Serious Warnings and Precautions

  • Cigarette smoking increases the risk of serious adverse effects on the heart and blood vessels. This risk increases with age particularly in women older than 35 years of age, who use hormonal birth control. The risk also increases with the number of cigarettes smoked. For this reason, women who smoke and are over 35 years of age should not use ALYSENA.
  • Birth control pills DO NOT PROTECT against sexually transmitted infections (STIs), including HIV/AIDS.
  • For protection against STIs, you must use latex or polyurethane condoms AND take your birth control pills.

What is ALYSENA used for?

  • To prevent pregnancy.
  • To treat moderate acne in women 14 years of age and older who are able to use birth control pills, desire birth control and have achieved menarche. Your first menstrual period is called menarche.

How does ALYSENA work?

ALYSENA is a birth control pill (oral contraceptive). It is considered to be a combination oral contraceptive. This is because it contains two female sex hormones: levonorgestrel and ethinyl estradiol. Combination birth control pills work by:

  • Stopping the monthly release of an egg by the ovaries
  • Changing the endometrium (lining of the womb) and mucus produced by the cervix (opening of the uterus).

Effectiveness of Birth Control Pills

Combination birth control pills are more than 99 percent effective in preventing pregnancy when:

  • the pill is TAKEN AS DIRECTED, and
  • the amount of estrogen is 20 micrograms or more.

The chance of becoming pregnant increases with incorrect use.

Other Ways to Prevent Pregnancy

Other methods of birth control are available to you. They are usually less effective than birth control pills. When used properly, however, other methods of birth control are effective enough for many women.

The following table gives reported pregnancy rates for various forms of birth control, including no birth control. The reported rates represent the number of women out of 100 who would become pregnant in one year.

Reported Pregnancies per 100 Women per Year:

Combination pillless than 1 to 2
Intrauterine device (IUD)less than 1 to 6
Condom with spermicidal foam or gel1 to 6
Mini-pill3 to 6
Condom2 to 12
Diaphragm with spermicidal foam or gel3 to 18
Spermicide3 to 21
Sponge with spermicide3 to 28
Cervical cap with spermicide5 to 18
Periodic abstinence (rhythm), all types2 to 20
No birth control60 to 85

Pregnancy rates vary widely because people differ in how carefully and regularly they use each method. This does not apply to IUDs since they are implanted in the uterus. Regular users may achieve pregnancy rates in the lower ranges. Others may expect pregnancy rates more in the middle ranges.

What are the ingredients in ALYSENA?

Medicinal ingredients: Levonorgestrel and Ethinyl Estradiol

Non-medicinal ingredients: Corn starch, crospovidone, FD&C Red N°40 Lake, lactose monohydrate, magnesium stearate, and povidone K30.

ALYSENA comes in the following dosage forms:

ALYSENA are available in a 21-day regimen (ALYSENA 21) and a 28-day regimen (ALYSENA 28)

ALYSENA 21: Each package contains 21 pink tablets, engraved “100” on one side, “20” on the other side. Each pink tablet contains 100 mcg levonorgestrel and 20 mcg ethinyl estradiol.

ALYSENA 28: Each blister pack contains 21 pink tablets engraved “100” on one side, “20” on the other side and 7 white tablets. Each pink tablet contains 100 mcg levonorgestrel and 20 mcg ethinyl estradiol. The white tablets are “reminder” tablets (they do not contain hormones).

Do not use ALYSENA if you have or have had any of the following conditions:

  • History of or actual heart attack, chest pain (angina pectoris) or stroke;
  • Blood clots in the legs (thrombophlebitis), lungs (pulmonary embolism), eyes or elsewhere;
  • Hereditary or acquired blood clotting disorders;
  • Known or suspected cancer of the breast, sex organs, or certain estrogen-dependent cancers;
  • Unexplained vaginal bleeding (until a diagnosis is reached by your healthcare professional);

If you see a different healthcare professional, inform him or her that you are using ALYSENA.

Tell your healthcare professional if you are scheduled for any laboratory tests. This is because certain blood tests may be affected by hormonal oral contraceptives.

Also tell your healthcare professional if you are scheduled for MAJOR surgery, recent delivery, or second-trimester abortion. You should tell your healthcare professional about stopping the use of ALYSENA four weeks before major surgery and not using ALYSENA for a time period after surgery or during prolonged bed rest.

ALYSENA should be used only under the supervision of your healthcare professional. Your healthcare professional will schedule regular follow-up visits to identify side effects caused by ALYSENA. Your visits may include a blood pressure check, a breast exam, an abdominal exam and a pelvic exam, including a Pap smear. Visit your healthcare professional three months or sooner after the initial examination. Afterward, visit your healthcare professional at least once a year.

Use ALYSENA only on the advice of your healthcare professional and carefully follow all directions given to you. You must use the birth control pill exactly as prescribed. Otherwise, you may become pregnant.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

Certain drugs may interact with birth-control pills to make them less effective in preventing pregnancy or cause an increase in breakthrough bleeding. You may also need to use a non-hormonal method of contraception during any cycle in which you take drugs that can make oral contraceptives less effective. Your healthcare professional will tell you if you need to use a non-hormonal method of birth control.

The following may interact with ALYSENA:

  • drugs used for epilepsy such as barbiturates (e.g. phenobarbital) and phenytoin, primidone, topiramate, carbamazepine.
  • certain drugs used in the treatment of tuberculosis (eg. rifampicin, rifabutin).
  • drugs used for HIV or AIDS such as ritonavir.
  • herbal products containing St. John’s Wort (Hypericum perforatum).
  • antibiotics (e.g. penicillins, tetracyclines) for infectious diseases.
  • cyclosporine.
  • antifungals (griseofulvin).
  • cholesterol-lowering drugs (eg. clofibrate).
  • antihypertensive drugs (for high blood pressure).
  • antidiabetic drugs and insulin (for diabetes).
  • prednisone.
  • sedatives and hypnotics (eg, benzodiazepines, barbiturates, chloral hydrate, glutethimide, meprobamate).
  • antidepressants (e.g. clomipramine).
  • other drugs such as phenylbutazone, analgesics, modafinil, troleandomycin, Vitamin E and Vitamin B12.
  • anti-viral hepatitis C virus (HCV) medicinal products such as ombitasvir, paritaprevir, ritonavir and dasabuvir, with or without ribavirin.

Please inform your healthcare professional and pharmacist if you are taking or have recently taken any other drugs or herbal products, even those without a prescription. Also tell any other healthcare professional or dentist who prescribes another drug (or the dispensing pharmacist) that you use ALYSENA. They can tell you if you need to use an additional method of contraception and if so, for how long.

This is not a complete list of possible drug interactions with ALYSENA. Talk to your healthcare professional for more information about drug interactions.

How to take ALYSENA?

Usual dose:

  1. 1.

    READ THESE DIRECTIONS

    • Before you start taking your pills, and
    • Any time you are not sure what to do.
  2. 2.

    LOOK AT YOUR PILL PACK to see if it has 21 or 28 pills:

    • 21-Pill Pack: 21 active pills (with hormones) taken daily for three weeks, and then no pills taken for one week;

Or

  • 28-Pill Pack: 21 active pills (with hormones) taken daily for three weeks, and then seven "reminder" pills (no hormones) taken daily for one week.
  1. 3. You may wish to use a second method of birth control (e.g. latex condoms and spermicidal foam or gel) for the first seven days of the first cycle of pill use. This will provide a back-up in case you forgot to take your pills while you are getting used to taking them everyday.
  2. 4. When receiving any medical treatment, be sure to tell your healthcare professional that you are using birth control pills.
  3. 5. Many women have spotting or light bleeding or may feel sick to their stomach during the first three months on the pill. If you do feel sick, do not stop taking ALYSENA. The problem will usually go away. If it does not go away, check with your healthcare professional or clinic.
  4. 6. Missing pills also can cause some spotting or light bleeding, even if you make up the missed pills. You also could feel a little sick to your stomach on the days you take two pills to make up for missed pills.
  5. 7.

    If you miss pills at any time, you could get pregnant. The greatest risks for pregnancy are:

    1. - when you start a pack late or
    2. - when you miss pills at the beginning or at the very end of the pack.
  6. 8.

    Always be sure you have ready:

    1. - Another kind of birth control (such as latex condoms and spermicidal foam or gel) to use as a back-up in case you miss pills, and
    2. - An extra pack of pills.
  7. 9. If you experience vomiting or diarrhea, or if you take certain medicines, such as antibiotics, your pills may not work as well. Use a back-up method, such as latex condoms and spermicidal foam or gel, until you can check with your healthcare professional or clinic.
  8. 10. If you forgot more than one pill two months in a row, talk to your healthcare professional or clinic about how to make pill-taking easier or about using another method of birth control.
  9. 11. If your questions are not answered here, call your healthcare professional or clinic.

When to start the first pack of pills

BE SURE TO READ THESE INSTRUCTIONS:

  • before you start taking your pills, and
  • any time you are not sure what to do.

Decide with your healthcare professional or clinic what is the best day for you to start taking your first pack of pills. Your pills may be either a 21-day or a 28-day type.

DIRECTIONS FOR USE OF THIS STICKER:

Peel the sticker off for the day of the week you plan to start your pills. Place the sticker over the space provided for the days of the week and make sure it lines up with the pills. This sticker will help to remind you to take your pill every day.

  1. A. 21-DAY COMBINATION

With this type of birth control pill, you are on pills for 21 days and off pills for seven days. You must not be off the pills for more than seven days in a row.

  1. 1. The first day of your menstrual period (bleeding) is day 1 of your cycle. Your healthcare professional may advise you to start taking the pills on Day 1, on Day 5, or on the first Sunday after your period begins. If your period starts on Sunday, start that same day. If ALYSENA tablets are started after day 1 of your first cycle or postpartum (the period of time after childbirth) you should not rely on ALYSENA to prevent pregnancy until the first 7 active tablets are taken for seven consecutive days. Nonhormonal methods of contraception (such as latex condoms and spermicidal foam or gel) should be used for the first 7 days of tablet taking.
  2. 2. Take one pill at approximately the same time every day for 21 days, then take no pills for seven days. Start a new pack on the eighth day. You will probably have a period during the seven days off the pill. (This bleeding may be lighter and shorter than your usual period).

Two ways to remember in what order to take the pills

  1. 1. Follow the days of the week (as shown above the pills).
  2. 2. Always finish the pink tablets before going on to the week when you are off pills.

B. 28-DAY COMBINATION

With this type of birth control pill, you take 21 pills that contain hormones and seven pills that contain no hormones.

  1. 1.

    The first day of your menstrual period (bleeding) is day 1 of your cycle. Your healthcare professional may advise you to start taking the pills on Day 1, on Day 5, or on the first Sunday after your period begins. If your period starts on Sunday, start that same day.

    If you start taking ALYSENA tablets are after day 1 of your first cycle or postpartum (the period of time after childbirth) you should not rely on ALYSENA to prevent pregnancy until the first 7 active tablets are taken for seven consecutive days. Non-hormonal methods of contraception (such as latex condoms and spermicidal foam or gel) should be used for the first 7 days of tablet taking.

  2. 2. Take one pill at approximately the same time every day for 28 days. Begin a new pack the next day, NOT MISSING ANY DAYS. Your period should occur during the last seven days of using that pill pack.

Two ways to remember in what order to take the pills

  2. 2. Try to associate taking your pill with some regular activity such as eating a meal or going to bed.
  3. 3. Do not skip pills even if you have bleeding between monthly periods or feel sick to your stomach (nausea).
  4. 4. Do not skip pills even if you do not have sex very often.
  5. 5.

    When you finish a pack

    1. • 21 pills

Wait seven days to start the next pack. You will have your period during that week.

  • 28 pills

Start the next pack ON THE NEXT DAY. Take one pill every day. Do not wait any days between packs.

Overdose:

Overdosage may cause nausea, vomiting, breast tenderness, dizziness, abdominal pain, and fatigue/drowsiness. Withdrawal bleeding may occur in females.

If you think you, or a person you are caring for, have taken too much ALYSENA, contact a healthcare professional, hospital emergency department, or regional poison control centre immediately, even if there are no symptoms.

What are possible side effects from using ALYSENA?

These are not all the possible side effects you may have when taking ALYSENA. If you experience any side effects not listed here, tell your healthcare professional.

  • There may be tenderness of the breast, nausea, and vomiting.

    Some users will experience weight gain or loss. Many of these side effects occurred with high-dose combination birth control pills. These side effects are less common with the low-dose pills prescribed today.

  • Unexpected vaginal bleeding or spotting and changes in the usual menstrual period may also occur. These side effects usually disappear after the first few cycles. This does not mean that you should stop taking your birth control pills. Unless you have more serious side effects, a decision to stop using the pill or to change the brand of pill should be made only

    • This decision should be made with your healthcare professional. You may develop high blood pressure that may require stopping the use of birth control pills. If you develop high blood pressure, talk to your healthcare professional.

Other side effects may include:

  • growth of pre-existing fibroid tumours of the uterus.
  • an increase or decrease in hair growth, sex drive and appetite.
  • skin pigmentation.
  • headaches.
  • abnormal liver test, nausea, vomiting, severe pain or lump in the abdomen.
  • rash and/or
  • vaginal infections.

Sometimes, there is a need to change contact lens prescription or an inability to use contact lenses. Your menstrual period may be delayed after stopping birth control pills. There is no evidence that the use of the pill leads to a decrease in fertility. It is wise to delay starting a pregnancy for one menstrual period after stopping birth control pills.
