birth control
"I've been using Tri Sprintec for almost a year. I'm not sexually active, but was prescribed it for month-long PMS, spotting and irregular periods. By irregular I mean 27 days one month, 30 days the next month, 25 the next, and so on. I have 28 days all the time now, occasionally 27. PMS is much better, skin cleared, and I'm much more emotionally stable! I do notice PMS in the last week, but that's to be expected as there's no hormones that week. The other thing I have noticed is that it does dry out my skin, eyes, scalp and vaginal  area. I believe that's due to the same stuff that keeps your skin clear. I did notice a bit of nausea in the beginning, but that should go away. It helps to take it at night. All in all, great pill!"
