MERCILON is a brand name for Desogestrel. The medicine, its uses, side effects and dosage are the same regardless of brand.
Used for: Oral contraception. The decision to prescribe Mercilon should take into consideration the individual woman’s current risk factors, particularly those for venous thromboembolism (VTE), and how the risk of VTE with Mercilon compares with other CHCs (see sections 4.3 and 4.4).

1 How to take Mercilon Tablets must be taken in the order directed on the package every day at about the same time with some liquid as needed. One tablet is to be taken daily for 21 consecutive days. Each subsequent pack is started after a 7-day tablet-free interval, during which time a withdrawal bleed usually occurs.
This usually starts on day 2-3 after the last tablet and may not have finished before the next pack is started. 2 How to start Mercilon No preceding hormonal contraceptive use [in the past month]: It is preferable that tablet intake from the first pack is started on the first day of menstruation in which case no extra contraceptive precautions are necessary.
If menstruation has already begun, (that is 2, 3, or 4 days previously), tablet taking should commence on day 5 of the menstrual period. In this case additional contraceptive precautions must be taken for the first 7 days of tablet taking.
If menstruation began more than 5 days previously then the patient should be advised to wait until her next menstrual period before starting to take Mercilon.
Changing from a 21 day pill or another 22 day pill to Mercilon:
All tablets in the old pack should be finished. e. no gap is left between taking tablets nor does the patient need to wait for her period to begin. Tablets should be taken as instructed in ‘How to take Mercilon’. Additional contraceptive precautions are not required.
The patient will not have a period until the end of the first Mercilon pack, but this is not harmful, nor does it matter if she experiences some bleeding on tablet-taking days. e. after taking 21 or 22 tablets). e. no gap is left between taking tablets nor does the patient need to wait for her period to begin.
One tablet is taken daily at the same time, without interruption for 21 days, followed by a 7 day tablet-free period. Each subsequent pack is started after the 7 day tablet-free period has elapsed. Additional contraceptive precautions are not required.
Remaining tablets from the Every Day (ED) pack should be discarded. The patient will not have a period until the end of the first Mercilon pack, but this is not harmful, nor does it matter if she experiences some bleeding on tablet-taking days.
Description of selected adverse reactions As with all COCs, changes in vaginal bleeding patterns may occur, especially during the first months of use. These may include changes in bleeding frequency (absent, less, more frequent or continuous), intensity (reduced or increased) or duration.

4 Special warnings and special precautions for use: The Pill and Cancer). • Endometrial hyperplasia. • Undiagnosed vaginal bleeding. • Known or suspected pregnancy. 1. 5). 1 Warnings If any of the conditions or risk factors mentioned below is present, the suitability of Mercilon 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 Mercilon should be discontinued. 1. Circulatory Disorders Risk of venous thromboembolism (VTE) • The use of any combined hormonal contraceptive (CHC) increases the risk of venous thromboembolism (VTE) compared with no use.
Products that contain levonorgestrel, norgestimate or norethisterone are associated with the lowest risk of VTE. Other products such as Mercilon may have up to twice this level of risk. The decision to use any product other than one with the lowest VTE risk should be taken only after a discussion with the woman to ensure she understands the risk of VTE with Mercilon, 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 estimated1 that out of 10,000 women who use a CHC containing desogestrel between 9 and 12 women will develop a VTE in one year; this compares with about 62 in women who use a levonorgestrel-containing CHC.
In both cases, the number of VTEs per year is fewer than the number expected during pregnancy or in the postpartum period. • VTE may be fatal in 1-2% of cases. 1 These incidences were estimated from the totality of the epidemiological study data, using relative risks for the different products compared with levonorgestrel-containing CHCs.
Combined hormonal contraceptives (CHCs) should not be used in the presence of any of the conditions listed below. Should any of the conditions appear for the first time during CHC use, the product should be stopped immediately. g. deep venous thrombosis [DVT] or pulmonary embolism [PE]).
o Known hereditary or acquired predisposition for venous thromboembolism, such as APC-resistance, (including Factor V Leiden), antithrombin-III- deficiency, protein C deficiency, protein S deficiency. 4). 4). g. g. g. transient ischaemic attack, TIA).

Changing from a Progestogen -only Pill (POP or Mini Pill) to Mercilon:
The first Mercilon tablet should be taken on the first day of the period, even if the patient has already taken a mini pill on that day. One tablet is taken daily at the same time, without interruption for 21 days, followed by a 7 day tablet-free period.
Each subsequent pack is started after the 7 day tablet-free period has elapsed. Additional contraceptive precautions are not then required. All the remaining Progestogen-only pills in the mini pill pack should be discarded. If the patient is taking a (mini) pill, then she may not always have a period, especially when she is breast feeding.
The first Mercilon tablet should be taken on the day after stopping the mini pill. All remaining pills in the mini pill packet must be discarded. Additional contraceptive precautions must be taken for the first seven days. Changing from a progestogen-only injection, implant or from a progestogen- releasing intrauterine system [IUS]: The woman may switch any day from an implant (or the IUS on the day of its removal, from an injectable when the next injection would be due).
Additional contraceptive precautions must be taken for the first seven days.
Post-Partum Administration:
Following childbirth hormonal contraceptive administration to non-breast feeding mothers should be started 21 days post-partum in which case no additional contraceptive precautions are required. If intercourse has taken place post-partum, hormonal contraceptive use should be delayed until the first day of the menstrual period.
If post-partum administration of Mercilon begins more than 21 days after delivery then additional contraceptive precautions are required for the first 7 days. B. Mothers who are breast feeding should be advised not to use the combined pill since this may reduce the amount of breast-milk, but may be advised instead to use a progestogen-only pill (POP).
After miscarriage or abortion administration should start immediately in which case no additional contraceptive precautions are required.
Additional contraceptive precautions:
When additional contraceptive precautions are required the patient should be advised either not to have sex, or to use a cap plus spermicide, or for her partner to use a condom. g. changes in temperature and cervical mucus.
How to skip a period:
To skip a period, a new pack of Mercilon 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 breakthrough bleeding but contraceptive protection will not be diminished provided there are no tablet omissions.
The next pack of Mercilon is started after the usual 7 tablet-free days, regardless of whether the period has completely finished or not. 3 Management of missed tablets Advice in case of missed pills The reliability of Mercilon may be reduced if tablets are forgotten: If the forgotten tablet is taken within 12 hours, no further precautions are necessary, further tablets should be taken at the usual time.
If one or more tablets are forgotten for more than 12 hours, contraceptive protection will be reduced. The patient should take the last forgotten tablet, even if this means taking two tablets in one day, and then […]
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 30 kg/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 patch/pill/ring (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 Mercilon 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.
Other medical conditions associated with VTE Cancer, systemic lupus erythematosus, haemolytic uraemic syndrome, chronic inflammatory bowel disease (Crohn’s disease or ulcerative colitis) and sickle cell disease Increasing age Particularly above 35 years There is no consensus about the possible role of varicose veins and superficial thrombophlebitis in the onset or progression of venous thrombosis.
6). Symptoms of VTE (deep vein thrombosis and pulmonary embolism) In the event of symptoms women should be advised to seek urgent medical attention and to inform the healthcare professional that she is taking a CHC. Symptoms of deep vein thrombosis (DVT) can include: – unilateral swelling of the leg and/or foot or along a vein in the leg; – pain or tenderness in the leg which may be felt only when standing or walking; – increased warmth in the affected leg; red or discoloured skin on the leg.
Symptoms of pulmonary embolism (PE) can include: – sudden onset of unexplained shortness of breath or rapid breathing; – sudden coughing which may be associated with haemoptysis; – sharp chest pain; – […]
