1. What is Latanest and what is it used for

Latanest belongs to a group of medicines known as prostaglandin analogues. It works by increasing the natural outflow of fluid from the eye into the bloodstream.

Latanest is used to treat conditions known as open-angle glaucoma and ocular hypertensionin adults. Both of these conditions are linked to an increase in pressure within the eye, which can lead to problems with your sight.

Latanest is also used to treat increased pressure in the eye and glaucoma in babies and children of all ages.

Latanest can be used in adult men and women (including the elderly) and in children from birth to 18 years of age. Latanest has not been studied in premature infants (less than 36 weeks gestation).

Latanest eye drops, solution is a sterile solution that does not contain preservatives.

Instructions for use

1a 1b	Take the bottle (figure 1a)out of the carton and write the date you opened it on the carton and on the bottle in the space provided. Take the medicine and a mirror. Wash your hands. Remove the cap (figure 1b).
2	Hold the bottle upside down with your thumb on the top of the bottle and your other fingers on the bottom of the bottle. Before the first use, pump the bottle repeatedly, about 10 times, until the first drop appears (figure 2).
3	Tilt your head or your child's head back. Pull the lower eyelid down with a clean finger, until there is a 'pocket' between the eyelid and the eye. The drop will go in here (figure 3). Bring the tip of the bottle close to the eye. Use a mirror if it helps.
4	Do not touch the eye or eyelid, the surrounding areas or other surfaces with the dropper.It could infect the drops. Gently squeeze the base of the bottle to release one drop of medicine (figure 4). If a drop does not enter the eye, try again.
5	After using the medicine, press the corner of your eye, near your nose, for 1 minute (figure 5). This helps prevent the medicine from getting into the rest of your body.
	If you use the drops in both eyes, repeat the same steps for the other eye. Close the bottle cap tightly after use. Use one bottle of medicine at a time. Do not open the cap until you need to use the bottle. 2.5 ml: You must discard the bottle after 4 weeks of first opening, to prevent infections, and use a new bottle. 5 ml: You must discard the bottle after 8 weeks of first opening, to prevent infections, and use a new bottle.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

The following side effects have been seen with the use of eye drops containing the active substance latanoprost:

Very common side effects(may affect more than 1 in 10 people):

Gradual change in eye color by increasing the amount of brown pigment in the colored part of the eye known as the iris. If you have mixed-color eyes (blue-brown, grey-brown, yellow-brown or green-brown) you are more likely to experience this change than if your eyes are a single color (blue, grey, green or brown). The change in eye color takes years to develop, although it can usually be seen after 8 months of treatment. The change in eye color may be permanent and may be more noticeable if Latanest is used in one eye only. The change in eye color does not seem to be associated with any problems. The change in eye color does not progress once Latanest treatment is stopped.
Redness of the eye.
Ocular irritation (feeling of burning, feeling of grit in the eye, itching, stinging and feeling of something in the eye). If you experience severe ocular irritation that makes your eyes water excessively, or makes you consider stopping treatment, contact your doctor, pharmacist, or nurse as soon as possible (within a week). You may need to have your treatment reviewed to ensure you are receiving the right treatment for your condition.
Gradual change in the eyelashes of the treated eye and the fine hair around the treated eye, usually seen in patients of Japanese origin. These changes include an increase in color (darkening), length, thickness and number of eyelashes.
