1. What Latanoprost Pfizer is and what it is used for
Latanoprost Pfizer belongs to a group of medicines known as prostaglandin
analogues. It works by increasing the natural outflow of fluid from inside the
eye into the bloodstream.
Latanoprost Pfizer is used to treat conditions known as open angle
glaucoma and ocular hypertension in adults. Both of these conditions are
linked with an increase in the pressure within your eye, eventually affecting
your eye sight.
Latanoprost Pfizer is also used to treat increased eye pressure and glaucoma
in all ages of children and babies.

mixed-colour eyes (blue-brown, grey-brown, yellow-brown or
green-brown) you are more likely to see this change than if you have eyes
of one colour (blue, grey, green or brown eyes). Any changes in your eye
colour may take years to develop although it is normally seen within
8 months of treatment. The colour change may be permanent and may be
more noticeable if you use Latanoprost Pfizer in only one eye. There
appears to be no problems associated with the change in eye colour. The
eye colour change does not continue after Latanoprost Pfizer treatment is

sensation of a foreign body in the eye). If you experience eye irritation

stopping this medicine, talk to your doctor, pharmacist or nurse promptly
(within a week). You may need your treatment to be reviewed to ensure
you keep receiving appropriate treatment for your condition.
• A gradual change to eyelashes of the treated eye and the fine hairs around
the treated eye, seen mostly in people of Japanese origin. These changes
involve an increase of the colour (darkening), length, thickness and number
of your eye lashes.

• Irritation or disruption to the surface of the eye, eyelid inflammation
(blepharitis), eye pain, light sensitivity (photophobia), conjunctivitis.

of the eye, fluid filled area within the coloured part of the eye (iris cyst).

Side effects seen more often in children compared to adults are: runny itchy
nose and fever.
