Letrozole

Uses

Letrozole is used in the treatment of breast cancer.

How it Works

How Letrozole works Letrozole is an aromatase inhibitor that decreases the amount of estrogen, a natural female hormone, produced in the body. This reduction in estrogen can slow down or stop the growth of certain breast cancers that rely on estrogen for their growth.

Side Effects

Common side effects of Letrozole include night sweats, bone pain, cough, shortness of breath, fatigue, weight gain, hot flushes, edema (swelling), flushing (a sense of warmth in the face, ears, neck, and trunk), diaphoresis, bone fractures, hypercholesterolemia (high cholesterol), joint pain, back pain, weakness, dizziness, nausea, osteoporosis, and joint inflammation.

Expert Advice

  • You have been prescribed Letrozole for the treatment of breast cancer.
  • It can be taken with or without food.
  • Do not drive or engage in activities requiring concentration until you understand how Letrozole affects you.
  • It may cause increased sweating and hot flushes.
  • To stay comfortable, try to wear light and airy clothing.
  • Your doctor may regularly monitor your cholesterol levels and bone mineral density (BMD), as Letrozole can affect these levels.
  • Do not take Letrozole if you are pregnant or breastfeeding.

Frequently asked questions

Letrozole, an anti-estrogen drug, works by blocking the aromatase enzyme, which reduces estrogen production in the body. Since estrogen can stimulate the growth of certain breast cancers, lowering its levels may help prevent cancer progression.

While the frequency typically decreases as your body adjusts, some individuals may continue to experience symptoms during and after treatment. Consult your doctor for management options if it becomes bothersome.
Serious side effects of Letrozole, which occur infrequently, may include stroke, angina, heart attack, blood clots, cataracts, osteoporosis, and severe skin reactions.
