This triphasic combination pill contains norgestimate (a progestin) and ethinyl estradiol. Instead of delivering the same hormone level every day, it shifts in three phases to more closely mimic the body’s natural cycle. For many users, that means steady mood, fewer hormone swings, predictable periods, and reliable pregnancy protection when taken as directed. It’s often chosen for lighter menstrual bleeding, improved cramping, and acne-support benefits due to norgestimate’s lower androgenic activity.
Norgestimate 0.18mg, 0.215mg, 0.25mg | Ethinyl estradiol 0.035 mg (Tri-Femynor, Tri-Previfem, Tri-Sprintec)

❓ Frequently Asked Questions
💊 How effective is this pill?
With perfect use, it’s over 99% effective. With typical day-to-day use, about 91% effective. Missing pills or taking them at irregular times reduces effectiveness.
🩸 Will my period change?
Many users experience lighter periods, less cramping, and more predictable cycles. Some may have spotting during the first 2–3 months while the body adjusts.
😊 Can this help with acne?
Yes. Norgestimate-based pills are commonly used for patients with acne, oiliness, or hormonal breakouts.
⏳ What if I miss a pill?
If you miss one active pill, take it as soon as you remember and continue the pack. Missing more than one can increase pregnancy risk—backup contraception may be needed.
🏃♀️ What if I vomit after taking it?
If vomiting or severe diarrhea occurs within about 3 hours of taking a pill, it may not be absorbed. Take the next pill or use backup protection for 7 days.
😕 Will it cause weight gain?
Significant weight gain is uncommon. Some people may notice mild water retention, breast tenderness, or appetite shifts early on.
🌞 Can I be in the sun / will it cause skin changes?
Some users may develop melasma—dark patches of skin. Sun protection can reduce this risk.
🧪 Does it protect against STDs?
No. It prevents pregnancy only. Use condoms for protection against sexually transmitted infections.
🤰 What happens if I get pregnant on the pill?
Stop taking the pills and contact your clinician. They may perform a pregnancy test and advise next steps. Birth control pills are not recommended during pregnancy.
🍼 Can I take this while breastfeeding?
Combined pills can decrease milk supply, especially in early postpartum months. Progestin-only pills are usually preferred while breastfeeding—ask your clinician.
💊 Is it safe to take with other medications?
Some medications, including certain seizure drugs, antibiotics, or supplements like St. John’s Wort, may decrease effectiveness. Always tell your clinician what you take.
🩺 Do I need a Pelvic exam or lab work first?
Most patients do not need a pelvic exam to start combined pills. Your clinician will review medical history, risks, and blood pressure first.
💥 Can I skip my period with this pill?
Triphasic pills are meant to be taken in sequence, so skipping periods is less predictable than with monophasic pills. Speak with your clinician if continuous cycling is desired.
🧬 Will it affect my fertility?
No. Fertility typically returns quickly after stopping—often within 1–2 cycles.
🧘♀️ What if I get mood changes?
Mood changes are possible. If symptoms become bothersome, contact your clinician to adjust the dose or switch formulations.
