How long does it take for a triphasil (ethinyl estradiol and levonorgestrel) to work?

Specializes in Obstetrics and Gynecology
Triphasil (ethinyl estradiol and levonorgestrel): If you mean the birth control pill, you want to use condoms during the first cycle, and as of the second pack you can expect full protection from getting pregnant.
