For oral administration.
Adults:
When used perfectly, without missing any pills, the chance of becoming pregnant is less than 1% (i.e. <1 pregnancy per 100 women in their first year of use). Typical failure rates are actually 5% in the first year. The chance of becoming pregnant increases with each missed pill during a menstrual cycle.
Before starting Cilest, a thorough general medical and gynaecological examination (including the breasts and a cytological smear of the cervix) if appropriate should be carried out and the family medical history carefully noted. Disturbances of menstruation, such as oligomenorrhea and amenorrhea should be investigated prior to prescription. Disturbances of the clotting mechanisms should be ruled out if any members of the family have suffered from thrombo-embolic diseases (eg deep vein thrombosis, stroke, myocardial infarction) at a young age.
Pregnancy must be excluded ideally by a pregnancy test.
The woman should be instructed to carefully read the user leaflet and to adhere to the advice given.
As a precaution, thorough medical examinations should be conducted at approximately six month intervals during use of the tablets.
Children:
Safety and efficacy of Cilest Tablets have only been established in women of reproductive age.
Elderly:
Not indicated in post menopausal women.
- First cycle
Tablet-taking from the first pack of Cilest is started on the 1st day of the menstrual cycle, ie the first day of menstrual bleeding. If menstruation has already begun, Cilest may be commenced up to day 5 of the menstrual period, provided additional contraceptive precautions are taken for the first 7 days of tablet taking.
One tablet is to be taken at around the same time of day on each of 21 consecutive days followed by a tablet-free interval of 7 days, during which a withdrawal bleeding occurs.
- Subsequent cycles
