We have been trying to work out a best way for contraception and have been to 2 gynacs. We got pills prescribed by both and are now trying to figure which one will have minimum side effects. Can someone clarify if Novelone (prescribed by both) or Loette (reputed brand pfizer) is better? We also got Yasmin, Dronis 20 prescribed which cost double of Novelon. Can someone shed some light on what's the difference and why some pills cost double of others? Are they any better? Do they have lesser side effects?
