Tridestra is a hormone replacement therapy (HRT). It contains two active ingredients: estradiol (an estrogen hormone) and medroxyprogesterone (a progestin hormone). For women who have not had a hysterectomy, increased estrogen levels can stimulate the growth of the uterine lining, which can cause uterine cancer. The inclusion of progesterone is done to counteract the effects of estrogen on the uterine lining, which reduces the risk of cancer. Tridestra is aimed at women who keep their uterus in good condition, as it contains a progestogen hormone that protects the endometrium from side effects. Tridestra causes withdrawal bleeding every three months.

What is Tridestra?

Tridestra is a hormone replacement therapy (HRT). It contains two active ingredients: estradiol (an estrogen hormone) and medroxyprogesterone (a progestin hormone). Tridestra tablets are used to treat menopausal symptoms in women. Tridestra is a prescription-only medicine.

How does it work?

As menopause occurs, women begin to produce less estrogen, resulting in a decrease in estrogen levels in the blood. As a result, the decrease in estrogen levels produces several uncomfortable symptoms. Tridestra is a period less therapy, which means that you will not experience monthly bleeding with this treatment.

The benefits of Tridestra are thanks to the components it contains, two active ingredients, conjugated estrogens, which complement the lack of estrogens, helping to reduce the symptoms of menopause. The second principle is medroxyprogesterone acetate. For women who have not had a hysterectomy, increased estrogen levels can stimulate the growth of the uterine lining, which can cause uterine cancer. The inclusion of progesterone is done to counteract the effects of estrogen on the uterine lining, which reduces the risk of cancer.

What are the benefits of taking it?

Women's ovaries produce less and less estrogen in the period until menopause, causing estrogen levels to drop. A drop in estrogen levels can cause bothersome symptoms. The most common menopause symptoms include:

  • Hot flushes;
  • Vaginal discomfort (dryness, pain, irritation);
  • Difficulty falling asleep or staying asleep;
  • Osteoporosis (decreased bone mass and density);
  • Night sweats;
  • Humor changes.

HRT restores hormonal balance. Helps alleviate menopausal symptoms. Tridestra is aimed at women who keep their uterus in good condition, as it contains a progestogen hormone that protects the endometrium from side effects. Tridestra causes withdrawal bleeding every three months.

How do I use it?

Tridestra is based on a quarterly cycle. Each package contains three numbered blisters.

Blister # 1 contains white tablets. These tablets are to be taken for the first 70 days and contain only estradiol.

Blister No. 2 contains blue tablets, to be taken from days 71 to 84. These tablets contain estradiol and medroxyprogesterone.

Blister No. 3 contains yellow tablets. These tablets are to be taken from days 85 to 91 and do not contain any active ingredient (placebo).

The quarterly cycle causes a withdrawal bleed every three months (between day 85 and day 91). Start the next pack (Blister 1) immediately after finishing the third blister, even if it continues to bleed.
