Why is this medication prescribed?

Femara is a brand name for the generic medication letrozole. It is primarily prescribed for two main purposes:

• Breast Cancer Treatment: Femara is often used in the treatment of breast cancer, specifically hormone receptor-positive breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by reducing the production of estrogen in postmenopausal women. Since estrogen can promote the growth of certain types of breast cancer, reducing its levels can help slow or stop the cancer’s progression.
• Fertility Treatment: Femara is sometimes used off-label to stimulate ovulation in women who are having difficulty conceiving. It can be an alternative or adjunct to other fertility medications like clomiphene citrate. Femara works by inducing ovulation through its effect on estrogen levels.

How should this medicine be used?

Femara (letrozole) is typically used in two main contexts: breast cancer treatment and fertility treatment. Here’s how it’s generally used in each scenario:

• Breast Cancer Treatment:
  • The usual dosage for treating breast cancer is 2.5 milligrams (mg) taken orally once daily.
  • It can be taken with or without food.
  • Femara is typically prescribed for a period of five years, but the duration of treatment may vary based on individual circumstances and medical advice.
  • It’s important to take Femara exactly as prescribed by your doctor. Do not adjust the dosage or stop taking it without consulting your healthcare provider.
• Fertility Treatment:
  • Femara may be used off-label to induce ovulation in women who are having difficulty conceiving.
  • The typical starting dose for fertility treatment is also 2.5 mg taken orally once daily.
  • It’s usually taken for five days, starting on the third to seventh day of the menstrual cycle.
  • As with breast cancer treatment, Femara can be taken with or without food.
  • Your doctor will monitor your response to the medication and may adjust the dosage or treatment duration as needed.

Regardless of the reason for use, it’s important to follow your doctor’s instructions carefully when taking Femara. They will determine the appropriate dosage, timing, and duration of treatment based on your individual medical history and needs. It’s also essential to discuss any concerns or potential side effects with your doctor while taking Femara.

Other uses for this medicine

Some other potential uses of Femara include:

• Endometriosis: Femara may be used off-label to help manage endometriosis, a condition where tissue similar to the lining of the uterus grows outside the uterus, causing pain and other symptoms.
• PCOS (Polycystic Ovary Syndrome): Femara may be used off-label in women with PCOS to induce ovulation and help them conceive.
