LIZINNA is a brand name for Norgestimate. The medicine, its uses, side effects and dosage are the same regardless of brand.
Used for: Contraception and the recognised indications for such oestrogen/progestogen combinations. The decision to prescribe Lizinna should take into consideration the individual woman’s current risk factors, particularly those for venous thromboembolism (VTE), and how the risk of VTE with Lizinna compares with other Combined…

For oral administration. Adults How to take Lizinna One tablet is taken daily at the same time (preferably in the evening) without interruption for 21 days, followed by a break of 7 tablet-free days. Each subsequent pack is started after the 7 tablet-free days have elapsed.
Additional contraceptive precautions are not then required. During the tablet-free period, bleeding can be expected, usually beginning 2 to 4 days after the last tablet. Starting treatment It is preferable that tablet intake from the first pack is started up to and including day 5 of menstruation in which case no extra contraceptive precautions are necessary.
Lizinna can be started at any other time, if pregnancy can reasonably be excluded. In this case additional contraceptive precautions must be taken for the first 7 days of tablet taking Switching from another contraceptive Hormonal methods: Lizinna can be started immediately if the patient has been using the current hormonal method consistently and correctly, or if pregnancy can reasonably be excluded.
There is no need to wait for the next menstruation. Additional contraceptive precautions are not required.
Non-hormonal methods:
If Lizinna is started after the first 5 days of menstruation, additional contraceptive precautions are required for the next 7 days. Post-partum administration Following a vaginal delivery, oral contraceptive administration to non-breast- feeding mothers can be started 21 days post-partum provided the patient is fully ambulant and there are no puerperal complications.
No additional contraceptive precautions are required. If post-partum administration begins more than 21 days after delivery, additional contraceptive precautions are required for the first 7 days of pill-taking. If intercourse has taken place post-partum, oral contraceptive use should be delayed until the first day of the first menstrual period.
6. Use after Abortion or Miscarriage After an abortion or miscarriage that occurs prior to 24 weeks gestation, oral contraceptives can be started immediately. An additional method of contraception is not needed. After an induced or spontaneous abortion that occurs at or after 24 weeks gestation, hormonal contraceptives may be started either on Day 21 post- abortion or on the first day of the first spontaneous menstruation, whichever comes first.
Description of selected adverse reactions An increased risk of arterial and venous thrombotic and thromboembolic events, including myocardial infarction, stroke, transient ischemic attacks, venous thrombosis and pulmonary embolism has been observed in women using CHCs.
4. These adverse drug reactions (ADRs) require immediate medical attention and/or cessation of oral contraceptive use. The following ADRs may also require immediate medical attention and/or cessation of CHC use: retinal vein thrombosis, new onset of migraine -type headache, breast cancer, hepatic tumours, adenomas, high blood pressure, angioedema, urticaria and hypersensitivity.
Alternative non-hormonal methods of contraception should be used, while appropriate diagnostic and therapeutic measures are undertaken. 9%). 8%). 9%). The incidence of these ADRs was highest in cycle 1 and decreased over time with the exception dysmenorrhoea.
8%). The 5 clinical trials (2 randomised active-controlled trials and 3 uncontrolled open- label trials), which were used to evaluate the safety of , included 1,891 healthy women of child bearing potential. In 3 trials, subjects were followed for up to 24 cycles and in the other 2 trials for up to 12 cycles.
An additional uncontrolled study (n=8,331) reported ADRs by treatment cycle for up to 24 cycles. As the frequency of ADRs vary according to the cycle of treatment, the highest cycle incidence has been used to assign the ADR to a frequency category.
The table below displays all ADRs that have been reported with the use of Norgestimate / Ethinylestradiol in clinical trials or from post marketing experiences with norgestimate and ethinyl estradiol tablets.

Warnings If any of the conditions/risk factors mentioned below is present, the suitability of Lizinna should be discussed with the woman. In the event of aggravation, or first appearance of any of these conditions or risk factors, the woman should be advised to contact her doctor to determine whether the use of Lizinna should be discontinued.
Exclude likelihood of pregnancy before starting treatment. Undiagnosed vaginal bleeding should be investigated further. Serum folate levels may be depressed by oral contraceptive therapy. This may be of clinical significance if a woman becomes pregnant shortly after discontinuing oral contraceptives.
8). Depression can be serious and is a well-known risk factor for suicidal behaviour and suicide. Women should be advised to contact their physician in case of mood changes and depressive symptoms, including shortly after initiating the treatment.
Medical examination/consultation Prior to the initiation or reinstitution of Lizinna a complete medical history (including family history) should be taken and pregnancy must be ruled out. 4). It is important to draw a woman’s attention to the information on venous and arterial thrombosis, including the risk of Lizinna compared with other CHCs, the symptoms of VTE and ATE, the known risk factors and what to do in the event of a suspected thrombosis.
The woman should also be instructed to carefully read the user leaflet and to adhere to the advice given. The frequency and nature of examinations should be based upon established practice guidelines and should be adapted to the individual woman.
Women should be advised that oral contraceptives DO NOT protect against HIV infections (AIDS) or any other sexually transmitted disease. Conditions requiring supervision − The theoretical or proven risks usually outweigh the advantages of using Combined Oral Contraceptives (COCs) in the conditions listed below.

No additional contraceptive precautions are required. To skip a period To skip a period, a new pack of Lizinna should be started on the day after finishing the current pack (the patient skips the tablet-free days). Tablet-taking should be continued in the usual way.
During the use of the second pack she may experience slight spotting or break- through bleeding but contraceptive protection will not be diminished provided there are no tablet omissions. The next pack of Lizinna is started after the usual 7 tablet-free days, regardless of whether the period has completely finished or not.
Reduced reliability When Lizinna is taken according to the directions for use, the occurrence of pregnancy is highly unlikely. However, the reliability of oral contraceptives may be reduced under the following circumstances: (i) Missed tablets If the patient forgets to take one tablet or if a new strip is started one day late, she should take it as soon as she remembers and take the next one at the normal time.
This may mean that two tablets are taken in one day. No additional contraceptive precautions are required. If more than one tablet is missed or if a new strip is started more than one day late, she should take the last missed tablet as soon as she remembers but leave the other missed tablets in the strip.
g. condom, diaphragm, plus spermicide) for the next 7 days. If the tablets are missed: • In week 1 If unprotected sex has taken place, the use of emergency contraception should be considered. The usual 7-day break can be left before starting the next strip.
• In week 2 The usual 7-day break can be left before starting the next strip. • In week 3 When the strip is finished the next strip should be started the next day without a break. If withdrawal bleeding does not occur at the end of the second strip, a pregnancy test should be performed.
(ii) Vomiting or diarrhoea If a patient vomits within two hours of taking a tablet she should take another tablet from a spare strip. If severe vomiting or diarrhoea continues for more than one day, she should follow the procedure for missed tablets (and continue taking the tablets if she can).

Consequently the decision to prescribe the COC must be made with specialist clinical judgement. 3 and “Circulatory disorders” below) − Adequately controlled hypertension (persistently elevated baseline systolic values 140-159 mmHg or diastolic values 90-94 mmHg) − Obesity (BMI ≥ 35kg/m2) − History of cholestasis (related to COCs), current or medically treated gall bladder disease, porphyria − History of breast cancer, 5 years disease-free.
Circulatory disorders Risk of Venous Thromboembolism (VTE) The use of any CHCs increases the risk of venous thromboembolism (VTE) compared with no use. Products that contain levonorgestrel, norgestimate (including Lizinna) or norethisterone are associated with the lowest risk of VTE.
The decision to use Lizinna should be taken after a discussion with the woman to ensure she understands the risk of VTE with Lizinna, how her current risk factors influence this risk, and that her VTE risk is highest in the first ever year of use.
There is also some evidence that the risk is increased when a CHC is re- started after a break in use of 4 weeks or more. In women who do not use a CHC and are not pregnant, about 2 out of 10,000 will develop a VTE over the period of one year.
However, in any individual woman the risk may be far higher, depending on her underlying risk factors (see below). It is estimated that out of 10,000 women who use a CHC that contains levonorgestrel, about 6 will develop a VTE in a year.
Current evidence suggests that the risk of VTE with use of norgestimate-containing CHCs is similar to the risk with levonorgestrel-containing CHCs. This number of VTEs per year is fewer than the number expected in women during pregnancy or in the postpartum period.
VTE may be fatal in 1-2% of cases. g. hepatic, mesenteric, renal or retinal veins and arteries. Risk factors for VTE The risk for venous thromboembolic complications in CHC users may increase substantially in a woman with additional risk factors, particularly if there are multiple risk factors (see table).
3). If a woman has more than one risk factor, it is possible that the increase in risk is greater than the sum of the individual factors – in this case her total risk of VTE should be considered. 3).
Table:
Risk factors for VTE Risk factor Comment Obesity (body mass index over 30kg/m²) Risk increases substantially as BMI rises. Particularly important to consider if other risk factors also present. Prolonged immobilisation, major surgery, any surgery to the legs or pelvis, neurosurgery, or major trauma Note: temporary immobilisation including air travel >4 hours can also be a risk factor for VTE, particularly in women with other risk factors In these situations it is advisable to discontinue use of the Pill (in the case of elective surgery at least four weeks in advance) and not resume until two weeks after complete remobilisation.
Another method of contraception should be used to avoid unintentional pregnancy. Antithrombotic treatment should be considered if Lizinna has not been discontinued in advance. g. before 50) If a hereditary predisposition is suspected, the woman should be referred to a specialist for advice before deciding about any CHC use.
