What is the difference between various brands of birth control pills?

Minimal: Just like the 'nuts and bolts' of different makes of cars are essentially the same, the differences between various kinds of birth control pills are minimal. There is nothing all that better or worse between different brands based on price or how new they are.

No clear differences: There is no clear evidence that users of any one particular pill will have more or fewer side effects.Every person is different, & success with pills can't be predicted--you have to try it on (like finding the best pair of blue jeans).Most people do well on the 1st pill they try, and almost everyone can find a pill that works.Give it a fair try ~3 months if you can, as many mild side effects go away.
