Opcon-A

This is an over-the-counter allergy drop used for itching and swelling of the eyelids.  This drop is the same as the competing brand Naphcon-A. Opcon-A contains both an antihistamine and a vasoconstrictor. While effective for short term relief, I prefer the more powerful second generation allergy drops like Alaway/Zaditor and Patanol.
