Xiidra vs Restasis: Effectiveness, Cost, and Safety
Understanding Dry Eye Disease and Why It Needs Treatment
Chronic dry eye is more than occasional discomfort. It is a cycle of inflammation and damage that, without treatment, can gradually worsen over time. Knowing what causes it and recognizing when you need more than over-the-counter drops is the first step toward real relief.
Dry eye develops when your eyes do not produce enough tears or when tears evaporate too quickly. Contributing factors include aging, certain medications, conditions like arthritis or thyroid disease, and environmental exposures. When the eye surface stays dry, the immune system responds with inflammation, which then damages the glands that make tears, creating a self-reinforcing cycle.
Unlike the temporary dryness you might feel after staring at a screen, chronic dry eye disease persists for months or years and requires treatment that goes beyond simple lubrication.
Some symptoms point to a level of dry eye that prescription therapy can address more effectively than drops alone. Pay attention to patterns that interfere with your daily activities or persist despite using over-the-counter products.
- Persistent burning or stinging that artificial tears do not fully relieve
- Gritty or sandy sensations throughout the day
- Blurry vision that clears temporarily when you blink
- Difficulty wearing contact lenses comfortably
- Excessive tearing as your eyes attempt to compensate for dryness
- Eye fatigue that affects reading, driving, or screen time
Our team uses a thorough exam to understand exactly what type of dry eye you have and how severe it is. This allows us to match your treatment to your specific condition rather than taking a one-size-fits-all approach.
- Schirmer test to measure how much tear fluid your eyes produce
- Tear breakup time to assess how stable your tear film is
- Ocular surface staining to identify areas of corneal or conjunctival damage
- Meibomian gland evaluation and meibography to assess the oil-producing glands in your eyelids
- Tear osmolarity and MMP-9 testing to detect inflammation markers
Our specialists, including Dr. Christopher Newton and Dr. Whitney Catanio, are experienced in identifying the root causes of dry eye, whether related to the corneal surface, eyelid glands, or post-surgical changes.
We consider prescription treatment when artificial tears and lifestyle adjustments are not providing lasting relief, or when we find clinical signs of inflammation or significant reduction in tear production. Treating the underlying inflammation rather than just supplementing tears gives your eyes the best chance to heal and recover long-term function.
For patients preparing for cataract or refractive surgery, optimizing the ocular surface beforehand is especially important. Our team routinely evaluates and treats dry eye as part of surgical preparation to help ensure accurate measurements and a smooth recovery.
How Xiidra and Restasis Work
Both Xiidra and Restasis reduce the inflammation that drives chronic dry eye disease, but they target different steps in the inflammatory process. Understanding how each one works helps explain why one might suit you better than the other.
When your eyes are dry, immune cells release signals that damage the glands and cells responsible for producing healthy tears. This inflammation makes dryness worse, which in turn drives more inflammation. Breaking this cycle is the goal of both prescription medications, and it is why treating inflammation directly produces more lasting results than artificial tears alone.
Restasis contains cyclosporine, a medication that suppresses the activity of specific immune cells in the eye. By blocking the signals that trigger inflammation, cyclosporine allows the tear-producing glands to recover and produce more natural tears over time. It is available as a 0.05% ophthalmic emulsion and requires consistent, long-term use to maintain its benefits.
- Suppresses T-cell activity that drives ocular surface inflammation
- Helps restore the natural tear production capacity of the lacrimal glands
- Works gradually, with meaningful improvement typically seen after three to six months
Xiidra contains lifitegrast, which works by blocking a specific protein interaction that immune cells use to communicate and amplify inflammation on the eye surface. By interrupting this signal at an earlier point in the inflammatory process, Xiidra reduces both the signs and the symptoms of dry eye disease. Because it works through a different pathway than cyclosporine, patients who do not respond to one medication may respond to the other.
Both medications require patience. Xiidra tends to produce noticeable symptom improvement more quickly, with many patients reporting some relief within two weeks, though full benefits may take six to twelve weeks. Restasis typically takes three to six months before patients feel a meaningful difference, though some notice changes sooner. In some cases, we may recommend a short course of a low-risk steroid drop during the first few weeks of cyclosporine use to bridge the gap and improve early comfort.
Comparing the Effectiveness of Xiidra and Restasis
Both medications have been shown in clinical studies to reduce the signs and symptoms of dry eye disease, but they perform somewhat differently depending on the outcome being measured. We consider these differences when personalizing your treatment plan.
Clinical trials for Xiidra demonstrated significant improvements in both patient-reported symptoms and clinically visible signs of dry eye disease. Participants experienced better relief from discomfort and reduced inflammatory markers on the eye surface. A meaningful number of patients reported symptom improvement within the first two weeks, with continued benefit through the twelve-week study period.
Restasis has an extensive body of research supporting its ability to increase tear production in patients with chronic dry eye. Clinical trials found that a significant portion of patients produced more tears after consistent use compared to those using a placebo. Long-term use has been shown to maintain these improvements in tear volume and symptom control. Stopping the medication early reduces the likelihood of experiencing full benefit.
Xiidra generally provides faster symptom relief, with some patients noticing improvement within the first two weeks of use. Restasis typically requires several months before patients feel significant relief. If quicker comfort is a priority, this difference matters in choosing where to start. However, faster onset does not necessarily mean one medication is superior in the long run, and we reassess your response as treatment progresses.
Restasis has been shown to increase measurable tear volume in a subset of patients, which is particularly helpful when tear deficiency is the primary problem. Xiidra focuses more on reducing inflammation and improving the overall quality and stability of the tear film, with less consistent evidence for directly increasing tear volume. Both approaches support healthier tear function over time by addressing ocular surface inflammation.
- Restasis directly increases tear volume in many patients
- Xiidra reduces inflammatory markers and improves tear film stability
- Both medications support long-term ocular surface health by calming inflammation
Individual responses vary, and we cannot always predict in advance which medication will be more effective for a specific person. The severity and cause of your dry eye, your overall health, and your tolerance for side effects all influence the outcome. Our eye doctors consider your exam findings, symptom profile, and goals when making the initial recommendation. If the first medication does not provide adequate relief after a fair trial, switching to the other is a reasonable and safe option.
Side Effects and Safety
Both medications are generally well tolerated, but each has a distinct side effect profile. Knowing what to expect makes it easier to use your drops consistently and recognize when something needs our attention.
The most commonly reported side effect of Xiidra is a temporary altered taste sensation, often described as a bitter or unusual taste in the mouth shortly after instilling the drops. This happens because drops can travel through the tear ducts into the nose and throat. Pressing gently on the inner corner of your closed eyelids for one to two minutes after each dose, a technique called punctal occlusion, reduces how much of the medication drains into your throat and can help minimize this sensation.
- Altered or bitter taste that usually fades within minutes
- Mild burning or stinging upon instillation
- Temporary blurred vision immediately after use
- Eye discomfort, irritation, or redness
Burning or stinging upon instillation is the most frequently reported side effect of Restasis, especially during the first few weeks of use. This typically improves as your eyes adjust to the medication. Storing the drops at room temperature or slightly chilled, and inverting the single-use vial several times before use to ensure the emulsion is uniform, can help reduce discomfort at instillation.
- Burning or stinging that often lessens over time
- Eye redness or watery eyes
- A foreign body sensation in the eye
Serious side effects from either medication are uncommon, but there are warning signs that require prompt evaluation. Contact us right away if you experience any of the following after starting your prescription drops.
- Severe eye pain or significantly increased redness
- A white spot on the cornea
- Thick, yellow, or green discharge from the eye
- Sudden vision changes or new onset of many floaters
- Swelling of the face or difficulty breathing, which may indicate an allergic reaction
Worsening symptoms that do not improve after starting your drops should always be reported to our team. These could signal an eye infection or another issue that needs separate treatment.
Neither Xiidra nor Restasis should be used while an active eye infection is present. We typically treat any infection first and resume or initiate anti-inflammatory therapy once your eyes have cleared. Patients who are pregnant, breastfeeding, or planning to become pregnant should discuss the limited available safety data with their eye doctor so that any decision to use these medications is made with a full understanding of potential risks and benefits.
Remove your contact lenses before instilling either Xiidra or Restasis, and wait at least fifteen minutes before reinserting them. The ingredients in both medications can interact with contact lens materials. Our optometry team, including Dr. Paul Zerbinopoulos and Dr. Earle Scharff, specializes in specialty contact lenses for patients with dry eye and can help you find a lens strategy that supports healing while maintaining your vision correction needs.
Cost, Insurance, and Practical Considerations
Understanding the financial side of prescription dry eye treatment helps you plan ahead and avoid gaps in therapy. Our staff is experienced in navigating coverage and assistance programs to help make treatment accessible.
Both Xiidra and Restasis are brand-name medications and can carry a significant retail price without insurance. Actual out-of-pocket costs depend on your specific plan, deductible, and copay structure. Generic cyclosporine products are available as alternatives to brand-name Restasis. These generics contain the same active ingredient at the same concentration and can meaningfully reduce costs, though differences in the vehicle formulation may affect comfort for some patients. A generic equivalent for Xiidra is not currently available.
Many insurance plans cover these medications but require prior authorization before approving the prescription. This process involves our office submitting documentation of your diagnosis and may require showing that you tried other treatments first. Approval can take several days to a few weeks, and some plans prefer one medication over the other based on their formulary. Our staff can check your coverage and manage the prior authorization process on your behalf.
Both manufacturers offer copay savings cards and patient assistance programs that can reduce your cost. Copay cards are typically available to patients with commercial insurance and do not apply to government-funded insurance programs. If you are uninsured or underinsured, patient assistance programs may provide free or discounted medication based on income eligibility.
- Manufacturer copay cards for commercially insured patients
- Patient assistance programs for those without adequate coverage
- Pharmacy discount programs that may offer lower prices on generic cyclosporine
- Our staff can guide you through available options and help you apply
Both Xiidra and Restasis are dosed twice daily, approximately twelve hours apart, with one drop in each eye in the morning and one drop in each eye in the evening. Consistency is essential for both medications to work, so building your drops into an existing routine such as brushing your teeth helps you stay on schedule. Xiidra is supplied as single-use preservative-free vials. Cyclosporine products may come as single-use vials or as a preservative-free multidose bottle depending on the brand or generic selected.
- If you use more than one eye medication, wait at least five to ten minutes between drops to prevent washout
- Invert cyclosporine vials several times before use to ensure the emulsion is uniform
- Use punctal occlusion after each dose by pressing gently on the inner corner of your closed eyelids for one to two minutes
- Use each single-use vial for both eyes immediately and then discard it
- Avoid letting the tip of the vial or bottle touch your eye or eyelid
- Do not drive or operate machinery until any temporary blurring clears
Managing and Personalizing Your Dry Eye Treatment
Our approach to dry eye care is collaborative and individualized. We consider your full clinical picture, your lifestyle, and your goals to build a plan that works for you over the long term.
When recommending Xiidra or Restasis, we weigh the severity of your dry eye, your specific symptoms, your insurance coverage, your tolerance for potential side effects, and how quickly you need relief. Dr. Whitney Catanio and our broader dry eye team coordinate comprehensive evaluations to match the right therapy to each patient's needs. We will discuss these factors together and make a personalized recommendation before you leave your appointment.
If you complete an adequate trial of one medication without sufficient improvement, switching to the other is safe and straightforward. We generally ask patients to use the first medication for at least three months before deciding it is not working, though we may act sooner if you experience side effects you cannot tolerate. When switching, you can typically stop one medication and begin the other without a waiting period. We will give you clear instructions based on your specific situation.
Prescription drops often work best as part of a broader dry eye management plan. Depending on your diagnosis, we may recommend additional therapies to complement your medication and improve your overall comfort. Our team is equipped to provide coordinated care, including collaboration with our oculoplastic surgeons when eyelid anatomy is contributing to your dry eye.
- Preservative-free artificial tears for breakthrough dryness between doses
- Warm compresses and eyelid hygiene for meibomian gland dysfunction
- Omega-3 supplements, which may benefit patients with oil gland dysfunction, though evidence is mixed
- Environmental adjustments such as humidifiers or moisture-retaining eyewear
- Specialty contact lenses, including scleral and moisture-retention lenses, for patients with severe ocular surface disease
Dr. Earle Scharff, who brings decades of experience in specialty lens fitting and ocular surface therapies, and Dr. Paul Zerbinopoulos, who specializes in scleral and moisture-retention lenses, are available to help patients whose dry eye significantly affects their vision or contact lens tolerance.
We will schedule a follow-up after you have been using your prescription drops for several weeks to months. At that visit, we will reexamine your eyes, recheck tear production, and review your symptom changes to assess how well the medication is working. Honest feedback about your experience, including any side effects and whether your comfort has improved, helps us refine your plan and decide whether to continue, adjust, or add to your current treatment.
Reach out to our office if you develop severe side effects, signs of an eye infection, or symptoms that are worsening rather than improving after starting your drops. We also want to hear from you if you are struggling to use the drops correctly, if cost is preventing you from filling your prescription, or if you have any questions about your treatment plan. We are here to support you throughout the process and make adjustments whenever needed.
Frequently Asked Questions
Here are answers to questions we hear most often from patients who are considering or already using Xiidra or Restasis. These are intended to add practical guidance beyond what is covered above.
Using both medications together is not a standard first-line approach because evidence for added benefit is limited. In select situations where dry eye disease is severe and difficult to control, an eye doctor may consider combination therapy on a case-by-case basis with close follow-up. If more than one prescription drop is prescribed, each dose should be separated by at least five to ten minutes to prevent one medication from washing out the other.
Most patients need to continue using Xiidra or Restasis long term because chronic dry eye is an ongoing condition. Stopping the medication typically allows inflammation to return, along with symptoms. Some patients who achieve very stable control may eventually be able to reduce their dosing frequency or take a supervised break, but this decision is made on an individual basis and should not be done without guidance from your eye doctor.
If you have completed adequate trials of both Xiidra and Restasis without sufficient improvement, or if you cannot tolerate either one, there are additional options we can explore. The right next step depends on the specific type and severity of your dry eye, and our team will work with you to find an approach that provides real relief.
- Cyclosporine 0.09% or 0.1% formulations for patients who need an alternative cyclosporine concentration
- Loteprednol 0.25% ophthalmic suspension for short-term management of dry eye flares, typically up to two weeks
- Varenicline nasal spray to stimulate natural tear production through the nasal-lacrimal reflex
- Perfluorohexyloctane drops for evaporative dry eye related to meibomian gland dysfunction
- Thermal pulsation or in-office meibomian gland expression procedures
- Autologous serum or platelet-rich plasma tears for advanced ocular surface disease
Yes, and for most patients we actively encourage it. Prescription drops address the underlying inflammation and take weeks to months to show their full effect. Preservative-free artificial tears provide immediate lubrication to help you stay comfortable in the meantime. To prevent the prescription drop from being washed out before it can work, wait at least fifteen minutes after instilling your Xiidra or Restasis before using artificial tears.
Yes, the context matters significantly. LASIK can temporarily reduce corneal sensation and worsen dry eye during healing, so we evaluate and treat dry eye before and after refractive surgery. For cataract surgery, an unhealthy ocular surface can lead to inaccurate measurements and affect your outcome, which is why we prioritize ocular surface optimization as part of surgical preparation. Dr. Christopher Newton and our refractive and cataract surgery team work closely with our dry eye specialists to coordinate care for these patients.
