Drospirenone is a progestin-only birth control pill that is used to prevent pregnancy.

Drospirenone may also be used for purposes not listed in this medication guide.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Drospirenone comes in a pack of pills that are different colors. Take a white (active) pill every day for 24 days in a row, and then take a green (inactive) pill for the next 4 days in a row. Then start a new pack and repeat this daily cycle.

Take your first pill on the first day of your period. If you are switching to drospirenone from another form of birth control, follow the Instructions for Use about when you start taking drospirenone.

Each time you start a new pack, start with the first tablet in the first row of pills. Your medicine may come with stickers to mark your weekday schedule on the pack.

Take drospirenone at the same time each day.

Swallow the tablet whole and do not crush, chew, or break it.

You may need to use back-up birth control, such as condoms with spermicide, when you first start using drospirenone.

If you vomit or have diarrhea within 3 to 4 hours after taking drospirenone, take your next daily tablet as soon as possible or within 12 hours of the usual time you take your pill. Then keep taking 1 pill every day in order at the usual time.

You may have breakthrough bleeding, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using drospirenone.

If you miss a period, call your doctor because you might be pregnant.

If you miss an inactive pill, skip the missed pill(s) and keep keep taking 1 inactive pill per day until the pack is empty.
