Orsythia is a combination birth control pill containing female hormones that prevent ovulation (the release of an egg from an ovary). Orsythia also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
Orsythia is used as contraception to prevent pregnancy. There are many brands and forms of this medicine available.
Take your first pill on the first day of your period or on the first Sunday after your period begins. You may need to use back-up birth control, such as condoms or a spermicide, when you first start using this medicine. Follow your doctors instructions.
Take one pill every day, no more than 24 hours apart. When the pills run out, start a new pack the following day. You may get pregnant if you do not take one pill daily. Get your prescription refilled before you run out of pills completely.
Some birth control packs contain seven "reminder" pills to keep you on your regular cycle. Your period will usually begin while you are using these reminder pills.
Use a back-up birth control if you are sick with severe vomiting or diarrhea.
You may have breakthrough bleeding, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.
If you need major surgery or will be on long-term bed rest, you may need to stop using this medicine for a short time. Any doctor or surgeon who treats you should know that you are using birth control pills.
While taking birth control pills, you will need to visit your doctor regularly.
Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Stop using birth control pills and call your doctor at once if you have:
signs of a stroke--sudden numbness or weakness (especially on one side of the body), severe headache, slurred speech, balance problems;
signs of a blood clot--sudden vision loss, stabbing chest pain, feeling short of breath, coughing up blood, swelling or redness in an arm or leg;
heart attack symptoms--chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating;
liver problems--loss of appetite, upper stomach pain, tiredness, fever, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
increased blood pressure--severe headache, blurred vision, pounding in your neck or ears;
swelling in your hands, ankles, or feet;
changes in the pattern or severity of migraine headaches;
a breast lump; or
symptoms of depression--sleep problems, weakness, tired feeling, mood changes.
Common side effects may include:

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Store this medicine at room temperature away from moisture and heat.
Some products that may interact with this drug include: aromatase inhibitors (such as anastrozole, exemestane), ospemifene, tamoxifen, tizanidine, tranexamic acid, certain combination products used to treat chronic hepatitis C (ombitasvir/paritaprevir/ritonavir with or without dasabuvir).
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. Johns 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 medication may interfere with certain laboratory tests (such as blood clotting factors, thyroid), possibly causing false test results. Make sure laboratory personnel and all your doctors know you use this medication.
