The display and use of drug information on this site is subject to express terms of use. By continuing to view the drug information, you agree to abide by such terms of use.

GENERIC NAME: LATANOPROST – OPHTHALMIC SOLUTION (lay-TAN-oh-prost)

BRAND NAME(S): Xalatan

USES: Latanoprost is used to treat high pressure inside the eye due to glaucoma (open angle type) or other eye diseases (e.g., ocular hypertension). It is similar to a natural chemical in the body (prostaglandin) and works by regulating the flow of fluid within the eye which results in lower pressure. Lowering high pressure inside the eye helps to prevent blindness.

HOW TO USE: Apply this medication in the affected eye(s) usually once daily in the evening, or as directed by your doctor. Do not use this medication more frequently than prescribed; using more can decrease effectiveness. To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface. The preservative in this product may be absorbed by contact lenses. If you wear contact lenses, remove them before using this medication and keep them out of your eyes for at least 15 minutes after applying latanoprost. Tilt your head back, look upward and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and apply the prescribed number of drops. Look downward and gently close your eye for 1 to 2 minutes. Place one finger at the inside corner of your eye near the nose and apply gentle pressure. This will prevent the medication from draining out. Try not to blink and do not rub your eye. Do not rinse the dropper. Replace the dropper cap after each use. Use this medication regularly to get the most benefit from it. Remember to use it at the same time each day. It is important to continue using latanoprost even if you feel well. Most people with glaucoma or high pressure in the eye do not feel sick. If you are using another kind of eye medication (e.g., drops or ointments), wait at least 5 minutes before applying other products. Use eye drops before eye ointments to allow the eye drops to enter the eye.

SIDE EFFECTS: Blurred vision, burning/stinging/itching/redness of the eye, feeling as if something is in the eye, changes in eyelash number/color/length/thickness, eyelid changes/skin darkening, dry eye, lid crusting/discomfort, increased sensitivity to light, flu-like symptoms, or muscle/joint pain may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. This medication may slowly (over months to years) cause brown discoloration of the colored portion of the eye (iris). If you are using latanoprost in only one eye, only that iris may change color. This color change may be permanent but the long-term effects are uncertain. Notify your doctor if this occurs and schedule regular eye exams to monitor it. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor immediately if any of these unlikely but serious side effects occur: eye pain, suspected eye infection (unusual redness or swelling of eyes), chest pain. Tell your doctor immediately if any of these highly unlikely but very serious side effects occur: rapid vision changes (e.g., loss of vision). A serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, severe itching/swelling (especially of the face/tongue/throat), dizziness, trouble breathing. This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
