About Letrozen 5 Tablet

Letrozen 5 Tablet is a prescription oral tablet used primarily to treat certain types of breast cancer in women who have already gone through menopause. It is specifically prescribed for hormone-receptor-positive breast cancers, which rely on hormones to grow. By lowering hormone levels in the body, this medicine helps slow down or stop the growth of cancer cells.

For this medication to work effectively, you must take it consistently at the same time every day. You can take this tablet with or without food, as eating does not affect how the medicine is absorbed. Combining this treatment with a balanced diet and regular physical activity can help support your body and manage potential side effects.

While taking Letrozen 5 Tablet , you may experience mild side effects such as hot flashes, joint pain, or feeling unusually tired. While these are common, you should contact your doctor right away if you experience serious symptoms like severe chest pain, sudden shortness of breath, or signs of liver damage such as yellowing of your eyes or skin.

Do not take this if you are pregnant, breastfeeding, or have not yet gone through menopause. It is important to talk to your doctor before starting this medicine if you have a history of bone loss, high cholesterol, liver problems, or severe kidney disease.

This medicine can interact with other treatments, especially therapies that contain oestrogen, such as birth control pills or hormone replacement therapy, which can make this medication less effective. Older adults can safely take this medication, but your doctor will monitor your health closely during treatment to ensure your safety.

How Letrozen 5 Tablet Works

Many breast cancers in postmenopausal women are fuelled by the hormone oestrogen. Even after menopause, the body continues to produce small amounts of oestrogen by converting other hormones using a natural enzyme called aromatase. Letrozen 5 Tablet works by blocking this aromatase enzyme. By stopping this conversion process, the medication significantly lowers the amount of oestrogen circulating in your body. Without a sufficient supply of oestrogen, hormone-receptor-positive breast cancer cells lose their primary source of growth, causing them to shrink or stop multiplying.
