Mini-Pills
(Progesterone-Only Oral Contraceptives)
What
are Mini-Pills?
Mini-Pills are progesterone-only birth control pills taken in a cycle of once per day for 28 days. They have a synthetic form of the progesterone hormone and no estrogen. The Mini-Pill affects the mucus around the cervix, making it harder for sperm to enter the uterus. It also affects the transport of the egg through the fallopian tubes. In these ways, the Mini-Pill prevents fertilization. Mini-Pills are 87 to 99.7% effective, slightly less than regular birth control pills. They do not protect against sexually transmitted infections (STIs), including HIV/AIDS.

Use
There are hormones in each Mini-Pill;
there are no spacer pills. It is important to take
a pill every day, preferably at the same time each day. Forgetting
a Mini-Pill or taking it late increases the chance of pregnancy more than missing
a regular birth control pill.
You can improve the effectiveness of Mini-Pills by adding a backup method, like condoms or spermicide. This is most important during the first three months, and days eight through eighteen of your menstrual cycle after the first three months.
Starting
Mini-Pills:
Take the first pill on the first day of
your period. Take one pill daily, at the same time of day, even during your period.
After the First
Pack:
As soon as you finish one pack, begin the next
one. Start your next pack even if you are still bleeding or have not started your
period. Continue taking one pill every day.
If
you have problems with the Mini-Pill, call the clinic. DO NOT STOP taking the
Mini-Pills unless you want to get pregnant or can use another method of birth
control.
Missed
Pills
3 or
more hours late: Take a pill as soon as your remember. Use a backup method
for 48 hours.
1 pill missed: Take a pill as
soon as you remember and take the next one at the usual time. This may mean taking
two pills in one day. If you only miss one pill and make it up, you probably will
not get pregnant. Use a backup method for 2 weeks.
2
pills missed: Take 2 pills each day for the next 2 days. Use a backup method
for 2 weeks. You may have some spotting or bleeding. If the bleeding is like a
period, call the clinic.
3 or more pills missed: Use a backup method and call the clinic for instructions.
NEVER
TAKE MORE THAN 2 PILLS IN 1 DAY.
Every woman is different and Mini-Pills are not recommended for all women. Due to the risk of serious health problems, women with unexplained vaginal bleeding, known or suspected pregnancy, or breast cancer should not use Mini-Pills.
Mini-Pills may not be recommended for women who are concerned with weight gain, have liver disease, gallbladder disease, heart disease, diabetes, or a history of depression.
Risks:
Mini-Pills increase the risk of having functional ovarian cysts. They also very slightly increase the risk of ectopic pregnancy. An ectopic pregnancy occurs when a fertilized egg attaches and grows outside the uterus. This can be very dangerous and requires emergency medical attention.

To protect your health, watch out for the Mini-Pill’s “ACHES” danger signs and call a doctor immediately:
- Abdominal
pains (severe)
- Chest
pain or shortness of breath
- Headaches
(severe)
- Eye
problems, such as blurred vision
- Severe
leg or arm pain or numbness
Benefits:
Women on Mini-Pills have a decreased risk of endometrial cancer and pelvic inflammatory disease. They may have less menstrual cramping and pain, fewer periods, and less chance of anemia.
The most common side effect for women using Mini-Pills is irregular bleeding. While many women on Mini-Pills have normal periods, others may have irregular periods, spotting between periods or no periods at all. If you do not bleed for 60 days, call the clinic to arrange for a pregnancy test but continue taking your pills.
Other possible side effects of the Mini-Pill are mood changes, headaches, and lowered sex drive.
Some of the typical side effects of regular birth control pills, such as nausea, and breast tenderness, usually do not occur with Mini-Pills.
Drug
Interactions
The effectiveness of Mini-Pills is lowered when taken with certain medications. These drugs include rifampin and anti-seizure medications. If you are taking any medications, tell your clinician. When taking medications that may interfere with Mini-Pills, consider adding a backup method of birth control, like condoms and spermicide. As with all drugs, it is useful to inform all your medical providers if you are using hormonal birth control.
Women who want to become
pregnant may stop using Mini-Pills at any time. Fertility may return immediately
or after a few months.
