Cequa works by targeting the underlying inflammation that often occurs in dry eye disease. The active ingredient, cyclosporine A, inhibits the activation of T-cells, which are part of the immune system. T-cells play a key role in inflammation, and their activation in the eyes contributes to the symptoms of dry eye disease, such as discomfort, irritation, and redness.
By reducing T-cell activation, Cequa helps decrease inflammation in the tear glands (lacrimal glands), improving their ability to produce tears. In turn, this helps to relieve dryness, discomfort, and other symptoms associated with dry eye disease. It is not a quick solution but works over time to help manage the condition, making it suitable for long-term use in appropriate patients.
Cequa is generally well tolerated, but like all medications, it can cause side effects. Some of the most common side effects include:
- Eye Irritation: This is one of the most common side effects, causing a feeling of stinging or burning in the eyes after application.
- Redness of the Eyes: Some people may experience mild redness or discomfort in the eyes.
- Temporary Blurry Vision: Some users report temporary blurry vision immediately after applying the drops, which should resolve quickly.
- Foreign Body Sensation: A feeling that something is in the eye, or a scratchy sensation, can occur after using Cequa.
- Other Reactions: Rarely, people may experience more serious side effects, such as an allergic reaction, which could include symptoms like swelling, itching, or redness of the eyelids.
If you experience any severe side effects, such as eye swelling, difficulty breathing, or severe redness or discomfort, you should contact your doctor immediately.
Cequa should be used with caution under the following circumstances:
- Eye Infections: Cequa should not be used to treat eye infections such as bacterial conjunctivitis. If you have an active eye infection, your doctor will treat it before prescribing Cequa.
- Pregnancy and Breastfeeding: There are no adequate studies on the use of Cequa during pregnancy. It is classified as a Category C medication, which means it should only be used if the potential benefit justifies the potential risk to the fetus. Cequa is also excreted in breast milk, so it should be used cautiously in breastfeeding mothers.
- Other Eye Conditions: If you have other eye conditions (such as glaucoma, cataracts, or ocular herpes), talk to your doctor before using Cequa, as these conditions may require special considerations or alternative treatments.
There are no significant known interactions between Cequa and other medications when used as directed for dry eyes. However, it is always essential to inform your doctor if you are using other eye drops, especially those containing steroids or other immunosuppressive agents. You should also inform your doctor about any other medications you are taking, including oral medications, to avoid potential interactions.
The recommended dosage for Cequa is:
- One drop in each affected eye twice daily (about 12 hours apart).
It is essential to follow your doctor’s instructions regarding dosage and administration. Do not exceed the recommended dose, as overuse may increase the risk of side effects.
Cequa is a prescription-only medication, which means it must be prescribed by a healthcare provider. If you suffer from dry eye disease and are considering Cequa, consult your doctor to see if it is appropriate for your condition. They will assess your symptoms and medical history and determine if Cequa is the right treatment option for you.
