What is a morning-after pill or emergency contraception?
The terms ‘emergency contraception' or ‘morning-after pill' suggest that medications belonging to these categories need to be taken on an urgent basis. These medications are capable of relieving a woman from the risk of unwanted or unplanned conception – in case she forgets to take her regular contraceptive pills or the medications don't work. An emergency contraceptive or morning-after pill is another form of hormonal contraceptive but a user needs to take it only when the regular contraceptive used by her and her partner fails. The high dosage of artificial hormones that these pills contain would provide her with the desired protection in a single pill. Currently, in the UK the two most popular morning-after pills are ellaOne and Levonelle.
The basic composition of a morning-after pill
The common feature of all morning-after pills is that they contain high dosages of synthetic progesterone receptor modulator. In case of ellaOne it is ulipristal acetate and in Levonelle, levonorgestrel is used for the same purpose. These chemicals are capable of changing the normal functioning of the natural progestogen hormone and bring necessary changes in your menstrual cycle. However, the best benefits of the pills can be received only when you take them as soon as possible after an incident of contraceptive failure or unprotected sexual intercourse.
