It's a oral tablet. But not Hrt. It's classed as a Serm and targets the vagina, a bit like tamoxifen targets breast cancer and can be used by women that have had breast cancer. I thought I was on a winner this time. I had previously used Vagifem for a couple of years with no problems at all but since April had nothing but constant burning and changing the dosage made no difference. It was making me ill as I couldn't sleep. Hence the change.
