That is an introductory explanation of the different types of oral contraceptive pills which could help you to finally select one that is best for your body. 50 years on, we have unearthed that the oral contraceptive pill for women still prevents pregnancy if it’s comprised of much lower doses of estrogen and progestin than in the first days. ‘The Pill’ used to contain 50-100 micrograms of estrogen and today it has only 20-35 micrograms, with researchers trying to reduce this amount further to reduce side effects. Synthetic hormones (estrogen/ethinyl estradiol and progestin) found in contraceptive pills mimic the natural hormones (oestrogen and progesterone) made by the ovaries, adrenal gland and liver.
Estrogen’s main job in a contraceptive pill is to avoid ovulation (release of an egg from the woman’s ovary). Progestin in the pill, whilst it does have some buy xanax online intermittent influence on ovulation (about 50% of the time) is relied on mainly to thicken the mucus round the cervix to avoid sperm from getting right through to an egg.
Contraceptive Pills come in two basic types: single hormone pills (progestin only) and combination hormone pills (estrogen + progestin) Pills are given in two basic packs- 28 day pill packs= 3 weeks of active hormone pills +1 week placebo pills and 21 day pill packs= 3 weeks of active hormone pills without placebo pills.
PROGESTIN only pills (the ‘mini pill’) don’t contain estrogen and just have a little bit of progestin in them. Breastfeeding women in many cases are prescribed these ‘mini pills’ (estrogen may cause a lowering of milk supply) in addition to women who cannot take synthetic estrogen for medical reasons. Negative effects are less than pills containing estrogen and they are not connected with heart disease, however, irregular bleeding /spotting/mood swings may occur. Progestin only pills MUST be used at the same time frame every day and are influenced by vomiting or diarrhoea.This kind of contraceptive pill is not suffering from antibiotics.
COMBINATION PILLS- contain estrogen and progestin and may be further categorized to be Monophasic, Biphasic or Triphasic- so what do these terms mean? Pills are put in these categories in accordance with if the degrees of hormones they contain stay exactly the same throughout the first three weeks of a woman’s menstrual cycle (in 28 day pill packs, the pills for the fourth week in the pack are placebo or ‘reminder pills’ which are inactive and don’t contain any hormones)
MONOPHASIC Pill- is one which has exactly the same quantity of hormones in every ACTIVE pill so you are less likely to have mood swings as your hormone levels don’t vary much throughout the month. Popular monophasic pills include:Alesse, Brevicon, Desogen, Levlen, Levlite, Loestrin, Modicon, Nelova, Nordette, Norinyl,Ortho-Cept, Ortho-Cyclen, Ortho-Novum, Ovcon, Yasmin. In 2003 the FDA approved a brand new packaging of a monophasic contraceptive pill called Seasonale. This pill is taken for 91 days, during which no periods occur -so in twelve months, women taking this pill is only going to have 4 periods (for the first year though, expect exactly the same no. of menstrual days much like a traditional contraceptive pill till the body adjusts)
BIPHASIC PIll- is one which has different amounts of hormones throughout the pack. These pills alter your hormone levels once during your cycle by increasing the dosage of progestin about halfway during your cycle and are thought to better match your body’s natural production of hormones- they contain smaller doses of hormones as a whole than monophasic pills. However, insufficient evidence has been gathered to favour these pills over monophasic ones, where a whole lot more reliable data can be acquired so monophasic pills are preferred. Breakthrough bleeding has been reported as a side effect with your pills. Popular biphasic pills include : Jenest, Mircette, Necon 10/11, Nelova 10/11, Ortho-Novum 10/11. Attempts to decrease unwanted effects led to the three-phase pill in the 1980s.
TRIPHASE pill- is one which has 3 different amounts of hormones in the ACTIVE pills over three weeks, i.e. an alteration in hormone levels within the body occurs every 7 days for the first 3 weeks.. The dose of estrogen is gradually increased and in some pills, the dose of progestin can be increased. Whether three-phase pills cause fewer pregnancies than two-phase pills is unknown. Nor can it be known if the pills give better cycle control or have fewer side effects. Look for the ‘TRI’ on the label such as for example:Ortho Tri-Cyclen, Triphasil, Tri-Levlen, Trivora, Tri-Norinyl, other brands include: Cyclessa, Ortho-Novum 7/7/7.
The Best Pill to Take – All contraceptive pills are effective if taken correctly, with combination pills (containing both estrogen and progestin) being more efficient than the low dose ‘mini pill’ ;.Monophasic pills could be the best in the first place because they are cheaper and people that have lower amounts of estrogen could have fewer unwanted effects (but more breakthrough bleeding)
Always use back up (a condom or diaphragm) for the rest of the month if you miss a pill. Trial and error, unwanted effects and talking to your doctor should help you to look for a contraceptive pill that suits your body. Pregnancies occur mainly when women forget to take a pill or bring them incorrectly, vomit, get diarrhoea or, in the event of the mini pill, don’t take pills at the same time frame each day. It’s very easy to take up a pill packet late if you just forget or if you don’t have the next new packet on hand. The most dangerous time for you to miss a pill is by the end or beginning of a bundle as it lengthens the pill free gap beyond seven days meaning that you might not have absorbed sufficient synthetic hormones to avoid you from ovulating in the next month.
