Yes, continued use of Xalatan may cause a change in the color of the iris, particularly brown pigmentation. This color change is more common in people who have mixed color eyes (blue-brown, grey-brown, yellow-brown or green-brown). The change may be more noticeable if it is used in only one eye. This change in color is likely to be permanent. Additionally, the eyelashes may also become denser and the color of the eyelids may darken. However, this is usually temporary and reverts to normal once the use of Xalatan is discontinued.

Yes, the unopened bottle needs to be refrigerated at 2° to 8°C (36° to 46°F). However, once the bottle is opened for use, it may be stored at room temperature up to 25°C (77°F) for not longer than 6 weeks.

You should contact your doctor immediately if you develop an eye infection, injury, conjunctivitis, or an eyelid reaction. Along with that, the doctor should be informed if you have undergone any eye surgery earlier. Use Xalatan as prescribed by the doctor.

It is recommended to use Xalatan in the evening for best results. Xalatan, when used in the evening for the first few days, showed significantly effective results in lowering the eye pressure. The effect of this medicine remains for about 24 hours after administration.

If you have to use other eye drops, wait for at least 5 minutes before using them. You should inform your doctor about any other medicine which you are using since it may interfere with the working of Xalatan.

After using the eye drops you should close your eyes for at least 2-3 minutes so that the medicine does not run off and gets absorbed in the eye.

The pressure in the eyes starts decreasing after about 3-4 hours of using Xalatan and the maximum effect is reached after 8-12 hours.

Yes, you can use contact lenses while using Xalatan. However, remove your contact lenses before instilling Xalatan. You can re-insert the lenses 15 minutes after instilling Xalatan. Contact your doctor if eye irritation occurs and persists.
