Letrozole Tablets – Letrozole is a medication that comes in tablet form. Letrozole is in a class of medications called nonsteroidal aromatase inhibitors. This medication is as hormone therapy for breast cancer or is used to treat certain types of breast cancer (such as hormone-receptor-positive breast cancer) in women after menopause. Letrozole is also used to help prevent the cancer from returning. Some breast cancers are made to grow faster by a natural hormone called estrogen. Letrozole decreases the amount of estrogen the body makes and helps to slow or reverse the growth of these breast cancers. 

Uses of Letrozole Tablets

Letrozole is primarily known as a medication used in the treatment of breast cancer. However, it also has off-label uses in other medical conditions. Below are some of its uses mentioned:

  • Letrozole tablets are commonly prescribed to postmenopausal with hormone receptor-positive breast cancer to reduce the risk of recurrence. It works by inhibiting the enzyme aromatase that reduces the estrogen production in the body, thus slowing or stopping the growth of cancer cells that need estrogen to grow.
  • Letrozole is sometimes used off-label to induce ovulation in women with infertility issues, particularly in cases of polycystic ovary syndrome (PCOS). It is often used as an alternative to clomiphene citrate (Clomid) because it can be more effective in certain situations and has fewer side effects.
  • Letrozole may be prescribed off-label in men with gynecomastia (enlargement of breast tissue in males), particularly when the condition is caused by an imbalance of estrogen and testosterone.
  • Letrozole may be used off-label in the management of endometriosis, a condition where tissue similar to the lining of the uterus grows outside the uterus, leading to pain and other symptoms. It may help by reducing estrogen levels and thus decreasing the growth of endometrial tissue.
  • Some athletes and bodybuilders have used letrozole to reduce estrogen levels and prevent estrogen-related side effects, such as water retention and gynecomastia when using anabolic steroids.

Note: It’s important to note that letrozole should only be used under the supervision of a qualified healthcare professional.
