I was on Ortho Tri sprintec when I was on the pill. It is a low hormone pill. Like most pills, you can skip the sugar pills with no ill effect. Also, even without ANY insurance, it was only 9 bucks a month at Walmart. If you don't have insurance, the pharmacy won't give you any issues about WHEN you refill it.
Now I'm sure there are generic versions of other pills, but not Ortho.
