Since desogestrel causes ovulation inhibition close to 100%, in contrast to other progestogen-only pills, irregular bleeding is more common than with other progestogen-only pills.

If any of the conditions/risk factors mentioned below is present, the benefits of progesterone use should be weighed against the possible risks for each individual woman and discussed with the woman before she decides to start with Desogestrel 75 micrograms Tablets.

The risk for breast cancer increases in general with increasing age. During the use of combined oral contraceptives (COCs) the risk of having breast cancer diagnosed is slightly increased. This increased risk disappears gradually within 10 years after discontinuation of COC use and is not related to the duration of use, but to the age of the woman when using the COC.
The expected number of cases diagnosed per 10 000 women who use combined OCs (up to 10 years after stopping) relative to never users over the same period have been calculated for the respective age groups and is presented in the table below.
7 44 30-34 years 110 100 35-39 180 160 years 40-44 years 260 230 The risk in users of progestogen-only contraceptives (POCs), such as Desogestrel 75 micrograms Tablets is possibly of similar magnitude as that associated with combined OCs.
However, for POCs the evidence is less conclusive. Compared to the risk of getting breast cancer ever in life, the increased risk associated with COCs is low. The cases of breast cancer diagnosed in COC users tend to be less advanced than in those who have not used COCs.
The increased risk in COC users may be due to an earlier diagnosis, biological effects of the pill or a combination of both. Since a biological effect of progestogens on liver cancer cannot be excluded an individual benefit/risk assessment should be made in woman with liver cancer.
