Uses for Junel 1/20
Ethinyl estradiol and norethindrone combination is used to prevent pregnancy. It is a birth control pill that includes two hormones, ethinyl estradiol and norethindrone, and when taken correctly, it prevents pregnancy. It works by stopping a woman's egg from fully developing each month. The egg cannot accept sperm, so fertilization (pregnancy) is prevented.
No contraceptive method is 100 percent effective. Other birth control methods, like surgery to become sterile or abstaining from sex, are more effective than birth control pills. Talk to your doctor about your birth control options.
This medicine does not prevent HIV infection or other sexually transmitted diseases. It will not work as emergency contraception, such as after unprotected sexual contact.
This medicine is available only with your doctor's prescription.

Precautions while using Junel 1/20
It is very important for your doctor to check how you are doing at regular visits to ensure that this medicine is working properly and not causing unwanted effects. These visits will usually be every 6 to 12 months, but some doctors may want to see you more often. Your doctor may also want to check your blood pressure while you are taking this medicine.
Even though you are using this medicine to prevent pregnancy, you should know that using it while pregnant could harm the unborn baby. If you think you might be pregnant while using this medicine, tell your doctor right away. Make sure your doctor knows if you had given birth within 4 weeks before starting this medicine.
Do not use this medicine with any medicine for treating hepatitis C virus infection, including ombitasvir/paritaprevir/ritonavir, with or without dasabuvir (Technivie®, Viekira Pak®).
You may experience vaginal bleeding of various amounts between your regular menstrual periods during the first 3 months of use. This can be called spotting when it is light, or breakthrough bleeding when it is heavier.
- If this happens, continue with your regular dosing schedule.
- The bleeding usually stops within 1 week. Contact your doctor if the bleeding continues for more than 1 week.
- If the bleeding continues after taking hormonal contraceptives on schedule for more than 3 months, consult your doctor.
Contact your doctor immediately if you miss a menstrual period. Missed periods may occur if you skip one or more tablets and have not taken your pills exactly as directed. If you miss two periods in a row, call your doctor for a pregnancy test before taking any more pills.
If you think you may be pregnant, check with your doctor right away.
Do not use this medicine if you smoke cigarettes or if you are over 35 years old. Smoking while using norethindrone and ethinyl estradiol combination increases your risk of blood clots, heart attack, or stroke. Your risk is even higher if you are over age 35, have diabetes, high blood pressure, high cholesterol, or are overweight. Discuss ways to stop smoking with your doctor. Keep your diabetes under control. Ask your doctor about diet and exercise to manage your weight and blood cholesterol levels.
Using this medicine may raise your risk of blood clotting problems. Contact your doctor immediately if you have chest pain, groin pain, or leg pain, especially in the calves, difficulty breathing, a sudden severe headache, slurred speech, sudden unexplained shortness of breath, sudden loss of coordination, or changes in vision while using this medicine.
Using this medicine may increase your risk of breast cancer or cancers of your reproductive organs (such as endometrial, ovarian, or cervical cancer). Discuss this risk with your doctor. Contact your doctor immediately if you experience abnormal vaginal bleeding.
Contact your doctor right away if you wear contact lenses or if you have blurred vision, trouble reading, or any other changes in vision during or after treatment. Your doctor may refer you to an eye doctor (ophthalmologist) for an examination.
Contact your doctor immediately if you have pain or tenderness in your upper stomach, dark urine, pale stools, or yellowing of your eyes or skin. These could be signs of a serious liver problem.
This medicine may increase your risk of gallbladder disease. Contact your doctor if you start having stomach pains, nausea, or vomiting.
Check with your doctor before refilling an old prescription, especially after a pregnancy. You will need another physical examination, and your doctor may change your prescription.
Make sure any doctor or dentist who treats you knows that you are using this medicine. Some medical tests may be affected by this medicine. You may also need to stop using this medicine at least 4 weeks before and 2 weeks after major surgery.
Do not take other medicines unless your doctor has discussed them with you. This includes prescription or nonprescription (over-the-counter [OTC]) medicines as well as herbal (e.g., St. John's wort) or vitamin supplements.
