Clomid tablets contain the active ingredient clomifene citrate (previously spelt clomiphene in the UK). (NB. Clomifene is also available without a brand name, ie as the generic medicine.)
Clomifene works by causing an increase in the levels of hormones in the female body which control the development and release of an egg. These hormones are released from the pituitary gland in the brain and are known as follicle stimulating hormone (FSH) and luteinising hormone (LH). FSH stimulates the ovaries and LH causes the release of an egg from the ovaries (ovulation).
Oestrogen normally causes the brain to stop releasing FSH and LH following ovulation, as part of the normal menstrual cycle. It does this by acting on receptors in a part of the brain called the hypothalamus, which sends messages to the pituitary gland.
Clomifene works by blocking the oestrogen receptors in the hypothalamus. This stops oestrogen from acting on these receptors, and therefore stops the message being sent to the pituitary gland. This results in the release of more FSH and LH from the pituitary gland. The increase in these hormones increases the chances of egg development and ovulation.
Clomifene is used to stimulate ovulation in women whose infertility is due to problems with ovulation.
