What is letrozole 2.5 mg used for?
Letrozole tablets (2.5 mg) are used to treat certain types of hormone receptor–positive breast cancer, most commonly in postmenopausal people. The drug lowers estrogen levels in the body, which can slow or stop the growth of estrogen-sensitive tumors.
What breast cancer types does it treat?
Letrozole is used in hormone-sensitive breast cancer settings such as:
- Early breast cancer (adjuvant treatment after surgery) to reduce recurrence risk
- Advanced or metastatic breast cancer (for people whose cancer has progressed)
How does letrozole work in the body?
Letrozole is an aromatase inhibitor. It blocks the enzyme aromatase, which helps produce estrogen. By reducing estrogen production, it makes it harder for estrogen-receptor–positive cancer to grow.
Is it used only for breast cancer?
Based on the information provided, the established use for letrozole tablets is breast cancer treatment. If you saw letrozole mentioned for another condition, tell me the context (for example, fertility/PCOS or a different diagnosis) and I can help match the likely intended use.
How is letrozole 2.5 mg usually taken?
A common dose is 2.5 mg by mouth once daily for breast cancer treatment. Your exact dosing schedule can vary based on your diagnosis and your doctor’s plan.
What should patients watch for?
Because letrozole lowers estrogen, common side effects can include hot flashes, joint or muscle pain, fatigue, and increased risk of bone thinning. If you have questions about side effects or safety, share your age and whether you are postmenopausal.
