Uses for Loryna

Drospirenone and ethinyl estradiol combination is used to prevent pregnancy. It is a birth control pill that contains two hormones, ethinyl estradiol and drospirenone, 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, which prevents fertilization (pregnancy).

This medicine is also used to treat premenstrual dysphoric disorder (PMDD) and acne in women who are at least 14 years old. PMDD is a severe type of premenstrual syndrome (PMS). Patients with PMDD may experience severe emotional and physical symptoms 10 to 14 days before their menstrual period starts.

No contraceptive method is 100 percent effective. Other birth control methods, such as surgical sterilization or abstaining from sex, are more effective than birth control pills. Talk with your doctor about your birth control options.

This medicine does not prevent AIDS or other sexually transmitted diseases. It will not work as emergency contraception after unprotected sexual contact.

This medicine is available only with your doctor's prescription.

Precautions while using Loryna

It is very important for your doctor to check your progress at regular visits to ensure this medicine is working properly and does not cause unwanted effects. These visits will usually be every 6 to 12 months, but some doctors may require them 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 this medicine while you are pregnant could harm the unborn baby. If you think you have become pregnant while using the medicine, tell your doctor right away. Make sure your doctor knows if you had a baby within 4 weeks before you start using this medicine.

Do not use this medicine together with medicine to treat hepatitis C virus infection, including ombitasvir/paritaprevir/ritonavir, with or without dasabuvir (Technivie®, Viekira Pak®).

Vaginal bleeding of different amounts may occur between your regular menstrual periods during the first 3 months of use. This is sometimes called spotting when it is slight, or breakthrough bleeding when it is heavier.

  • If this occurs, continue with your regular dosing schedule.
  • The bleeding usually stops within 1 week. Check with your doctor if the bleeding continues for more than 1 week.
  • If the bleeding continues after you have been taking hormonal contraceptives on schedule and for more than 3 months, check with your doctor.

Check with your doctor right away if you miss a menstrual period. Missed periods may happen if you skip one or more tablets and have not taken your pills exactly as directed. If you miss two periods in a row, talk to your doctor. You might need a pregnancy test.

If you suspect that you may be pregnant, check with your doctor immediately.

Do not use this medicine if you smoke cigarettes or if you are over 35 years of age. If you smoke while using birth control pills containing drospirenone, you increase your risk of having a blood clot, heart attack, or stroke. Your risk is even higher if you are over age 35, if you have diabetes, high blood pressure, high cholesterol, or if you are overweight. Talk with your doctor about ways to stop smoking. Keep your diabetes under control. Ask your doctor about diet and exercise to control your weight and blood cholesterol level.

Using this medicine may increase your risk of having blood clotting problems, especially in the first 6 months of use. This risk may be higher if you are using a birth control pill containing drospirenone and ethinyl estradiol. Check with your doctor right away if you have pain in the chest, groin, or legs, especially the calves, difficulty breathing, a sudden, severe headache, slurred speech, sudden unexplained trouble breathing, sudden loss of coordination, or vision changes while using this medicine.

Check with your doctor immediately if you wear contact lenses or if you experience blurred vision, difficulty reading, or any other change in vision during or after treatment. Your doctor may want an eye doctor to check your eyes.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, unusual tiredness or weakness, or yellow eyes or skin. These could be symptoms of a serious liver problem.

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. The results of 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 having major surgery.

This medicine may cause skin discoloration. Use a sunscreen when you are outdoors. Avoid sunlamps and tanning beds.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (e.g., St. John's wort) or vitamin supplements.
