"i have tried several different oral contraceptives and found to do the best with a tri-phasic form specifically ortho-tri-cyclen lo.  then cvs changed me to a generic equivalent tri-lo- sprintec which i did fine on. of course when the generic tri-lo-estarylla came out i was switched to that again by my pharmacy/insurance.  

though the active ingredients and dosing is the same, i&#039;m having a hard time with this one. i&#039;ve been experiencing incredible  fatigue,weakness, chest discomfort, and body twitches. i have a new appreciation for my patients who tell me the generics are not the same. everyone&#039;s body reacts differently and can be sensitive to particular inactive ingredients or color fillers."
