Latanoprost (Ophthalmic route)
Uses of This Medicine:
Latanoprost is used to treat certain kinds of glaucoma. It is also used to treat a condition called hypertension of the eye. Latanoprost appears to work by increasing the outflow of fluid from the eye. This lowers the pressure in the eye.
This medicine is available only with your doctor's prescription.
Before Using This Medicine:
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of latanoprost in children with use in other age groups.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of latanoprost in the elderly with use in other age groups, this medicine has been used mostly in elderly patients and is not expected to cause different side effects or problems in older people than it does in younger adults.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Other medical problems—
The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:
Proper Use of This Medicine:
Use this medicine only as directed. Do not use more of it and do not use it more often than your doctor ordered. To do so may increase the chance of too much medicine being absorbed into the body and the chance of side effects.
If your doctor ordered two different eye drops to be used together, wait at least 5 minutes between the times you apply the medicines. This will help to keep the second medicine from “washing out” the first one.
It is important that your doctor check your eye pressure at regular visits to make certain that your glaucoma is being controlled.
Contact lenses should be removed before you use this medicine. You should wait at least 15 minutes after using the eye drops before reinserting them.
To use the eye drops:
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
If you miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Before the bottle has been opened for the first time, store in the refrigerator. After the bottle has been opened, store at room temperature (up to 25 °C [77 °F]) for up to 6 weeks, or in the refrigerator.
Precautions While Using This Medicine:
While you are using latanoprost, the iris (colored part) of your treated eye(s) may slowly become more brown in color. This is more likely to happen if you have blue-brown, gray-brown, green-brown, or yellow-brown eyes. The change in color of the iris is noticeable usually within several months or years from the start of treatment with latanoprost. In addition, there may be a darkening of eyelid skin color. Also, your eyelashes may become longer, thicker, and darker. These changes to the iris, eyelid, and lashes may be permanent even if you stop using latanoprost. Also, these changes to the iris, eyelid, and lashes will affect only the eye being treated with latanoprost. Therefore, if only one eye is being treated, only that eye may develop darker iris, eyelid, and eyelashes and other changes to the eyelashes, and you may have differently appearing eyes. Check with your doctor if you have any questions about this.
Latanoprost may cause your eyes to become more sensitive to light than they are normally. Wearing sunglasses and avoiding too much exposure to bright light may help lessen the discomfort.
