What is Tridestra?
Tridestra is a hormone replacement therapy (HRT) preparation. It contains two active ingredients: estradiol (an oestrogen hormone) and medroxyprogesterone (a progestogen hormone). Tridestra tablets are used to treat menopausal symptoms in women. Tridestra is a prescription-only medicine.
What is Tridestra used for?
Women's ovaries gradually produce less and less oestrogen in the period up to menopause, and oestrogen levels decline as a result. The declining levels of oestrogen can cause distressing symptoms. The most common menopausal symptoms include:
- Hot flashes;
- Vaginal discomfort (dryness, pain, irritation);
- Difficulty falling asleep or staying asleep;
- Osteoporosis (decrease in bone mass and density);
- Night sweats;
- Mood swings.
HRT restores hormonal balance. This helps relieve menopausal symptoms. Tridestra is intended for women with an intact womb because it contains a progestogen hormone which protects the lining of the womb from side effects. Tridestra produces a withdrawal bleed every three months.
How to use Tridestra
Tridestra is based on a three-monthly cycle. Each package contains three numbered blisters.
- Blister no. 1 contains white tablets. These tablets are taken for the first 70 days and contain just estradiol.
- Blister no. 2 contains blue tablets, which are taken for days 71 to 84. These tablets contain estradiol and medroxyprogesterone.
- Blister no. 3 contains yellow tablets. These tablets are taken for days 85 to 91 and contain no active ingredient at all (placebo).
The three-monthly cycle results in a withdrawal bleed every three months (between day 85 and day 91). You start the next pack (blister 1) right after you finish the third blister, even if you are still bleeding.
Unless otherwise advised by a doctor, the usual dose in adult women is:
- one tablet, once daily.
Read the package leaflet before use.
HRT may cause side effects. The following are some of the side effects that are known to be associated with Tridestra:
- Breast tenderness;
- Gastrointestinal symptoms such as nausea and stomach ache;
- Breakthrough bleeding (spotting).
Consult a doctor if the side effects are persistent. See the package leaflet for a full list of side effects, including rare yet serious side effects such as cancer and thrombosis.
