Prostaglandin analogs have turquoise bottle caps. If you need to use more than one type of eyedrop, you may need to take each medicine in a certain order. You can use the color of the bottle cap to help you keep track of each type of eyedrop.
If you are using more than one type of eyedrop, wait 5 minutes between the different eyedrop medicines.
Prostaglandin analogs reduce pressure
inside the eye (intraocular pressure, or IOP) by increasing the
removal of fluid (aqueous humor) from the eye.

reduce intraocular pressure in people who have glaucoma or high intraocular pressure
(ocular hypertension). They can be used alone or in combination with other

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
The colored part of your eye (iris) may change color if you take prostaglandin analogs. It's most likely to occur if you have hazel eyes. These medicines may also cause the eyelid to darken and eyelashes to grow longer. These changes could last forever. They would affect only the eye that's being treated.
Latanoprost may cause your eyes to become more sensitive to light. You may want to avoid bright light or wear sunglasses.
Prostaglandin analogs should be
used with caution by people who have infections or inflammation in the eye, who have had cataract surgery or other
problems with the lens of the eye, or who are at risk for swelling in the
macula at the back of the eye.
People who wear contact lenses
need to take their contacts out before putting these eyedrops into their eyes.
The contacts can be reinserted 15 minutes after using the eyedrops.
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
