How do you take Latanoprost?

Put one drop into the affected eye(s) once daily, preferably in the evening. Do not use it more than once a day, as using it more often can actually make it less effective. After putting the drop in, gently press the corner of your eye near your nose for about one minute to stop the medicine from draining into your body. If you wear contact lenses, remove them before applying and wait at least 15 minutes before putting them back in.

Redness of the eye, gradual change in eye colour (the brown part of the eye may become darker over time), feeling like something is in your eye, itchy or stinging eyes, darkening and thickening of the eyelashes

Who should not take Latanoprost?

People who are allergic to latanoprost or any ingredient in the eye drop. People who wear contact lenses should use with caution. People who have had eye surgery recently or have eye infections should consult their doctor first. People with asthma should inform their doctor before use.

What is this drug?

Latanoprost is an eye drop that lowers pressure inside the eye by helping fluid drain out more easily. It belongs to a group of medicines called prostaglandin analogues that mimic natural substances in the body to improve fluid flow from the eye.

How it works

Binds to prostaglandin F (FP) receptors in the eye, increasing uveoscleral outflow of aqueous humour and thereby reducing intraocular pressure.

What is it used for?

High eye pressure (glaucoma), raised pressure inside the eye (ocular hypertension) that can lead to gradual loss of sight if untreated

What to watch out for

Buy only from reputable pharmacies, as eye drops from roadside sellers or unregistered shops may be fake or contaminated, which can damage your eyes. Do not share your eye drops with anyone else, even if they have similar symptoms. The colour change in your eye (iris) may be permanent, so discuss this with your doctor before starting treatment.

Common Side Effects

Redness of the eye
gradual change in eye colour (the brown part of the eye may become darker over time)
feeling like something is in your eye
itchy or stinging eyes
darkening and thickening of the eyelashes

Serious Side Effects

Sudden eye pain with headache
nausea
or blurred vision
which could mean a serious eye problem. Swelling around the eye or severe allergic reaction such as rash and difficulty breathing. Any sudden change in vision requires immediate medical attention from a doctor.

Drug Interactions

If you use other eye drops, wait at least 5 minutes between each one so the medicines don't wash each other out. Using latanoprost together with other prostaglandin-type eye drops (like bimatoprost or travoprost) can increase side effects and reduce effectiveness. Tell your doctor about all medicines you are using, including herbal remedies.
