Restasis (cyclosporine) is a prescription drug that’s used to treat chronic dry eye in adults and some children. Restasis can cause side effects that range from mild to serious. Examples include a burning sensation in the eye, blurred vision, and eye pain.
For more information about Restasis, including details about its uses, see this Restasis overview.
Restasis also comes in a version called Restasis MultiDose. While Restasis comes in single-dose vials, Restasis MultiDose comes in a bottle containing multiple doses. Otherwise, these drugs are the same. The side effects of Restasis discussed in this article also apply to Restasis MultiDose.

Get answers to some frequently asked questions about side effects of Restasis.
Does Restasis cause side effects related to eyelashes or eyelash growth?
No, Restasis isn’t known to cause side effects that affect eyelashes or eyelash growth.
One
Talk with your doctor if you’re concerned about side effects Restasis may cause, including effects on your eyelashes.
Can Restasis cause hair loss, high blood pressure, or headache?
No, Restasis is not known to cause hair loss, high blood pressure, or headache. Because Restasis is an eye drop, very little of the drug reaches the rest of your body. So side effects such as hair loss and headache aren’t expected with this medication. These side effects weren’t reported among people using Restasis in studies.
However, hair loss, high blood pressure, and headache are all side effects that have been reported in people taking cyclosporine by mouth. Cyclosporine is the active ingredient in Restasis. (An active ingredient is what makes a drug work.)
Are there long-term side effects of Restasis?
No, Restasis isn’t known to cause long-term side effects. See other sections of this article to learn about mild and serious side effects Restasis may cause. You can also talk with your doctor or pharmacist to learn more.
Learn more about some of the side effects Restasis may cause.
Blurry vision
Treatment with Restasis may cause blurry vision as a side effect. While this side effect was more common than some others, most people who used Restasis in studies didn’t report blurry vision.
What might help
Blurry vision may occur right after you use Restasis but should go away on its own after a couple of minutes. Your doctor can recommend the best treatment for relieving your symptoms.
But if you experience blurry vision that doesn’t go away, talk with your doctor. They’ll likely recommend you stop using Restasis. They can discuss other treatments for your chronic dry eye with you.
Burning in your eye
Burning in your eye is a side effect Restasis may cause. In fact, this was the most common side effect reported by people who used Restasis in studies. This side effect usually goes away on its own after a few minutes.
What might help
To help prevent burning in your eye, avoid touching the tip of the Restasis dropper against your eye. You should also avoid letting the tip touch any other surfaces. This could contaminate the dropper with germs and may cause a burning sensation in your eye when you use Restasis.
You should also be sure to always wash your hands before using Restasis.
If you have burning in your eye that doesn’t go away while using this medication, contact your doctor. They can recommend the best way to treat your symptoms, which may include stopping treatment with Restasis.
Feeling like something is in your eye
After using Restasis, you may experience a feeling like something is in your eye. But this side effect didn’t happen in most people who used the drug in studies.
What might help
You can help prevent this side effect by not letting the tip of the Restasis dropper touch your eye or any other surface.
If you feel like something is in your eye and the feeling doesn’t go away, contact your doctor. They can recommend the best treatment for your symptoms. This may include stopping treatment with Restasis and trying something different for your dry eye.
Eye pain
After using Restasis, you may develop eye pain as a side effect. Although this was a more commonly reported side effect of Restasis, most people who used the drug in studies didn’t experience eye pain.
What might help
You can help prevent eye pain from Restasis by not letting the tip of the dropper touch your eye or any other surface.
If you experience eye pain that doesn’t go away while using Restasis, contact your doctor. They can recommend the best way to treat your symptoms. This may include stopping treatment with Restasis and exploring other treatments for dry eye instead.
Allergic reaction
Like most drugs, Restasis can cause an allergic reaction in some people. This side effect wasn’t reported in studies, but it has been reported since the drug became available.
Symptoms may be mild to serious and can include:
What might help
If you have mild symptoms of an allergic reaction, such as a mild rash, call your doctor right away. They may suggest a treatment to manage your symptoms. Examples include:
- an antihistamine you take by mouth, such as Benadryl (diphenhydramine)
- a product you apply to your skin, such as hydrocortisone cream
If your doctor confirms you’ve had a mild allergic reaction to Restasis, they’ll decide whether you should continue using it.
If you have symptoms of a severe allergic reaction, such as swelling or trouble breathing, call 911 or your local emergency number right away. These symptoms could be life threatening and require immediate medical care.
If your doctor confirms you’ve had a serious allergic reaction to Restasis, they may have you switch to a different treatment.
Keeping track of side effectsDuring your Restasis treatment, consider taking notes on any side effects you’re having. You can then share this information with your doctor. This is especially helpful when you first start taking new drugs or using a combination of treatments.
Your side effect notes can include things such as:
- what dose of the drug you were taking when you had the side effect
- how soon you had the side effect after starting that dose
- what your symptoms were
- how it affected your daily activities
- what other medications you were taking
- any other information you feel is important
Keeping notes and sharing them with your doctor will help them learn more about how Restasis affects you. They can then use this information to adjust your treatment plan if needed.
Restasis may not be right for you if you have certain medical conditions. (This is known as a drug-condition interaction.) Other factors may also affect whether Restasis is a good treatment option for you. Talk with your doctor about your health history before starting Restasis. Factors to consider include those described here.
Contact lenses: You should not give yourself a dose of Restasis while wearing contact lenses. If you wear contacts, your doctor will recommend removing them before you apply the eye drops. You should wait at least 15 minutes before re-inserting your contacts after a Restasis dose.
Allergic reaction: If you’ve had an allergic reaction to Restasis or any of its ingredients, your doctor will likely not prescribe it for you. Ask them about other treatments that might be better options.
Alcohol and Restasis
There’s no known interaction between Restasis and alcohol.
Talk with your doctor if you have questions or concerns about consuming alcohol while you’re using this medication.
Pregnancy and breastfeeding while using Restasis
It’s believed that Restasis is safe to use while pregnant. The drug is an eye drop that isn’t expected to be absorbed by the rest of your body. Still, if you are pregnant or planning to become pregnant, be sure to review all medications you take with your doctor and pharmacist. They can offer advice on the safest treatments for your condition during pregnancy.
It’s not known whether Restasis passes into breast milk. However, since the drug is applied to the surface of the eye, the amount that might enter the bloodstream and then pass into breast milk is probably minimal. So it’s unlikely to cause significant side effects in a child who is breastfeeding.
Talk with your doctor if you are breastfeeding or planning to breastfeed while using Restasis.
Like most medications, Restasis can cause side effects. Burning in your eye is the most common mild side effect, and other mild side effects are rare. Serious side effects weren’t reported in studies of the drug. However, there were reports of Restasis causing serious allergic reaction after the drug became available.
If you’d like to learn more about Restasis, including possible side effects the drug may cause, talk with your doctor or pharmacist. Examples of questions you may want to ask include:
- Will my risk of side effects from Restasis decrease over time?
- If I have side effects from Restasis, what are my options? Can I try a lower dosage?
- How do side effects caused by Restasis compare with other drugs for treating my condition?
