If any medication gets into the eye, do not rinse your eye. It is not likely to cause any harm if this medication gets into the eye, because it is the same medication that is used in the eyes to treat glaucoma. To avoid contamination, do not touch the dropper tip or let it touch your eyelashes or any other surface. Do not rinse the dropper. Replace the dropper cap after each use, and keep the cap tightly closed. Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each evening. Do not use more of this medication than recommended. Using more will not make this medication work faster. It may take up to 2 months before the full benefits of using this medication are seen. When this medication is stopped, expect the appearance of the eyelashes to return to the way they looked before starting treatment with bimatoprost. It is possible that the effects between your two sets of eyelashes may not be the same. There may be differences in eyelash length, thickness, fullness, color, number or direction of growth. If any of these occur, talk to your doctor.
