1. Basic product information

Brand availability and pack details can vary. Always follow the instructions provided with your product and your healthcare team’s plan.

2. How Femara works (mechanism of action)

Femara (letrozole) belongs to a group of medicines called aromatase inhibitors. In the body, the enzyme aromatase helps produce oestrogen from other hormones (especially after menopause).

Letrozole blocks aromatase, which reduces oestrogen levels. Many breast cancers grow in response to oestrogen. By lowering oestrogen, Femara helps slow cancer growth and reduce the chance of recurrence in appropriate patients.

• Primary action: inhibits aromatase
• Result: decreased oestrogen production
• Clinical goal: hormone suppression for oestrogen‑dependent breast cancer

3. Pharmacokinetics (how the body processes Femara)

“Pharmacokinetics” describes absorption, distribution, metabolism, and elimination. While individual results vary, key points for letrozole include:

• Absorption: Letrozole is absorbed after oral administration and reaches therapeutic levels within hours.
• Peak levels: Blood concentrations typically peak about 2 hours after dosing.
• Distribution: It distributes throughout the body, including breast tissue.
• Metabolism: Mainly metabolised in the liver (primarily via CYP pathways).
• Elimination: Letrozole is cleared from the body with a moderate half‑life, supporting once‑daily dosing.

Your healthcare professional may adjust the treatment plan based on kidney or liver function and other medications you take.

4. Typical use and treatment settings

Femara is used for hormone‑dependent breast cancer. Depending on the stage and prior treatment, it may be used for:

• Early breast cancer (adjuvant treatment): after surgery to help reduce recurrence risk.
• Extended adjuvant therapy: continuing treatment after initial adjuvant therapy.
• Locally advanced or advanced breast cancer: to control disease progression.
• Neoadjuvant settings may be considered in selected cases under specialist care.

The exact indication, duration, and combination with other therapies depend on tumour characteristics, menopausal status, and previous treatments.

5. Indications (what Femara is prescribed for)

In general terms, letrozole is indicated for the treatment of oestrogen receptor (ER)‑positive breast cancer in postmenopausal women, including:

• Early breast cancer (adjuvant therapy) to lower the risk of recurrence.
• Breast cancer after prior hormone therapy in appropriate settings.
• Advanced disease (locally advanced or metastatic).
• Extended adjuvant treatment in selected patients.

Some clinical situations may involve broader eligibility criteria depending on the individual’s medical history. Your treating team will determine suitability.

6. Dosing: how Femara is usually taken

For many breast cancer treatment plans, Femara is taken as a once‑daily tablet. Common regimens include:

• 2.5 mg once daily is the most widely used standard dose.

The duration can vary from months to years, particularly for early or extended adjuvant therapy. Treatment is often long‑term in breast cancer settings.

Important: Always follow the schedule provided by your healthcare professional and the instructions on the pack. Do not change your dose without medical guidance.

Missed dose

• If you miss a dose, take it when you remember unless it is close to the time for your next dose.
• Do not take a double dose to make up for a missed tablet.
• If you are unsure, ask your pharmacist for advice.

7. Timing: when to take Femara

Femara is typically taken at the same time each day to help maintain steady medicine levels and support adherence. Many people find bedtime or breakfast convenient—choose a time you can consistently keep.

• Consistency helps: aim for once daily with similar timing.
• No special “fasting” requirement: letrozole can generally be taken with or without food.
• If you experience side effects: timing may sometimes help (discuss options with your healthcare team).

8. Food interactions and diet considerations

Food is not expected to significantly change the overall effectiveness of letrozole. In many patients, Femara can be taken regardless of meals.

That said, if a particular meal triggers nausea or reflux for you, consider taking your dose with food or at a time that suits your routine. Always prioritise tolerability and adherence.

• Generally: take with or without food.
• Practical tip: if you get stomach discomfort, try a meal or snack.
• Bone health: consider a diet supportive of bone strength (calcium and vitamin D are often discussed with clinicians).

9. Alcohol interactions

Moderate alcohol intake is not always listed as a direct interaction with letrozole, but alcohol can affect:

• Side effects (e.g., fatigue, dizziness, sleep changes)
• Adherence (missed doses due to drinking or altered routine)
• Liver health (important since letrozole is processed in the liver)

If you choose to drink alcohol, consider limiting intake and discuss your individual safety with a healthcare professional—especially if you have liver conditions or other medications.

10. Medicine interactions (important to check)

Interactions depend on your overall medication list. Always inform your doctor and pharmacist about all medicines you take, including over‑the‑counter products and supplements.

Key interaction considerations

• Hormonal therapies: Combining aromatase inhibitors with other hormone therapies may not be appropriate unless specifically planned by your oncology team.
• CYP‑active medicines: Because letrozole is metabolised in the liver, medicines that affect liver enzymes may alter letrozole levels.
• Medicines that affect bone health: While not a “direct” interaction, your clinician may coordinate bone‑protective care.

Examples to discuss (not exhaustive)

• Certain antidepressants and antiepileptics
• Medicines for fungal infections or tuberculosis
• Some anticoagulants or antiplatelet medicines
• Herbal products (e.g., St John’s wort) may affect drug metabolism

If you start, stop, or change any medicine or supplement, check with your pharmacist to confirm it’s compatible with Femara.

11. Safety profile: common and serious side effects

Like all medicines, Femara can cause side effects. Many are manageable, and your healthcare team may recommend supportive measures. Seek medical advice promptly for severe or concerning symptoms.

Common side effects

• Hot flushes
• Joint pain or stiffness (arthralgia)
• Fatigue
• Headache
• Swelling (oedema) in some patients
• Muscle aches
• Nausea
• Reduced bone mineral density over time
• Vaginal dryness or related symptoms

Serious but less common warnings

• Bone health concerns: fractures can occur with long‑term aromatase inhibition. Monitoring may be recommended.
• Liver issues: unusual fatigue, dark urine, yellowing of skin/eyes, or severe abdominal pain should be assessed urgently.
• Severe allergic reactions: swelling of face/lips, difficulty breathing, or widespread rash require emergency care.
• Cardiovascular events: any chest pain, shortness of breath, or sudden neurological symptoms warrant urgent medical evaluation.

When to get urgent help

Call emergency services or seek urgent medical care if you have symptoms such as:

• Difficulty breathing or swelling of the face/tongue
• Chest pain, severe shortness of breath, fainting
• Signs of severe infection (high fever, confusion)
• Yellowing of skin/eyes (jaundice)
• Severe allergic rash with blistering or peeling

12. Practical use tips

Staying comfortable and consistent with treatment can improve outcomes. The tips below are practical and commonly used in breast cancer care.

Support for common symptoms

• Hot flushes: dress in layers, use a fan, avoid overheating, and discuss medication options if severe.
• Joint pain: gentle stretching, regular low‑impact exercise (walking, swimming), and physio support may help.
• Fatigue: pace activities, prioritise rest, and maintain light daily movement where possible.
• Vaginal dryness: non‑hormonal moisturisers/lubricants can be discussed; specialist advice is useful.

Bone protection and monitoring

Because aromatase inhibitors can reduce oestrogen and affect bone density, many patients benefit from:

• Baseline and follow‑up bone density scans (e.g., DEXA) as recommended.
• Calcium and vitamin D intake through diet and/or supplements if advised.
• Weight‑bearing exercise and fall‑prevention strategies.
• Bone‑strengthening medicines if your clinician recommends them.

Adherence and storage

• Take consistently once daily.
• Store at room temperature, protect from moisture and keep out of reach of children.
• Check the pack expiry date before use.

13. Alternative options (discuss with your clinician)

Several endocrine (hormone) therapy options exist for hormone‑dependent breast cancer. The best choice depends on your cancer features, stage, previous treatment, menopausal status, and tolerability.

Common alternatives to letrozole

• Other aromatase inhibitors: anastrozole, exemestane
• Selective oestrogen receptor modulators (SERMs): tamoxifen (in specific patient groups)
• Oestrogen receptor down‑regulators / selective therapies: depending on the clinical scenario (specialist‑guided)
• Additional cancer treatments: chemotherapy, targeted therapy, and/or radiotherapy depending on disease type

If you experience troublesome side effects on Femara, switching within the endocrine options may be considered. Never stop or switch on your own—ask your oncology team.
