Side effects of emergency contraceptive pills?
Hello Doctor:
1.
I was diagnosed with polycystic ovary syndrome at the hospital, and my doctor recommended that I take oral contraceptives to regulate my menstrual cycle.
The brand I am currently taking is Alesse (active ingredients: Cyproterone Acetate 2 mg & Ethinyl Estradiol 0.035 mg).
I am wondering if the side effects of this medication could cause a decrease in libido.
In the first year of taking it, I was fine; the side effects were mostly nausea and vomiting.
However, recently I have noticed a significant decrease in my sexual desire, and the sensations during intercourse are not as intense.
Could this be related to the oral contraceptive?
2.
In addition to the oral contraceptive, I am also regularly taking antidepressants and sleep medications for depression.
I am curious if there could be any interactions between these two types of medications.
3.
I have been on antidepressants for about a year and a half, and I have been taking the oral contraceptive for nearly a year as well, with no changes in medication.
Initially, my libido and sexual experiences were normal, similar to before I started the medications.
However, I am unsure why, in the past few months, I have started to experience a decrease in libido, difficulty reaching orgasm, and increased dryness.
I would like to know which medication might be affecting me.

Hello, the common side effects of oral contraceptives include: headaches, dizziness, heavy or irregular menstrual bleeding, nausea, vomiting, edema, increased cervical mucus, cervical hypertrophy, increased appetite, weight gain, skin itching, acne, fatigue, depression, flushing, feelings of weakness, breast tenderness, and increased risk of yeast infections, among others.
Medications that may interact with oral contraceptives include:
1.
Antibiotics (Penicillin, Cephalosporins, Erythromycin, Sulfonamides, Bactrim, Chloramphenicol) - may reduce the intestinal flora that aids in absorption, thereby decreasing the effectiveness of the contraceptive.
2.
Sedatives (Barbiturates) - increase the metabolism of contraceptives, reducing their effectiveness.
3.
Antiepileptic drugs (Primidone, Phenytoin, Carbamazepine) - increase the metabolism of contraceptives, reducing their effectiveness.
4.
Tuberculosis medications (Rifampicin, Isoniazid).
5.
Antidiabetic medications (Rosiglitazone).
6.
Acetaminophen and Ascorbic acid (Vitamin C) - may inhibit estrogen metabolism, leading to increased concentrations and a higher incidence of side effects.
7.
Oral contraceptives can affect the action of anticoagulants.
8.
Smoking - increases the metabolism of contraceptives, reducing their effectiveness.
You should discuss any potential side effects of the antidepressants and sedatives you are taking with your prescribing physician.
Thank you! Wishing you safety and health.
Dr.

More Info
Understanding the side effects of birth control pills, particularly in relation to libido, is crucial for many women who are managing their reproductive health alongside other medical conditions. In your case, you are taking a combination oral contraceptive pill (OCP) containing Cyproterone Acetate and Ethinyl Estradiol, which is commonly prescribed for conditions like polycystic ovary syndrome (PCOS).
1. Impact of Birth Control Pills on Libido: It is well-documented that hormonal contraceptives can affect libido in some women. While many women experience no change in sexual desire, others may notice a decrease. The hormones in birth control pills can influence various bodily functions, including the hormonal balance that regulates libido. Cyproterone Acetate, in particular, is an anti-androgen that can lower testosterone levels, which may contribute to reduced sexual desire. If you have noticed a significant change in your libido over the past few months, it is possible that the birth control pills are a contributing factor.
2. Interaction with Antidepressants and Sleep Medications: You mentioned that you are also taking antidepressants and sleep medications. Certain antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), are known to have sexual side effects, including decreased libido and difficulty achieving orgasm. When combined with hormonal contraceptives, the effects on libido can be compounded. It is essential to discuss these interactions with your healthcare provider, as they may need to adjust your medications or explore alternative treatments to mitigate these side effects.
3. Changes Over Time: It is not uncommon for women to experience fluctuations in libido over time, even when taking the same medications. Factors such as stress, relationship dynamics, hormonal changes, and overall mental health can all play significant roles. Since you have been on both the birth control pill and antidepressants for an extended period, it is worth considering whether other lifestyle factors or emotional states may be influencing your sexual desire.
4. Recommendations: If you are concerned about the decrease in libido and its impact on your sexual health, it is advisable to consult with your healthcare provider. They can evaluate your current medication regimen, discuss potential side effects, and consider alternative options. For instance, switching to a different formulation of birth control that has a lower risk of affecting libido or adjusting your antidepressant dosage may be beneficial. Additionally, exploring non-pharmacological approaches to enhance sexual desire, such as therapy or counseling, may also be helpful.
5. Conclusion: In summary, hormonal contraceptives like the one you are taking can indeed affect libido, and when combined with other medications, the effects can be more pronounced. It is essential to have open communication with your healthcare provider about any changes you experience, as they can help tailor a treatment plan that addresses both your contraceptive needs and your overall well-being. Remember, sexual health is an integral part of overall health, and it is important to address any concerns you may have.
