What is Trisequens?
Trisequens is a hormone replacement therapy (HRT), also called hormone therapy (HT), preparation. It is used to treat women with menopausal symptoms. Trisequens tablets contain estradiol (oestrogen) and norethisterone (progestogen). These hormones restore hormonal balance in the body, and so reduce menopausal symptoms. Trisequens is a prescription-only medicine.
What is Trisequens used for?
Trisequens helps relieve physical and psychological symptoms caused by menopause. Around the age of 45, women’s ovaries start producing less and less oestrogen, and oestrogen levels decline as a result. The declining levels of oestrogen can cause distressing symptoms such as:
- Hot flashes;
- Vaginal discomfort;
- Night sweats;
- Sleeping difficulties;
- Mood swings, anxiety or depression.
The oestrogen (in this case in the form of estradiol) in Trisequens replaces falling oestrogen levels in the body and so helps reduce these uncomfortable symptoms. As oestrogen stimulates the growth of the womb lining, Trisequens also contains a progestogen (in this case in the form of norethisterone) to oppose oestrogen’s effect on the womb lining. Trisequens is a type of HRT that is more suitable for women with an intact womb who are still having (irregular) periods, because it produces a monthly withdrawal bleed.
How to use Trisequens
Each blister pack of Trisequens consists of three types of tablets (28 in total):
- The blue tablets taken on the first 12 days of each Trisequens cycle contain only estradiol.
- The white tablets taken for the next 10 days of each cycle (day 13 to 22) contain both estradiol and norethisterone.
- The red tablets taken from day 23 to 28 contain just estradiol.
Trisequens tablets are taken back to back without a tablet-free interval. The tablets should be taken at the same time each day with some water. They can be taken with or without food. A withdrawal bleed usually occurs in the last week of each cycle. Trisequens tablets come in convenient calendar packs. Consult the package leaflet for instructions on how to take the tablets.
The usual dose for treating adult women is:
- one tablet once daily.
Always follow the prescription exactly - never take more or less than the doctor recommends.
