Oophorectomy
"After using Vivelle patch for a number of years following a complete hysterectomy, my insurance company refused to pay for it at the same level due to the Mylan generic. Within a few weeks of switching to the generic, I began to develop adverse symptoms (insomnia, breathing difficulties, anxiety, constant headache). When I made the connection and switched back to Vivelle, the symptoms subsided. Unfortunately, my insurance company refuses to pay for the brand name at the same level, but this is not the same drug. Now instead of paying $40 for a 3-month supply, my cost is over $150 to obtain the brand name product."
