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, 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.

It is very important to keep taking this medication exactly as prescribed by your doctor. 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.

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. Ask your doctor or pharmacist if you have any questions.

Begin taking this medication on the first Sunday following the beginning of your menstrual period. If your period begins on a Sunday, begin taking this medication on that day. Your pill pack contains 84 active pills (with hormones) and 7 inactive pills (without hormones). Take one active pill daily for 84 days in a row. The day after you finish all the active pills, start taking one inactive pill daily for 7 days in a row. You should have your period during the week you are taking the inactive pills. The day after you take the last inactive tablet in the pack, start a new pack 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, 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 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.

Nausea, vomiting, headache, bloating, breast tenderness, swelling of the ankles/feet (fluid retention), or weight change may occur. Vaginal bleeding between periods (spotting) 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.

You should not have your period during the 3 months that you are taking the active pills. Instead, you will have your period once every 3 months, during the week that you are taking the inactive pills. This effect is normal with this product. However, if you do not have your period while taking the inactive pills, contact your doctor for a pregnancy test.
