LEVONORGESTREL/ETHINYL ESTRADIOL EXTENDED CYCLE ORAL CONTRACEPTIVE
COMMON BRAND NAME(S): Seasonale
WARNING: Smoking cigarettes/using tobacco while using hormonal birth control (pill/patch/ring) increases your risk of heart problems and stroke. Do not smoke. The risk of heart problems increases with age (especially in women over 35) and with frequent smoking (15 or more cigarettes a day).
USES: This medication is a combination of 2 hormones (an estrogen and a progestin) and is used to prevent pregnancy. It works mainly by preventing the release of an egg (ovulation) during your menstrual cycle. It also can work by making vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and by changing the lining of the uterus (womb) to prevent attachment of a fertilized egg. If a fertilized egg does not attach to the uterus, it passes out of the body. Besides preventing pregnancy, birth control pills have been shown to help make your periods more regular, decrease blood loss and painful periods (dysmenorrhea), and decrease your risk of ovarian cysts. Using this medication does not protect you or your partner against sexually transmitted diseases (e.g., HIV, gonorrhea).
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 about when to take your pills and what to do if you miss a dose. If you have any questions, consult your doctor or pharmacist. Take this medication by mouth once daily or as directed by your doctor. Pick a time of day that is easy for you to remember, and take your pill at the same time each day. Begin taking this medication on the first Sunday following the beginning of your period (menstruation). If your period begins on a Sunday, begin taking this medication on that day. The 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 pill, take the first active pill in a new pack to start a new cycle. It is very important to continue taking this medication exactly as prescribed by your doctor. Take the pills 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. If you have any stomach upset or nausea with this medication, it may help to take it after your evening meal or at bedtime. 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. If this is the first time you are using this medication and you are not switching from another form of hormonal birth control (e.g., patch, other birth control pills), use an additional form of non-hormonal birth control (e.g., condoms, spermicide) for the first 7 days to prevent pregnancy until the medication has enough time to work. If you take all the pills correctly, you will only need to use a back-up method for the first week of the first cycle. Ask your doctor or pharmacist for information about how to switch from other forms of hormonal birth control (e.g., patch, other birth control pills) to this product. If any of this information is unclear, consult the Patient Information Leaflet or your doctor or pharmacist.
SIDE EFFECTS: Nausea, vomiting, headache, stomach cramping/bloating, dizziness, vaginal discomfort/irritation, increased vaginal fluids, or breast tenderness/enlargement may occur. Acne may improve or get worse. Vaginal bleeding between periods (spotting) may occur, especially during the first few months of use. If any of these effects persist or worsen, tell your doctor 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. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor immediately if any of these serious side effects occur: changes in vaginal bleeding (e.g., continuous spotting, sudden heavy bleeding, missed periods while taking the inactive pills), problem wearing contact lenses, dark patches on the skin (melasma), unwanted facial/body hair, swelling of the ankles/feet, weight changes (gain or loss). This medication may rarely cause serious (sometimes fatal) problems from blood clots (e.g., pulmonary embolism, stroke, heart attack). Seek immediate medical attention if you experience: sudden shortness of breath, chest/jaw/left arm pain, confusion, coughing up blood, sudden dizziness/fainting, pain/swelling/warmth in the groin/calf, tingling/weakness/numbness in the arms/legs, headaches that are different from those you may have experienced in the past (e.g., headaches with other symptoms such as vision changes/lack of coordination, existing migraines becoming worse, sudden/very severe headaches), slurred speech, weakness on one side of the body, vision problems/changes. Tell your doctor immediately if any of these rare but very serious side effects occur: lumps in the breast, severe stomach/abdominal/pelvic pain, mental/mood changes (e.g., depression, suicidal thoughts, persistent trouble sleeping), unusual tiredness, dark urine, yellowing eyes/skin. A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing. This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

DRUG INTERACTIONS: The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring. To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval. Some products that may interact with this drug include: aromatase inhibitors (e.g., anastrazole, exemestane), raloxifene, sodium tetradecyl sulfate, tamoxifen, medication for underactive thyroid (hypothyroidism), drugs that may increase blood levels of this drug (such as acetaminophen, vitamin C, atorvastatin, azole antifungals such as itraconazole/ketoconazole/vaginal miconazole). 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 include griseofulvin, modafinil, rifamycins (such as rifampin, rifabutin), St. John's wort, drugs used to treat seizures (such as barbiturates, carbamazepine, felbamate, phenytoin, primidone, topiramate), HIV drugs (such as nelfinavir, nevirapine, ritonavir), among others. Tell your doctor when you start any new drug, and discuss if you should use additional reliable 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 drug can speed up or slow down the removal of other drugs from your body by affecting certain liver enzymes. These affected drugs include acetaminophen, certain beta blockers (e.g., metoprolol), clofibrate, cyclosporine, morphine, corticosteroids such as prednisolone, certain benzodiazepines such as lorazepam/temazepam, theophylline, and tizanidine, among others. If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting this medication. This medication can affect the results of certain lab tests (e.g., blood tests for clotting factors, thyroid). Make sure laboratory personnel and all your doctors know you use this medication.
