Tridestra tablets are a hormone replacement therapy to help treat symptoms caused by menopause. The calendar pack helps patients easily keep on track with their prescribed course.
All women go through the natural process of the menopause. The age at which it starts can vary greatly but the average age in the UK is around 51 years. Regular menstrual periods stop, as the process of ovulation no longer occurs.
The production of the natural female hormone known as oestrogen decreases over time. The drop in oestrogen levels during the menopause can cause a number of symptoms. Some of the more common symptoms include: hot flushes, night sweats, irritability, vaginal dryness and headaches. It is also important to note that once menopause has started women can become susceptible to the development of osteoporosis, a condition where bone mass decreases.
Menopausal symptoms do not cause significant problems for all women. The degree of symptoms can vary greatly and mild cases don’t usually require treatment. Severe cases can lead to symptoms that cause significant impact on daily lives and thus require medical intervention, such as HRT.
There are several types of hormone replacement therapy. The HRT that your doctor suggests for you can depend on your specific situation and past medical history. Oestrogen-only products are more typically supplied to women who may have had part of their womb surgically removed during a hysterectomy. This type of HRT supplements the drop in oestrogen levels to help lessen the symptoms. Combined HRT contains both oestrogen and progesterone. This type of hormone replacement tends to be prescribed to women who have not had their uterus removed.
Whilst Tridestra is a combined HRT, it is also known as a sequential treatment. Unlike other monthly sequential treatments, Tridestra is a three-month sequence. The white tablets, taken at the beginning of the cycle for the first 70 days, only contain the active ingredient estradiol; the blue tablets taken between days 71 to 84 contain estradiol and medroxyprogesterone; and the yellow tablets taken between days 85 to 91 are a placebo and contain no active ingredient. This sequence can cause a menstrual-like bleed every three months and may be suited to women who are already experiencing infrequent periods.
