How Valestra 1 works
Valestra 1 is an estrogen (female sex hormone). In women who are undergoing or have attained menopause, it prevents symptoms such as hot flushes, night sweats and mood swings. It also prevents the bones from becoming porous and fragile (osteoporosis).

Mode of Action
Estradiol is a naturally occurring oestrogen. Oestrogens are responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. They modulate the pituitary secretion of gonadotrophins, LH and FSH through a negative feedback system.
Precaution
Conditions exacerbated by fluid retention; hypercalcaemia, cerebrovascular diorders, coronary artery disease, gall bladder diseases; lipid effects; familial defects of lipoprotein metabolism. May increase BP, risk of venous thromboembolism, breast cancer, benign hepatic adenoma, endometrial cancer and size of preexisting uterine leiomyomata. Dosage should be reduced in hepatic impairment.

Pregnancy Category Note
Pregnancy
Therapy not indicated for use in pregnancy; there are no data with use in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to combined hormonal contraceptives (estrogen and progestins) before conception or during early pregnancy
Lactation
Therapy not indicated for use in females of reproductive potential; estrogens present in human milk and can reduce milk production in breast-feeding females; reduction can occur at any time but is less likely to occur once breast-feeding is well- established
Interaction
CYP1A2 and CYP3A4 inducers e.g. aminoglutethimide, carbamazepine, phenobarbital, and rifampin may decrease the effects of estradiol. May enhance the effects of hydrocortisone and prednisolone when used together.
