Cerelle is an oral contraceptive, also referred to as the ‘mini pill’, or the ‘progestogen-only pill’ (POP). It comes in the form of a 1-per-day 75mcg tablet and is taken for 28 days. Unlike combined contraceptives that contain two active ingredients, this pill contains only one active ingredient, artificial progestogen (i.e. desogestrel), which is similar to the natural progestogens produced by the body.
