Restasis can feel like a doubleedged sword: it often eases that relentless dryeye grind, but many users notice a twinge of burning, redness, or even more serious eye changes. Below you'll get the straightup rundown of the most common Restasis side effects, how to soothe them, and the exact moments you should pick up the phone and call your eye doctor.
Think of this guide as a friendly chat over coffeeno jargon, just honest answers and practical tips so you can stay comfortable while treating chronic dry eye.
What is Restasis
Definition
Restasis (cyclosporine ophthalmic emulsion) is a prescription eyedrop formulated to boost your own tear production. It's designed for people with chronic dryeye disease who haven't found relief from overthecounter lubricants.
How it works
The active ingredient, cyclosporine, quietly calms inflammation on the surface of the eye. By dialing down that inflammation, it lets the tiny glands that line the eyelids produce more of the watery component of tears. Restasis's own site explains the mechanism in plain language, and the FDA's prescribing information backs it up with clinical data.
Who should consider it
If you're over 16, have been diagnosed with moderatetosevere dry eye, and artificial tears just aren't enough, Restasis might be the next step. Some specialists also prescribe it offlabel for certain pediatric cases, but that's always a decision made with an eyecare professional.
Side effects overview
| Category | Frequency (per label) | Typical symptoms | When to worry |
|---|---|---|---|
| Very common (10%) | Burning, eye pain, stinging | Transient irritation right after drop | Usually resolves in minutes |
| Common (110%) | Redness, eyelid erythema, increased tearing, blurred vision | Mild irritation, watery eyes | Persist >1week contact doctor |
| Uncommon (0.11%) | Conjunctival hyperemia, corneal infiltrates, keratitis | Visual changes, discharge | Seek care promptly |
| Rare/Serious (<0.1%) | Hypersensitivity, angioedema, severe allergic reaction | Swelling of eyelid/face, breathing difficulty | Emergency 911 or urgent care |
Very common burning & stinging
The instant "pinch" you feel when the drop lands is usually the vehicle (the liquid that carries the medicine) irritating the surface. It's uncomfortable, but most people find it fades after a few days as the eye adapts.
Common ocular side effects
Redness and a watery eye are classic "hey, something's happening" signals. Blurred vision can be a bit unnervingespecially if you need to drive. If the fog clears after a few minutes, it's probably just the drop mixing with your natural tears.
Less common / serious events
Corneal infiltrates or keratitis are rare but serious. They look like small white spots on the cornea and can make vision hazy. If you notice persistent pain, light sensitivity, or a sudden drop in visual clarity, stop the drops and call your eye doctor right away.
Systemic side effects (rare)
Because the medication is applied locally, systemic issues are uncommon. Still, a few users have reported urinary discomfort or flulike aches. If anything feels "off" beyond your eyes, bring it up with your provider.
Managing side effects
Burning & stinging
Try these simple tricks:
- Close the eye gently for 30seconds after instilling the dropthis gives the medicine a chance to soak in without spattering.
- Use a cool compress (a clean, chilled washcloth) for a minute after dosing.
- Wait at least five minutes before applying any other eye drops or ointments.
If the sting lasts more than two days, reach out to your physician.
Redness & irritation
Complement Restasis with preservativefree artificial tears, but only apply them 15minutes after the prescription drops. This spacing reduces the chance of compounding irritation.
Blurred vision
Schedule your dosing at night if possible, so any temporary blur won't interfere with daytime activities. Refrain from driving until your vision clearsyour safety matters.
Allergic reactions
If you notice swelling around the eye, hives, or any breathing trouble, discontinue the drops immediately and seek emergency care. These signs point to a hypersensitivity that needs rapid attention.
Lifestyle tweaks
Dry environments are the enemy. A humidifier in your bedroom, keeping windows closed on windy days, and taking short breaks from screens can all help. Some folks also find omega3 supplements (fish oil or algaederived) give their tear film a little extra boostMayo Clinic notes the benefit for many dryeye patients.
Proper administration technique
Here's a quick checklist you can print and stick to your mirror:
- Wash hands thoroughly.
- Shake the bottle gently.
- Tilt head back, pull down lower eyelid to create a tiny pocket.
- Hold the bottle upsidedown, squeeze one drop into the pocketno touching the tip to the eye.
- Close eye gently, press the inner corner for 30seconds to prevent drainage into the nose.
Following these steps reduces contamination risk and can lessen that immediate burn.
Restasis dosage
Standard dosing
Most adults use one drop per eye twice daily, spaced about 12hours apart. Consistency is key; skipping doses can interrupt the therapeutic effect.
Special populations
Children under 16 may be prescribed a lower dose, but that decision rests entirely with the ophthalmologist. Elderly patients don't need a different dosage, though they might be more sensitive to the initial sting.
Multidose vs. singleuse vials
Restasis comes in a multidose bottle (store at 28C) and a singleuse vial (room temperature). The multidose version can become contaminated if the tip touches anything, so handle it with clean hands. The singleuse vial eliminates that risk but can be pricier.
When to seek help
Keep this quickalert checklist handy:
- Burning that lasts more than three days.
- Sudden loss of vision, new floaters, or halos.
- Swelling of eyelid or face, especially around the eyes.
- Difficulty breathing or feeling faint.
- Any systemic symptoms like fever, urinary pain, or severe headache.
If you tick any of those boxes, stop the drops and contact your eye doctoror head to the ER for severe allergic signs.
Comparison with alternatives
Efficacy
Clinical trials show Restasis improves tear production by roughly 23% over baseline. Newer options like Xiidra (lifitegrast) report a 56% increase, but individual response varies.
Sideeffect profile
| Medication | Common side effects | Rare but serious |
|---|---|---|
| Restasis | Burning, stinging, redness | Corneal infiltrates, severe allergy |
| Xiidra | Eye irritation, dysgeusia (bad taste) | Severe allergic reaction (rare) |
| Cequa (nanomicellar cyclosporine) | Blurred vision, eye pain | Corneal ulcer (very rare) |
Cost & insurance
Restasis typically runs $350$400 for a 30day supply without insurance. Many pharmacy benefit managers cover it under specialty drug tiers, but outofpocket costs can still be high. Xiidra and Cequa fall into a similar price bracket. Checking with your insurer's formulary or exploring manufacturer coupons can make a big difference.
