Co-cyprindiol is a contraceptive pill used to treat moderate-to-severe acne caused by hormonal changes. This contraceptive pill contains a combination of ethinylestradiol and cyproterone acetate. Co-cyprindiol is available for purchase online offering a convenient solution for hormonal acne.
Co-cyprindiol works by regulating hormone changes that lead to acne breakouts. Cyproterone acetate helps decrease your body’s production of androgens, which are responsible for generating sebum, a sticky, oily substance the body produces that leads to blocked pores and acne. Another benefit is that androgens contribute to increased hair growth, so lowering their levels can help decrease unwanted body hair.
Co-cyprindiol prevents ovulation. This means that sperm cannot fertilise an egg. Co-cyprindiol also thickens mucus in the womb, making it difficult for sperm to pass through.
Important note: Medication should be kept out of sight and reach of children, away from direct light and heat, and stored in a cool and dry place For more information, please read the patient information leaflet.
If you have missed taking one pill and it is within a 12-hour window your contraceptive protection remains intact by promptly taking the missed pill and continuing with the subsequent pills as scheduled.
Should you be over 12 hours late or miss more than one pill your contraceptive protection might diminish.
In this scenario you should:
Active ingredients: cyproterone acetate (2 milligrams) and ethinylestradiol (35 micrograms).
Inactive ingredients: lactose monohydrate, maize starch, povidone, purified talc, magnesium stearate, hypromellose, propylene glycol, titanium dioxide (E171), and quinoline yellow (E104).
Whilst the active ingredient will remain the same, the inactive ingredients may differ amongst brands. You should read the patient information leaflet supplied with your medication, for a full list of ingredients.
Important note: You should always disclose your full medical history to your doctor or pharmacist, so that they can ensure treatment is safe for you to take.
Yasmin is sometimes recommended as an acne treatment and works similarly to Co-cyprindiol by controlling sebum generation, effectively supporting the control and handling of acne.
Similar to any medication, Co-cyprindiol tablets can cause side effects, although not everyone may encounter them.
Side effects of co-cyprindiol include:
Common – affecting up to 10% of users:
Uncommon – affecting up to 1% of users:
Rare – affecting up to 0.1% of users:
Should you notice any of the following symptoms, discontinue the tablets and seek urgent medical assistance:
For a full list of side effects, read the patient information leaflet and inform your doctor or pharmacist if you experience any.
You should not use co-cyprindiol if:
You should not use Co-Cyprindoil if you are pregnant or at risk of pregnancy, or if you are breastfeeding.
While co-cyprindiol is an effective contraceptive pill, it is not primarily prescribed for this purpose alone. It is reserved for those who require treatment for hormonal acne and wish to take an oral contraceptive.
For more detailed information, please refer to the Patient Information Leaflet.
It is unlikely that Co-Cyprindiol can cause your periods to stop. In the 7-day pill-free week you should experience bleeding. If you don’t, you should speak to your doctor or pharmacist, or take a pregnancy test as you may be pregnant.
It is unlikely that Co-Cyprindiol will make acne worse. This medication exerts an anti-androgenic effect that can help in clearing up your skin when acne is caused by androgen hormone (hormonal acne).
Hormonal contraceptives can cause fluid retention and some weight gain. This side effect may not be experienced by all women taking the medication.
Co-Cyprindiol is an effective hormonal contraceptive if taken exactly as directed and at the same time each day but it should not be used for the sole purpose of contraception as there are other better options. Co-Cyprindiol is typically prescribed to women suffering moderate-severe acne and/or hirsutism who wish to take a contraceptive.
Co-Cyprindiol must NOT be used if you have (or had) migraines with visual disturbances such as seeing blind spots, light flashes, and feeling of tingling in hands and feet. If you experience severe, sudden headaches or worsening of migraine you should stop taking Co-Cyprindiol immediately and contact your physician or pharmacist.
Co-Cyprindiol can cause depressed and altered mood (see side effects above) as with all hormonal contraceptives. Talk to your physician or pharmacist if you experience mood changes or depressive symptoms.
