This is a prescription vitamin used to treat macular degeneration and dry eye. It contains most of the vitamins from the AREDS Study, along with the Omega-3 fatty acids and plant pigments (lutein and zeaxanthin) from the AREDS 2 Study.  Tozal also contains taurine, a protein that is commonly found in energy drinks that is “supposed” to increase energy production in the retina. I rarely prescribe this medicine, as good AREDS vitamins (Ocuvite, PreserVision, I-CAPS) are available over the counter without a prescription. I will use it on occasion if your prescription drug coverage is excellent, or I am worried about your getting the proper eye vitamins (such as someone in a nursing home who can’t reliably get non-prescription medications).
