Birth controls pills have been in use since 1960 when the US Food and Drug Administration approved it. Today, there are more than 40 different types to choose from which you can get from your local health rep.
Another name for the pill is called oral contraception. There are two types namely combination and progestin pills. Both are made of hormones and before you can buy it, you need to get prescription from your doctor.
Progestin pills were first introduced in the 1970’s. This pill does not contain estrogen so it does not always prevent ovulation. For this to work, the female must take this at a certain time during the day and this must be taken regularly because one missed pill could greatly reduce its effectiveness.
There are advantages using progestin pills. Since it does not contain estrogen, it can be used by nursing mothers as well as those who are suffering from certain health conditions such as migraine headaches, cardiovascular disease or thromboembolism.
The combination pill contains estrogen and progestin and there three types available.
The first is called Monophasic pills and this contains the same amount of estrogen and progestin because the hormone levels are the same. So, users are less likely to experience mood changes that are a direct result from fluctuating hormone levels in the body.
Some examples of these are Alesse, Brevicon, Desogen, Levlite, Loestrin, Modicon, Nelova and Yasmin. The newest among them is Seasonale that was introduced into the market in 2003. Each pack contains 91 tablets and is designed to prevent menstruation for the entire time period. Tests have shown those who take it will experience only 4 periods in one year.
