Key takeaways
Sprintec (norgestimate/ethinyl estradiol) and Tri-Lo-Sprintec (norgestimate/ethinyl estradiol) are both combined oral contraceptives, but they have some key differences. Sprintec is a monophasic birth control, meaning all active tablets contain the same dose of hormones, while Tri-Lo-Sprintec is triphasic, with three different doses of hormones throughout the cycle. Tri-Lo-Sprintec has a lower dose of estrogen (25 mcg) compared to Sprintec (35 mcg), which might be preferable if you want a birth control with less estrogen. Additionally, Tri-Lo-Sprintec is not FDA-approved for treating acne, unlike Tri-Sprintec, another triphasic option. Both medications require you to take one active pill daily for 21 days, followed by 7 placebo pills. Both options are highly effective in preventing pregnancy if taken as directed, but you should discuss with your provider to determine which is best for you.
