Restasis is not available over the counter. It is classified as a prescription-only drug by the FDA, meaning you need a doctor’s authorization to purchase it. This applies to both the brand-name product and its generic versions, which contain the same active ingredient, cyclosporine ophthalmic emulsion 0.05%.
Why Restasis Requires a Prescription
Restasis works differently from the lubricating eye drops you can grab off a pharmacy shelf. It contains cyclosporine, an immunomodulator that reduces inflammation on the surface of the eye. This inflammation is what suppresses tear production in people with chronic dry eye disease (known clinically as keratoconjunctivitis sicca). By calming that inflammatory response, Restasis helps your eyes produce more of their own tears over time.
That mechanism is the key reason it stays behind the pharmacy counter. Cyclosporine affects your immune system, even when applied topically to the eye. The most common side effect in clinical trials was burning in the eye, reported by 17% of patients. Between 1% and 5% experienced redness, eye pain, stinging, discharge, or temporary blurred vision. Rare but serious allergic reactions have also been reported after the drug reached the market, including significant swelling of the face, tongue, or throat. These risks require a clinician to evaluate whether the drug is appropriate for you and to monitor how you respond to it.
Restasis is also contraindicated for anyone with a known or suspected allergy to any of its ingredients, and it should not be used while wearing contact lenses. If you wear contacts, they need to come out before each dose and stay out for at least 15 minutes afterward.
How Restasis Differs From OTC Eye Drops
Over-the-counter artificial tears are lubricants. They coat the surface of your eye with moisture, providing temporary relief from dryness and irritation. They don’t change anything about how your eye functions. Once the drop dries or drains away, the relief fades.
Restasis treats an underlying cause of dry eye rather than just masking the symptom. If your dry eye is driven by chronic inflammation that’s suppressing tear production, artificial tears won’t address that root problem no matter how often you use them. Restasis can, but it takes time. Most people don’t notice a significant improvement for several weeks, and the drops are used twice daily on an ongoing basis. This is another reason a prescription is involved: the treatment requires a correct diagnosis and a commitment to a regimen that a doctor helps manage.
Generic Options and Cost
Multiple generic versions of cyclosporine ophthalmic emulsion 0.05% are now FDA-approved and available, produced by manufacturers including Mylan, Teva, and Amneal, among others. These generics contain the same active ingredient at the same concentration as brand-name Restasis, but they still require a prescription.
The retail price of brand-name Restasis is around $59 per fill, though this can vary depending on the quantity prescribed and your pharmacy. Generic versions start around $265 for a 30-unit supply, though discount programs and insurance coverage can significantly change what you actually pay. The pricing landscape for generics can be counterintuitive since brand-name manufacturer coupons sometimes make the original cheaper than the generic at the register. It’s worth comparing both options with your pharmacist.
What to Do if You Think You Need Restasis
If over-the-counter artificial tears aren’t managing your dry eye symptoms, that’s a signal your condition may involve the kind of chronic inflammation Restasis is designed to treat. An eye doctor can evaluate whether your reduced tear production is inflammation-driven and whether cyclosporine is the right fit. They’ll also rule out other causes of dry eye that would call for different treatment entirely.
In the meantime, preservative-free artificial tears are the best OTC option for symptom relief. Drops with preservatives can irritate already-sensitive eyes when used frequently, so preservative-free formulations are generally a better choice for people using them multiple times a day.
