Uses
This medication is a combination of 2 hormones: an estrogen (estetrol) and a progestin (drospirenone). This product is used to prevent pregnancy.
Besides preventing pregnancy, birth control pills may make your periods more regular, decrease blood loss and painful periods, and decrease your risk of ovarian cysts.
This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). To decrease your risk of infection, always use an effective barrier method (latex or polyurethane condom/dental dams) during all sexual activity.
How To Use
Read the Patient Information Leaflet provided by your pharmacist before you start using this product and each time you get a refill. The leaflet contains very important information on when to take your pills and what to do if you miss a dose. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, with or without food, usually once daily. Pick a time of day that is easy for you to remember, and take your pill at the same time each day, 24 hours apart.
Taking this medication after your evening meal or at bedtime may help if you have stomach upset or nausea with the medication. You may choose to take this medication at another time of day that is easier for you to remember. No matter what dosing schedule you use, it is very important that you take this medication at the same time each day, 24 hours apart.
Follow the package instructions to find the first tablet, start with the first tablet in the pack, and take them in the correct order. Do not skip any doses. Pregnancy is more likely if you miss pills, start a new pack late, or take your pill at a different time of the day than usual.
Vomiting or diarrhea can prevent your birth control pills from working well. If you have vomiting or diarrhea, you may need to use a back-up birth control method (such as condoms, spermicide). Follow the directions in the Patient Information Leaflet and check with your doctor or pharmacist for more details.
Your pill pack contains 24 pills with active medication (with hormones). It also contains 4 reminder pills (without hormones) at the end of the pack. Take one active pill (with hormones) once daily for 24 days in a row. After you have taken the last active pill, take a reminder pill (without hormones) once daily for 4 days in a row unless otherwise directed by your doctor. You should have your period within 3 days after you take the last active tablet in the cycle during the fourth week of the pack. After you have taken the last inactive tablet in the pack, start a new pack the next day whether or not you have your period. If you do not get your period, consult your doctor.
If this is the first time you are using this medication and you are not switching from another form of hormonal birth control (such as the patch, other birth control pills), take the first tablet in the pack on the first day of your period. If you start on the first day of your period, you do not need to use back-up birth control the first week. For the first cycle of use only, use an additional form of non-hormonal birth control (such as condoms, spermicide) for the first 7 days if you are instructed to start this medication on any day other than the first day of your period.
Ask your doctor or pharmacist for information about how to switch from other forms of hormonal birth control (such as patch, other birth control pills) to this product. If any information is unclear, consult the Patient Information Leaflet or your doctor or pharmacist.
Side Effects
Nausea, vomiting, headache, abdominal cramps/bloating, breast tenderness, swelling of the ankles/feet (retaining fluid), or weight change may occur. Vaginal bleeding between periods (spotting) or missed/irregular periods may occur, especially during the first few months of use. If any of these effects last or get worse, tell your doctor or pharmacist promptly. If you miss 2 periods in a row (or 1 period if the pill has not been used properly), contact your doctor for a pregnancy test.

Tell your doctor if you just had or will be having surgery or if you will be confined to a bed or chair for a long time (such as on a long plane flight). These conditions increase your risk of getting blood clots, especially if you are using hormonal birth control. You may need to stop this medication for a time or take special precautions.
This product may increase your potassium levels. Before using potassium supplements or salt substitutes that contain potassium, consult your doctor or pharmacist.
This medication may cause blotchy, dark areas on your skin (melasma). Sunlight may worsen this effect. Avoid prolonged sun exposure, sunlamps, and tanning booths. Use a sunscreen, and wear protective clothing when outdoors.

It may take longer for you to become pregnant after you stop taking birth control pills. Consult your doctor.
This medication must not be used during pregnancy. If you become pregnant or think you may be pregnant, tell your doctor right away. If you have just given birth or had a pregnancy loss/abortion after the first 3 months, talk with your doctor about reliable forms of birth control, and find out when it is safe to start using birth control that contains a form of estrogen, such as this medication.

- atazanavir/cobicistat
- ospemifene
- tamoxifen
- tizanidine
- tranexamic acid

This medication can affect the results of many lab tests. Make sure lab personnel and all your doctors know you use this medication.
