inflammation
Xiidra functions as a lymphocyte function-associated antigen-1 (LFA-1) antagonist. LFA-1 is a cell surface protein expressed on T lymphocytes. It binds to intercellular adhesion molecule-1 (ICAM-1), which is upregulated in inflamed ocular tissues.
In dry eye disease, increased ICAM-1 expression promotes T-cell activation and migration to the ocular surface, perpetuating inflammation. Lifitegrast blocks the LFA-1/ICAM-1 interaction, reducing inflammatory signalling and helping to restore a healthier tear film environment.
Clinical trials have demonstrated that some patients may begin to notice symptomatic improvement within two weeks, although response times vary. Consistent twice-daily use is essential for sustained therapeutic benefit.
Xiidra Dosage and Usage Instructions
Recommended Dosage
The standard dosage is one drop in each eye twice daily, approximately 12 hours apart. Treatment adherence is crucial for optimal symptom control.
Step-by-Step Application Guide
- Wash hands thoroughly before handling the medication.
- Remove one single-use container from the foil pouch.
- Twist off the cap without allowing the tip to touch any surface.
- Tilt your head backwards and gently pull down the lower eyelid.
- Instil one drop into the conjunctival sac of each eye.
- Close your eyes gently for a few seconds.
- Discard the container immediately after use.
Contact Lens Guidance
Contact lenses should be removed prior to instillation. Wait at least 15 minutes before reinserting lenses.
Missed Dose Advice
If a dose is missed, administer it as soon as remembered unless it is close to the next scheduled dose. Do not apply double doses.
Side Effects of Xiidra
Common Side Effects
- Eye irritation or discomfort upon instillation
- Conjunctival redness
- Blurred vision immediately after application
- Dysgeusia (unpleasant taste sensation)
- Increased tearing or light sensitivity
Rare but Serious Reactions
- Allergic reactions, including swelling of the throat or tongue
- Wheezing or breathing difficulty
Seek immediate medical attention if symptoms of a severe allergic reaction occur.
Storage and Handling Instructions
- Store at 15°C to 30°C.
- Keep single-use containers in the original foil pouch until needed.
- Protect from light exposure.
- Discard each container immediately after use.
Proper storage maintains medication integrity and reduces contamination risk.
Diabetes-Related Dry Eyes and Xiidra
Individuals with diabetes may experience dry eye symptoms due to neuropathy, reduced tear production, and chronic inflammation associated with elevated blood glucose levels. Tear film instability can contribute to discomfort, blurred vision, and increased infection risk.
Xiidra’s anti-inflammatory mechanism makes it a potential therapeutic option for diabetic patients experiencing persistent dry eye disease. However, glycaemic control remains a critical component of overall ocular health.
Patients with diabetes should consult both their ophthalmologist and primary care physician before initiating treatment.
