Latanoprost is a prostaglandin analogue medicine that treats high pressure inside the eye and helps treat glaucoma.
High pressure is usually caused by fluid building up in the front part of the eye, which can then increase pressure inside the eye.
If not treated, high pressure can damage your optic nerve and cause vision loss or blindness.
Latanoprost is available on prescription only.
It comes as eye drops, either in eye drop bottles with a preservative in, or in single-dose droppers that are preservative-free.
You may sometimes be prescribed eye drops containing both latanoprost and timolol (a beta blocker).
