Slynd® is a birth control pill (oral contraceptive) also called a POP (progestin only pill) that is used by females who can become pregnant to prevent pregnancy.
Slynd® is effective at preventing pregnancy. Your chance of getting pregnant depends on how well you follow the directions for taking your birth control pills. The better you follow the directions, the less chance you have of getting pregnant. Based on the results of one clinical study of a 28-day regimen of Slynd® about 4 out of 100 females may get pregnant within the first year they use Slynd®.
You should not take Slynd® if you have kidney disease or kidney failure, reduced adrenal gland function (adrenal insufficiency), cervical cancer or any cancer that is sensitive to female hormones, liver disease, including liver tumors or unexplained vaginal bleeding. Tell your healthcare provider if you have or have had any of these conditions. Your health-care provider can suggest a different method of birth control.
Slynd® (white active and green inactive tablets) is swallowed whole once a day. Take one tablet daily for 28 consecutive days; one white active tablet daily during the first 24 days and one green inactive tablet daily during the 4 following days. Tablets must be taken every day at about the same time of the day so that the interval between two tablets is always 24 hours.
If you start taking Slynd® and you are not currently using a hormonal birth control method:
- Start Slynd® on the first day (Day 1) of your natural menstrual period (Day 1 Start). Your healthcare provider should tell you when to start taking your birth control pill.
If you start taking Slynd® and you are switching from another birth control pill:
- Start your new Slynd® blister pack on the same day that you would start the next pack of your previous birth control method.
- Do not continue taking the pills from your previous birth control pack.
If you start taking Slynd® and you are switching from a vaginal ring or transdermal patch:
- Start taking Slynd® on the day you would have inserted the next ring or applied the next patch.
If you start taking Slynd® and you are switching from a progestin only method such as an implant or injection:
- Start taking Slynd® on the day of removal of your implant or on the day when you would have had your next injection.
If you start taking Slynd® and you are switching from an intrauterine device or system (IUD or IUS):
- Start taking Slynd® on the day of removal of your IUD or IUS.
You may stop taking Slynd® whenever you wish. Consider a visit with your healthcare provider for a pre-pregnancy checkup before you stop taking Slynd®.
Slynd® may cause serious side effects, including high potassium levels in your blood (hyperkalemia). Certain medicines and conditions can also increase the potassium levels in your blood. Your healthcare provider may check the potassium levels in your blood before and during treatment with Slynd®.
The most common side effects of Slynd® include acne, menstrual cramps, headache, nausea, breast pain and tenderness, severe vaginal bleeding, weight gain and less sexual desire. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Some women may miss a period. Irregular vaginal bleeding or spotting may happen while you are taking Slynd®, especially during the first few months of use. If the irregular vaginal bleeding or spotting continues or happens again after you have had regular menstrual cycles call your healthcare provider. It is important to continue taking your pills on a regular schedule to prevent a pregnancy.
Some women miss periods on hormonal birth control, even when they are not pregnant. However, if you go 2 or more months in a row without a period, or you miss your period after a month where you did not use all of your Slynd® correctly, call you healthcare provider because you may be pregnant. Also call your healthcare provider if you have symptoms of pregnancy such as morning sickness or unusual breast tenderness. You should stop taking Slynd® if you are pregnant.
If one white active tablet is missed, take the missed tablet as soon as possible. Continue taking one tablet a day until the pack is finished. If two or more white active tablets are missed, take the last missed tablet as soon as possible. Continue one tablet a day until the pack is finished (one or more missed tablet(s) will remain in the blister pack).
