Letrozole 5mg Tablet

Letrozole 5mg Tablet is a prescription oral medicine containing 5mg letrozole, an aromatase inhibitor used in breast cancer treatment. The 5mg strength is commercially marketed by several Indian pharmaceutical suppliers, while major reference products such as Femara® are marketed as 2.5mg tablets. Exact indications and approved strengths vary by country.

Main Uses

Letrozole is used in approved treatment protocols for hormone-dependent breast cancer, particularly in postmenopausal women. Current U.S. and UK labeling describes 2.5mg letrozole as the standard licensed tablet strength.

Some commercial 5mg products in India are also marketed with breast-cancer and other uses; the exact indication and dosing should follow the prescribing information for the particular 5mg product and jurisdiction.

How Letrozole Works

Letrozole inhibits the aromatase enzyme involved in estrogen production. Lower estrogen levels can reduce hormonal stimulation of estrogen-sensitive breast cancer cells.

Generic Product & Femara® Relationship

Letrozole 5mg is a generic active-ingredient product, not a 5mg version of Femara®. Femara® contains letrozole, but current U.S. and UK reference-product information identifies Femara as a 2.5mg tablet. Generic 5mg products can differ in manufacturer, excipients, tablet appearance and packaging.

Availability & Ordering

Commercial searches include Letrozole 5mg Tablet, Letrozole 5mg price, generic Letrozole 5mg, Letrozole 5mg tablets, Letrozol 5 mg, létrozole 5 mg, and レトロゾール 5mg. Current Indian listings include Letrosure 5, Lzetri 5, Letzol 5 and other 5mg letrozole products.

Availability, prescription requirements and authorized strengths differ by destination country.

Safety Information

Letrozole can cause adverse effects including hot flashes, joint or musculoskeletal symptoms, fatigue and dizziness. Reduced estrogen levels can also affect bone health. Current product information recommends appropriate clinical monitoring, particularly during longer-term treatment.

Do not start, stop or change the strength of letrozole without medical guidance.
