Opticrom Eye Drop is a medication utilized to treat allergic eye diseases. It helps provide relief from allergy symptoms such as inflammation (redness and swelling), itchiness, and watery eyes. Opticrom Eye Drop is for external use only. Follow the instructions given by your doctor and use this medication regularly to get the most benefit. You should gently squeeze the dropper and place the medication inside the lower eyelid and wipe off extra liquid. Always wash your hands and do not touch the end of the dropper. This could infect your eye. Make sure you remove contact lenses if you wear them and wait for at least 15 minutes before putting them back. Never use a bottle if the seal is broken before you use it for the first time. It is generally safe to use, but you might experience a stinging sensation on application. If these bother you or you experience any other side effects, let your doctor know. There may be ways of reducing or preventing them.
