Precautions

Before taking drospirenone, tell your doctor or pharmacist if you are allergic to it; or to any progestins (such as norethindrone, desogestrel); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: adrenal gland problems, abnormal breast exam, cancer (especially endometrial or breast cancer), depression, diabetes, severe headaches/migraines, history of yellowing eyes/skin (jaundice) during pregnancy or while using hormonal birth control (such as pills, patch), kidney disease, liver disease (including tumors), swelling (edema), unexplained vaginal bleeding.

If you have diabetes, this medication may affect your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. Your doctor may need to adjust your diabetes medication, exercise program, or diet.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

This product may increase your potassium levels. Before using potassium supplements or salt substitutes that contain potassium, consult your doctor or pharmacist.

This medication may cause blotchy, dark areas on your skin (melasma). Sunlight may worsen this effect. Avoid prolonged sun exposure, sunlamps, and tanning booths. Use a sunscreen, and wear protective clothing when outdoors.

It may take longer for you to become pregnant after you stop taking birth control pills. Consult your doctor.

This medication should not be used during pregnancy. If you become pregnant or think you may be pregnant, tell your doctor right away. If you have just given birth or had a pregnancy loss or abortion after the first 3 months, talk with your doctor about reliable forms of birth control, and find out when it is safe to start using birth control.

This medication passes into breast milk in very small amounts but is unlikely to harm a nursing infant. Consult your doctor before breastfeeding.

Side Effects

Nausea, vomiting, headache, bloating, breast tenderness, acne, or weight gain may occur. Vaginal bleeding between periods (spotting) or missed/irregular periods may occur, especially during the first few months of use. If any of these effects last or get worse, tell your doctor or pharmacist promptly. If you miss 2 periods in a row (or 1 period if the pill has not been used properly), contact your doctor for a pregnancy test.

Remember that this medication has been prescribed because your doctor 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 right away if you have any serious side effects, including: lumps in the breast, mental/mood changes (such as new/worsening depression), severe stomach/abdominal pain, symptoms of a high potassium blood level (such as muscle weakness, slow/irregular heartbeat), unusual changes in vaginal bleeding (such as continuous spotting, sudden heavy bleeding, missed periods), dark urine, yellowing eyes/skin.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
