Birth control pills containing norgestimate, a synthetic progestin, are commonly used for contraception and sometimes for acne treatment. Norgestimate is almost always combined with the estrogen ethinyl estradiol. These pills fall into two main categories based on their hormone dosage throughout the cycle: monophasic and triphasic.
Monophasic Norgestimate Birth Control Pills
Monophasic pills maintain a constant hormone dose for the first three weeks of the cycle, followed by inactive pills. This offers a steady hormone level. Active pills typically contain 0.25 mg of norgestimate and 35 mcg of ethinyl estradiol.
Examples of monophasic norgestimate pills:
- Sprintec: A generic option.
- Mono-Linyah: Another generic.
- MonoNessa: Contains 0.25mg norgestimate and 35mcg ethinyl estradiol.
- Previfem: A generic formulation.
- Estarylla: A generic version.
- Ortho-Cyclen: Often available generically.
Triphasic Norgestimate Birth Control Pills
Triphasic pills with norgestimate have three distinct hormone levels during the active pill phase. The norgestimate dose changes, while ethinyl estradiol often stays constant. This aims to mirror the body's natural cycle. Lower-estrogen triphasic options also exist.
Examples of triphasic norgestimate pills:
- Ortho Tri-Cyclen: Brand name, with generics like Tri-Sprintec and Tri-Nessa.
- Ortho Tri-Cyclen Lo: Low-estrogen version, with generics like Tri-Lo-Sprintec and Tri-Lo-Mili.
- Tri-Sprintec: Generic Ortho Tri-Cyclen.
- Tri-Linyah: Generic equivalent.
- Tri-Estarylla: Generic triphasic.
- Tri-Mili: Another generic triphasic.
- Tri-Lo-Sprintec: Generic low-estrogen triphasic.
How to Choose Between Monophasic and Triphasic Pills
Choosing between monophasic and triphasic depends on individual health and how one responds to hormone levels. Both are effective, but one might offer better cycle control or fewer side effects for a particular person. Discussion with a healthcare provider is essential.
| Feature | Monophasic Norgestimate Pills | Triphasic Norgestimate Pills |
|---|---|---|
| Hormone Dosage | Consistent dose of norgestimate and ethinyl estradiol in all active pills. | Three different phases of hormone levels in the active pills. |
| Hormone Fluctuation | Lower day-to-day hormonal fluctuation for some users. | Designed to mimic the body's natural cycle with varying hormone levels. |
| Common Examples | Sprintec, Mono-Linyah, Previfem. | Tri-Sprintec, Ortho Tri-Cyclen, Tri-Lo-Sprintec. |
| Best For | Individuals who may prefer a steady hormonal level and find it minimizes side effects related to hormonal shifts. | Individuals who may benefit from a more natural hormone progression or have specific sensitivities to monophasic regimens. |
Important Considerations and Risks
Norgestimate pills are not suitable for everyone. Discuss your medical history with your doctor. Combination birth control pills have risks, especially for certain groups.
Key risks include:
- Blood clots: Increased risk of blood clots, heart attack, or stroke, particularly for smokers over 35.
- Cardiovascular disease: Not recommended for those with heart disease, uncontrolled high blood pressure, or circulation problems.
- Liver conditions: Contraindicated for individuals with liver disease or tumors.
- Migraine with aura: Increased stroke risk for those with certain migraines.
Oral contraceptives do not protect against STDs. Use condoms for protection.
Conclusion
Norgestimate is present in various monophasic and triphasic combination birth control pills, including brands like Sprintec and Ortho Tri-Cyclen and their generics. Monophasic pills offer consistent hormone doses, while triphasic pills have varying doses to simulate natural cycles. A medical consultation is crucial to determine the safest and most effective option based on your health history and risks.
