Do not touch the tip of the opened container and do not touch the surface of the eye with the tip of the container. As VISLUBE does not contain preservatives it should be used and discarded after opening. However, based on data from in-use stability study, if used as recommended and carefully recapped, the solution can be used within 12 hours after opening. Do not use VISLUBE if the container is damaged. If discomfort persists while using VISLUBE or reappears after discontinuation of treatment, consult a physician. Patients who experience blurred vision after application of the eye drops should not drive or use machinery until their vision has cleared.
