What is letrozole 2.5 mg used for?
Letrozole 2.5 mg tablets are used to treat certain types of hormone receptor–positive breast cancer in postmenopausal women. The drug lowers estrogen levels, which can slow or stop the growth of some breast cancers that use estrogen to grow. [1]
Which breast cancer situations does it treat?
Letrozole is commonly used in:
- Early-stage hormone receptor–positive breast cancer, including as adjuvant (after surgery) or for extended adjuvant therapy in eligible patients. [1]
- Advanced or metastatic hormone receptor–positive breast cancer. [1]
How does letrozole work?
Letrozole is an aromatase inhibitor. It reduces estrogen production by blocking the aromatase enzyme, which helps convert other hormones into estrogen in the body. Lower estrogen can reduce stimulation of estrogen-sensitive breast cancer cells. [1]
Is letrozole used for anything other than breast cancer?
The provided information focuses on breast cancer uses. [1] If you’re asking about other conditions (for example, fertility-related uses), the correct dosing and safety depend on the specific situation and should be confirmed with a clinician.
What to know before taking it (practical considerations)
Because letrozole lowers estrogen, it can cause side effects related to low estrogen levels (such as hot flashes and joint or muscle pain). It can also affect bone density, so clinicians often consider bone health during treatment. [1]
