Contents of the package leaflet
Xiop contains latanoprost and belongs to a group of medicines known as prostaglandin analogues. It works by increasing the natural flow of fluid from the inside of the eye into the bloodstream.
Xiop is used to treat conditions known as open-angle glaucoma and ocular hypertension. Both conditions are related to an increase in pressure inside the eye, which can affect vision.
Xiop is also used to treat increased pressure inside the eye and glaucoma in children and babies of all ages.
Xiop can be used in adult men and women (including elderly patients) and in children from birth to 18 years of age. It has not been investigated in premature infants (less than 36 weeks of gestation).
Do not use Xiop
