Contraceptive 28 Day Progestin-only Pill Pack

What It's For & How To Take

The 28 day progestin-only pill pack is hormonal contraceptive birth control. If you are using this medication for a reason other than birth control, please talk about it with your doctor.

Progestin-only hormone therapy prevents pregnancy by changing the environment in the womb. This medication makes it difficult for the sperm to fertilize an egg, or for a fertilized egg to attach to the wall of the womb.

Progestin-only therapy is more effective birth control than condoms or diaphragms; however, it is not as effective as estrogen/progestin combination therapy because it does not consistently prevent ovulation. This therapy is usually taken by women who are unable to take estrogens for one reason or another.

Unless directed differently by your doctor, take your first dose of this medication on the first day of your cycle. When starting this medication, you will need to use a backup form of birth control for the first 2 days. Missing a dose is considered going only 3 hours after your normal dose time without taking a pill.

If you miss your normal dose time by more than 3 hours, take it as soon as you remember and continue with your normal schedule. If you vomit or have diarrhea within 4 hours of taking your dose, consider that a missed dose. You must use a backup form of birth control such as condom or spermicide with any sex you have over the next two days. Contact your health care provider and discuss the option of emergency contraception if you had unprotected sex during the missed dose time frame.

Find your medication package paperwork and locate the exact instructions that explain what to do when you miss a dose. Cut out this section and put it in your wallet. Ask your doctor or pharmacist to explain these instructions if you do not understand them.

While taking this medication, if you miss your period for 2 months in a row, call your doctor.

Warnings & Cautions

  • Do not use birth control pills if you are pregnant, might be pregnant, or are breastfeeding. If you are taking this medication and think you might be pregnant, talk with your doctor right away.
  • When starting this therapy, use an additional form of birth control such as a condom or spermicide for the first 48 hours while the medication is building up in your system.
  • If you are ever unsure what to do about the pills you have missed, use a back-up contraception method, such as a condom or spermicidal gel, anytime you have sex.
