Intra-uterine system (Mirena®)
Mirena® is
a hormone-releasing intra-uterine system which releases progestogen into the
womb. It is a highly effective contraceptive but also drastically cuts down the
amount of bleeding and pain with menstrual periods by making the womb lining
thin. It is fitted into the womb like a normal IUD. It is therefore an ideal
method for women who have period problems and can also continue to be used when
a woman becomes menopausal and wishes to take HRT. With a Mirena in place, HRT
can be taken in the form of estrogen only whereas normally HRT for women with
an intact womb consists of estrogen and progestogen. Progestogen being delivered
directly into the womb from the Mirena can reduce progestogenic side effects
as well as reducing bleeding. Women should always be warned that there is often
a lot of erratic bleeding and spotting in the first few months of use before
the bleeding pattern settles down. Around a quarter of women using a Mirena® find
that their periods stop altogether.
Barrier methods
Condoms are recommended at all ages to prevent the spread of sexually
transmitted disease, particularly when individuals start a new relationship.
They are an effective method of contraception for all ages when used properly. As
hormone levels begin to change, many women experience vaginal dryness, which
can cause discomfort during intercourse. Vaginal lubricants can be very helpful
but care should be taken if oil-based vaginal lubricants are used along with
condoms, since some can cause latex condoms to break down and hence reduce the
contraceptive effect of the condoms. Diaphragms may be used, often very reliably
in older women.
