Terpafen Tablets contain Clomifene Citrate, a selective estrogen receptor modulator (SERM). Clomifene Citrate is a non-steroidal anti-estrogen used to treat infertility in women who have difficulty becoming pregnant. It works by stimulating the release of hormones necessary for ovulation. Terpafen Tablets are prescribed to women who have trouble ovulating on their own, helping to induce ovulation and increase the chances of conception.
