2. What Are The Different Types Of Birth Control Pills?
More information about each type of birth control pills is listed below, along with facts about their effectiveness, how they work against pregnancy and the possible side effects.
3. Combination Birth Control Pills
Like the birth control patch and vaginal ring, combination pills contain two types of the synthetic or man-made hormones progestin and estrogen in different ratios.
Pregnancy is prevented by combination pills through three ways:
A. Preventing ovulation which means your ovaries do not release any eggs.
B. Increasing the thickness of cervical mucus to slow down or make it harder for sperm cells to swim towards the egg cell.
C. Making the lining of the uterus thinner to prevent or make it harder for the egg to adhere to it.
Other benefits associated with combination pills are shorter and lighter periods (which also reduces chances of anemia), less abdominal cramps, less acne, and reduced risk of endometrial and ovarian cancer.
Combination pills are the most popular and come in different hormone ratios that can change throughout the month or depending on the type. Combination pill brands include Enpresse, Azurette, Estrostep Fe, Beyaz, Levora, Loestrin, Kariva, Ocella, Natazia, Ortho-Novum, Low Ogestrel, Seasonale, Ortho-Tri-Cyclen, Yasmin, Velicent, Nordette, Mircette, Apri, Alesse, Aviane, Jolessa, Lybrel, Lessina, and Seasonique.
Pills are either active (contain hormones) or inactive (do not contain any hormones).
A. The two categories based on hormone dosage are monophasic or multiphasic.
i. Monophasic Pills
Monophasic pills contain only one phase or amount of progestin and estrogen every day all throughout the month, hence the name. Used in monthly cycles, women taking this type of pill takes inactive pills at the last week of their cycle to get their period.
ii. Multiphasic Pills
Multiphasic pills vary regarding the amounts of hormone and active ingredients. Different doses or levels of hormones apply depending on where you are in your menstrual cycle. These are also used in one-month cycles and again require inactive pills during the last week of the cycle to get your period. Multiphasic pills may either be biphasic or triphasic.
iii. Biphasic Birth Control Pills
Provide the same amount of estrogen for the first 21 days of the cycle but gives lower amounts of progestin during the first half and higher amounts of progestin in the second half of the cycle. The lower progestin/estrogen ratio during the first half causes the normal thickening of the uterine lining or endometrium. On the second half of the cycle, the higher progestin/estrogen ratio allows this lining to shed normally.
iv. Triphasic Birth Control Pills
Involve three doses or ratios of estrogen and progestin throughout the menstrual cycle.
As of now, there is no scientific evidence to prove whether monophasic pills are more effective than multiphasic pills or vice versa.
B. Other types of combination contraceptive pills are extended-cycle and low-dose pills.
v. Extended-Cycle Pills
Extended-cycle or continuous-dose pills are often used in 13-week cycles wherein 84 active pills are taken for the first 12 weeks then inactive pills are taken in the last week for you to have your period. As a result, you get fewer periods (about three to four) in a year.
vi. Low-Dose Pills
Less than 50 micrograms of estrogen, usually only 35 micrograms or even less are contained in each active low-dose pill. This is a great option for women who are just starting birth control to allow their bodies to adjust. However, while many women achieve high success rates of birth control with these pills, more breakthrough or mid-cycle bleeding is experienced.
vii. Mini Pills
Unlike combination pills, a mini-pill or progestin-only pill does not contain any estrogen on any day of the cycle. This makes this type a better choice for women who are sensitive to estrogen or have certain medical conditions. Many doctors also recommend this type since most birth control pills side effects are due to estrogen. It is also safe for women who are breastfeeding, smokers, are older than 35, have a history of blood clots, or at risk of strokes and heart disease. These may be considered as the best birth control pills with least side effects by some women.
Mini-pills contain the same dosage of progestin which is also lower than the progestin dosage of combination pills. There are no inactive mini pills, so periods are either present or absent. Pregnancy is prevented by thinning the uterine lining and thickening cervical mucus. Some mini pills also prevent ovulation. While combination pills are argued to be significantly more effective than mini-pills, but health or other reasons may leave some women with not much choice and scientific studies have shown that both have the same failure rate, about 1 in 10.
You may know mini pills by its many names including Errin, Jolivette, Camila, Heather, Jencycle, Ortho Micronor, or Nor-QD.
viii. Emergency Contraceptive Pill
The emergency contraceptives pill or also known as the morning-after pill may also be considered as a birth control pill but is more like an alternative. This is taken in the morning or about 120 hours or 5 days after unprotected sex to prevent pregnancy.
