What is letrozole 2.5 mg, and what is it used for?
Letrozole 2.5 mg is a hormone (endocrine) medicine used to treat breast cancer in people after menopause. It works by lowering estrogen levels, which can slow or stop estrogen-driven tumor growth.
In practice, letrozole is prescribed for early breast cancer (often as adjuvant therapy), as well as for advanced or metastatic hormone-receptor–positive disease.
How is letrozole 2.5 mg usually taken?
The common dose is one tablet of 2.5 mg by mouth once daily. Your exact schedule should follow your prescriber’s instructions and the specific product label you receive.
If you miss a dose, take it when you remember unless it is close to the time of the next dose. Do not double up.
What are common side effects patients report with letrozole?
Common side effects include symptoms related to lower estrogen, such as hot flashes, joint or muscle pain (arthralgia/myalgia), fatigue, and headaches. Some people also report vaginal dryness or thinning, and mood changes.
More serious risks can include bone thinning (osteoporosis) and increased fracture risk over time, which is why clinicians often monitor bone health during long-term therapy.
Does letrozole 2.5 mg affect bones, and what monitoring is typical?
Yes. Lower estrogen can reduce bone mineral density. Many treatment plans include:
- Baseline and follow-up bone density checks (DEXA scans)
- Calcium and vitamin D guidance
- Possible bone-protecting treatment for higher-risk patients, depending on age, prior fractures, and baseline bone density
Are there important drug interactions?
Letrozole has potential interaction considerations with medications that affect drug metabolism, and with hormone-related therapies. Always provide your full medication list (including supplements and over-the-counter products) to your pharmacist or prescriber so they can check compatibility.
