5 mg tablet once daily. In the adjuvant setting, the intended duration of treatment is 5 years. In the extended adjuvant setting, treatment with M-LETROZOLE is intended for 5 years and should be initiated within 3 months of completion of approximately 5 years of prior standard adjuvant tamoxifen therapy.

Special populations Hepatic impairment:
No dose adjustment of M-LETROZOLE is required for patients with mild to moderate hepatic impairment (Child-Pugh score A or B). Insufficient data are available to recommend a dose adjustment in breast cancer patients with severe hepatic impairment (Child-Pugh C).
However, since letrozole elimination depends mainly on intrinsic metabolic clearance, caution is recommended. 3 Pharmacokinetics).
Renal impairment:
No dosage adjustment is required for patients with renal impairment with a creatinine clearance (CLcr) ≥10 mL/min. 3 Pharmacokinetics).
Pediatrics (< 18 years of age):
Letrozole is contraindicated in children and adolescents. The safety and efficacy of letrozole in children and adolescents (under 18 years of age) have not been established.
Geriatrics ( 65 years of age):
No dose adjustment is required for elderly patients. 3 Pharmacokinetics, Absorption). 5 Missed Dose The missed dose should be taken as soon as the patient remembers. However, if it is almost time for the next dose, the missed dose should be skipped, and the patient should go back to the regular dosage schedule.

Of the 19 deaths attributed to a cardiovascular cause in the placebo arm, 12 occurred in the group of 1026 patients who did not switch to letrozole after study unblinding, and 7 occurred in the group of 1551 patients who switched to letrozole.
A total of 7 patients died from a stroke – 6 in the letrozole arm and 1 after switching from placebo to letrozole after study unblinding. Driving and operating machinery No studies on the effects of letrozole on the ability to drive and use machines have been performed.

Endocrine and Metabolism Hyperlipidemia:
The use of aromatase inhibitors, including M-LETROZOLE, may increase lipid levels. 6% of patients treated with tamoxifen. In a smaller study (D2407) comparing 2 years of adjuvant treatment with letrozole or tamoxifen, significant differences were observed between treatments at all time-points in total cholesterol, LDL cholesterol and the HDL: LDL ratio in favour of tamoxifen.
Clinically relevant changes in total cholesterol at 2 years occurred significantly more often for patients treated with letrozole (17%) than with tamoxifen (5%). Monitoring of serum cholesterol is advised for patients treated with M-LETROZOLE.

Monitoring and Laboratory Tests Plasma Lipids:
Women should have their cholesterol levels assessed and managed according to current clinical practice and guidelines (see 7 WARNINGS & PRECAUTIONS- Endocrine and Metabolism).
Bone Mineral Density:
Monitoring of overall bone health is recommended during treatment with M- LETROZOLE. (See 7 WARNINGS & PRECAUTIONS- Musculoskeletal). In patients whose menopausal status is unclear or who become amenorrheic after chemotherapy, luteinising hormone (LH), follicle- stimulating hormone (FSH) and/or estradiol levels should be measured before initiating treatment with M-LETROZOLE and regularly during the first 6 months of treatment.

3 Pharmacokinetics). 5 OVERDOSAGE Isolated cases of letrozole overdose have been reported. In these instances, the highest single dose ingested was 125 mg or 50 tablets. While no serious adverse events were reported in these cases, because of the limited data available, no firm recommendations for treatment can be made.
In single dose studies the highest dose used was 30 mg, which was well tolerated; in multiple dose trials, the largest dose of 10 mg was well tolerated. In general, treatment of overdose with letrozole should be supportive and symptomatic.
Vital signs should be monitored in all patients. Complete blood count (CBC) and liver function tests should be monitored in symptomatic patients. Fluid and electrolyte status should be monitored in patients with significant vomiting and/or diarrhea.
Administration of activated charcoal may be appropriate in some cases.
