Irregular Bleeding and Menstrual Changes
One of the most commonly reported disadvantages of Cerelle is its impact on menstrual bleeding patterns, which can be highly unpredictable. Unlike combined oral contraceptives that often provide predictable monthly bleeds, Cerelle can lead to a variety of experiences. Many users experience breakthrough bleeding or spotting, particularly during the first few months as their body adjusts to the hormone desogestrel. For some, this can settle, but for others, the irregular bleeding persists. Approximately 20% of progestogen-only pill users experience bleeds lasting longer than 14 days. The bleeding can be frequent, infrequent, or stop altogether (amenorrhea), which can be disconcerting for some individuals. This occurs because the desogestrel in Cerelle thins the lining of the womb, causing it to shed irregularly.
Mood and Mental Health Impacts
Cerelle, and hormonal contraceptives in general, can significantly impact mood and mental health for some individuals. The hormonal changes from taking the progestogen-only pill have been reported to cause a range of emotional side effects.
Commonly reported mood-related disadvantages include:
- Mood Alterations and Depression: Many users report experiencing low mood, emotional sensitivity, and even depression, especially during the initial months. A large study linked hormonal contraception to an increased risk of first-time antidepressant use and depression diagnoses, particularly in adolescents.
- Decreased Libido: A reduced sexual drive is a frequently cited side effect, impacting relationships and overall well-being.
- Anxiety and Panic Attacks: While less common, there are reported cases linking desogestrel use to anxiety and panic attacks. The mechanism is thought to be related to the influence of progesterone on neurotransmitters.
Physical Side Effects
Beyond menstrual and mental health changes, users may experience a number of physical side effects while on Cerelle.
Weight Fluctuations and Appetite
Some individuals report weight gain while using Cerelle, though medical sources suggest there is no definitive evidence to prove a causal link. Weight changes may be related to fluid retention or altered appetite caused by hormonal fluctuations. User reviews, however, often cite weight gain as a reported side effect.
Skin and Hair Changes
Cerelle can affect skin and hair condition. The progestogen can increase the production of sebum, which can lead to or worsen acne for some users. Conversely, some women experience hair loss or increased body hair, which can be distressing. These effects are not experienced by everyone and can sometimes improve over time.
Other Common Symptoms
- Headaches and migraines
- Nausea, particularly in the initial adjustment period
- Breast pain or enlargement
- Ovarian cysts, which are usually harmless and resolve on their own
Comparison: Cerelle (POP) vs. Combined Pill
Choosing between a progestogen-only pill (POP) like Cerelle and a combined oral contraceptive involves weighing different side effect profiles and usage requirements. The following table compares some key disadvantages.
| Feature | Cerelle (Progestogen-Only Pill) | Combined Pill (Estrogen + Progestogen) |
|---|---|---|
| Bleeding Pattern | Highly unpredictable; can be irregular, frequent, or absent. | Usually regular, predictable monthly bleeds. |
| Timing Requirements | Must be taken within a 12-hour window daily for effectiveness. | Typically has a wider 24-hour window, making it less strict for daily use. |
| Acne Effects | May worsen existing acne due to increased sebum production. | Often improves acne by reducing androgens. |
| Blood Clot Risk | Generally considered a very low risk for blood clots. | Higher risk of venous thromboembolism (VTE) and arterial thromboembolism. |
| Side Effects | Often focused on menstrual and mood changes, plus some physical effects. | May have a wider variety of side effects, though not universally more severe. |
| Suitability | Suitable for smokers over 35, individuals with high blood pressure, or those sensitive to estrogen. | Not suitable for individuals with certain health conditions, including a history of blood clots or some types of migraine. |
Conclusion
While Cerelle offers a valuable contraceptive option, particularly for those who cannot take estrogen, it is important to be aware of the potential disadvantages. The most significant downsides for many users involve unpredictable bleeding patterns and mood disturbances, including depression and decreased libido. Other physical side effects, such as acne, weight gain, and breast pain, are also common. Understanding these drawbacks and comparing them with alternative methods, like the combined pill, is crucial. It is highly recommended to discuss these potential side effects and personal health history with a healthcare provider to determine if Cerelle is the right choice for you. Keeping a record of any symptoms can help inform this discussion over time.
