What is Sprintec?

Sprintec is a prescription oral contraceptive that contains a combination of two hormones: norgestimate (a progestin) and ethinyl estradiol (an estrogen). These hormones work together to prevent pregnancy by stopping ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining to prevent implantation of a fertilized egg.

What is Sprintec used for?

• Preventing pregnancy
• Regulating menstrual cycles
• Reducing menstrual cramps
• Treating acne in females 15 years and older

How Sprintec Works

• Prevents ovulation (release of eggs from ovaries)
• Thickens cervical mucus to block sperm entry
• Alters uterine lining to reduce chance of egg implantation

When Does Sprintec Start Working?

Sprintec can begin preventing pregnancy within a few days, depending on when you start the medication. Full effectiveness is typically reached within 7 days. Use backup contraception (e.g. condoms) during the first week.

Dosage

Sprintec is taken in a 28-day cycle: 21 active hormone pills followed by 7 placebo pills. Take one pill at the same time every day. Start a new pack immediately after finishing the previous one, without missing days between packs.

FAQs

Why is Sprintec considered a monophasic birth control?

Sprintec is monophasic because all 21 active pills contain the same hormone dose. This helps reduce hormone fluctuations and makes the regimen easier to follow.

Can I skip Sprintec if I don't have sex often?

No. Sprintec must be taken daily regardless of sexual activity to maintain effectiveness.

What if I vomit or have diarrhea after taking Sprintec?

If this occurs within 3-4 hours of taking a pill, it may not be fully absorbed. Follow missed pill instructions and use backup contraception if needed.

When can I start Sprintec?

Start on the first day of your period or the first Sunday after your period begins. Use backup contraception for 7 days unless otherwise directed by your provider.
