Patient information: uses, side effects, how to take - Femynor

What is the most important information I should know about Femynor ?

Do not use Femynor if you smoke cigarettes and are over 35 years old. Smoking increases your risk of serious cardiovascular side effects from hormonal birth control pills, including death from heart attack, blood clots or stroke. This risk increases with age and the number of cigarettes you smoke.

What is Femynor ?

Femynor is a birth control pill (oral contraceptive) used by women to prevent pregnancy.

How does Femynor work for contraception?

Your chance of getting pregnant depends on how well you follow the directions for taking your birth control pills. The better you follow the directions, the less chance you have of getting pregnant.

Based on the results of clinical studies, about 1 out of 100 women may get pregnant during the first year they use Femynor.

The following chart shows the chance of getting pregnant for women who use different methods of birth control. Each box on the chart contains a list of birth control methods that are similar in effectiveness. The most effective methods are at the top of the chart. The box on the bottom of the chart shows the chance of getting pregnant for women who do not use birth control and are trying to get pregnant.

Who should not take Femynor ?

Do not take Femynor if you:

  • smoke and are over 35 years of age
  • had blood clots in your arms, legs, lungs, or eyes
  • had a problem with your blood that makes it clot more than normal
  • have certain heart valve problems or irregular heart beat that increases your risk of having blood clots
  • had a stroke
  • had a heart attack
  • have high blood pressure that cannot be controlled by medicine
  • have diabetes with kidney, eye, nerve, or blood vessel damage
  • have certain kinds of severe migraine headaches with aura, numbness, weakness or changes in vision, or any migraine headaches if you are over 35 years of age
  • have liver problems, including liver tumors
  • have any unexplained vaginal bleeding
  • are pregnant
  • had breast cancer or any cancer that is sensitive to female hormones

If any of these conditions happen while you are taking Femynor , stop taking Femynor right away and talk to your healthcare provider. Use non-hormonal contraception when you stop taking Femynor .

What should I tell my healthcare provider before taking Femynor ?

Tell your healthcare provider if you:

  • are pregnant or think you may be pregnant
  • are depressed now or have been depressed in the past
  • had yellowing of your skin or eyes (jaundice) caused by pregnancy (cholestasis of pregnancy)
  • are breastfeeding or plan to breastfeed. Femynor may decrease the amount of breast milk you make. A small amount of the hormones in Femynor may pass into your breast milk. Talk to your healthcare provider about the best birth control method for you while breastfeeding.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins and herbal supplements.

Femynor may affect the way other medicines work, and other medicines may affect how well Femynor works.

Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

What are the possible serious side effects of Femynor ?

  • Like pregnancy, Femynor may cause serious side effects, including blood clots in your lungs, heart attack, or a stroke that may lead to death. Some other examples of serious blood clots include blood clots in the legs or eyes.

Serious blood clots can happen especially if you smoke, are obese, or are older than 35 years of age. Serious blood clots are more likely to happen when you:

  • first start taking birth control pills
  • restart the same or different birth control pills after not using them for a month or more

Call your healthcare provider or go to a hospital emergency room right away if you have:

  • leg pain that will not go away
  • sudden severe shortness of breath
  • sudden change in vision or blindness

Call your healthcare provider if you have a swollen face, lips, mouth tongue or throat, which may lead to difficulty swallowing or breathing. Your chance of having angioedema is higher is you have a history of angioedema.
  • dark patches of skin around your forehead, nose, cheeks and around your mouth, especially during pregnancy (chloasma). Women who tend to get chloasma should avoid spending a long time in sunlight, tanning booths, and under sun lamps while taking Femynor. Use sunscreen if you have to be in the sunlight.

Do birth control pills cause cancer?

Birth control pills do not seem to cause breast cancer. However, if you have breast cancer now, or have had it in the past, do not use birth control pills because some breast cancers are sensitive to hormones.

Women who use birth control pills may have a slightly higher chance of getting cervical cancer. However, this may be due to other reasons such as having more sexual partners.

What if I want to become pregnant?

You may stop taking the pill whenever you wish. Consider a visit with your healthcare provider for a pre-pregnancy checkup before you stop taking the pill.

What should I know about my period when taking Femynor ?

Your periods may be lighter and shorter than usual. Some women may miss a period. Irregular vaginal bleeding or spotting may happen while you are taking Femynor, especially during the first few months of use. This usually is not a serious problem. It is important to continue taking your pills on a regular schedule to prevent a pregnancy.

Instructions For Use

FEMYNOR™ (feh’ mi nore)

(norgestimate and ethinyl estradiol tablets, USP)

Important Information about taking Femynor

  • Take 1 pill every day at the same time. Take the pills in the order directed on your blister pack.
  • Do not skip your pills, even if you do not have sex often. If you miss pills (including starting the pack late) you could get pregnant. The more pills you miss, the more likely you are to get pregnant.
  • If you have trouble remembering to take Femynor, talk to your healthcare provider. When you first start taking Femynor, spotting or light bleeding in between your periods may occur. Contact your healthcare provider if this does not go away after a few months.
  • You may feel sick to your stomach (nauseous), especially during the first few months of taking Femynor. If you feel sick to your stomach, do not stop taking the pill. The problem will usually go away. If your nausea does not go away, call your healthcare provider.
  • Missing pills can also cause spotting or light bleeding, even when you take the missed pills later. On the days you take 2 pills to make up for missed pills (see What should I do if I miss any Femynor pills? below), you could also feel a little sick to your stomach.
  • It is not uncommon to miss a period. However, if you miss a period and have not taken Femynor according to directions, or miss 2 periods in a row, or feel like you may be pregnant, call your healthcare provider. If you have a positive pregnancy test, you should stop taking Femynor.
  • If you have vomiting or diarrhea within 3 to 4 hours of taking your pill, take another pill of the same color from your extra blister pack. If you do not have an extra blister pack, take the next pill in your blister pack. Continue taking all your remaining pills in order. Start the first pill of your next blister pack the day after finishing your current blister pack. This will be 1 day earlier than originally scheduled. Continue on your new schedule.
  • If you have vomiting or diarrhea for more than 1 day, your birth control pills may not work as well. Use an additional birth control method, like condoms and a spermicide, until you check with your healthcare provider.
  • Stop taking Femynor at least 4 weeks before you have major surgery and do not restart after the surgery without asking your healthcare provider. Be sure to use other forms of contraception (like condoms and spermicide) during this time period.

Before you start taking Femynor :

  • Decide what time of day you want to take your pill. It is important to take it at the same time every day and in the order as directed on your blister pack.
  • Have backup contraception (condoms and spermicide) available and if possible, an extra full pack of pills as needed.

When should I start taking Femynor ?

If you start taking Femynor and you have not used a hormonal birth control method before:

  • There are 2 ways to start taking your birth control pills. You can either start on a Sunday (Sunday Start) or on the first day (Day 1) of your natural menstrual period (Day 1 Start). Your healthcare provider should tell you when to start taking your birth control pill.
  • If you use the Sunday Start, use non-hormonal back-up contraception such as condoms and spermicide for the first 7 days that you take Femynor. You do not need back-up contraception if you use the Day 1 Start.

If you start taking Femynor and you are switching from another birth control pill:

  • Start your new Femynor pack on the same day that you would start the next pack of your previous birth control method.
  • Do not continue taking the pills from your previous birth control pack.

If you start taking Femynor and previously used a vaginal ring or transdermal patch:

  • Start using Femynor on the day you would have reapplied the next ring or patch.

If you start taking Femynor and you are switching from a progestin-only method such as an implant or injection:

  • Start taking Femynor on the day of removal of your implant or on the day when you would have had your next injection.

If you start taking Femynor and you are switching from an intrauterine device or system (IUD or IUS):

  • Start taking Femynor on the day of removal of your IUD or IUS.
  • You do not need back-up contraception if your IUD or IUS is removed on the first day (Day 1) of your period. If your IUD or IUS is removed on any other day, use non-hormonal back-up contraception such as condoms and spermicide for the first 7 days that you take Femynor.

Keep a calendar to track your period:

If this is the first time you are taking birth control pills, read, "When should I start taking Femynor ?" above. Follow these instructions for either a Sunday Start or a Day 1 Start.

Sunday Start:

You will use a Sunday Start if your healthcare provider told you to take your first pill on a Sunday.

  • Take pill 1 on the Sunday after your period starts.
  • If your period starts on a Sunday, take pill "1" that day and refer to Day 1 Start instructions below.
  • Take 1 pill every day in the order on the blister pack at the same time each day for 28 days.
  • After taking the last pill on Day 28 from the blister pack, start taking the first pill from a new pack, on the same day of the week as the first pack (Sunday). Take the first pill in the new pack whether or not you are having your period.
  • Use non-hormonal back-up contraception such as condoms and spermicide for the first 7 days of the first cycle that you take Femynor.

Day 1 Start:

You will use a Day 1 Start if your doctor told you to take your first pill (Day 1) on the first day of your period.

  • Take 1 pill every day in the order of the pill blister pack, at the same time each day, for 28 days.
  • After taking the last pill on Day 28 from the blister pack, start taking the first pill from a new pack, on the same day of the week as the first pack. Take the first pill in the new pack whether or not you are having your period.

Femynor comes in a blister pack. Read the instructions below for using your blister pack.

Instructions for using your blister pack:

Each blister pack contains 28 pills:

  • 21 red pills with hormones, for Days 1 to 21.
  • 7 white pills (without hormones), for Days 22 to 28.

Step 1. SET THE DAY

  • Sunday Start: Take the first pill of the first blister pack on the Sunday after your period starts, even if you are still bleeding. If your period begins on Sunday, start the blister pack that same day.
  • Day 1 Start: Take the first pill of the first blister pack during the first 24 hours of your period.

Step 2. Remove the first pill of the blister pack (SUN or Day 1) by pressing the pill through the back of the blister foil.

Step 3. Swallow the pill. You will take 1 pill every day, at the same time each day.

Step 4. Wait 24 hours to take your next pill. Continue to take one pill each day until all pills have been taken.

Step 5. Take your pill at the same time every day. It is important to take the correct pill each day and not miss any pills.

To help you remember, take your pill at the same time as another daily activity, like turning off your alarm clock or brushing your teeth.

What should I do if I miss any Femynor pills?

If you miss 1 red “active” pill in Weeks 1, 2, or 3, follow these steps:

  • Take it as soon as you remember. Take the next pill at your regular time. This means you may take 2 pills in 1 day.
  • Then continue taking 1 pill every day until you finish the pack.
  • You do not need to use a back-up birth control method if you have sex.

If you miss 2 red “active” pills in Week 1 or Week 2 of your pack, follow these steps:

  • Take the 2 missed pills as soon as possible and the next 2 pills the next day.

    • Then continue to take 1 pill every day until you finish the pack.
  • Use a non-hormonal birth control method (such as a condom and spermicide) as a back-up if you have sex during the first 7 days after missing your pills.

If you miss 2 red “active” pills in a row in Week 3, or you miss 3 or more red “active” pills in a row during Weeks 1, 2, or 3 of the pack, follow these steps:

  • If you are a Day 1 Starter:

    • Throw out the rest of the pill pack and start a new pack that same day.
    • You may not have your period this month but this is expected. However, if you miss your period 2 months in a row, call your healthcare provider because you might be pregnant.
    • You could become pregnant if you have sex during the first 7 days after you restart your pills. You MUST use a non-hormonal birth control method (such as a condom and spermicide) as a back-up if you have sex during the first 7 days after you restart your pills.
  • If you are a Sunday Starter:

    • Keep taking 1 pill every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack of pills that same day.
    • Use a non-hormonal birth control method (such as a condom and spermicide) as a back-up if you have sex during the first 7 days after you restart your pills.
