Uses

What is Latanoprost used for?

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 should I take Latanoprost?

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 in order 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.

How do I store Latanoprost?

Store opened bottles at room temperature. Throw away any part not used after 6 weeks. To prevent drug damage, you should not store Latanoprost in the bathroom or the freezer.
