How does this medication work? What will it do for me?
Lodoxamide eye drops belong to the class of medications called mast cell stabilizers. They are used to help relieve eye symptoms such as itching, tearing, and redness caused by allergic reactions, severe eye irritation (vernal keratoconjunctivitis), and certain eye irritations caused by wearing contact lenses. Relief of symptoms usually occurs within several days of starting the medication, but may take up to 4 weeks to get the maximum effect.
Cells called mast cells release histamine and other chemicals in the body that cause inflammation and irritation. These chemicals are responsible for allergy symptoms such as itchy, watery eyes as well as redness, irritation, and the feeling of “something in the eye.” Lodoxamide works by blocking their release.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Blurred vision: As with other medications that are put directly into the eye, lodoxamide may cause temporarily blurred vision. It is advisable to avoid driving or other activities that require clear vision until your vision has cleared after using the eye drops.
Contact lenses: This medication contains benzalkonium chloride as a preservative. This chemical can build up on contact lenses, making them uncomfortable and occasionally causing damage to the eye. It may also cause discoloration of soft contact lenses. Remove your contact lenses before putting lodoxamide eye drops in your eyes. Do not put the contact lenses back in for at least 15 minutes after using these eye drops.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while using this medication, contact your doctor immediately.
Breast-feeding: It is not known if lodoxamide passes into breast milk. If you are a breast-feeding mother and are using this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using lodoxamide eye drops have not been established for children under 4 years old.
What other drugs could interact with this medication?
Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,

- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
