Oral
Contraceptives - "The Pill"
The
Pill is a tablet containing synthetic hormones and taken on a daily
basis. When absorbed into a womans bloodstream it prevents the
release of the egg from the ovary, thickens cervical mucous, which hinders
the passage of sperm, and thins the lining of the uterus which minimizes
the chances of fertilization. The freedom the Pill gives has been of
enormous psychological benefit to women since the 1960's.
The pill is available in most countries throughout the world, if you
live in the US or surrounding Islands it can also be purchased online.
More
information.
The
combined Pill contains synthetic forms of the hormones estrogen
and progestogen which interfere with the woman's regular 28 day menstrual
cycle. When the Pill keeps the hormone level artificially constant,
the signal to ovulate is canceled out. Between them, the two hormones
stop you from getting pregnant. The main way in which they do this is
by stopping your ovaries from releasing an egg (ovulating) each month.
Oral
contraceptives should be taken each day at approximately the same time
for maximum effectiveness.
- if
the pill is forgotten one day it should be taken as soon as remembered
and the normal routine resumed;
- for
two days in a row take two the day remembered and two the next;
-
if the pill is taken more than 12 hours late at any point during
the cycle another form of contraception must be used or intercourse
avoided for the remainder of the cycle;
-
if three or more consecutive pills are missed the packet for that
cycle should be thrown away and a new packet started after the next
menstrual period.
It is important to use another form of contraception during the first
two weeks of the next prescription.
The
Pill's effectiveness can be affected by the following:
- certain
antibiotics
- diarrhoea
- forgetting
pills
- vomiting
Before
the Pill is prescribed a thorough medical examination should be carried
out by your health professional to check blood pressure, breasts and
pelvis. This form of contraception is not recommended for women who
have a history of:
-
angina pectoris
- blood
clots in the legs or lungs (thrombosis)
- diabetes
and heart disease
- high
blood pressure
- obesity
- smoking
- tumors
in the breast or sex organs
- unusual,
undiagnosed vaginal bleeding
- varicose
veins
as
the following serious side effects can occur:
- heart
attacks (coronary thrombosis)
- strokes
- thrombosis
(clotting) in the leg veins, possibly leading to a clot in the lung

Leading Brands Available:
The
mini-pill, the progestogen only Pill (POP) is not a low dose
Pill, but one containing a single hormone, progestogen which thickens
the secretions in the cervix making it difficult for sperm to pass.
The combined Pill is far more popular than the mini-Pill. Progestogen
is an artificially manufactured hormone very like progesterone, one
of the female hormones the body produces. The mini-Pill does not contains
any estrogen which is responsible for many of the combined Pill's side
effects.
The
Mini-Pill should be taken at the same time of day every day, even when
you are menstruating. You may easily get pregnant if you do not take
it every day. Even if you are more than three hours late in taking it
you could fall pregnant. Set yourself a fixed time of day to take the
mini-Pill, maybe suppertime or bedtime. The mini-Pill would probably
not be suitable for you if:
- you
are unreliable at taking tablets regularly
- you
work shift work or in a job such as on an an airline where hours
are irregular and disrupted
The
Mini-Pill is suitable for women:
- who
are at special risk of heart disease or strokes (DO NOT TAKE
the mini-Pill without consulting a specialist)
- who
are breast-feeding
mums
- who
are over 40 who have been medically advised not to take the Pill
- who
are heavy smokers
- who
cannot take estrogen
Doctors
may refuse to prescribe the mini-Pill if you:
- are
too obese as the mini-Pill may not provide a big enough dose
- have
an abnormally high cholesterol or other blood fats
- have
breast cancer
- have
ever had an ectopic pregnancy
- have
unexplained vaginal bleeding
Some
brands of the mini-Pill include:
- Femulen
- Micronor
- Microval
- Neogest
- Norgeston
- Noriday

Implant
(Norplant)
Norplant
is a relatively new contraceptive method which involves six matchstick-size
implants being inserted in the skin of a womans inner arm in a
fan-like pattern under a local anesthetic in a simple, almost pain free
procedure. These sticks release a continuous low dosage of a synthetic
hormone into the bloodstream inhibiting ovulation and thickening the
cervical mucous. It causes changes in the lining of the uterus that
interfere with the ability of fertilized eggs to implant in the uterus.
Norplant is one of the most effective methods of birth control available
to women today and is effective for five years, but may be removed earlier
if desired. "Contraceptive Research, Introduction, and Use:
Lessons from Norplant" by Polly F. Harrison is a book that
can be useful for any woman with, or considering Norplant or other hormonal
implants.More

Implant
(Implanon)
This
is new on the market and can only be administered by doctors and nurses
who have been trained to insert it. Effectiveness rates are difficult
to asses because of its newness. To date, however, no women taking
part in the research trials has become pregnant. A check up 3 months
after the insertion of the implant should be undertaken and the implant
should not be left in place for longer than 3 years.
Implanon's
active ingredient is Etonogestrel Organon, which is a synthetic form
of the naturally occurring female sex hormone, progesterone. In a
woman's normal menstrual cycle, an egg matures and is released from
the ovaries (ovulation), which then produces progesterone, preventing
the release of further eggs and priming the lining of the womb for
a possible pregnancy. If pregnancy occurs, progesterone levels in
the body remain high, maintaining the womb lining. If pregnancy does
not occur, progesterone levels in the body fall, resulting in a menstrual
period.
The
etonogestrel implant is injected under the skin of the arm to slowly
release the hormone into the body, maintaining a high level of the
hormone in the blood. It provides contraception for 3 years but can
removed at any time by your doctor or family planning nurse.
Etonogestrel
works by tricking the body into thinking that ovulation has already
occurred, by maintaining high levels of the synthetic progesterone
which prevents the release of eggs from the ovaries. It also increases
the thickness of this mucus by affecting the natural mucus at the
neck of the womb (cervix) making it more difficult for sperm to cross
from the vagina into the womb.
This
medicine will not protect you or your partner from sexually transmitted
diseases, so you should use a condom to provide this protection. In
women who are heavier than normal, the contraceptive effect of this
implant may not last for 3 years. Also consult your doctor if you
are to be immobilized for a long time due to surgery or illness.
Implanon
should be used with caution in people with a history of:
- blood
clots in the blood vessels (thromboembolism)
- breast
cancer
- decreased
liver function
- diabetes
- high
blood pressure (hypertension)
- a
tendency to suffer from irregular yellowish-brown skin patches
on the face and other areas often due to pregnancy or the use
of oral contraceptives (chloasma) - avoid exposure to the sun
or ultraviolet radiation whilst using this implant
Implanon
should not be used in:
- a
type
of cancer affected by progestogens
- blood
clots in the blood vessel (thrombosis) that may travel through
the vessels (thromboembolism)
- current
or previous severe liver disease
- pregnancy
or suspected pregnancy (may be present in breast milk)
- vaginal
bleeding of unknown cause
- allergy
to one or any of its ingredients (stop using this medicine and
inform your doctor or pharmacist immediately if you feel you have
experienced an allergic reaction)

Injection
Depo-Provera
Depro-Provera
is
a highly effective form of contraception. An injection of a progestogen
hormone which is slowly released into the body is given once every
three months. This prevents ovulation and interferes with eggs leaving
the ovaries, as well as causing a thickening of the cervical mucus
and changes in the lining of the uterus which prevents sperm from
entering the uterus.
Before
commencing Depro-Provera a medical examination is required to check
blood pressure, breasts and pelvis The injection is given in the buttocks
or upper arm. Depro-Provera begins to give protection against pregnancy
within 24 hours of the first injection, which must be given within
five days of the beginning of a period unless the woman has been using
the Pill or an IUD. As the effect slowly wears off over time protection
from pregnancy after the 3 month mark is not assured.
Noristerat
is a similar injection which gives contraceptive protection for eight
weeks.
At
the present time Depo-Provera is far more widely used than
Noristerat.
You
should not have injections if you:
- have
any type of heart disease
- have
breast or womb cancer
- have
liver disease or jaundice
- have
sickle cell anemia
- have
suffered from bad depression
- might
be pregnant
