Q: What is Lifitegrast used for?

Lifitegrast is used to treat dry eye disease .

Q: How does Lifitegrast work?

Mechanism of Action Lifitegrast belongs to a class of drugs known as lymphocyte function-associated antigen-1 (LFA-1) antagonists. It works by targeting the underlying inflammation that often contributes to dry eye symptoms. In dry eye disease, the surface of the eye can become inflamed due to the activity of certain white blood cells. Lifitegrast works by blocking specific protein interactions that drive this inflammatory process. The process involves the following steps: Binding to LFA-1: Lifitegrast binds to a protein called lymphocyte function-associated antigen-1 (LFA-1) found on the surface of white blood cells (leukocytes). Blocking ICAM-1 interaction: By binding to LFA-1, the medication prevents it from interacting with another protein called intercellular adhesion molecule-1 (ICAM-1). ICAM-1 is often found in high amounts on the surface of the eye in individuals with dry eye disease. Reducing inflammation: When these two proteins are prevented from connecting, the inflammatory response on the surface of the eye is decreased. By reducing this inflammation, lifitegrast helps alleviate the irritation and discomfort associated with dry eye and may help improve the eye's ability to maintain a healthy tear film.

Q: What is the dosage of Lifitegrast and how do I take it?

How to Use Lifitegrast is typically applied as one drop into each eye twice a day, approximately 12 hours apart. This medication is provided in single-use containers. To apply the drops correctly, follow these general steps: Wash your hands thoroughly before handling the medication. If you wear contact lenses, remove them before using the drops. You should wait at least 15 minutes after application before putting your contact lenses back in. Tear off one single-use container from the strip and shake it so the liquid moves to the bottom. Twist off the tab to open the container. Tilt your head back and pull down the lower eyelid to create a small pocket. Hold the container over the eye and squeeze one drop into the pocket. Do not let the tip of the container touch your eye, eyelid, fingers, or any other surface. Repeat the process for the other eye if instructed. Each single-use container holds enough medicine for both eyes. Discard the container and any remaining liquid immediately after one use. Do not save opened containers for later doses. Missed Dose If you miss a dose, use it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and resume your regular schedule. Do not use extra medicine to make up for a missed application.

Q: Is Lifitegrast safe during pregnancy and breastfeeding?

Pregnancy It is not known if lifitegrast will harm an unborn baby. There is a lack of adequate data from human studies to confirm its safety during pregnancy. Animal studies using high doses of the medication did not show evidence of harm to the developing fetus. Because the drug is applied topically to the eye, only a small amount enters the bloodstream, which may reduce potential exposure during pregnancy. Breastfeeding There is no information available on whether lifitegrast is present in human breast milk or how it might affect a breastfed infant. While the amount of medication absorbed into the body is low, individuals who are breastfeeding should consult with a healthcare professional to weigh the potential benefits against any unknown risks.

Q: What forms and strengths does Lifitegrast come in?

Available Forms Lifitegrast is supplied as an ophthalmic solution, which is a liquid intended for use as eye drops. This medication is typically packaged in single-use containers. Each container holds enough liquid to treat both eyes one time. Strengths This medication is available in the following strength: Ophthalmic solution: 5% The single-use containers are usually provided in foil pouches to protect the medication from light. Once a container is opened, it should be used immediately and then discarded, even if there is liquid remaining.
