Many different types of birth control pills are available, and the choices can be overwhelming. Combination, monophasic, biphasic, triphasic, progesterone only and extended cycle birth control pills each have their own purpose. By learning the differences between the types of birth control pills and discussing the options over with a doctor, a woman can feel more confident when deciding which type of birth control pill is best for her.
Progesterone-Only
Progesterone-only birth control pills contain only progesterone, not estrogen, making them ideal for women that are breastfeeding or have other conditions that make taking estrogen undesirable. According to the American Congress of Obstetricians and Gynecologists, these pills may cause less weight gain, nausea, breast tenderness or moodiness than combination birth control pills.
Combination
Combination birth control pills contain two hormones: estrogen and progesterone. Most brands of combination birth control are considered "low dose," which means each pill contains 35 mcg or less of estrogen, according to Babycenter.com. However, different brands will have different amounts of both hormones, so it is always beneficial for a woman to talk to her doctor to decide which option would be best for her.
Monophasic
Monophasic birth control pills contain the same amount of progesterone and estrogen in each active pill. By getting the same dose of hormones on a daily basis, a woman may experience fewer mood changes that can occur with a change in hormone levels, according to Drugs.com.
Multiphasic
Multiphasic birth control pills contain a different amount of hormone depending on the date the pill will be taken. There are two different types of multiphasic pills. Biphasic birth control pills switch the hormone levels once about half way through the menstrual cycle. Triphasic birth control pills, on the other hand, typically switch to a different hormonal level at the end of each week. Varying the level of hormones mimics your own natural menstrual cycle more closely, and may help prevent undesirable side effects, according to Drugs.com.
Extended Cycle
Unlike other birth control pills, which are designed to give you a period once a month, extended cycle pills are meant to be taken for a longer period of time and eliminate the need for monthly menstrual bleeding. Most brands of extended cycle pills contain approximately three months worth of active pills, but other brands have active pills that can be taken up to a full year.
