Progestin-Only (drospirenone) Oral Contraceptives

pronounced as (pro jes' tin)

Brand Name(s): Slynd®

Why is this medicine prescribed?

Progestin-only (drospirenone) oral contraceptives are used to prevent pregnancy. Progestin is a female hormone. It works by preventing the release of eggs from the ovaries (ovulation) and changing the cervical mucus and the lining of the uterus. Progestin-only oral contraceptives are a very effective method of birth control, but they do not prevent the spread of of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.

Are there other uses for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

Progestin-only (drospirenone) oral contraceptives come as tablets to take by mouth once a day. Take oral contraceptives at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take your oral contraceptive exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Progestin-only (drospirenone) oral contraceptives come in packs of 28 tablets that have 2 different colors. Take 1 tablet daily for 28 days in a row in the order specified in your packet. The first 24 tablets are white and contain the active ingredient (drospirenone). The last 4 tablets are green and contain an inactive ingredient. Start a new packet the day after you take your 28th tablet.

Your doctor will tell you when you should start taking your progestin-only (drospirenone) oral contraceptive. Tell your doctor if you are switching from another type of contraception (other birth control pills, vaginal ring, transdermal patch, implant, injection, intrauterine device [IUD]).

If you vomit or have diarrhea within 3 or 4 hours after taking a white tablet (containing the active ingredient), take the next tablet in your packet as soon as possible (preferably within 12 hours of the dose previously taken). Continue your regular dosing schedule and finish your current packet. When you start a new packet, it will be one day earlier than your previous schedule. You may need to use a backup method of birth control if you vomit or have diarrhea for more than 1 day while you are taking the white tablets (containing the active ingredient). Talk to your doctor about this before you begin to take your oral contraceptive so that you can prepare a backup method of birth control in case it is needed. If you vomit or have diarrhea while you are taking an oral contraceptive, call your doctor to find out how long you should use the backup method.

Oral contraceptives will work only as long as they are taken regularly. Continue to take oral contraceptives every day even if you are spotting or bleeding, have an upset stomach, or do not think that you are likely to become pregnant. Do not stop taking oral contraceptives without talking to your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

What should I know about storage and disposal of this medication?

Keep this medication in the packet it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( ) for more information if you do not have access to a take-back program.

Before you have any laboratory tests, tell the laboratory personnel that you take progestin-only (drospirenone) oral contraceptive, as this medication may interfere with some laboratory tests.

You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
