Ovima 21: Uses, Side Effects and Dosage

ABOUT THIS MEDICATION

What the medication is used for:

• To prevent pregnancy

What it does:

OVIMA is a birth control pill (oral contraceptive) that contains two female sex hormones (levonorgestrel and ethinyl estradiol).

It has been shown to be highly effective in preventing pregnancy when taken as prescribed by your doctor. Pregnancy is always more risky than taking birth control pills except in smokers older than age 35.

Birth control pills work by inhibiting the monthly release of an egg(s) by the ovaries. Some studies have demonstrated changes in the endometrium (lining of the womb) and mucus produced by the cervix (opening of the uterus) with the use of birth

control pills.

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.

A 99 percent effectiveness rate means that if 100 women used birth control pills for one year, one woman in the group would get pregnant.

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 pill Intrauterine device (IUD) Condom with spermicidal foam or gel Mini-pill Condom Diaphragm with spermicidal foam or gel Spermicide Sponge with spermicide Cervical cap with spermicide Periodic abstinence (rhythm), all types No birth control

less than 1 to 2 less than 1 to 6 1 to 6 3 to 6 2 to 12 3 to 18 3 to 21 3 to 28 5 to 18 2 to 20 60 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.

The effective use of birth control methods other than birth control pills and IUDs requires more effort than taking a single pill every day. It is an effort that many couples undertake successfully

When it Should not be Used:

The birth control pill is not suitable for every woman. In a small number of women, serious side effects may occur. Your doctor can advise you if you have any conditions that would pose a risk to you. If you see a different doctor, inform him/her that you are taking birth control pills. Tell the doctor that your birth control pills are OVIMA. The use of the birth control pill should always be supervised by your doctor.

You should not use OVIMA 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;

ABOUT THE MEDICATION

• Known or suspected cancer of the breast, sex organs, or certain estrogen-dependent cancers;
• Unexplained vaginal bleeding (until a diagnosis is reached by your doctor);
• Partial or complete loss of vision or other vision problems caused by vascular disease (blood vessel disease of the eye);
• History of or actual liver disease or history of or actual benign or malignant liver tumor;
• Jaundice (yellowing of the skin and eyes) or liver disease if still present;
• Heart valve or heart rhythm disorders that may be associated with formation of blood clots;
• Diabetes affecting your circulation;
• Migraines (current or history) with neurological symptoms such as aura (visual or sensory disturbance);
• Uncontrolled high blood pressure;
• Hypersensitivity(allergy) to any of the components of OVIMA (levonorgestrel and ethinyl estradiol tablets) (see What the important non-medicinal ingredients are);
• Known or suspected pregnancy. Birth control pills should never be taken if you think you are pregnant. They will not prevent the pregnancy from continuing. There is no conclusive evidence, however, that the pill can damage a developing child when taken inadvertently during early pregnancy;
• Pancreatitis associated with severe hypertriglyceridemia (current or history). Pancreatitis is the inflammation of the pancreas, marked by abdominal pain, whereas severe hypertriglyceridemia is a very high level of triglycerides in the blood, and may show no symptoms.

WARNINGS AND PRECAUTIONS

Serious Warnings and Precautions

Cigarette smoking increases the risk of serious adverse effects on the heart and blood vessels. This risk increases with age and becomes significant in birth control pill users over 35 years of age. Women who use birth control pills should not smoke.

Birth control pills DO NOT PROTECT against sexually transmitted infections (STIs), including HIV/AIDS.

For protection against STIs, it is advisable to use latex or polyurethane condoms IN COMBINATION WITH birth control pills.

There are conditions that your doctor will want to watch closely or that might cause your doctor to recommend a method of contraception other than birth control pills.

BEFORE you use OVIMA talk to your doctor or pharmacist if the following apply to you:

• Breast conditions

  • A strong family history of breast cancer
  • Breast disorders including pain, discharge from the nipples, thickenings, or lumps. In some circumstances, benefit may be derived from taking the pill; in other cases, adverse effects may follow.
• Diabetes
• High blood pressure
• Abnormal levels of fats in the bloodstream (high cholesterol or triglycerides)
• Cigarette Smoking
• Heart or kidney disease
• Epilepsy/seizures
• History of Depression

ABOUT THE MEDICATION

• Fibroid tumours of the uterus
• Gallbladder or pancreatic disease
• History of liver disease or jaundice
• Family history of blood clots, heart attacks or strokes.

If you see a different doctor, inform him or her that you are using OVIMA.

Tell your doctor if you are scheduled for any laboratory tests since certain blood tests may be affected by hormonal contraceptives.

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

OVIMA should be used only under the supervision of a doctor, with regular follow-up to identify side effects associated with its use. Your visits may include a blood pressure check, a breast exam, an abdominal exam and a pelvic exam, including a Pap smear. Visit your doctor three months or sooner after the initial examination. Afterward, visit your doctor at least once a year.

Use OVIMA only on the advice of your doctor and carefully follow all directions given to you. You must use the birth control pill exactly as prescribed. Otherwise, you may become pregnant. If you and your doctor decide that, for you, the benefits of OVIMA outweigh the risks, you should be aware of the following:

THE RISKS OF USING BIRTH CONTROL PILLS

1. 1.

   Circulatory disorders (including blood clot in legs, lungs, heart, eyes or brain)

   Women who use hormonal contraceptives have a higher incidence of blood clots. Blood clots are the most common serious side effects of birth control pills. The risk of developing clots is especially high during the first year a woman ever uses a hormonal contraceptive. Clots can occur in many areas of the body.

   Be alert for the following symptoms and signs of serious adverse effects. Call your doctor immediately if they occur:

   • Sharp pain in the chest, coughing blood, or sudden shortness of breath. These symptoms could indicate a possible blood clot in the lung;
   • Pain and/or swelling in the calf. These symptoms could indicate a possible clot in the leg;
   • Crushing chest pain or heaviness. These symptoms could indicate a possible heart attack;
   • Sudden severe or worsening headache or vomiting dizziness or fainting, disturbances of vision or speech, or weakness or numbness in an arm or leg. These symptoms could indicate a possible stroke;
   • Sudden partial or complete loss of vision. This symptom could indicate a blood clot in the eye.

Any of these conditions can cause death or disability. Clots also occur rarely in the blood vessels of the eye, resulting in blindness or impaired vision or in a blood vessel leading to an arm or leg, resulting in damage to or loss of a limb.

The risk of clotting seems to increase with higher estrogen doses. It is important, therefore, to use as low a dosage of estrogen as possible.

1. 2.

   Breast cancer

   The most significant risk factors for breast cancer are increasing age and a strong history of breast cancer in the family (mother or sister). Other established risk factors include obesity, never having children, and having your first full-term pregnancy at a late age.

   Some women who use birth control pills may be at increased risk of developing breast cancer before menopause, which occurs around age 50. These women may be long-term users of birth control pills (more than eight years) or women who start using Birth control pills at an early age. In a few women, the use of Birth control pills may

ABOUT THE MEDICATION

accelerate the growth of an existing but undiagnosed breast cancer. Early diagnosis, however, can reduce the effect of breast cancer on a woman's life expectancy. The potential risks related to birth control pills seem to be small, however; a yearly breast examination by a doctor is recommended for all women.

ASK YOUR DOCTOR FOR ADVICE AND INSTRUCTIONS ON REGULAR SELF-EXAMINATION OF YOUR BREASTS.

1. 3.

   Cervical cancer

   Some studies have found an increase of cancer of the cervix in women who use hormonal contraceptives, although this finding may be related to factors other than the use of oral contraceptives. However, there is insufficient evidence to rule out the possibility that oral contraceptives may cause such cancers.

   Chronic infection with the Human Papilloma Virus (HPV) is believed to be the most important risk factor for cervical cancer. In women who use COCs for a long time the chance of getting cervical cancer may be slightly higher. This finding may not be caused by the Pill itself but may be related to sexual behavior and other factors.

2. 4. Liver tumors

The short and long-term use of birth control pills have also been linked with the growth of liver tumors or liver injury (e.g., hepatitis, hepatic function abnormal). Such tumors are extremely rare.

Contact your doctor immediately if you experience severe pain or a lump in the abdomen.

1. 5.

   Gallbladder disease

   Users of birth control pills have a greater risk of developing gallbladder disease requiring surgery within the first year of use. The risk may double after four or five years of use.

2. 6.

   Use in pregnancy

   Birth control pills should not be taken by pregnant women. They will not prevent the pregnancy from continuing. There is no evidence, however, that the birth control pill can damage a developing child. You should check with your doctor about risks to your unborn child from any medication taken during pregnancy.

3. 7.

   Use after pregnancy, miscarriage or an abortion

   Your doctor will advise you of the appropriate time to start the use of OVIMA after childbirth, miscarriage, or therapeutic abortion.

   1. 8.

      Pregnancy after stopping OVIMA

      You will have a menstrual period when you stop using OVIMA. You should delay pregnancy until another menstrual period occurs within four to six weeks. In this way the pregnancy can be more accurately dated. Contact your doctor for recommendations on alternate methods of contraception during this time.

   2. 9.

      Use while breast feeding

      If you are breast-feeding, consult your doctor before starting the birth control pill. The hormones in birth control pills are known to appear in breast milk. Adverse effects on the child have been reported, including yellowing of the skin (jaundice) and breast enlargement. You should use another method of contraception. The use of oral contraceptives is generally not recommended until the nursing mother has completely weaned her child.

INTERACTIONS WITH THIS MEDICATION

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 nonhormonal method of contraception during any cycle in which you take drugs that can make oral contraceptives less effective.

Drugs that may interact with OVIMA include:

• 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

ABOUT THE MEDICATION

• 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 doctor 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 doctor or dentist who prescribes another drug (or the dispensing pharmacist) that you use OVIMA. 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 OVIMA. Talk to your doctor for more information about drug interactions.

If your period starts on Sunday, start that same day. If OVIMA tablets administration is initiated after Day 1 of the first menstrual cycle or postpartum, contraceptive reliance should not be placed on OVIMA until after the first seven active tablets have been 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.

   1. 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).

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 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.

WHAT TO DO IF YOU MISS PILLS

Birth control pills may not be as effective if you miss pills. The following chart outlines the actions you should take if you miss one or more of your birth control pills. Match the number of pills missed with the appropriate starting time for your type of pill pack.

ABOUT THE MEDICATION

NOTE: 28-DAY PACK – If you forget any of the seven “reminder” pills (without hormones) in Week 4, just safely dispose of the pills you missed. Then keep taking one pill each day until the pack is empty. You do not need to use a back-up method.

Always be sure you have on hand:

• a non-hormonal back-up method of birth control (such as latex condoms and spermicidal foam or gel) in case you miss pills, and
• an extra, full pack of pills.

IF YOU FORGET MORE THAN ONE PILL TWO MONTHS IN A ROW, TALK TO YOUR DOCTOR OR CLINIC about ways to make pill-taking easier or about using another method of birth control.

SIDE EFFECTS AND WHAT TO DO ABOUT THEM

Some users of birth control pills have unpleasant side effects. Most side effects are temporary and are not hazardous to the health.

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. They are not an indication to stop taking birth control pills. Unless more significant complications occur, a decision to stop using the pill or to change the brand of pill should be made only after three consecutive months of use. Occasionally, users develop high blood pressure that may require stopping the use of birth control pills.

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.

Infrequently, there is a need to change contact lens prescription or an inability to use contact lenses.

A woman’s 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. As mentioned, it is wise to delay starting a pregnancy for one menstrual period after stopping birth control pills.
