Climen general information
What is Climen used for?
Climen tablets are a two-phase hormonal preparation that is used in hormone replacement therapy (HRT) for women with an intact uterus, used to substitute for a lack of oestrogen production by the ovaries during menopause. Climen tablets help relieve symptoms of menopause caused by oestrogen deficiency, such as hot flushes, night sweats, sleeplessness, vaginal dryness, headaches, mood swings, lack of concentration and loss of energy; while at the same time protecting against endometrial cancer (cancer of the lining of the uterus). Climen tablets also are also used to help prevent postmenopausal bone loss (osteoporosis) and reduce risk of fracture. Climen tablets are not intended for use as a contraceptive, as they do not prevent ovulation.
How does Climen work?
Climen tablets are a two-phase sequential hormone replacement therapy (HRT) and comprise a mixture of oestrogen only tablets followed by a combination of oestrogen and progestogen tablets. Estradiol is the most active form of natural oestrogen and is the female steroid hormone produced by the ovaries that binds to specific receptors inside oestrogen-responsive cells and stimulates them to make proteins involved in several aspects of female secondary characteristics including regulating the menstrual cycle. Oestrogen also has several other actions in various metabolic processes including maintaining bone mass and lipid (fat) metabolism. Cyproterone is a derivative of progesterone and has weak progestational activity (acts like progesterone); it is also an anti-androgen. Although androgens (like testosterone) are considered primarily male hormones, women also produce androgens, although in much smaller amounts, which in women are needed for puberty related changes like pubic hair growth, preventing bone loss, libido and for the production of oestrogen. Progesterone in pre-menopausal women acts on the endometrium (lining of the uterus) converting the proliferating phase to the secretory phase. This causes the endometrium, which has thickened in response to oestrogen during the first half of the cycle, to stop growing and start secreting hormones and other proteins needed to maintain a pregnancy, if conception occurs; if not, levels of oestrogen and progesterone fall and the endometrium is shed (menstruation). Cyproterone in Climen tablets works in the same way, but in menopausal women its role is to prevent excess growth of the endometrium in response to the oestrogen present in Climen tablets and this helps prevent endometrial cancer. The sequential hormone combinations in Climen tablets simulate a normal 28-day cycle; the estradiol component provides continuous oestrogen replacement for 21 days and the cyproterone component counteracts the effect of oestrogen on the endometrium for days 12-21. For the final 7 days of a 28-day cycle when you are not taking any tablets, you may have a withdrawal bleed as these are hormone-free days.

Treating symptoms of menopause with Climen
Climen tablets are a two-phase hormonal preparation that is used in hormone replacement therapy (HRT) for women with an intact uterus. Estradiol valerate, an oestrogen precursor, substitutes for the lack of oestrogen production by the ovaries that happens during menopause, to relieve symptoms of menopause caused by oestrogen deficiency, such as hot flushes, night sweats, sleeplessness, vaginal dryness, headaches, mood swings, lack of concentration and loss of energy. Oestrogen also has several other beneficial actions in various metabolic processes including bone turnover, and helps prevent postmenopausal bone loss (osteoporosis) and reduce risk of fracture. Cyproterone is a progesterone derivative that has weak progestational activity (acts like progesterone) and prevents excess growth of the endometrium (lining of the uterus) in response to oestrogen and protects against endometrial cancer.
Climen for transgender hormone therapy
Climen tablets contain a combination of estradiol valerate a precursor of oestrogen, and cyproterone acetate, which is a derivative of progestagen and is also an anti-androgen. The cyproterone component can be used as a substitute for spironolactone as the anti-androgen component of transgender feminising hormone therapy for male to female transsexuals, if small doses of anti-androgen are required.
