Understanding Cerazette and Its Equivalents
Cerazette is a brand name for a type of oral contraceptive known as a progestogen-only pill (POP), or "mini-pill" [1.2.1]. The key to finding a pill that is the same as Cerazette is to look for its active ingredient: desogestrel [1.2.2]. Any contraceptive pill that contains 75 micrograms of desogestrel is pharmacologically equivalent to Cerazette [1.2.1]. These pills work primarily by preventing ovulation (the release of an egg), which is a characteristic that makes desogestrel-based POPs highly effective, comparable to some combined pills [1.2.5]. They also work by thickening the cervical mucus to make it more difficult for sperm to enter the womb [1.2.5].
Because they do not contain estrogen, desogestrel pills like Cerazette are a suitable option for many women who cannot take estrogen-containing contraceptives. This includes women who are breastfeeding, those over 35 who smoke, or individuals with certain health conditions like a history of blood clots [1.2.6, 1.4.3].
Generic and Branded Alternatives
When a medication's patent expires, other pharmaceutical companies can produce and sell it under its generic name or different brand names. This is the case with Cerazette. The generic version is simply called 'Desogestrel' [1.4.2].
Several other branded versions are available that contain the exact same active ingredient and dosage (75mcg desogestrel). These include, but are not limited to:
- Cerelle: Often cited as a direct equivalent to Cerazette, with the main difference being the manufacturer and often the cost [1.4.4, 1.4.6].
- Hana: Notably available over-the-counter in some regions after a pharmacy consultation, offering more convenient access [1.4.3].
- Zelleta [1.4.2]
- Feanolla [1.4.2]
- Desomono [1.4.2]
- Desorex [1.4.2]
Since these pills all contain the same active substance, they work in the same way and have the same effectiveness and side effect profile [1.3.6]. The choice between them often comes down to availability, cost, and what a specific healthcare provider or pharmacy stocks.
Comparison: Desogestrel POPs vs. Other Contraceptives
It's useful to understand how desogestrel pills compare to other forms of oral contraception.
| Feature | Desogestrel POP (e.g., Cerazette) | Traditional POP (e.g., Norgeston) | Combined Pill (e.g., Microgynon) |
|---|---|---|---|
| Hormones | Progestogen-only (Desogestrel 75mcg) [1.2.2] | Progestogen-only (e.g., Levonorgestrel) [1.5.3] | Estrogen and Progestogen [1.2.6] |
| Primary Action | Primarily inhibits ovulation [1.2.5] | Primarily thickens cervical mucus [1.5.2] | Inhibits ovulation [1.2.6] |
| Missed Pill Window | 12 hours [1.5.4] | 3 hours [1.5.4] | 24 hours (depending on week) |
| Suitability | Suitable for most women, including those who cannot take estrogen (e.g., breastfeeding, smokers over 35) [1.2.6]. | Similar to desogestrel POPs but with a stricter time window for taking it. | Not suitable for women with contraindications to estrogen (e.g., history of blood clots, certain migraines) [1.8.2]. |
| Period Changes | Bleeding may become irregular, lighter, more frequent, or stop altogether [1.2.6]. | Irregular bleeding is common. | Typically results in regular, predictable withdrawal bleeds during the pill-free week. |
Potential Side Effects and Considerations
Like all medications, desogestrel can cause side effects, though not everyone experiences them. It's important to be aware of them when starting or switching contraceptives.
Common Side Effects (may affect up to 1 in 10 women) [1.2.6, 1.6.4]:
- Changes in menstrual bleeding (irregular periods or no periods at all)
- Altered or depressed mood
- Decreased libido
- Headache
- Nausea
- Acne
- Breast pain
- Increased body weight
Uncommon Side Effects (may affect up to 1 in 100 women) [1.2.6, 1.6.4]:
- Vaginal infection
- Difficulty wearing contact lenses
- Vomiting
- Hair loss
- Painful menstruation
- Ovarian cysts
- Tiredness
Most side effects, if they occur, are more common in the first few months as the body adjusts to the hormone [1.4.3]. If side effects are severe or persistent, it is crucial to consult a doctor.
Who Should Avoid Desogestrel?
This type of contraception is not suitable for everyone. You should not take desogestrel if you:
- Are pregnant or think you might be [1.8.5].
- Have an active blood clot (venous thromboembolism) [1.8.5].
- Have or have had jaundice or severe liver disease [1.8.5].
- Have a known or suspected cancer that is sensitive to sex hormones, such as certain types of breast cancer [1.8.5].
- Have any unexplained vaginal bleeding [1.8.5].
Conclusion
In summary, any pill containing 75mcg of desogestrel is the same as Cerazette in its active function. This includes the generic version 'Desogestrel' and other brands like Cerelle and Hana. They offer a highly effective, estrogen-free contraceptive option suitable for a wide range of women. While the branding and packaging differ, the core medication, its effectiveness, and how you should take it remain the same. Always consult with a healthcare professional or pharmacist before starting or switching contraceptive methods to ensure it is the right and safe choice for your individual health circumstances.
