Do not use this medication if you smoke cigarettes/use tobacco and are over 35 years old. Smoking raises your risk of stroke, heart attack, blood clots, and high blood pressure from hormonal birth control (such as the pill, patch, ring). The risk of these serious problems increases with age and with the number of cigarettes you smoke. Do not smoke or use tobacco.
This medication is a combination of 2 hormones: an estrogen (ethinyl estradiol) and a progestin (drospirenone). This product is used to prevent pregnancy.
This medication also may be used to treat premenstrual dysphoric disorder (PMDD) or moderate acne if you have chosen to use birth control pills as your method of pregnancy prevention.
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.
Using this medication does not protect you or your partner against sexually transmitted diseases (such as HIV, gonorrhea, chlamydia).
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 decrease stomach upset and nausea.
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 backup 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 patch, other birth control pills), take the first tablet in the pack on the first Sunday following the beginning of your menstrual period or on the first day of your period. If your period begins on a Sunday, begin taking this medication on that day. For the first cycle of use only, use a backup form of non-hormonal birth control (such as condoms, spermicide) for the first 7 days to prevent pregnancy until the medication has enough time to work. If you start on the first day of your period, you do not need to use backup birth control the first week.
Ask your doctor or pharmacist for information about how to switch from other forms of hormonal birth control (such as the patch, other birth control pills) to this product.
Nausea, vomiting, headache, bloating, breast tenderness, swelling of the ankles/feet (fluid retention), 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, notify your doctor 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.

Drospirenone may raise your potassium blood level. Tell your doctor if you are regularly taking other drugs/products that can also raise your potassium level (including aliskiren, ACE inhibitors such as enalapril/lisinopril, angiotensin receptor blockers such as losartan/valsartan, heparin, NSAIDs such as ibuprofen/naproxen, potassium-sparing "water pills"/diuretics such as eplerenone/spironolactone/triamterene).
Some drugs may cause hormonal birth control to work less well by decreasing the amount of birth control hormones in your body. This effect can result in pregnancy. Examples of these drugs include griseofulvin, modafinil, rifamycins (such as rifampin), ritonavir, St. John's wort, drugs used to treat seizures (such as barbiturates, carbamazepine, felbamate, phenytoin, primidone, topiramate), HIV drugs (such as nelfinavir, nevirapine), among others. Ask your doctor or pharmacist for more details.
Tell your doctor when you start any new drug, and discuss if you should use reliable backup birth control. Also tell your doctor if you have any new spotting or breakthrough bleeding, because these may be signs that your birth control is not working well.
This medication may interfere with certain lab tests, possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
