    • What is this medication and its most common uses?

      Quasense is a birth control pill used to prevent pregnancy.

    • What should I know when beginning and continuing on this medication?

      Birth control pills do not protect against transmission of HIV (AIDS) and other sexually transmitted diseases such as Chlamydia, genital herpes, genital warts, gonorrhea, hepatitis B, and syphilis.

      How does this medication work?

      Quasense delivers hormones to block ovulation. If ovulation does not occur, your egg is not released, thereby preventing you from becoming pregnant. Quasense also changes the mucus in the cervix, making it difficult for sperm to enter the uterus as well as changes the endometrium.

      What are the beneficial effects of this medication and when should I begin to have results?

      What: Quasense delivers hormones to block ovulation. If ovulation does not occur, your egg is not released, thereby preventing you from becoming pregnant. Quasense also changes the mucus in the cervix, making it difficult for sperm to enter the uterus as well as changes the endometrium.

      When: It may take 7 days for the pills to take effect in preventing pregnancy and you should therefore use another method of birth control as a back-up method during this time.  

      How do I know it is working?

      If you are taking the pill as directed by your healthcare provider and not missing any doses, you should be protected from becoming pregnant.

    • What are the possible side effects of this medication?

      The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.

      Cigarette smoking increases the risk of serious heart-related side effects from use of birth control pills. This risk increases with age and the number of cigarettes you smoke. Do not smoke while you are taking birth control pills. 

      More common side effects may include: nausea, vomiting, bleeding or spotting between menstrual periods, weight gain, breast tenderness, and difficulty wearing contact lenses.

      Less common side effects may include:

      Blood clots in your legs, lungs, or eyes, with symptoms such as sharp chest pain, coughing up blood, sudden shortness of breath, pain in your calf, or sudden partial or complete loss of vision.

      Stroke, angina (chest pain), or a heart attack, with symptoms such as crushing chest pain or heaviness in your chest, sudden severe headache or vomiting, dizziness or fainting, changes in your vision or speech, weakness, or numbness in an arm or leg. Smoking greatly increases the possibility of suffering a heart attack or stroke.

      Noncancerous but dangerous liver tumors or other liver problems, with symptoms such as severe pain or tenderness in your stomach area, or yellowing of your skin or the whites of your eyes, often accompanied by fever, fatigue, loss of appetite, dark colored urine, or light colored bowel movements.

      Increased risk of developing breast cancer, especially after using hormonal birth control at a younger age. After you stop using hormonal birth control, the chances of developing breast cancer begin to go back down. Examine your breasts monthly and call your healthcare provider if you feel a lump

      Birth control pills may also cause fluid retention with swelling of your fingers or ankles, increased blood pressure, increased triglyceride levels (fats in the blood), or increased risk of developing gallbladder disease.

    • Who should not take this medication?

      Do not take Quasense if you are allergic to it or any of its ingredients.

      Do not take Quasense if you have a history of heart attack or stroke; heart disease; blood clots in your legs, lungs, or eyes; high blood pressure uncontrolled by medication; diabetes with kidney, eye, nerve, or blood vessel damage; certain types of headaches; breast cancer or cancer of the lining of the uterus, cervix, or vagina; unexplained vaginal bleeding (until a diagnosis is reached by your healthcare provider); yellowing of your skin or the whites of your eyes during pregnancy or during previous use of birth control pills; or liver tumors or active liver disease.

      Do not take Quasense if you are scheduled for surgery and plan to be on bed rest for a long time.

      Do not take Quasense if you are or think you may be pregnant.

    • What should I tell my healthcare provider before I take the first dose of this medication?

      Tell your healthcare provider about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Quasense. Tell your healthcare provider if you have ever had any of the health conditions listed above. Also, talk to your healthcare provider about your complete medical history, especially if you have or have had breast nodules; fibrocystic disease of the breast (lumpy and painful breasts); an abnormal breast x-ray or mammogram; diabetes; high cholesterol or triglycerides; high blood pressure; migraines or other headaches; seizures; depression; gallbladder, liver, heart, or kidney disease; irregular menstrual periods; or if you wear contact lenses.

    • What is the usual dosage?

      The information below is based on the dosage guidelines your healthcare provider uses. Depending on your condition and medical history, your healthcare provider may prescribe a different regimen. Do not change the dosage or stop taking your medication without your healthcare provider's approval.

      Women and adolescents who have had their first menstrual period: There are 84 white "active" pills and 7 peach "reminder" pills.

      Sunday Start: Take the first white "active" pill on the Sunday after your period begins, even if you are still bleeding. If your period begins on Sunday, start the first white "active" pill that same day. Take one white pill for 84 days, followed by one peach "reminder" pill for 7 days. After all 91 pills have been taken; start a new course the next day (Sunday).

    • How should I take this medication?

      Before you start taking Quasense, be sure to read the directions. Take one pill at the same time every day until the pack is empty.

      Use another method of birth control (such as condoms or spermicides) as a back-up method if you have sex any time from the Sunday you start your first white "active" pill until the next Sunday (first 7 days).

      When you finish a pack, start the next pack on the day after your last peach "reminder" pill. Do not wait any days between packs. If you are switching from another brand of pills, start Quasense on the same day that a new pack of the previous pills should have been started. If you are switching from another birth control method, talk to your healthcare provider about what you should do.

      If you have vomiting or diarrhea after you take Quasense, it may not work as well. Use another birth control method (such as condoms or a spermicide) until you check with your healthcare provider.

      Irregular vaginal bleeding or spotting may occur while you are taking the pills. Irregular bleeding may vary from slight staining between menstrual periods to breakthrough bleeding, which is a flow much like a regular period. Irregular bleeding occurs most often during the first few months of taking the pills, but may also occur after you have been taking the pill for some time. Such bleeding may be temporary and usually does not indicate any serious problems. It is important to continue taking your pills on schedule. Tell your healthcare provider if the bleeding occurs in more than one cycle or lasts for more than a few days.

      There may be times when you may not have regular menstrual periods after you have completed taking a cycle of pills. If you have taken your pills regularly and miss one menstrual period, continue taking your pills for the next cycle, but be sure to inform your healthcare provider. If you have not taken the pills daily as instructed and missed a menstrual period, or if you missed two consecutive menstrual periods, you may be pregnant.

    • What should I avoid while taking this medication?

      Do not smoke cigarettes while you are taking Quasense.

      Do not skip pills, even if you are spotting or bleeding between monthly periods, feel sick to your stomach (nausea), or if you do not have sex very often.

    • What are the possible food and drug interactions associated with this medication?

      If Quasense is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Quasense may interact with numerous medications. Therefore, it is very important that you tell your healthcare provider about any other medications you are taking.

    • May I receive this medication if I am pregnant or breastfeeding?

      Do not take Quasense if you are pregnant or breastfeeding. Quasense can be found in your breast milk if you take it while breastfeeding. Tell your healthcare provider immediately if you are pregnant, plan to become pregnant, or are breastfeeding.

    • What should I do if I miss a dose of this medication?

      If you miss one white "active" pill, take it as soon as you remember. Take the next pill at your regular time. This means you can take two pills in the same day. You do not need a back-up birth control method if you have sex.

      If you miss two or more white "active" pills, consult the patient information that accompanied your prescription or call your healthcare provider or pharmacist for advice.

      If you miss any of the 7 peach "reminder" pills, throw away the missed pills. Keep taking the scheduled pills until the pack is finished. You do not need a back-up method of birth control.
