Restasis vs Xiidra: Complete Comparison Guide
When artificial tears aren't enough to manage dry eye symptoms, your eye doctor may recommend prescription medications. Restasis and Xiidra are the two leading FDA-approved prescription eye drops for treating chronic dry eye disease. Understanding the differences between these medications can help you and your doctor choose the best treatment for your specific condition.
Understanding Chronic Dry Eye Disease
Chronic dry eye disease is an inflammatory condition affecting the ocular surface and tear-producing glands. Unlike temporary dryness from environmental factors, chronic dry eye involves ongoing inflammation that disrupts normal tear production and quality. This inflammation creates a vicious cycle: inadequate tears lead to surface damage, which triggers more inflammation, further reducing tear production.
Both Restasis and Xiidra work by targeting this underlying inflammation rather than simply lubricating the eye surface like artificial tears. This makes them fundamentally different from over-the-counter options and explains why they require a prescription and consistent use over time.
Restasis (Cyclosporine 0.05%)
How Restasis Works
Restasis contains cyclosporine, an immunomodulator that reduces inflammation in the lacrimal glands (tear-producing glands) and on the ocular surface. By suppressing the inflammatory response, Restasis helps your eyes produce more of their own natural tears.
- FDA Approved: 2003 (over 20 years of clinical use)
- Dosage: One drop in each eye twice daily (morning and evening)
- Time to Effect: 3-6 months for full benefit
- Mechanism: Increases natural tear production
Restasis Benefits
Restasis has the longest track record of any prescription dry eye medication, with extensive clinical data supporting its safety and effectiveness. Studies show that Restasis increases tear production in approximately 15-20% of patients and provides symptom relief for many more. The medication is particularly effective for patients with aqueous-deficient dry eye, where the lacrimal glands don't produce enough tears.
Restasis Side Effects
The most common side effect of Restasis is a burning or stinging sensation upon instillation, reported by about 17% of users. This typically improves over the first few weeks of use. Other potential side effects include:
- Eye redness
- Discharge or watering
- Blurred vision
- Eye pain or itching
Xiidra (Lifitegrast 5%)
How Xiidra Works
Xiidra contains lifitegrast, which works by blocking the interaction between two proteins (ICAM-1 and LFA-1) involved in the inflammatory cascade of dry eye disease. This targeted approach interrupts the inflammation cycle at a specific point.
- FDA Approved: 2016 (newer medication with modern formulation)
- Dosage: One drop in each eye twice daily (morning and evening)
- Time to Effect: 2 weeks to 3 months for symptom improvement
- Mechanism: Reduces both signs and symptoms of dry eye
Xiidra Benefits
Xiidra is the only medication FDA-approved to treat both the signs (objective clinical findings) and symptoms (patient-reported discomfort) of dry eye disease. Clinical trials showed that Xiidra provided symptom relief faster than Restasis, with some patients experiencing improvement within 2 weeks. The medication works well for patients with inflammatory dry eye regardless of whether the primary problem is tear production or tear quality.
Xiidra Side Effects
The most distinctive side effect of Xiidra is an unusual taste disturbance (dysgeusia), reported by about 16% of users. This metallic or bitter taste occurs because the medication can drain through the tear ducts into the throat. Other common side effects include:
- Instillation site irritation
- Reduced visual acuity
- Eye irritation or discomfort
- Blurred vision

| FDA Approval | 2003 | 2016 |
| Onset of Action | 3-6 months | 2 weeks to 3 months |
| Primary Effect | Increases tear production | Reduces inflammation |
| Most Common Side Effect | Burning/stinging | Taste disturbance |
| Cost (without insurance) | $400-600/month | $600-700/month |
Which Medication is Right for You?
The choice between Restasis and Xiidra depends on several factors, including your specific type of dry eye, symptom severity, tolerance for side effects, insurance coverage, and personal preferences. At The Last Optical, we conduct comprehensive dry eye evaluations to determine which medication is most likely to benefit you.
Important Considerations
- Both medications require consistent use: Skipping doses reduces effectiveness
- Patience is essential: Neither medication provides instant relief
- Artificial tears can be used concurrently: Continue using preservative-free tears as needed
- Insurance coverage varies: Check your plan's formulary and copay assistance programs
- Individual response varies: What works for one person may not work for another
Cost and Insurance Coverage
Both Restasis and Xiidra are expensive medications, with retail prices ranging from $400-700 per month. However, most insurance plans cover at least one of these medications, and both manufacturers offer copay assistance programs that can significantly reduce out-of-pocket costs for eligible patients.
Generic cyclosporine (the active ingredient in Restasis) became available in 2022, offering a more affordable option for some patients. Xiidra does not yet have a generic equivalent. Our team at The Last Optical can help you navigate insurance coverage and manufacturer assistance programs to make treatment affordable.
Beyond Prescription Eye Drops
While Restasis and Xiidra are valuable tools in managing chronic dry eye, they're most effective as part of a comprehensive treatment plan. At The Last Optical, we combine prescription medications with advanced therapies like OptiLight IPL, TearCare, and customized nutritional supplementation for optimal results.
Many patients find that addressing the root cause of their dry eye—whether it's meibomian gland dysfunction, environmental factors, or systemic conditions—provides better long-term relief than medication alone. Our dry eye specialists take a holistic approach to identify and treat all contributing factors.
