Indications & Clinical Uses

Letrozole is used in the management of hormone‑dependent breast cancer, targeting estrogen‑driven disease pathways.

  • Estrogen receptor‑positive breast cancer in postmenopausal women: reduces tumor progression and improves disease control.
  • Adjuvant therapy for early‑stage ER+ breast cancer: lowers the risk of recurrence after surgery.
  • Metastatic breast cancer in postmenopausal women: helps control disease spread and prolongs survival.

How It Works

  • Letrozole reversibly inhibits the aromatase enzyme, which converts adrenal and ovarian androgens into estrogens. By blocking this peripheral conversion, systemic estrogen levels decline, depriving estrogen‑dependent tumor cells of a growth stimulus and thereby slowing or halting tumor proliferation.

Side Effects

Letrozole may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

  • Hot flashes: sudden feeling of warmth, often with sweating.
  • Joint and muscle pain: aching or stiffness in limbs.
  • Fatigue: persistent tiredness not relieved by rest.
  • Nausea: mild to moderate upset stomach.
  • Headache: pressure or throbbing pain.
  • Dizziness: light‑headed sensation.

Serious or Rare Side Effects

  • Severe liver injury: jaundice, elevated enzymes.
  • Bone fracture: increased risk due to lowered estrogen.
  • Pulmonary embolism: sudden shortness of breath, chest pain.
  • Allergic reaction: rash, swelling, or anaphylaxis.
  • Elevated cholesterol: significant rise in lipid levels.
  • Cardiac arrhythmia: QT interval prolongation.

Precautions & Warnings

When prescribing Letrozole, clinicians should consider several safety measures and monitoring requirements.

  • Pregnancy contraindication: avoid use in pregnant women (Category X).
  • Bone health monitoring: assess bone mineral density periodically.
  • Liver function: check hepatic enzymes before and during therapy.
  • Cardiovascular risk: evaluate history of thrombosis or heart disease.
  • Premenopausal status: not indicated for women who are not postmenopausal.
  • Store at below 25°C: keep in the original pack, protect from moisture.

Avoid Interactions

Letrozole can affect the pharmacokinetics of other medicines; awareness of key interactions helps avoid adverse outcomes.

Major Interactions (Avoid)

  • Concomitant estrogen therapy: may counteract letrozole's effect.
  • Strong CYP3A4 inducers (e.g., rifampin, carbamazepine): reduce plasma concentrations.
  • Tamoxifen: antagonistic action on estrogen pathways.

Moderate Interactions (Monitor Closely)

  • Warfarin: potential increase in anticoagulant effect.
  • Statins: possible alteration of lipid‑lowering efficacy.
  • Glucocorticoids: may enhance bone loss risk.
  • SSRIs: potential additive effect on dizziness.
  • Antihypertensives: monitor blood pressure changes.

Frequently Asked Questions

Letrozole Manx Healthcare is indicated for the treatment of estrogen receptor‑positive breast cancer in postmenopausal women. It is used as adjuvant therapy after surgery, as well as in metastatic disease to help control tumor growth.

Letrozole works by reversibly inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens in peripheral tissues. This inhibition lowers circulating estrogen levels, depriving hormone‑sensitive cancer cells of a key growth stimulus.

The dose of letrozole is determined by the prescribing clinician based on the patient’s clinical condition, renal and hepatic function, and treatment goals. The prescriber sets the appropriate regimen and may adjust it during therapy.

Letrozole is classified as Pregnancy Category X, meaning it is contraindicated during pregnancy because it can cause fetal harm. It is also not recommended for breastfeeding mothers, as it may pass into breast milk and affect the infant.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and the necessary import documentation.

Letrozole, an aromatase inhibitor, lowers estrogen production, whereas tamoxifen is a selective estrogen receptor modulator that blocks estrogen receptors. Letrozole is generally preferred for postmenopausal patients because it provides more complete estrogen suppression, while tamoxifen is often used in premenopausal women or when an estrogen‑blocking approach is required.

Letrozole tablets should be stored at temperatures below 25 °C, in the original container, protected from moisture and direct sunlight. Keep the product out of reach of children and do not use if the packaging is damaged.

Letrozole is taken orally, usually once daily, with or without food. The tablet should be swallowed whole with a glass of water and not chewed or crushed.

Serious risks include severe liver injury, bone fractures due to decreased estrogen, pulmonary embolism, and rare allergic reactions such as anaphylaxis. Patients should be monitored regularly for signs of these conditions, and therapy should be discontinued if they occur.

Letrozole should not be used by pregnant or breastfeeding women, premenopausal women, patients with known hypersensitivity to letrozole or any component of the formulation, and individuals with severe liver impairment without appropriate medical supervision.
