What are letrozole 2.5 mg film-coated tablets?
Letrozole 2.5 mg film-coated tablets are a prescription medicine. They belong to a group called aromatase inhibitors. These medicines lower estrogen levels in the body.
Lowering estrogen can help slow the growth of some breast cancers, especially cancers that are hormone receptor-positive. The original content also notes that letrozole may be used in fertility treatment plans in some settings.
What are letrozole 2.5 mg tablets used for?
- Breast cancer treatment: Used mainly for hormone receptor-positive breast cancer in postmenopausal women.
- Reducing estrogen activity: By lowering estrogen, it can help slow the growth of estrogen-sensitive tumors.
- Fertility treatment in some cases: It may be used in certain treatment plans to help induce ovulation.
Because treatment goals differ, the reason for use should always be confirmed with the prescribing clinician.
How does letrozole work?
Letrozole blocks the aromatase enzyme, which is involved in making estrogen. With less estrogen available, some breast tumors may grow more slowly.
This is why the medicine is mainly associated with hormone-sensitive breast cancer treatment. In fertility care, it may be used for a different purpose under specialist supervision.
What are the common side effects?
The original content lists the following common side effects:
- Hot flashes
- Joint pain
- Fatigue

Side effects can vary from person to person. If symptoms are severe, persistent, or worrying, they should be discussed with a healthcare professional.
How is letrozole usually taken?
The original content states that letrozole is typically taken once daily, with or without food. It also notes that the medicine should be taken consistently and exactly as prescribed.
If a dose is missed, the original content advises taking it when remembered unless it is nearly time for the next dose, in which case the missed dose should be skipped. For personal instructions, always check the prescription label or official leaflet.
What should be checked before taking letrozole?
- Medical history: Tell the prescriber about any relevant health conditions, including heart or liver problems.
- Other medicines: Share a full list of prescription medicines, over-the-counter products, and supplements.
- Pregnancy status: Letrozole should not be used during pregnancy, and contraception may be advised during treatment.
These points help the healthcare team assess whether the medicine is appropriate and how it should be monitored.
Are there interactions with letrozole?
The original content highlights possible interactions with:

Because interaction risk depends on the full medicine list, it is important to review all treatments with a doctor or pharmacist before use.
