I had the same thing. It is due to the excessive amount of Vitamin E in Areds -triple the required RDA amount - see the Mayo Clinic site for cautions about Vitamin E. If you are taking certain medications such as blood pressure & others it can cause reactions. You can take the other ingredients in Ared2 in separate vitamin pills, the zinc & copper combination & Lutein-zeaxanthin combination in another vitamin pill & probably enough vitamin E in a multivitamin. Talk to your pharmacist or licensed hospital dietitian.
