How should I use this medication?
Drospirenone is taken as one tablet daily, at the same time every day. It may be taken with or without food. When you start taking this medication, the first active (white) tablet should be taken on the first day of menstrual bleeding. Take 1 white tablet daily for 24 days, then take 1 green tablet daily for 4 days. Your period should start during this time. After you take the last green pill on day 28, the next day start a new package of pills.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
Many women have spotting or light bleeding or may feel sick to their stomach during the first 3 months of taking the pill. If you do feel sick, do not stop taking the pill. The problem will usually go away. If it does not go away, check with your doctor or clinic.
If you have vomiting or diarrhea, or if you take certain medications (such as antibiotics), your pills may not work as well. If you start a new medication while taking birth control pills, check with your doctor or pharmacist to make sure that it will not reduce the effectiveness of the pills. Use a backup method of birth control, such as latex, until you can check with your doctor or pharmacist.
It is important to take this medication exactly as prescribed by your doctor. If you miss pills at any time, the risk of becoming pregnant increases.
If you miss 1 white pill, take it as soon as you remember, and take the next pill at the usual time. This means that you might take 2 pills in one day. With one missed pill, you do not need to use a back-up birth control method if you have sex.
If you miss 2 or more white pills in a row, take the missed pill as soon as you remember and take the next pill at your regular time. Then take one pill a day until you finish the pack. Use a second method of birth control if you have sex in the 7 days after you miss the pills.
If you miss any of the green pills, safely dispose of the pills you missed and keep taking one pill each day until the pack is empty. Begin a new pack as you would normally.
See package insert for additional information on when to start and what to do if you forget to take a pill, or if you experience vomiting or diarrhea within 3 to 4 hours after taking a pill.
Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Breast cancer: Some studies have suggested the possibility of a link between birth control pills and breast cancer, but nothing conclusive has been found involving this medication. If you are taking birth control pills you should learn how to do a breast self-exam. Notify your doctor of any unusual changes. A yearly clinical breast examination is also recommended.
Cervical cancer: Some studies have suggested the possibility of a link between birth control pills and cervical cancer, but nothing conclusive has been found involving this medication. Women with cervical cancer should not use birth control pills, as the role of female sex hormones in cervical cancer has not been fully determined.
Depression: Women with a history of depression may be more likely to have a recurrence while taking birth control pills. If you have a history of depression or other mental health conditions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Diabetes: Drospirenone may cause slight increases in blood sugar levels (may cause a loss of blood glucose control) and glucose tolerance may change. People with diabetes may find it necessary to monitor their blood sugar more frequently while using this medication.
Irregular menstruation: Irregular menstrual patterns are common among women using progestin-only birth control pills. If you notice changes in your usual menstrual patterns, check with your doctor. If you go a prolonged time without bleeding, you should have a pregnancy test.
Kidney function: Decreased kidney function can cause this medication to build up in the body, causing side effects. If you have a history of decreased kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Laboratory tests: Progestin-only birth control pills may affect how some laboratory tests work. If you are having blood tests to check your thyroid, kidney or liver function, let your doctor know that you are taking drospirenone.
Liver function: This medication may cause changes in liver function. If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Migraine and headache: If you currently suffer from severe headaches or migraines that become more frequent or increase in intensity, or if you develop migraines or headaches that become persistent and bothersome after starting norethindrone, contact your doctor.
Potassium: Drospirenone may increase potassium levels in women who are have a high risk for this condition. Women with reduced adrenal gland, kidney or liver function are at an increased risk.
If you receive other medications that can increase your potassium you should have your potassium levels checked by your doctor when you first start taking this medication. Some of these medications include potassium supplements, angiotensin converting enzyme (ACE) inhibitors, angiotensin-II receptor antagonists, non-steroidal anti-inflammatory drugs (NSAIDs), some diuretics, heparin, and spironolactone.
Regular checkups: While you are taking this medication, have follow-up visits and a physical examination done every year by your doctor.
Sexually transmitted infections (STIs): Birth control pills do not protect against STIs, including HIV/AIDS. For protection against STIs, use latex condoms.
Pregnancy: Birth control pills should not be taken by pregnant women. If you are taking birth control pills and discover that you are pregnant, stop the birth control pills and see your doctor. However, there is no conclusive evidence that the progestin contained in this medication will be harmful to the unborn child.
Breast-feeding: If the use of birth control pills is started after breast-feeding has begun, there does not appear to be any effect on the quantity and quality of the milk. There is no evidence that progestin-only birth control pills such as this medication are harmful to the nursing infant. No side effects have been found on breast-feeding performance or on the health, growth, or development of the infant.
Children: This medication should not be used by adolescent females who have not yet had their first menstrual period.
