Contraceptives ( Truths and Myths)
The combined oral contraceptive pill (COCP), that is quite often referred to as the contraceptive pill (CP) or even more commonly known as ‘’the pill’’, is a method of contraception that combines in the same pill an estrogen and a progestogen.
The oral contraceptive pill was approved for use for the first time in the USA in 1960, and is currently the most popular form of birth control. It is used by more than 100 million women worldwide and almost 12 million women in the USA alone.
Combined oral contraceptive pills must be taken at the same time daily. However if one or more tabs are forgotten for over 12 hours their contraceptive protection is drastically reduced. When taking an oral contraceptive that includes 21 pills, 1 pill is taken daily for three weeks followed by a week of not taking pills. Regarding the package of 28 pills, they are taken daily for 21 days followed by a week of placebo pills.
Effectiveness
The contraceptive efficacy of the pill is over 99% if taken according to the instructions.
The effectiveness of contraception may be affected by: 1) missing more than 1active ingredient pill, 2) when taking the 21 pack, a delay for more than 7 days of starting the new package. When using the 28 day package, a delay of more than one day, 3) Intestinal malabsorption due to emesis or diarrhea, 4) Interaction with other drugs that may reduce the serum levels of estrogen or progestogene.
Contraceptive pills can also be used to treat other conditions such as polysystic ovarian syndrome (PCOS), endometriosis, amenorrhea, uterine adenomyosis, heavy bleeding during menses , premenstrual syndrome and acne.
